One way speed of light.

[olavisjo]

.
Many experiments claiming to test the one way speed of light have been performed, but on closer analysis they have been shown to measure the two way speed of light.

Is it possible to measure the one way speed of light?

[A Troubled Man]

It's not an easy thing to measure the speed of light on earth simply because of the requirements of the experiment, a very long distance between two points with only the vacuum of space between them.

But the OP was talking about one way speed and not just the speed of light. The one way speed would require the sender and reciever to be synchronized. And since time is relative, synchronisation is a matter of deciding whose clock we use and as such it is a matter of convention and cannot be measured in principle.

Then, there is the problem of signalling each point as to when photons are released to travel to the other point. Sure, we have the technology to do such an experiment, but the costs would be ridiculous. Since we have a very good understanding of electromagnetic radiation already, such an expensive experiment would be drastic overkill and would serve no real purpose to validate.

Surely the signal would travel as fast as the light we are trying to measure, and arrive at the same time as the photons arrive at the detector.

Yes, that is the issue with measuring the one way speed of light and even that it's been attempted, the results were null, showing it didn't violate SR.

The clocks need to be synced together before using, yes, but they can be compared after the experiment showing when the photons were released on one side and then captured by the other. Again, an expensive and elaborate experiment not really required.

[Divine Insight]

Sorry, far from it. There is nothing in GR explaining gravity to be the result of time dilation between the head and feet, or that a person in free fall is the one putting down ward forces on the earths surface. Pure nonsense.

That is precisely what Einstein's Field Equation is indeed describing. It's right there in front of you in his equation. How can you argue with that?

Einstein's mathematical description of gravity is a description of a warping of the fabric of spacetime. This difference in time has even been measured and scientifically verified to be precisely as Einstein's Equation predicts.

So this is experimentally verified science.

I've already showed you through Einstein's own gedanken experiment that the surface of the earth is accelerating up towards us just like the observer in the elevator. It's called the Equivalence Principle. If you actually claim to know GR, you would know this.

No, you're wrong. You haven't shown any such thing.

Yes, it was indeed Einstein's own gedanken experiment (thought experiment) that led him to the realization of the mathematical equivalency of the effects of acceleration and gravity. I don't argue with that at all. But that thought experiment is NOT General Relativity. That thought experiment was merely an insight that led Einstein down the road to eventually develop the equations of General Relativity.

I've already stated that the perceived effects of a body accelerating through a uniform spacetime field are precisely the same as the perceived effects that a stationary body will experience in a warped spacetime field.

What part of that do you not understand?

However, the perceived effects do not explain what is actually causing those affects. The Field Equations of Einstein's General Relativity describe the cause of these effects.

The case of an accelerating elevator in a uniform spacetime field is different from the case of a stationary observer in a non-uniform spacetime field, even though the perceived effects are the same.

And Einstein's Equations describe this perfectly.

You are either just trying to be difficult, or you are genuinely not comprehending what I'm saying.

All I'm saying is what should be obvious to anyone who understands Einstein's field equation. That equation is describing a warped fabric of spactime, and this is the cause of gravity.

It is not due to the earth's surface accelerating outward. The Earth would need to be getting exponentially bigger at a phenomenal rate if that were true.

You are confusing Einstein's original insight gained through his thought experiments with his final mathematical masterpiece of General Relativity.

His gendanken experiment was merely an insight that led him to eventually formulate General Relativity. It's not a description of the final product of General Relativity.

The surface of the Earth is not accelerating outward. It's stationary.

I'm done here. If wish to continue to argue on this point please find someone else to argue with.

The surface of the Earth is not accelerating outward. Period. That's simply wrong.

[A Troubled Man]

That is precisely what Einstein's Field Equation is indeed describing. It's right there in front of you in his equation. How can you argue with that?

Einstein's mathematical description of gravity is a description of a warping of the fabric of spacetime. This difference in time has even been measured and scientifically verified to be precisely as Einstein's Equation predicts.

So this is experimentally verified science.

I have no idea where get verified science from your explanation of gravity to be the result of time dilation between the head and feet, or that a person in free fall is the one putting down ward forces on the earths surface. Sorry dude, that's just pure nonsense.

