If the speed of light is the limit according to the relativity theory, is it a reachable limit, or un unreachable limit?
Also, if you got to the speed of light, according to wich point of view would that be taken?

Only something with no mass can go the speed of light. If something is going the speed of light, it cannot go slower. If something is going less than the speed of light, it can never be accelerated in such a way so as to reach the speed of light.

If something goes at the speed of light, it looks like the speed of light from ALL points of view. If observer "A" is moving toward the light, and observer "B" is moving away from the light, and observer "C" is just sitting there, ALL THREE will observe the light as traveling at the same speed (i.e., 186,000 miles per second).
Sounds impossible; but that's actually one of the fundamental principles of the theory of relativity.

Well you cannot travel at the speed of light. It is not possible according o the theory. Any object which attains the speed of light will have its weight infinity. And this can't be possible. So the spped of light is impossible to be reached by any object.

It is an unreachable limit. To accelerate an object to the speed of light would take an infinite amount of energy.
Basically, the energy you would have to use would be equal to more than the total energy that exists in the universe.
