I thought the test was cute, Alexandre.

And I fully understand what you are trying to do with your book, but I cannot take the first hurdle.

As I see it, Spacetime is the wrong word for Einstein's framework. I see it as the measure tape that correctly measures things. Despite the good results, Spacetime is itself not involved with the measured results.

But I can say it differently as well. The scientific community created an inverse where it is not allowed to do that. A theory is never a fact, no matter how well the theory seems to fit the facts.

In science, we must start out with the evidence and from the evidence we can build theories. That is science.

Never, ever, can science take a theory and make it the foundation of science.

That is where many physicists are making their mistake: they are wagging the dog.

In other words, it is fine for religion to be top-down, but science must always be bottom-up. One cannot declare Spacetime an absolute foundation. It is not the correct scientific approach.

When we then review time dilation, we can conclude that it was matter that 'dilated'. Matter got warped in behavior due to its placement in a different spatial position. The clock just showed that different behavior. Matter changed, time did not.
