This question already has an answer here:
The idea of the speed of light being as fast as something can go is pretty well accepted. I'm wondering if the top speed might be (very slightly) higher? Lemme explain.
I was reading about particle acceleration, and how accelerating a particle to the speed of light would require infinite energy.
According to a quick Google search, the LHC is getting particles up to 0.999999991 c. For someone such as myself, I might as well consider that the speed of light. I mean, it's so close, right?
So what if in a similar vein, the speed of light is very, very close to the absolute top speed? Is that possible?
If the speed of light in a vacuum was something like 0.9999999999999999999999999999999999 to the absolute top speed in the universe, would we ever know the difference? (this number is just an example to show how the speed of light could be imperceptibly close to the absolute top speed, and yet still not be the fastest speed possible).
