Could gravity be the result of space trying to deflate/return to the pre-Big Bang singularity, kind of like pulling magnets apart? i.e. is gravity the “opposite” of, or a reaction to, “space?”
I may be off the mark with what you believe, but just in case:
It's a common misconception that the big bang originated at a specific point. The big bang seems to have happened everywhere simultaneously, so it wouldn't be true to say that gravity is pulling everything back toward a point of origin.
Here's an excellent video on misconceptions about the universe: https://www.youtube.com/watch?v=XBr4GkRnY04 https://www.youtube.com/watch?v=XBr4GkRnY04
(Ironically, the video was created because the creator was a scientist, yet they fell into the trap of believing something incorrect to the point of being publicly mistaken about it. The universe is extremely counterintuitive!)
- jsmthrowaway 9y agoHoly shit, the Big Bang happened everywhere simultaneously because the Big Bang brought quantum fields into existence. Wow. I get it now. As a non-physicist, wording it like that made a lot that I didn't understand suddenly click.
- andyjohnson0 9y ago> the Big Bang happened everywhere simultaneously Until the big bang happened there wasn't any "where" for anything to happen in
- jdkuuuu 9y agoThis really makes it sound like a simulation

- monort 9y agoThis only applies if the universe is infinite. We don't know it for sure, though we have a lower bound of the universe size at 250 Hubble volumes: http://onlinelibrary.wiley.com/doi/10.1111/j.1745-3933.2011.01040.x/abstract http://onlinelibrary.wiley.com/doi/10.1111/j.1745-3933.2011.... And infinite universe brings strange phenomenons, like our doppelgangers far away, that are exactly like us.
- hau 9y agoInfinite universe can contain infinite set of objects without any of them being your doppleganger. Unless there's only limited set of objects that can exist in universe at all which doesn't seem likely.
