Mars Disco Posted May 21, 2021 Report Share Posted May 21, 2021 (edited) A classic physics experiment is to drop a feather and a bowling ball inside a vacuum to show that they both fall at the same rate. The common misconception is that there is no gravity in space, but NASA and other educators are trying to dispell that notion by calling it microgravity. In reality, the reason anything can stay in orbit is gravity. When you are in orbit, you are constantly falling, the only difference is that you are going sideways fast enough to miss the ground. Since you are always in free fall, all of the forces ballance out which creates the sensation of floating. You can create a similar effect inside the atmosphere by flying on a parabolic trajectory in a standard aircraft (look up "Vomit Comet") Edited May 21, 2021 by Mars Disco 1 Quote Link to comment Share on other sites More sharing options...
AquaRegia Posted June 29, 2021 Report Share Posted June 29, 2021 Perhaps the OP was envisioning a TRUE vacuum: a universe completely empty of matter. In that case, with no mass to produce spacetime curvature, there truly would be no gravity. Of course, there would also be no inhabitants to experience this lack of gravity. 0 Quote Link to comment Share on other sites More sharing options...
