This video was talking about what space-time means for gravity.First,acceleration was mentioned.If you add gravity,The speed of the things in space-time will be faster. Second,The movie discuss how to make up the space-time.There must have a lot of patches of space time transformed by different amounts.When fragments was assemble like a quilt,space-time has shaped. When we are discuss space-time,we must think of Einstein.He can describe precisely how each patch is stretched and squashed according to nearby mass and energy.He found that the presence of stuff curves the space-time,and curving space-time moves the stuff around.This is gravity and space-time that Einstein explained.
