The radar waves from the police "radar gun" reflected back to the gun by the moving car are slightly different in frequency from those originally emitted.

The observing of any modulation of the speed of light falsifies the theory of relativity notion that the speed of light is constant with respect to any observer.

There is no such thing as the "fabric of space."

What is the scientifically proven nature of space?

All motion is relative to other "frames of reference," other objects or observers.

A meaningless statement.
Your response suggests that you think the speed of light can't be referenced to anything but frames of reference.
That is nonsense.

E=MC^2 proves that light speed can be referenced to the amount of energy per unit matter.
For, since it is known that matter can't be created nor destroyed, all loss of energy must equate to a decrease in the speed of light.

Really?? This information would be AMAZING to all those physics and engineers that rely on the predictions made the General relativity based on the speed of light. Would you care to back up your assertion with peer reviewed articles, or show a text book used at a major university that shows that to be true?

It looks to me that I have two choices. One, I can throw out my GPS, because without light being a constant, and GR making accurate predictions, it can't possibly work, or I can accept the assertions of an anonymous person on the internet that makes a claim without backing it up.

I think I will keep on using my GPS.

If you have no understanding of this subject that is not my problem.

GPS doesn't require magical theory.

GPS doesn't require magical theory.

Then, you will be able to, you know, support your claim.

Please do.


And, no, GPS doesn't require magical theory. It requires that the predictions of General relativity be correct, and that the speed of light is constant. That's not magic, that is observation.

Time and Frequency Measurements
Using the Global Positioning System

This paper describes how Global Positioning System (GPS) satellite signals are used in time and frequency metrology. It discusses how a GPS receiver can provide a reference signal for frequency calibrations and time synchronization. It also explains the several types of time and frequency measurements that utilize GPS signals. These include one-way or direct reception measurements, single and multi-channel commonview measurements, and carrier phase measurements. A discussion of how GPS signals can provide traceability to national and international standards is also provided.

The basic carrier-phase equation (Equation 1) shows
the parameters that must be determined in the analysis.
The analysis software makes it possible to make a good
estimate of most parameters. Generally, the number of
cycle slips and the atmospheric delays are the most
difficult parameters to determine.

R
S = g + cS - cR+ trop - ion + mult + cp + NR
S(1)
where,
= carrier wavelength, c/f, R
S = carrier phase observable for satellite S and receiver R,
g = geometric range, √((XS-XR)2+(YS-YR)2 +(ZS-ZR)2,
S = satellite clock error
R = receiver clock error
trop = propagation delay due to troposphere,
ion = propagation delay due to ionosphere,
mult = multipath error,
cp =unmodelled errors and receiver noise,
NR
S= carrier phase ambiguity or bias.

The above shows that no magic corrections are required for GPS to function, and that GPS requires reference to real and palpable national standards rather than to imaginary concerns.

The above formula is for the carrier-phase GPS that is accurate to a millimeter. That is the precision form of GPS.
Whereas the common GPS is accurate <10 meters and is the Course Acquisition GPS.

The variable symbols didn't translate symbolically to this post format..
However, the description of each variable clearly what natural parameters are required.
Whether you can find this paper on the internet I don't know.

And, no, GPS doesn't require magical theory. It requires that the predictions of General relativity be correct, and that the speed of light is constant. That's not magic, that is observation.

consideration of all light speed measurements over the last hundred plus years prove that the speed of light is decreasing contrary to theoretical notions of nature.

[Joman]

Look folks, any one can google and regurgitate theoretical claims being made in disregard of up to date experiments. The idea that relativity concords with experiments is a hoax. Only non scientific minds fall for magic explanations.

It's time to wake up and give up the naivette of them that believe whatever thing they are told without one shred of critical thinking involved.

There is no scientific evidence of.....

constant speed of light,
increase of mass with speed,
singularities,
black holes,
dark matter,
dark energy,
nature creating itself,
nature designing itself,
science of chance based trends,
nature clocks running backwards
relative truths.

Each of the above are born of magic related imaginations looking for excuses for nature not agreeing with the bias' of theorists.

And yes, common sense is all that is needed to prove false sciences are false.

I already proved that the formula run by GPS system doesn't include any relativity whatsoever in the real world.

And you have not presented diddly.

let me quote the relavent phrase.

o achieve this level of precision, the clock ticks from the GPS satellites must be known to an accuracy of 20-30 nanoseconds. However, because the satellites are constantly moving relative to observers on the Earth, effects predicted by the Special and General theories of Relativity must be taken into account to achieve the desired 20-30 nanosecond accuracy.

Because an observer on the ground sees the satellites in motion relative to them, Special Relativity predicts that we should see their clocks ticking more slowly (see the Special Relativity lecture). Special Relativity predicts that the on-board atomic clocks on the satellites should fall behind clocks on the ground by about 7 microseconds per day because of the slower ticking rate due to the time dilation effect of their relative motion.

Further, the satellites are in orbits high above the Earth, where the curvature of spacetime due to the Earth's mass is less than it is at the Earth's surface. A prediction of General Relativity is that clocks closer to a massive object will seem to tick more slowly than those located further away (see the Black Holes lecture). As such, when viewed from the surface of the Earth, the clocks on the satellites appear to be ticking faster than identical clocks on the ground. A calculation using General Relativity predicts that the clocks in each GPS satellite should get ahead of ground-based clocks by 45 microseconds per day.

The combination of these two relativitic effects means that the clocks on-board each satellite should tick faster than identical clocks on the ground by about 38 microseconds per day (45-7=38)! This sounds small, but the high-precision required of the GPS system requires nanosecond accuracy, and 38 microseconds is 38,000 nanoseconds. If these effects were not properly taken into account, a navigational fix based on the GPS constellation would be false after only 2 minutes, and errors in global positions would continue to accumulate at a rate of about 10 kilometers each day! The whole system would be utterly worthless for navigation in a very short time. This kind of accumulated error is akin to measuring my location while standing on my front porch in Columbus, Ohio one day, and then making the same measurement a week later and having my GPS receiver tell me that my porch and I are currently about 5000 meters in the air somewhere over Detroit.

The engineers who designed the GPS system included these relativistic effects when they designed and deployed the system. For example, to counteract the General Relativistic effect once on orbit, they slowed down the ticking frequency of the atomic clocks before they were launched so that once they were in their proper orbit stations their clocks would appear to tick at the correct rate as compared to the reference atomic clocks at the GPS ground stations. Further, each GPS receiver has built into it a microcomputer that (among other things) performs the necessary relativistic calculations when determining the user's location.
