"Space-time tells matter how to move; matter tells space-time how to curve." - John Archibald Wheeler #space #spacetime #curves

Inertia is the cumulative gravity in the universe acting on a point. Gravity is the result of mass bending spacetime. Space is CREATED by gravity; if no gravity then no space.

Therefore, if the universe was infinite, inertia would be infinite...and nothing could overcome inertia...and nothing could move.

ipso facto, the universe is not infinite.

Following this line of logic, if all the mass in the universe disappeared, all the space, and all the gravity, and all the inertia would disappear. At the speed of light, of course. How could you move if there was no longer any space in which to move?


I'm about 99.9% I've got all that right. I am sure about the quote at the top, and Wheeler would know.
