Eli5: Why is light that fastest possible thing?

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).

There are a multitude of reasons. The first, and most basic to realize why it’s fundamental is that the bonds of atoms are actually made of photons. Oscillating electric and magnetic fields are what light is made of, and that’s what binds atoms together. Therefore, even if you got an object to the speed of light, then it would instantly rip apart into fundamental particles, because it would be going faster than the thing that holds it together.
