How far off are we really from achieving artificial gravity?
gpt
Well, we can simulate gravity reasonably well by spinning something at a constant velocity so that the centripetal acceleration is close to 1g., we just haven't been able to put anything big enough to do comfortably it into orbit. Or, if we had something that constantly accelerating at 1g, that would do it too.

As for artificial gravity like in movies, where everyone is floating around and someone presses a button and the 'artificial gravity' turns on and everybody falls to the floor? That's not really possible.
