Question

what does E=Mc^2 mean?

Answer 1

google :)

Answer 2

google will give me wiki and wiki makes no sense :p

Answer 3

It means the Energy equate to Mass times a constant of variation

Answer 4

Energy is directly porportional to mass :)

Answer 5

E = energy, M = mass, c = speed of light in vaccum. The energy = The mass times the speed of light^2

Answer 6

and since C is just a constant, what this really says is that energy IS mass

Answer 7

Energy = Mass*Speed of light^2

Answer 8

to have energy you need mass?

Answer 9

?... I haven't done chemistry yet, I just want to know what it means in general human terms. Why is everybody so excited about it?

Answer 10

Because we finally know what energy is

Answer 11

so energy is...matter?

Answer 12

It can be interpreted as if the mass 'm' travels faster than the of speed of light it changes its form to energy.

Answer 13

Wait- since I have mass, does that mean I'm energetic?

Answer 14

:)

Answer 15

it means you have potential energy :)

Answer 16

I potentially have the energy to jog ten miles... true, I suppose

Answer 17

jog, roll, fall, shimmy and shake

Answer 18

you will see the energy if you light yourself on fire!

Answer 19

pyromaniacs united under one banner of physics

Answer 20

You have potential, but it requires to be extrapolated beyond the limits and you may change your form when you overstep the speed of light. Remember you 'd be no more a human being, you'd assume the shape of an Angel or some Jin. :)

Answer 21

I'd be HOT! (literally)

Answer 22

so that's how we know angels r beautiful...

Answer 23

It depends, if you wanna be hot, then you'd b Jin, otherwise Angel or Seraphims are cool and sizzling.

Answer 24

Tough question..:-)
