Is gravity faster than the speed of light?


Gravity (acceleration) and the speed of light (velocity) are measured using two different units of measurement for example KPH (velocity) and m/s^2 (acceleration). This is akin to asking how fast is a meter.

The answer is that there’s no answer.


thank you! :crazy_face:


so it COULD be faster than the speed of light…even if there is no question. I’m curious only because the speed of light cannot escape a black hole, so potentially gravity could be faster than the speed of light…OR the singularity is faster than the speed of light :thinking: (also, I’m not a scientist nor do I have any scientist friends other than Google…this I just me getting to be a kid again and ask way too many questions)


LOL…ok…well…that kind of turns into another question:

Can a black hole pull light into it so that light is travelling faster than the speed of light? How would that even be tested?


great question! and yeah, how would one even test that? You would think if we could build the Hardon Collider we could do a black hole test…but that could also result in creating a black hole itself…maybe we’ve already been sucked into a black hole and it just happened so fast we had no idea…ooooh the possibilities


Maybe those guys have a blog


So I guess according to the theory of relativity, if we consider gravity in terms of being a wave, then the wave is travelling at the speed of light in a vacuum. Which has been tested by looking at star locations around the sun during an eclipse.

Coincidentally though, I’ve never had the job of “scientist” either and I don’t know what supposedly happens in a black hole. Only ppl way smarter than me have that job title.
