SUMMARY

The discussion centers on the propagation of gravitational effects and whether they are instantaneous or have a finite speed. It is established that gravity propagates information at the speed of light, meaning that if a massive object like the Sun were to disappear, its gravitational influence would not be felt instantaneously on Earth; rather, it would take approximately 8 minutes for the effects to be observed. This aligns with current scientific understanding of gravitational fields and their interaction with mass.

PREREQUISITES
  • Understanding of gravitational fields and their properties
  • Familiarity with the speed of light as a constant in physics
  • Basic knowledge of general relativity and its implications
  • Concept of information propagation in physics
NEXT STEPS
  • Research the implications of general relativity on gravitational waves
  • Explore the concept of gravitational time dilation
  • Learn about the speed of gravity and its measurement techniques
  • Investigate the relationship between mass, gravity, and spacetime curvature
USEFUL FOR

This discussion is beneficial for physicists, astronomy enthusiasts, and anyone interested in the fundamental principles of gravity and its effects on celestial bodies.

I read an interesting article a couple of years ago, unfortunately I don't remember where. It had to do with the affect of Gravity on planets. We already know the speed of Light and that it takes so many minutes or hours for the light of a planet to reach us. I'd like to know if Gravity's affect is instantaneous or does it have a "speed" of some sort.
Here's a hypothetical situation: we've invented Teleportation of mass, we even built a machine big enough to teleport a moon. If you teleport something of that mass and it arrives instantaneously, does it's gravitational affect on nearby objects take a finite amount of time to happen or is it also instant?
 
Physics news on Phys.org
Gravity propagates at the speed of light.
 
Not.

Under current observations, it would seem that the gravitational field propagates information at the speed of light. So if the Sun were to instantly disappear, it would take ~8mins for us to know.
 
OK, thanks for the replay!
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
