"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.


“I am only an egg.”

Decomposed > He thinks that when everything is sufficiently spread apart, matter evaporates and the universe's state is identical to its state prior to the Big Bang.


If all the matter 'evaporates' . . .
Then where does the matter which apparently spontaneously comes into existence come from?

How about this. The Universe is infinite. Meaning there will be an infinite number of 'Big Bangs' and 'Big Crunches'. Each of the 'Big Crunches' will collect matter from 'neighboring' Big Bangs till it has enough to 'Big Bang' itself. Which in turn feeds the fodder to fuel the next big crunch(es).

With hundreds of Billions of years between the Bangs.
