But what then? What if we start thinking in some weird ways and come up asking ourselves if time has a 'speed'? What about 'existence'? And what about gravity? How does it propagate around? At what speed? Is it universally instantaneous? Shouldn't we try to measure it?
If gravity is instantaneous, then it indeed has an instantaneous speed and light, therefore, could not be assumed as the roadrunnner of our universe. If it is not instantaneous then, what is its speed?
Please indulge me now - for a while - with my exotic ideas. This is just some perhaps nonsensical brainstorming: it may be that gravity has the same speed than light, a lower speed or a higher one. If it were lower, then, by all means, we could surpass it somehow, since the only thing that we cannot reach, according to Einstein, is light.
What would happen if we could surpass gravity? My guess is that rather weird things would take place and that might offer some possibilities.
Then, if light and gravity have the same speed, two things occur to me: first, that light would remain as our champion, so far, but nothing else would be proved: still, we would not be able to assure anyone that nothing faster exists just because we proved that something is really slower.
In other words, to say that light is faster than anything else may be quite incorrect.
Second, that as long as we stay at a distance large enough from a celestial body that begins exerting some kind of gravitational influx, we may escape from its effects, and one wonders, what would happen then during events such as the Big Bang or the end of the universe?
