Is the speed of light a logical or fundamental limit?
What I mean by logical limit is this. Consider temperature and the Kelvin scale. Zero Kelvin is the temperature at which matter is completely void of motion and therefore, energy (except for that of its mass?), so going lower than this makes no sense; you can't have less than zero energy.
Is it the same for the speed of light? As I understand it, the speed of light is a proportionality constant between space and time. Relativity tells us that with enough energy, you can technically shorten your travel time arbitrarily, no matter the distance, by approaching the speed of light. But the fact is, to a motionless observer, you can never go faster than the speed of light. Information can never travel between two points in space faster than the speed of light.
So which is it, is the speed of light a logical or fundamental limit? If it is a fundamental limit, doesn't that imply something serious about the universe? Why is the speed the speed of light precisely what it is? Why not 1.1c or 1.254c? Obviously the value changes based on the physical units, but the fact is that it has a definite value. Doesn't this imply that certain choices were made and that the universe was designed?
