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 space there is no gravity
This might be where you’re tripping up. I don’t know where you got the idea that there is no gravity in space…there is gravity EVERYWHERE. All matter exhibits gravity on everything. You’re being pulled toward Saturn, and Andromeda, and quasars billions of light-years away, and even toward me. You don’t notice it because the Earth’s gravity is much, much stronger.
