Ok i read this whole thing, and now i'm a lil dizzy

Now i'm not sure if it was said but one thing that has to be kept in ming is that the only reason why light goes the speed of light is because it has no mass - light is just a form of energy (photons - which have no mass - which are actually moving in a wave form which is called an electromagnetic wave). So anything with any mass, no matter how small will never go at the speed of light.

And like someone said, the faster you go the more energy you need .

The speed of light is the fastest possible speed. The reason is that, in order to accelerate an object, you need to use energy. The more massive (or "heavier") an object is, then the more energy it takes to accelerate it.  As an object moves faster, it appears to gain mass (or become heavier). We don't notice this in everyday life, because this effect really only becomes noticeable when you get very close to the speed of light, but scientists have measured and verified this theory in laboratory experiments. In fact, if an object gets very very close to the speed of light, it's mass goes up so fast that it can seem to be infinitely heavy! At this point, it is impossible to gain enough energy to accelerate the object any further.

And here's a twist to that theory! If 2 photons emitts from the same source, are not their speed, compared to each other, twice the light speed ? (In other words say a photon - in motion - releases another photon)

Simply put, No! This is a very strange thing about special relativity. Einstein's theory states that, no matter whether you are moving or standing still, light always moves at the speed of light. So, if you were on one photon and looking at the other photon, it would appear to be moving at the speed of light.

Mathematically, the ideas behind special relativity are very simple, and can be understood with basic algebra. However, a physicalunderstanding of what special relativity means is very difficult to achieve. I'm still not certain that I truly understand it; I just accept it as true (since repeated experiments show these theories are true).

So yea, here's my input on it
