Gravitational Attraction of Motionless Masses

Click For Summary
SUMMARY

The discussion centers on the gravitational attraction between two motionless masses in a universe devoid of time. Participants argue that while gravitational fields exist, the absence of time renders the concept of motion meaningless. They explore analogies, such as the universe shrinking uniformly, to illustrate that without a reference point, no change can be perceived. Ultimately, it is concluded that while gravitational forces can be measured, the perception of motion is fundamentally flawed in this hypothetical scenario.

PREREQUISITES
  • Understanding of gravitational fields and forces
  • Familiarity with the concept of point particles in physics
  • Knowledge of the equivalence principle in general relativity
  • Basic grasp of measurement concepts in physics
NEXT STEPS
  • Research the implications of the equivalence principle in non-uniform gravitational fields
  • Study the concept of tidal forces and their detectability in gravitational fields
  • Explore the effects of changing acceleration on physical bodies
  • Investigate the philosophical implications of motion and measurement in theoretical physics
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the philosophical aspects of motion and gravity in a time-less universe.

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.

Assuming a universe with only space and two motionless masses, would the two masses start to move toward each other?
Good question man
