If you're speaking of time and space, no, they're different -- they're certainly all part of one spacetime, but they're distinct. This distinct:
t' = t √(1-v^2/c^2)
t = time
v = velocity
c = speed of light
t' = time at velocity v relative to velocity 0
Put into words, this special relativity relationship shows that an increase in velocity (movement in space) causes a reduction in time's rate of passing (movement in time). The general relativity version has more terms, and shows a relationship between mass and both space and time.
So space, time and mass aren't the same thing, but they're part of an interrelated system, one easily described mathematically.
> Time runs slower for us here inside the gravity well of Earth than it does for astronauts in zero gravity.
Yes, true, but astronauts in orbit aren't in zero gravity, they're in free-fall. The gravitational force at typical orbital heights is nearly as strong as it is at the surface.
