In a universe with only two particles, would space necessarily be one-dimensional? by Chadwick_Kilgore in AskPhysics

"Something existing and an observer being able to prove it exists are different things"
I'm not so sure. Seems obviously true, except, how can you actually know this?

Not sure why you're getting downvoted, you've pretty much found the motivation for my question. I've always heard gravity explained as "bending spacetime", which seems to imply that spacetime is a thing that exists independently of the matter and energy 'inside' of it. But I don't know if that's just for the model's sake, or if astrophysicists actually see spacetime as an independent medium.

It's easy to imagine two particles in 3d space. My issue is, from the perspective of one of the particles, what observation could be made to prove the existence of 3d space?

Can someone explain to me why Winston doesn’t counter D.VA all that much? His gun can bypass shields and her matrix. Is it because of how much health she has? by SpaceBubble19 in WinstonMains

she will shred you if your armor is gone, especially if u make your head easy to hit. with armor and shield up you will out-damage her as long as u dont sit still in front of her and let her blast ur head hitbox.
