What speed do gravitational waves travel in matter. Is it a little less than c. Are their certain objects that slow it down a lot.
Gravitational waves are ripples in the fabric of space-time that are produced by accelerating masses, such as colliding black holes or merging neutron stars.
Gravitational waves travel at the speed of light, which is approximately 186,282 miles per second.
No, the speed of gravitational waves is constant and is not affected by the mass or velocity of the objects that produce them.
According to Einstein's theory of general relativity, all objects with mass produce gravitational waves. However, the strength of the waves decreases with distance, so only extremely massive and/or fast-moving objects are capable of producing detectable waves.
Gravitational waves are detected using specialized instruments called interferometers. These devices measure tiny changes in the distance between two points caused by passing gravitational waves. Recently, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected gravitational waves for the first time in 2015.
