Time and 3 dimensional space form 3+1 dimensions. I understand this i.e. given time and 3 dimension space coordinates you can locate anything including OBL.
But what does physics mean when it says gravity is the curvature of space-time. Can anyone picture and explain what they are on about. I keep thinking of a folded sheet of paper..I dont know why.
Why am I asking this you may wonder but I saw a documentary on the history of the study of the extent of the Universe last night.
