Question: is there a way to turn off gravity in your own home?

Steven Gardner answered on 24 Jun 2013:

Yes there is, but you’d have to launch you home into space and put it in orbit around the earth. Or alternatively you could drop it from a height and then you’ll have no gravity for a few seconds (before you crash, obviously!)

Zero gravity isn’t really no gravity. What it is in fact is a constant freefall, when astronauts are in orbit they are actually falling towards the earth, the reason they don’t crash is that they are moving so fast in the direction at a right angle to the surface that the surface falls away from them at the same rate.

It’s quite hard to explain without a diagram so here’s one so you see what I mean.
