Theoretical physics has locked itself into a corner of not making sense.

Einstein made a huge mistake by promoting the idea that time changes for everything differently, depending on time and space.
This means that even within one thing the time can be different between the front and back of the same thing, causing so many paradoxes.

Einstein also got rid of the basic concepts of global time and global space, which are essential part of the physical world that we see and experience.

What a smart person should have done...
,,is change the idea of relative time with a simple local clock.
The clock-speed defines the speed at which physical forces are experienced.
So if you go fast, the clock goes slower. And the physical forces are experienced slower, making them weaker.
And the clocks do not need to be in sync, because they are not real time.

No mythical time-travel stuff, with exact the same formulas.
Just plain simple.

But why did they promote this time concept, confusing the hell out of everyone?
-> Because they never understood it themselves.

Einstein's physics theories predict time dilation, which is pretty much what you described. Not time travel as we think of it, and certainly not into the past. That would only be possible with a wormhole.

Time dilation has been proven, both with experiments on earth and by observing massive objects such as black holes.

Yep.

You have to use it for GPS. The time measurement has to be so precise, that if you don't account for relativistic time dilation from the GPS satellite being in a weaker gravitational field, you get your position wrong.

And without it, you can't explain the advance of Mercury's orbit.

The GPS and Mercury orbit is related to Einstein's gravity. A different Einstein theory: General relativity.
Which he derived from Special relativity, which deals with the speed of light and time.

The first gravity theory of Einstein was about a variable speed of light.
You can get the same GPS and Mercury orbit with it.
And according to RonHatch it is even better, but we never see it discussed.

Not quite true. The derivation was independent from special rel.

The first gravity theory of Einstein was about a variable speed of light.

Really?

Contradicting Maxwell's equations?

When was his work on this theory published?