But that thought experiment is NOT General Relativity. That thought experiment was merely an insight that led Einstein down the road to eventually develop the equations of General Relativity.

Nice contradiction.

I've already stated that the perceived effects of a body accelerating through a uniform spacetime field are precisely the same as the perceived effects that a stationary body will experience in a warped spacetime field.

What part of that do you not understand?

You said, gravity is the result of time dilation between the head and feet, and that a person in free fall is the one putting down ward forces on the earths surface. Where do you get that notion?

However, the perceived effects do not explain what is actually causing those affects. The Field Equations of Einstein's General Relativity describe the cause of these effects.

The cause is gravity, obviously.

The case of an accelerating elevator in a uniform spacetime field is different from the case of a stationary observer in a non-uniform spacetime field, even though the perceived effects are the same.

Yes, the effects are the same, they are indistinguishable, that is the point. Yet, you are arguing with me. Hilarious.

And Einstein's Equations describe this perfectly.

You are either just trying to be difficult, or you are genuinely not comprehending what I'm saying.

You simply have no idea what you're talking about. You have a false understanding.

All I'm saying is what should be obvious to anyone who understands Einstein's field equation. That equation is describing a warped fabric of spactime, and this is the cause of gravity.

It is not due to the earth's surface accelerating outward. The Earth would need to be getting exponentially bigger at a phenomenal rate if that were true.

Wow, I am truly amazed at your lack of comprehension skills. I keep telling you over and over that the earth is not getting bigger.

You are confusing Einstein's original insight gained through his thought experiments with his final mathematical masterpiece of General Relativity.

No, I'm not.

His gendanken experiment was merely an insight that led him to eventually formulate General Relativity. It's not a description of the final product of General Relativity.

Yes, it is.

The surface of the Earth is not accelerating outward. It's stationary.

Once again, your comprehension skills are not allowing you to see the obvious.

I'm done here. If wish to continue to argue on this point please find someone else to argue with.

I'm trying to explain GR to you as you have a false understanding.

The surface of the Earth is not accelerating outward. Period. That's simply wrong.

It is correct. Sorry, you that you don't have a very good understanding, nor can you even understand the Equivalency Principle.

[Divine Insight]

I keep telling you over and over that the earth is not getting bigger.

I thank you for the confirmation.

May your studies in GR continue to blossom.

Best regards.

[A Troubled Man]

I keep telling you over and over that the earth is not getting bigger.

I thank you for the confirmation.

May your studies in GR continue to blossom.

Best regards.

You still haven't show that gravity is caused by time dilation between the feet and head. That has got to be one of the funniest ones I've ever heard. Not to mention, it is a human in free fall that is exerting a force on the earth. Hilarious.

I guess we'll never hear that theory blossom.

[Divine Insight]

You still haven't show that gravity is caused by time dilation between the feet and head. I guess we'll never hear that theory blossom.

I already described it in my prior posts on this thread, complete with providing Einstein's field equation that describes it, and I was even kind enough to provide a graphic representation of that equation.

I can't imagine what more you would need before you can comprehend this very simple concept.

You've already confessed that the Earth isn't getting any bigger. Thus you have confessed that gravity is not being caused by the Earth's surface accelerating outward. Unless you think the Earth's surface can somehow miraculously accelerate outward without moving.

Also, in a gesture of social politeness I have already offered to agree to disagree with you in a civil friendly manner.

If you would like to believe that gravity is being caused by the surface of the earth accelerating outward, please be my guest.

I do not agree with your view on that. I am very confident that gravity is being caused by the the warping of the fabric of spacetime in the vicinity of the Earth precisely as Einstein's field equations predict and describe.

So I'm quite happy with my current understanding.

If you're happy with yours, we're done.

Best Regards.

[A Troubled Man]

I already described it in my prior posts on this thread, complete with providing Einstein's field equation that describes it, and I was even kind enough to provide a graphic representation of that equation.

That is entirely false, you did no such thing. Einsteins field equations DO NOT describe gravity as being caused by time dilation between the feet and head and it DOES NOT describe an object in free fall exerting a force. That is complete rubbish.

