I have looked through some of the threads which discuss the fact that an object cannot move at the speed of light because it would require an infinite amount of energy. What allows us to state that it requires an infinite amount of energy? Is it because if an object were moving at the speed of light, then for:(adsbygoogle = window.adsbygoogle || []).push({});

E=[tex]\gamma[/tex]mc^{2}

where [tex]\gamma[/tex]=1/[tex]\sqrt{1-(v/c)^{2}[/tex]

v=c. With v=c, there is no defined value for E.

You'll have to forgive me. I have not taken Calculus in 10 years. I am probably not stating this correctly.

Thanks for any further explanation people are willing to give me.
