Newton's explanations ruled . . . until a guy named Einstein upended them.

Actually, Newton's work was known to be wrong long before Einstein, but nobody knew why. Today, Newton's discoveries are usually good enough for engineers. You have to be dealing with really big numbers before their shortcomings much matter.

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.