You never showed that because it is entirely false. You are free to show that in the equations, but they aren't there.

I can't imagine what more you would need before you can comprehend this very simple concept.

There's nothing to comprehend from what you claimed, nothing. Your understanding is false and has nothing to do with GR. It's that simple.

You've already confessed that the Earth isn't getting any bigger.

Those are YOUR words, not mine. I never said the Earth was getting bigger, YOU did. That is because you have yet to comprehend the Equivalence Principle to understand that gravity is indistinguishable from an accelerated surface.

Thus you have confessed that gravity is not being caused by the Earth's surface accelerating outward.

Neither has anything to do with one another, that is a result of the Equivalence Principle in which one cannot distinguish between gravity and an accelerated surface. This was brought into view with the elevator experiment which shows that an elevator under acceleration in space is indistinguishable from an elevator at rest in a gravitational field, hence the surface of the elevator is an accelerated surface.

Funny, how you can't comprehend the Equivalence Principle and must imagine the Earths surface getting bigger. Hilarious. That is exactly what a lay person would say who doesn't comprehend it.

Unless you think the Earth's surface can somehow miraculously accelerate outward without moving.

It doesn't, that is a result of your comprehension skills not understanding the Equivalence Principle. Simple really.

If you would like to believe that gravity is being caused by the surface of the earth accelerating outward, please be my guest.

That is exactly the way the Equivalence Principle works, dude.

I do not agree with your view on that.

Then, you don't agree with GR.

I am very confident that gravity is being caused by the the warping of the fabric of spacetime in the vicinity of the Earth precisely as Einstein's field equations predict and describe.

But, you have yet to show that gravity is being caused by time dilation between the feet and head and that an object in free fall exerts a force. Those are YOUR claims and you have yet to show them anywhere as being valid.

Do you deny these claims now? Why haven't you shown them to me in the equations?

So I'm quite happy with my current understanding.

It is false, so you probably shouldn't be telling people about it as you would be spreading misinformation, which is basically what you told me.

So, unless you can validate your claims AND you can show me that you actually do understand the Equivalence Principle, we can conclude you have no idea what you're talking about.

[A Troubled Man]

I disagree that the Earth's surface is accelerating up toward us. That's actually an incorrect metaphor of what's actually happening. The surface of the Earth is better thought of as being fixed. It doesn't need to accelerate up toward us. We are in a state of free fall, and the Earth's surface is fixed, and thus we are actually exerting a downward push on the surface of the Earth due to our state of free fall. So in a sense, we are exerting a force on the Earth rather than the other way around.

We're actually accelerating down toward it and this is what causes the effect of gravity.

Time is passing by slower at our feet than it is for our heads. It is this non-uniform time field that causes our bodies to accelerate downward.

So the Surface of the Earth is actually in precisely the same state we're in.
So it's our natural state of free fall that is causing us to stick to the surface of the Earth. Our bodies are desperately trying to get to the center of the Earth and the static surface of the Earth is merely preventing our bodies from making that free fall journey.

These articles will show that to be false...

"The key idea of general relativity, called the equivalence principle, is that gravity pulling in one direction is completely equivalent to an acceleration in the opposite direction. A car accelerating forwards feels just like sideways gravity pushing you back against your seat. An elevator accelerating upwards feels just like gravity pushing you into the floor."

http://www.pbs.org/wgbh/nova/physics/re ... osmos.html

"He proposed an experiment involving two elevators: one at rest on the ground on the Earth and another, far out in space away from any planet, moon, or star, accelerating upward with an acceleration equal to that of one Earth gravity (9.8 meters/second2). (Modern readers can substitute rocket ship'' for Einstein's elevator.)

http://www.astronomynotes.com/relativity/s3.htm

"The equivalence principle was Einstein's Newton's apple' insight to gravitation. His thought experiment was the following, imagine two elevators, one at rest of the Earth's surface, one accelerating in space. To an observer inside the elevator (no windows) there is no physical experiment that he/she could perform to differentiate between the two scenarios.

