Reply to comment by TheMan5991 in eli5: back then, before astronouts goes to space, how do we know about thing like nonexistent of oxygen & zero gravity? by zetasstra
This is an interesting statement. Is there no place in the universe so distant from any large mass that 0 gravity or negligible gravity could be attained?
Force of gravity drops exponentially with distance so I feel like this is very possible.
Edit: after a little googling and finding out the shockingly huge mass of stars like our sun. I believe finding a spot in space with negligible gravity may be harder than I thought.
Lagrange points are cool in that the gravity force of two masses cancel out there, but it's really no different than how orbiting causes 0 g's even though gravity is still present

Yeah my first thought was Lagrange points are probably the closest thing to what you're describing.

If we were not orbiting the sun and were directly feeling it’s gravity, it would be about 1600 times weaker the gravity we feel on earth.
I don’t know how weak gravity has to be before you feel “weightless”, though. That’s a good question.
