      not for someone or for a particle with mass. Only massless objects can reach the speed of light

      Mario’s right, only things that don’t have any mass can travel at the speed of light. But if you had a lot of energy you could get very close to travelling that fast.

      No. There’s a theoretical thing called a tachyon that can, but we’ve never seen any evidence for them.