The equivalence principle is a fundamental law of physics that states that gravitational and inertial forces are of a similar nature and often indistinguishable."

http://abyss.uoregon.edu/~js/21st_centu ... lec07.html

"In a gravitational field (of small spatial extension) things behave as they do in a space free of gravitation, if one introduces into it, in place of an inertial system, a frame of reference accelerated relative to the former.

Inertia and gravity are phenomena identical in nature. From this and from the special theory of relativity it follows necessarily that the symmetric fundamental [metric] tensor gmn determines the metric properties of space, the inertial behavior of bodies in this space, as well as the gravitational effects."

[Divine Insight]

So, unless you can validate your claims AND you can show me that you actually do understand the Equivalence Principle, we can conclude you have no idea what you're talking about.

Who is the "we" you are referring to here Troubled Man?

As far as I can see you are the only person who is having a problem understanding General Relativity here.

You asked me to validate my claim. I feel that I have already done that sufficiently . However since you have not yet understood, I'll attempt very sincerely to try to explain this to you one more time. I'll go into some detail here in an attempt to explain it the best I can.

Here are the points I've already made thus far:

1. Gravity is not being caused by the acceleration of the Earth's surface in an outward or upward direction as you have suggested.

2. Yes, it's quite true that Albert Einstein had a revelation via a thought experiment that the effects caused by gravity are indistinguishable from the effects caused by a body such as an imaginary elevator accelerating in deep space far removed from any gravitational fields. Apparently this initial early revelation and thought experiment that Albert Einstein had is the focus of your misunderstanding of General Relativity.

I am not in disagreement with this at all. That is precisely the revelation that is given in just about every textbook you'll ever find on General Relativity 101.

That is the easiest way to begin to first understand where Albert Einstein is heading any how he began to create his mathematical description of General Relativity.

However, please understanding this: Einstein had this revelation quite early on. It was a revelation of equivalency of effect not a revelation of equivalency of cause. He could see that gravity produces precisely the same effects that you would experience if you were in an elevator that was accelerating in deep space where there is no gravitational field at all.

So allow me to put forth this forth facts. I'll number these facts for your for easy reference. Perhaps we can narrow down where your misunderstanding lies since you seem to be so intent on taking our disagreement to it's bitter end.


Fact 1. Einstein's revelation of an elevator accelerating in deep space is a revelation of equivalency of effect. Not a revelation of equivalency of cause.

Fact 2. Einstein had this revelation very early in his career, long before he had actually formulated General Relativity in a consistent mathematical way.

Fact 3. The final mathematical product that Einstein ultimately produced, (which is General Relativity) does not describe the cause of gravity to be due to a body accelerating through a uniform field of spacetime. Instead it describes a situation where stationary bodies are being affected by a distorted or warped fabric of spacetime.

Fact 4. The very notion of a fabric of a 4-dimensional spacetime that could be described by a single geometric field equation was not even in Albert Einstein's thoughts when he first thought about the equivalence of effects between being in a gravitational field and being in an accelerating elevator in deep space far removed from any gravitational field.

And please pay close attention to Fact #1. Equivalency of effect, is not the same as equivalency of cause.

Please let me know if you disagree with any of the above facts.

Einstein's initial revelation was a revelation of equivalence of effects, not an equivalency of cause. And this appears to me to be the crux of your misunderstanding. You appear to be under the misguided notion that if the effects are the same then the cause of the effects must be the same. That is simply wrong. You're not fully understanding what's going on in General Relativity if you believe that.

The effects produced are the same, but the cause of the effects are different. In the thought experiment, the cause of the effects is a body accelerating through a uniform field of spacetime. In the case of gravity the cause of the effects is a warping of the fabric of spacetime itself. The bodies in this case are indeed stationary. It's the fabric of spacetime that it warped in the vicinity that is the cause of the effects in this case. And this is what Einstein;s General Relativity ultimately shows, and precisely what his 4-dimentional field equation describes.

Just as I have been attempting to point out all along.

Fact 5. The earth is not getting bigger, (as you have already agree to). Therefore the surface of the earth cannot be accelerating outward to produce the effect of gravity.

The effect of gravity on planet earth is not due to the surface of the earth acceleration outward. The earth's surface is not exerting a force upon us due to it's accelerated motion. It's not moving at all.

