That isn't determined by looking at equations. That's determined by

becomes important, Bobby.

Now, you can say, "But the problem is you're trying to stick in
*measured* quantities in for t and t'. The equation is right but t'
isn't what you measure. What you measure is some other number."
That's
fine if you want to invent comic-book heroes and other mythological
things, but it's not physics.

Well, yes, it is physics, PD. I even got one scientist to show with
the Lorentz equations that t'=t for this particular problem. He had
to flip frames of reference to do it, but that is standard procedure
with the Lorentz equations.
At any rate, there is no doubt in physics that Galileo was right
about the principle of equivalence.

About the principle of relativity, yes. The principle of equivalence
means something else.

I thought you scientists said Galileo was wrong about relativity.

No,
YES!
