Relativity

If there are two objects in space, one next to another and one of them is accelerating to the speed of light, the time will slow down for it. So when it will return, if we had two atomic clocks synched, i would see that one object had its time slowed by the acceleration.

So technically if we take space. Planets, stars, rubble moves across the universe. We dont know who relative to whom, we dont know who is the fastest because all is relative.

So if i had atomic clocks across the debris of space, i could tell which is moving the fastest (the one who's clock is the slowest). Our planet is revolving, it spins around our sun, the sun is moving around the galaxy, the galaxy is moving around who knows what, there is velocity in the universe that's for sure.

But if we had atomic clocks across all debris, we could tell, which object is ACTUALLY standing still.

And if we do, how fast could time fly on that object? How fast are we really going on this speck of dust? Or better asked how slow is our time really? Could being absolute still in the universe by some sort of a time singularity where time flies so fast, its all in a single instance? Is velocity the source of existence?
