I hear a term being thrown around that I don't fully understand called the fabric of space-time. For example when giving an explanation of gravitation it is said that this is caused by the curvature of space-time and that gravitation is the acceleration on a body by way of it falling into something with mass, given that mass tends to curve, or warp this fabric of space.
My question is, what exactly is this 'fabric' we call spacetime? Isn't space supposedly empty? Isn't it near close to a perfect vacuum? If it is empty, what then is the fabric of space? Thanks for taking the time to answer this question.
Edited by Adminnemooseus, : Changed topic title from "A question about space-time" to "What is "the fabric" of space-time?". Also changed a couple of "spacetime" to "space-time" while I was at it.
Edited by Adminnemooseus, : Remember to actually make topic title change.
