perhaps you should work a problem out using the above formula
to check that.

in the above formula this part (1 - v^2/c^2) will result
in a negative number , or using the speed of light as the velocity causes the formula to fail.

because 1-1 = 0

and you cannot divide by zero.

Well, gentle readers, there goes Paul again. He refuses to notice the fact that I pointed out that division by zero gives an unusable answer, and therefore nothing that has a non-zero rest mass can travel at the speed of light. This is one of the things that has been a major point of Special Relativity every since it was introduced by Einstein. Therefore he has set up an impossible situation and tries to claim that it invalidates SR. Of course since the scientific theory of Special Relativity has been validated numerous times by careful scientific experiments and observations his complaints are totally off base. But that is his way, he just refuses to admit that he doesn't know everything and won't make an effort to learn what actual science teaches.

C is not the speed of light in a vacuum.
C is the universal speed limit.
