Dear PF Forum,
I just want to ask a simple question.
Even if we are at rest (ignoring that the Earth rotates, evolves around the sun, orbitting SMBH and Milky way orbitting what? Virgo Supercluster? And Virgo Supercluster to what?),
A. So even if we are at "rest" (blue line), are we always moving just like in ST diagram? We move trough time.
B. And gravity curves what? Space? Time? Space Time? And we are forced to move (green line), so that ##t_{green}^2-x_{green}^2 = t_{blue}^2##?
If we see the ST diagram, I think gravity just bends time not space. But what I ask, if we are FORCED to move.
