AI Thread Summary
The discussion centers on whether the effects of gravity are instantaneous or have a finite speed. It references the established fact that light takes time to reach us, raising the question of gravity's propagation speed. Current understanding suggests that gravitational effects propagate at the speed of light, meaning if a massive object like the Sun were to disappear, its gravitational influence would also take time to be felt on Earth. The hypothetical scenario of teleporting a moon raises further questions about the timing of gravitational effects in such a case. Overall, the consensus is that gravity does not act instantaneously but rather at a finite speed.

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 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
