Now we're getting into relativity. Fun stuff!

How is this relativity..?
Granted, I don't know what relativity is, and everything I've seen that explained it shot out of my head like gibberish x'D
Quote:
E=mc^2 is actually a simplification of the full formula, which is E^2 = p^2*c^2 + (m*c^2)^2, where p is momentum and m is rest mass, by setting momentum equal to zero (that is, considering an object at rest).

The full equation looks a lot like the Pythagorean formula :o. Why is it simplified though? Is it just so that I, as a student, can understand the formula (since we learned energy before momentum)?
...What about p = mv though? If the mass is zero, the p turns zero too
Oh wow, solar sails are like the stuff of fantasies xD. Makes me wonder though, if E makes up that equation, where things like thermal energy and the rest come in--though I haven't yet learned about any of those :x
