Are there places that defy law of gravity?

Answer 1

Not really.

So far, everything humans has found is affected by gravity, and reacts to it in

fairly well understood ways.

Gravity is basically about how objects with mass pulls on each other. It's a force

that's dependent on the product of the masses involved, and the distance

between them.

Humans pull on Earth the same way as Earth pulls on humans.

If you're in space, you're a far, far away from anything heavy. The situation

has nothing to do with defying gravity, but due to the distances involved, we

don't notice it that much. But it's still there, doing its thing, entirely according

to the textbook.

Then there is the Zero-G flight, but that's not about defying gravity either.

Rather about understanding it, using it and countering it to create free-fall

conditions. And while seemingly very similar, free-fall and zero gravity aren't

the same thing.

By having a plane follow the same trajectory and speed as - say a thrown stone -

everything within the plane becomes weightless WRT the plane, for the descent

part of the trajectory, for about 20 seconds.

Apart from the plane being able to land, it's like being inside a falling elevator.

If you and the elevator are both falling at the same rate, there's no longer any

force pushing you against the floor.

Zero gravity is hard, and not really found anywhere inside out solar system.

Zero gravity means there's no force acting on you at all. Free fall is a lot easier,

and simply means that you and your immediate surroundings are free to react

the same way to the pull of gravity.

Answer 2

Empty space by it self dose not have gravity. Gravity related to a massive object example our moon & earth. In space you may sense the gravity which comes from one of the massive object in space.
