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
It is instant, at least as instant as anything can be in our universe.
The speed of “light” is misleading. Light moves at the speed of *causality*. We call it the speed of light because light was the most prominent phenomenon to move at this speed when the term was coined, and it’s easier to talk about something people can see than not.
Gravity moves at the speed of causality because thats the fastest any phenomenon can propagate in our universe.
