But I don't understand how you came to that reasoning.
Just because we don't know how to, why can't we?
It's like saying time travel is impossible, well who knows give it 100 yrs and we could be. Then what for everyone saying impossible.
We don't understand how to do something is not reasoning for saying it's impossible.
I'm not going to say anything is IMPOSSIBLE just impossible based upon our current understanding.
Light can certainly be slowed down, so it might be possible to sped up. Light speed might vary in different parts of the universe. It might change over time. Along with light everything else might be able to move faster.
There has certainly been prominent scientists looking into whether the speed of light has always been the current constant.
From everything we currently know though, you can't go faster than light and it's been tested many times. One of the pillars of the scientific method though is that everything is subject to review and retesting.
