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
Mass bending space time IS what gravity is. The example show with a ball on the sheet represents that phenomena in a method that humans can visualize.