On the contrary, we are "falling". Our bodies are in a state of "free fall" at all times. And what this actually means is that our bodies are constantly being accelerated downward. In fact, you don't even need to be touching the surface of the earth in order to experience the effect of gravity. If you climb up a ladder and step off you'll accelerate downward. But at that point you aren't even touching the earth's surface, so the force of gravity on you cannot be due to the earth's surface pushing on you.

And remember the earth's surface is not moving. It's not coming up to meet you, you are necessarily moving downward to fall upon it. Therefore you are the one who is exerting a downward force onto the earth's surface, not the other way around.

What does Einstein's field equation have to say about this? Well, Einstein's field equation shows that we exist in a non-uniform field of spacetime. The spacetime at your feet is distorted and warped and is different from the spacetime that exists at your head. Einstein's field equation also describes time as being part of this 4-dimensional field, and it shows that time is flowing by more slowly at your feet than it is at your head. If you have been spending most of your life standing up, then your head is actually older than your feet. A strange situation to be sure, but true none the less.

So the fabric of space is simply warped. And our constant acceleration toward the center of the earth is due to our bodies being accelerating downward. It's not due to the earth's surface accelerating upward to us. So ultimately we are exerting a downward force on planet earth, not the other way around.

That force is caused by the presence of the earth however. Because if it wasn't for the presence of the earth the fabric of spacetime would not be warped. So it is correct to say that the presence of the earth is the "cause" of this situation. But still it is your body that is producing a downward force on the surface of the earth, not the other way around. And the reason your body is doing this is because it exists in a warped field of spacetime.

So if you want to give an "origin" (or cause) to the force that we exert against the surface of the earth, that origin would be the fact that we reside in a warped field of spacetime.

As far as the time flowing slower at your feet than at your head, this too should be completely obvious to you if you have any understanding of General Relativity at all.

Fact 6. Gravity causes time to dilate. Time flows slower in a gravitational field (i.e. A field of warped spacetime) than it does in a deep space far removed from any gravitational field (i.e. A uniform field of spacetime)

With this realization you can also see that within a non-uniform (or warped) field of spacetime time flows more slowly at places that are more intensely warped relative to places that are not as warped. The gravity at your feet is stronger than the gravity at your head. In other words, spacetime is warped more at your feet than it is at your head. (assuming you're standing up of course) And it is this difference in this field of spacetime that causes your body to be accelerated downward.

Of course, this is not due solely to the time dilation. The space itself is also warped. But the dilation of time plays a role as well because space and time are intimately entwined as single fabric. You can't warp one without warping the other.

So there you go.

I'm not proposing any new or extraneous theories.

Everything I've described above is already well documented in Einstein's General Relativity and described mathematically by his spacetime field equation.

If you disagree with any of the facts I've listed above please let me know which ones you disagree with, and perhaps we can move forward from there.

[A Troubled Man]

As far as I can see you are the only person who is having a problem understanding General Relativity here.

Even though I provided sources that show your understanding to be false and everything I said to agree with it? LOL.

You asked me to validate my claim. I feel that I have already done that sufficiently .

You've done no such thing. The sources I provided showed them to be false.

Here are the points I've already made thus far:

1. Gravity is not being caused by the acceleration of the Earth's surface in an outward or upward direction as you have suggested.

The Equivalence Principle shows that to be completely correct as the surface of the Earth IS an accelerated surface, just like the surface of the elevator.

2. Yes, it's quite true that Albert Einstein had a revelation via a thought experiment that the effects caused by gravity are indistinguishable from the effects caused by a body such as an imaginary elevator accelerating in deep space far removed from any gravitational fields. Apparently this initial early revelation and thought experiment that Albert Einstein had is the focus of your misunderstanding of General Relativity.

No, it is something you obviously don't understand.

I am not in disagreement with this at all. That is precisely the revelation that is given in just about every textbook you'll ever find on General Relativity 101.

That is the easiest way to begin to first understand where Albert Einstein is heading any how he began to create his mathematical description of General Relativity.

However, please understanding this: Einstein had this revelation quite early on. It was a revelation of equivalency of effect not a revelation of equivalency of cause. He could see that gravity produces precisely the same effects that you would experience if you were in an elevator that was accelerating in deep space where there is no gravitational field at all.

