Is time slower in space?

Let me add to my question...If I was to go to the Int'l space station, would I age slower than someone on earth...or if I was to bring a watch up into space, would it still keep time at the same pace as a watch on earth?

Where in space? If you mean somewhere in our solar system, I'm guessing it's about the same. Of course, I'm a high school student with no background knowledge at all.

Near massive objects (black holes, for ex.), yeah time will appear slower from a person looking from FAR AWAY ONLY. (relativity).

Technically, time is never slower or faster. It's all relative to the viewer. You can generalize slow time if you mean the viewer is sitting on earth looking out into space.

Compared to what? And slower to whom-- an outside observer? Or an inside participant? If Einstein taught us anything, it's that measurements are meaningless without a frame of reference.

So to answer your question, it's a definite yes and no.

yep.

Time is a constant in the fabric of space, but can appear as a variable due to the behavior of light around large gravity wells. Since light is kind of our benchmark of time (since we really have no understanding of any other dimensions, such as a possible 4th dimension, aka the dimension of time), time can thus appear as a variable when large gravity fields affect the travel of light.

time is slower when you're moving such as if you were traveling near warp speed or the speed of light.

Wasn't this the original question?

Wat.

It definitly is slower in space, not just relative.

If you went into space for 40 years when you got back to earth you would not look 40 years older. Not by much but you wouldn't have aged as much.

well time gets slower as you speed up. experiments have proven this with two identical very accurate clocks. one was flown to the ISS and the second was kept on earth. When the clock from the ISS came back, it was slower then the clock that stayed on earth.

besides, time is relative. it's a human invention. can you really define time?

I know some people have already said this but here's the bottom line:

the difference in time between two reference frames changes depending on
1) how fast one is moving compared to the other (special relativity)
2) how close one is to a object of large mass (a planet) compared to the other (general relativity)

Let's use Louis Lane and Superman for examples. Louis Lane is on the surface of our planet and Superman is hanging out above the Earth in some sort of orbit that makes him float above her. They sync their clocks. Louis Lane thinks Superman's watch is running fast and Superman thinks Louis Lane's watch is slow. This shows that time "slows" the stronger one's gravitational field is. (stuff about black holes and the Schwarzschild radius goes here).

Now, to show Special Relativity. Let's have Louis Lane on the top of some very tall mountain and Superman is about at the same height but now is for some reason flying around the Earth really fast in a failed attempt to turn back time. Now, Louis Lane thinks Superman's clock is running slow and Superman thinks Louis Lane's clock is running fast.
