A star 10 light-years away explodes and produces gravitational waves. How long will it take these waves to reach the earth?
Homework Equations
The problem is, I don't know what equations to use or if it's just a matter of simple math.
The Attempt at a Solution
My answer is that it takes 10 years to reach the Earth, but something tells me that this is wrong. Can anyone help me solve this problem or tell me if my answer is correct?

Gravitational waves are ripples in the fabric of spacetime, caused by the acceleration of massive objects.
Gravitational waves were first detected in 2015 by the Laser Interferometer Gravitational-Wave Observatory (LIGO), which uses laser beams to measure tiny distortions in spacetime caused by passing gravitational waves.
Studying gravitational waves can help us better understand the behavior of black holes, the origins of the universe, and the nature of gravity itself. It can also lead to the development of new technologies, such as more precise methods for measuring distances in space.
No, gravitational waves cannot be used for communication as they are extremely weak and difficult to detect. Additionally, they are unable to carry information in a way that can be deciphered by humans.
The detection of gravitational waves from a neutron star collision in 2017 confirmed many theories about the behavior of these extreme objects and provided important insights into the production of heavy elements in the universe. It also marked the first time that both gravitational waves and electromagnetic waves (light) were detected from the same event, opening up new possibilities for multi-messenger astronomy.
