Hello everyone ;)
When we talk about speed, it's known that motion is relative.
I can say my speed is 0 relatively to my chair.
Is there any possible notion of "absolute speed", as there is no center of the universe ?
I believe that the answer will be no, as motion is relative, however I don't get the reason (and it might be because I don't really understand the concept of speed/motion).
But, when we say that a galaxy is moving at x speed, but what is it relative to ?
Once again, the question is difficult for me to express, but it's still worth trying ;)
