Question

Why can't anything with mass travel at light speed ?

Answer 1

Explanation:

As objects travel faster and faster, they get heavier and heavier – the heavier they get, the harder it is to achieve acceleration, so you never get to the speed of light," says Roger Rassool, a physicist at the University of Melbourne, Australia. "A photon actually has no mass," he says.
