In the grand body of the universe and even our own solar system the speed of light is incredibly slow on the cosmic scale. Why does it have this speed limit ? It is theoretically possible to go faster than light ? Or is light just the fastest thing we have observed thus far ?

Light speed is just how our universe works. It’s like a universal speed limit set by the laws of physics. This speed – 300,000 kilometers per second – comes out of the equations of Einstein’s theory of relativity, which describes how space and time are connected.
It’s not about resistance, it’s about the nature of space and time themselves. According to current understanding, nothing can move faster than light. If something could, it would mess up the cause-and-effect in our universe and violate the theory of relativity.
So yes, as far as we know, light (and other electromagnetic waves) is the fastest thing in the universe.