And, that is exactly what I've been saying, why are you disagreeing? The Equivalence Principle is key to GR.

So allow me to put forth this forth facts. I'll number these facts for your for easy reference. Perhaps we can narrow down where your misunderstanding lies since you seem to be so intent on taking our disagreement to it's bitter end.

Or, most likely, we'll be pointing out your flaws of understanding.

Fact 1. Einstein's revelation of an elevator accelerating in deep space is a revelation of equivalency of effect. Not a revelation of equivalency of cause.

Irrelevant. Scientists don't yet know what causes gravity.

Fact 2. Einstein had this revelation very early in his career, long before he had actually formulated General Relativity in a consistent mathematical way.

Irrelevant, the Equivalence Principle is key to GR.

Fact 3. The final mathematical product that Einstein ultimately produced, (which is General Relativity) does not describe the cause of gravity to be due to a body accelerating through a uniform field of spacetime.

Those are your words, not mine. I never said that.

Instead it describes a situation where stationary bodies are being affected by a distorted or warped fabric of spacetime.

The bodies are not stationary, they are in free fall in an accelerated frame of reference.

Fact 4. The very notion of a fabric of a 4-dimensional spacetime that could be described by a single geometric field equation was not even in Albert Einstein's thoughts when he first thought about the equivalence of effects between being in a gravitational field and being in an accelerating elevator in deep space far removed from any gravitational field.

So what? Do you have a point?

And please pay close attention to Fact #1. Equivalency of effect, is not the same as equivalency of cause.

Those are your words, not mine. Irrelevant.

Please let me know if you disagree with any of the above facts.

The aren't facts, they make up a confused notion of GR.

Einstein's initial revelation was a revelation of equivalence of effects, not an equivalency of cause. And this appears to me to be the crux of your misunderstanding.

No, it is your misunderstanding based on your failed comprehension skills of what I said.

You appear to be under the misguided notion that if the effects are the same then the cause of the effects must be the same.

You appear to have comprehension issues, I never even remotely implied that.

That is simply wrong. You're not fully understanding what's going on in General Relativity if you believe that.

That is your misunderstanding, why would I believe that?

The effects produced are the same

Then, you agree with me.

, but the cause of the effects are different.

So what? I never stated any causes. That is your comprehension skills issue.

In the thought experiment, the cause of the effects is a body accelerating through a uniform field of spacetime. In the case of gravity the cause of the effects is a warping of the fabric of spacetime itself.

So what? What is your point?

The bodies in this case are indeed stationary.

They are in free fall.

It's the fabric of spacetime that it warped in the vicinity that is the cause of the effects in this case. And this is what Einstein;s General Relativity ultimately shows, and precisely what his 4-dimentional field equation describes.

And, that would show the surface of the Earth as an accelerated frame. It is this concept you fail to understand.

Just as I have been attempting to point out all along.

Fact 5. The earth is not getting bigger, (as you have already agree to). Therefore the surface of the earth cannot be accelerating outward to produce the effect of gravity.

The effect of gravity on planet earth is not due to the surface of the earth acceleration outward. The earth's surface is not exerting a force upon us due to it's accelerated motion. It's not moving at all.

What's really hilarious about your nonsense is the fact that no matter how many times I keep telling you the Earth is not expanding or exerting a force, you keep repeating it over an over again. Funny stuff, dude. It shows you have no clue in understanding the Equivalence Principle.

On the contrary, we are "falling". Our bodies are in a state of "free fall" at all times.

Odd, above you claimed our bodies are "stationary" - which is it, stationary or free fall?

And what this actually means is that our bodies are constantly being accelerated downward. In fact, you don't even need to be touching the surface of the earth in order to experience the effect of gravity.

That is the point of being in free fall, you cannot "experience" gravity because there are no forces acting upon you.

If you climb up a ladder and step off you'll accelerate downward. But at that point you aren't even touching the earth's surface, so the force of gravity on you cannot be due to the earth's surface pushing on you.

