If you were the only object in space and you were not moving would you feel time (also spacetime is not moving either)?

spacetime $\ne$ aether

If you were the only object, there would be no way to make any measurements. You would continue to exist is spacetime.

Certainly, you can still count and you would still age...

single observer

Has this "only object" a wrist watch?

Well what i was getting at if you could get your speed to zero while time was not moving would you not progress in time. And we know that if go the speed of light then time would stop so i was just trying to find another way time would stop.

That really doesn't make a whole lot of sense, but yes, if you could stop time, time would stop (). And your speed with respect to yourself and light is always zero. So in the context of your original post, you are always stationary.

Yes, you would observe the passing of time, or as you would say "feel time."

I think the best answer is that you would indeed suffer while you suffocated from no air to breathe - but probably not for very long. (Just what one would expect from a sudden vacuum exposure).

If you assume that you had air to breathe, water to drink, food to eat, and some sort of system to recylce them, you'd hardly be "the only object in space".

If you were the only object in the universe, the idea of motion makes no sense. Motion is relative.

Right. It doesn't matter anyway. Relativity always happens to other people, not oneself. That's where the name comes from: it deals with relations, not physical changes caused by absolute velocities.

In fact the observer himself will never detect any changes in the flow of time if he checks his clock, in principle that is. Living in deep space for a while may mess with your observations.

Greetings, Pete. Yes, and the idea of 'one thing' is also problematical. When is a thing one thing, as opposed to several things stuck together ? The OPs question as posed is devoid of physical meaning. That means it must be philosophy so I'm out of here.

You'll definately need the winter underwear.
