Gravitational Attraction of Motionless Masses

Click For Summary
In a hypothetical universe with only two motionless masses, the discussion centers on whether these masses would begin to move toward each other due to gravitational attraction. Some argue that without time, no motion can occur, making the concept of distance between them meaningless. Others counter that while the masses may not perceive motion, they would experience changing gravitational forces, allowing for measurable acceleration. The analogy of an elevator in free fall illustrates that while constant acceleration may feel inertial, changing acceleration can be detected through various means. Ultimately, the debate highlights the complexities of measuring motion and forces in a theoretical framework devoid of time.

The OP described a universe with only space and two masses but it seems that people have been adding to this universe.Where, for example, did the observers come from?
He did not mention any commentators either.
Maybe I should shut up.:smile:

Maybe the two masses are those of the observer...

hello everyone i am new to this website and forum.But i have been really good at physics this topic gravity has become quite appaling sometime now.However i believe Einstein theory to be wrong and i will keep reading the posts here and joined in where i see it fit.

Good question man
