The discussion centers on the detection of gravitational waves emitted from black holes, exploring the properties of gravitational waves, their interaction with gravity, and the mechanics of their detection, particularly in the context of LIGO's observations.
Participants express disagreement regarding the mass of gravitational waves, with some asserting they have mass while others refute this claim. The discussion remains unresolved on the implications of gravitational waves emitted from black holes.
There are limitations in the assumptions made about the properties of gravitational waves and their detection mechanisms, particularly regarding their mass and speed.
negative said:gravity waves are supposed to have mass
negative said:they are supposed to be effected by gravity itself
negative said:how are we supposed to detect gravitational waves emitted from a black hole when none can get out?
thank's that clears thing up. but , don't gravity waves move slower than the speed of light? 0_o still no mass?PeterDonis said:No, they don't. They carry energy, but they have zero stress-energy.
In the sense that they follow the geometry of spacetime, yes.
The gravitational waves detected by LIGO were not emitted from inside black holes. They were emitted from outside the horizons of merging black holes.
