Fiz > Inertia is the cumulative gravity in the universe acting on a point.


Oh really, Fiz?
Care to try to explain to me just how the gravity over in the Andromeda Galaxy is supposed to affect that Big Old rock I'm trying to move?

In the meantime :
>>>
inertia
noun
1. The tendency of a body at rest to remain at rest or of a body in straight line motion to stay in motion in a straight line unless acted on by an outside force; the resistance of a body to changes in momentum.

2. Resistance or disinclination to motion, action, or change.
>>>

The above definition of inertia was figured out a long long time ago. And, that definition underpins a LOT of the engineering techniques and technologies used over centuries.

"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.
