Errr, at least get the history on Einstein accurate.
I'd be glad to if you would kindly point out an error that I've made thus far.

GR
What thought experiment are you talking about? Can you name this?
There were many, but probably the most historically famous is the thought experiment of being in an elevator in outer space far away from any gravitational field versus standing on the surface of earth.
This was an experiment that could not be done in Einstein's days. Yet he performed this experiment in his mind and realized the principle of equivalency which is at the heart of GR. It states that there is no measurable difference between accelerating though a totally uniform field of space devoid of any gravity at all, versus standing in a gravitational field on Earth.
Note:
There actually is an experimentally verifiable difference between these two situations. However this difference turned out to be unimportant. Moreover, Einstein himself could have recognized even this difference without an actual experiment if he had simply given more complete thought to his thought experiment. In fact, this measurable difference would have actually been even further insight to support Einsteins epiphany.
So there you go. You asked for a thought experiment I gave you one. There were actually many others. Einstein was very BIG on thought experiments. In fact, the entire debate between Einstein and Bohr consisted entirely of thought experiments. Einstein offered the thought experiment, and Bohr offered a thought solution. No actual physical experiment ever needed to be done to settle their debates. At least not until the EPR proposal. But even then John Stewart Bell solved that with pure mathematics (i.e. pure thought) before it was confirmed in the lab physically.
So most of science is done as thought experiments.

You are now trying to argue that when people come up with a hypothesis (answer to a questions because there is evidence) and the hypothesis turns out accurate (AFTER falsification/observation/tests), then it was based on a thought experiment. That is just ignorance of the scientific method.
That is indeed historically true all through science. Galileo hypothesized that all objects would fall at the same rate of acceleration if air resistance could be ignored. It turned out that he was right. So Galileo arrived at his conclusion via a pure thought experiment.
JohnA wrote:
You are also confusing though experiments with practical analogies. There were practical experiments that could be run to verify (falsification concept was not adhered to then) his theory. And these experiments were done, and is still being done today!!!!!!
They weren't done right away. It took quite a while before Einsteins hypotheses could be experimentally verified. Yet that didn't stop Einstein from moving forward with confidence that his thought experiments alone were producing USEFUL results. Not necessarily verified FACTS. I never claimed that they would be verified facts.
JohnA wrote:
Not to mention that Einstein's GR is INCOMPLETE. It does not have an answer for gravity, not a complete one.
That's totally irrelevant. It's clearly true within a very large range of conditions. A far larger range than Newtons Gravity works. Yet Newton was considered to be doing "science" too. In fact, Newton was guessing that gravity could reach out to the planets. That had to be a "Thought Experiment" for Newton because he had no physical way of testing that hypothesis.
So Newton also did science by thought experiment. And Newton's science has been the PILLAR of science for centuries now. We even still use it today and simply recognize that it too is incomplete and only holds in restricted situations.

You are comparing apples with pears when you try and compare your Einstein ignorance with your wishful thinking.
I'm not ignorant of Einstein. You have no justification for that groundless accusation.
JohnA wrote:
GR vs QM: Einstein lost. He said his god does not play dice and Bohr told Einstein to stop telling his god what to do. So Einsteins "glove" analogy / though experiment was wrong. And empirical testing showed it wrong, not philosophical antiquity based on the dark-ages.
So? Where did I ever say that ALL thought experiments must be true?
I never made any such claim.
JohnA wrote:
Btw, if Einstein had FAITH, then no-one would even have been able to find evidence for his GR. Faith is an admittance that there is no evidence.
He clearly had FAITH in his own ability to reason through thought experiments. Possible more faith than warranted, but he clearly had faith.
You just pointed out a thought experiment where Einstein was wrong. But obviously he had some level of faith in his reasoning to suggest his glove analogy.
Or do you think that Einstein was just guessing at everything? If that were true he would be the LUCKIEST guesser in history to have guess at Special Relativity and again at General Relativity.

This is what this wishful thinking do to one, it covers your filter of reasoning resulting in irrational beliefs.
You are going way off a totally unwarranted deep end John. Where have I ever claimed to "believe" in anything?
I conclude that the Eastern Mystics have the best rational explanation for human experience. And I make that conclusion based entirely on reason. A present there is no experiment that can be done to prove them wrong. And all the evidence that science has discovered thus far supports their claims.

Moreover, as I had stated in my post, we don't even need the concept of sci-fi teleportation systems.
Am glad you admit that this wishful "though experiment" is just that, pointless. Especially when you trying to solve a completely unrelated problem.
I never did need the sci-fi aspect of it. And I pointed that out in my first post on this particular issue.

And then you dig right back into this wishful thinking:
All we need to do is black out, or go unconscious and return to consciousness again, and we've done the same thing. We can then ask whether it's the same YOU?
And your answer is?
I don't see you offering a scientific answer here.
JohnA wrote:
You just don't understand their answer. Because if you did you would see why they are right.
You are right, I do not rely on wishful thinking. I do not explain a scientific "problem" (consciousness) by using another sci-fi "wish" (teleportation). This is faulty reasoning, moreover just wishful thinking. Some say that is how some of the modern religious were born: pseudo-con man selling to the sci-fi fool.
And now you are creating totally false strawman claims.
There is nothing "Wishful" in anything I propose. I couldn't care less whether reality is secular or mystical. I'm totally open to whatever reality has to offer. If I die when I die that's fine with me. I'll never even know that I had died. Neither will I ever know that I had ever lived at that point. At that point in time I may as well have never existed.
It's certainly not that I don't want secularism to be true, but surely even you can see how utterly uninteresting such a reality would be. If that's the truth of reality then what's to discuss? May as well just wait until you die and it will all be over. And at that point there would have never been any reason to have ever lived.
That may very well be reality John. But we certainly don't know this to be the case, so why would anyone waste their time pushing for that conclusion?
Where is your scientific evidence that this conclusion has any validity?
And be careful because after our conversation thus far I can easily point out that your theory is indeed "Incomplete".
The mystics have a very sound philosophy which may very well be true. And every bit of scientific knowledge to date is in total agreement with their philosophy. So I have no idea why you are even complaining about it. They may be onto something truly wonderful.
Why are you so anxious to knock it?
