If we know the exact speed of light then it’s clearly not infinite. If that’s the cause, what is preventing us from sending something faster then the speed of light( ignoring our current technology limitations).
In: Physics
A smart guy named Einstein showed us that is you push something faster, which we already knew took energy, that energy gets added to the mass of the thing being pushed. He also showed that the more you push, the more and more mass is added, and it turns out by a formula that relation has a limit just before the speed of light — you can never push something all the way there, just closer and closer.
Light (or photons) have no mass, so they jump right to that speed, where (again) nothing else can catch them, ever.
