    Why is C squared in the famous formula E=MC2?

    Why is the constant C squared in Einstein's famous formula E=MC2?
    I know there are supposed to be math reasons for this but doesn't it seem odd that the "constant" can even be theoretically squared?
    If a spaceship traveled at the speed C squared it would instantly be transported back in time to before the Big Bang.

    C is the speed of light. I have also been confused why C is even used in the formula, that too exponentially. Theoretically, travelling at the speed of light would make time travel possible. So this formula is supposed to be calculating the amount of energy spent by an object of mass 'm' to time travel, if there was such energy smile

      Not sure what you mean. I am no maths wiz!
      Isnt the formula saying how much energy exists in matter?
      C is used as its supposed to be THE Constant. Why square the constant when it cant be squared?

      Yes it's the energy formula. C is the constant whose value equals the speed of light.

    The "speed of light" squared or (299,792,458 metres per second)^2.

      That's pretty fast! Thought that was kilometres per second?
      I am curious as to why the formula ends up squaring the speed of light which in theory can't even go one digit faster that C.
      Sometimes I think Einstein was joking.