It is the same effect as the Earths surface accelerating upwards towards you as you are in free fall. That is the point entirely of the Equivalence Principle, which you fail to understand.

And remember the earth's surface is not moving. It's not coming up to meet you, you are necessarily moving downward to fall upon it. Therefore you are the one who is exerting a downward force onto the earth's surface, not the other way around.

Again, your failed understanding. We don't exert downward forces on the Earths surface. That is false. You would need to explain the source of that force, but you haven't in any way.

What does Einstein's field equation have to say about this? Well, Einstein's field equation shows that we exist in a non-uniform field of spacetime. The spacetime at your feet is distorted and warped and is different from the spacetime that exists at your head. Einstein's field equation also describes time as being part of this 4-dimensional field, and it shows that time is flowing by more slowly at your feet than it is at your head. If you have been spending most of your life standing up, then your head is actually older than your feet. A strange situation to be sure, but true none the less.

Those effects are infinitesimally small and insignificant, which I already showed with the GPS satellite example. Did you not read that?

That is your failed understanding of GR. Nowhere does anyone but yourself, as far as I know, believes in that crackpot theory.

Of course, your free to provide sources for your theory, if you can?

So the fabric of space is simply warped. And our constant acceleration toward the center of the earth is due to our bodies being accelerating downward. It's not due to the earth's surface accelerating upward to us. So ultimately we are exerting a downward force on planet earth, not the other way around.

Again, you fail to understand GR and are not thoroughly confused.

Let's recap here, first you say our bodies are "stationary", then you say they are in "free fall", a contradiction, now you say our bodies are exerting a force downward on the surface of the Earth. Hilarious. Totally confused.

That force is caused by the presence of the earth however.[/'quote]

Baloney, there are no such forces in GR.

Because if it wasn't for the presence of the earth the fabric of spacetime would not be warped.

Sorry, but curvature in GR is not a force.

So it is correct to say that the presence of the earth is the "cause" of this situation.

A fallacy based on false premise.

But still it is your body that is producing a downward force on the surface of the earth, not the other way around. And the reason your body is doing this is because it exists in a warped field of spacetime.

Existing in a gravitational field does not produce forces in free falling bodies. That is entirely wrong.

So if you want to give an "origin" (or cause) to the force that we exert against the surface of the earth, that origin would be the fact that we reside in a warped field of spacetime.

Complete garbage.

As far as the time flowing slower at your feet than at your head, this too should be completely obvious to you if you have any understanding of General Relativity at all.

I understand it completely, it is you who doesn't understand that the differences between ones head and ones feet is so small, it is hardly measurable, and has negligible effect on anything.

Please show citations regarding your theory.

Fact 6. Gravity causes time to dilate. Time flows slower in a gravitational field (i.e. A field of warped spacetime) than it does in a deep space far removed from any gravitational field (i.e. A uniform field of spacetime)

Yes, we can see this in GPS satellite systems. Do you even know what the numbers are for a satellite 20,000 km in orbit? I provided them.

With this realization you can also see that within a non-uniform (or warped) field of spacetime time flows more slowly at places that are more intensely warped relative to places that are not as warped. The gravity at your feet is stronger than the gravity at your head. In other words, spacetime is warped more at your feet than it is at your head. (assuming you're standing up of course) And it is this difference in this field of spacetime that causes your body to be accelerated downward.

The effects of this are irrelevant. Yet, it appears to be key in your theory. Hilarious.

Of course, this is not due solely to the time dilation. The space itself is also warped. But the dilation of time plays a role as well because space and time are intimately entwined as single fabric. You can't warp one without warping the other.

So there you go.

I'm not proposing any new or extraneous theories.

Everything I've described above is already well documented in Einstein's General Relativity and described mathematically by his spacetime field equation.

If you disagree with any of the facts I've listed above please let me know which ones you disagree with, and perhaps we can move forward from there.

You have provided the same confused nonsense as previous. You still fail to understand GR. I provided multiple sources showing that the surface of the Earth is indistinguishable from an accelerated frame, which is what the Equivalence Principle states and what you fail to understand, yet you completely ignore those in favor of your own failed understanding.

You also provided no sources to support your explanation. I can only assume you will never understand it. Oh well.
