If we take the math strictly at face value, which means ruthlessly resisting the temptation to indulge even very plausible...

You have a calculated a quantity that has the dimensions of distance over time, and you can interpret it as a speed (it's an...

Seen in terms of geometry, it is closely analogous to two cars driving at equal speeds ##v## down straight roads that make an angle...

I think it helps to suspend your disbelief for as long as it takes you to learn how it works. Putting your mental energy into arguments...

You have overlooked the relatively of simultaneity. Say that observer A is located on earth, B on the ship, and both agree that the...

No position means no path along which we can integrate to find the proper time. Instead we use QFT and calculate an amplitude for a...

I think you misread what I said.

I am sorry, but Grok has lied to you. The forum rules specifically do not allow posting any theory that has not already been published...

To understand the rotating disk in special relativity, I believe you need some background material that is not high school level. The...

How should the Lorentz factor be applied to motion that is not classical? We don’t. Proper time is the length of a path through...

Is the question "is simultaneity still relative in a universe with a CMB that provides a global clock"? If so, yes it's still relative...

In general, no. We can choose any coordinate system we please according to whatever amuses us, and there's no reason that the...

That’s how the math tells you that you’re misapplying it. The formula is only valid for ##v\lt c##.

To quote Einstein: Time is what a clock measures. At first glance this statement appears to be no more than a clever sound bite…. But...

Something I didn't learn in school (or maybe just misremembered) is that Magellan did not return to Spain, he was killed in the...
