Gravitational Waves: Speed & How Objects Affect it

In summary, gravitational waves are ripples in the fabric of space-time produced by accelerating masses, travel at the speed of light, are not affected by objects that produce them, and can be detected using interferometers. All objects with mass produce gravitational waves, but only extremely massive and/or fast-moving objects produce detectable waves. The first detection of gravitational waves was made in 2015 by the Laser Interferometer Gravitational-Wave Observatory.

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.

Also, note that gravitational waves always propagate at the speed of light in a vacuum.
 

FAQ: Gravitational Waves: Speed & How Objects Affect it

What are gravitational waves?

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.

How fast do gravitational waves travel?

Gravitational waves travel at the speed of light, which is approximately 186,282 miles per second.

Can objects affect the speed of gravitational waves?

No, the speed of gravitational waves is constant and is not affected by the mass or velocity of the objects that produce them.

Are there any objects that do not produce gravitational waves?

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.

How are gravitational waves detected?

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.
