All changes in velocity are either acceleration of the observers and/or acceleration of that which they observe |
Accelerated free falling observers will see the ground accelerating
upward toward them; while observers on the ground will see the free
fall as increases in the velocity of what they observe free falling
toward them.
That's what relativity's all about.

But what if there are NO observers? What happens then?

Then it becomes a philosophical question. The physics, however, stay the
same. Now the other deal is what happens if there are two observers in
different locations. One could handwave a few paradoxes over which way who
is falling.

Simple; we just wait a few million years until some observers evolve.

That's what Donald's relatives want to know.

What about accelerated free falling observers on the ground?
Or accelerated free rising observers?
Or accelerated free falling poeple who aren't looking at the ground?
Or free falling ground that is accelerating at an observer?
Or the void between your ears?
Surely (and I'll call you Shirley whenever I want.) relativity
is about those things too?

Why don't you remove the alt.sci.physics from your target forums.
You're always carrying along huge threads that are dumped
into this newsgroup daily.
Is it so bad to just satisfy sci.physics Rambos' thirst?

It's even simpler when you do what Shead does, and cancel the d's :)

Wow.
You powerful stupid, and double-plus rude to boot, and mentally sick as
