- Further details on what ST curvature really means
Here's what I read in a closed thread asking about the meaning of spacetime curvature:
So does that mean if we were able to move to some spot "way above the earth/sun/distant galaxy" where we could watch light and trace it from a distant galaxy (which is otherwise hidden from us) pass around (?) the sun and hit our telescope, it wouldn't literally curve around the sun as is depicted in so many laymen's physics books? (I'm describing the Eddington experiment of course.)The curvature of space-time is a mathematical curvature, and should not be taken to mean that space and time are somehow curved through each other or through some as yet undiscovered dimension in the way a two dimensional space can be curved into the third dimension in a three-dimensional world.
