Relativity applies to the universe only as we know it. Sorry you don’t believe people might learn more.
“Sorry you don’t believe people might learn more.”
No, it’s not that I don’t believe that. I certainly do.
It’s just that some things are so clearly confirmed that the likelihood they will ever be found to be proven wrong is infintessimal, and this is one of them.
It’s not like we can’t tell when a theory is an incomplete description of reality. That is usually quite apparent from the beginning, or becomes apparent rather quickly when we compare the theory’s predictions to observations. And the signs of that simply aren’t there in the case of what we know about matter and the speed of light.
Therefore, the only reason to think that we, or some imaginary “aliens”, might find a way around this law, is if one is intent in engaging in wishful thinking. I try to avoid that.
