People often illustrate space-time curvature with an heavy ball curving a sheet but the heavy ball is curving the sheet because that heavy ball is pulled by Earth’s gravity but in space there is no gravity without space time bending,so while there is no gravity how is the space-time bent wherever there is mass?
In: Physics
That’s what gravity is in general relativity. That curvature of space-time is gravity. Space-time tells matter how to move and matter tells space-time how to curve.
