Gravity isn’t a particle like light is, so why is it bound by a certain speed? Why wouldn’t it be instant?
In: 5
The speed of light is actually the speed of causality itself in our universe. It is not just as fast as any particle can go, it is as fast as anything at all can go.
This includes any sort of cause and effect and any interaction things may have with one another.
Instantly is not really a thing. Things can happen in two places at the same time, because “at the same time” is not really a thing that makes sense in our universe.
We can pretend that instantly exist in our every day life where distances are relatively short and the difference between “instantly” and what is really happening are small enough to ignore for practical purposes.
The real problem is that our naive understanding of how speed works at all is wrong. What we normally think of how it works is wrong by a little and close enough under normal circumstances but gets really wrong outside our normal experiences.
Also we aren’t 100% sure how gravity really works.
