Ok what happens to mass if you can bring it to a standstill in space?
we all see it on things like startrek where the captain says all stop but the question could we realy bring somthing to a stop in space and what would happen to it if we could?
time?
size?
weight?
As far as i know there is nothing static in space and we have not tried to do it with a space ship yet?
and if we cant i wonder how slow we could get something to move?

why not? if you could calculate the net of all the forces acting on you you could take measures to counteract them.

even with things like gravity which theoretically have infinite range (albeit tiny in magnitude), you could just apply an opposite force

The question then would be what would happen to it once it came to a stand still?
how fast would time be going for it because as things go slower there time speeds up.
there mass get less and so on.

motionless in relation to what?

What are you talking about? I think this is an example of a little bit of knowledge being a bad thing.

just mass with out speed

Explain?

I can't wait to see how this thread evolves, as i have no idea of this kind of stuff.

Interesting question, but i dont quite understand why anything should change just because it's standing still in space Oo

Yeah but in relation to what?

Speed is only measurable based on a reference point. Think about it this way. We would say a person standing still on earth is motionless, but in reality he is moving thousands of miles per hour because of the earths spin. And faster because of the earths orbit. And the solar system is moving too. And you can bet your ass our galaxy is spinning around or some crazy shit.

So show me a way to measure actual velocity (not in relation to another body) and I'll show you a nobel-prize winner.

You forget something. All atoms vibrate unless they are at absolute zero, a theoretical temperature. Therefore, You have another problem to overcome before motion is purely absent.
