This is the situation when material object is moving at the speed of light (v=c).
you end up with something divided with zero, which is infinite number.
Ergo, nothing with mass >0 can move with the speed of light.
But, 0/0 could be any number.
That is why photons (they have rest mass equal zero) can and must move with the speed of light....
