Title: What effect would zero gravity have on space?
Post by: EvaH on 26/11/2018 14:19:09
Daniel wants to know:

We all know about absolute zero temperature and the weird effects that those temperatures have on matter (even though you can never quite get to absolute zero). What about absolute zero gravity, does it exist? And what effect would that have on space? 

What do you think?

What effect on space?  There would be no energy or matter, and thus no real space at all.  If there was any 'stuff', it would have gravity.  It isn't something that can be lowered like temperature.  There is nowhere, even in the furthest reaches between galactic superclusters that is free of the negative gravitational potential of the matter all around it.

Gravity is a property of SpaceTime.
taken as a force it may disappear
But it's there

When you're 'weightless' it's not there anymore
Observer dependent
