Question

What is e=mc^2 all about?

Answer 1

I know it's Einsteins's and that is has something to do with mass and energy,but I am in physics right now and we haven't learned anything about it or theory of relativity. :(

Answer 2

Does it have to do with the theory of relativity?

Answer 3

E = MC ^ 2 is perhaps the most famous equation of all time. It stands for E(energy) = Mass times the Speed of Light (C) squared. What this means is that if you take the mass of an object and multiply it by the speed of light (2.9 x 10^8 metres per second) you will then have calculated the amount of energy. As you can see, even a tiny amount of mass when multiplied by such a huge number (C) yields an incredible amount of energy. Releasing that energy can do everything from power cities (a nuclear power plant) to destroy them (a nuclear bomb). Further applications found in science fiction include Star Trek's famous warp drive technology that uses a matter/anti-matter reactor to release the energy of particles to power an entire space ship.

Answer 4

Ohhh that's cool, how can that energy be released?

Answer 5

He doesn't know. Lol

Citing your sources is nice.

Answer 8

I am pleased.

Answer 9

I thought that that cup was a beard and that you were Gandalf :p @brostep0s

Answer 10

It is the energy released in joules when mass in kilograms (i think) is converted to energy.

Answer 11

If i remember right energy can be released with fusion, fission, or decay.

Answer 12

E=mc^2
e=energy
m=mass
c=speed of light
so energy equals mass times the square of the speed of light

Answer 13

the direct relation btw mass and energy
meaning if you have some mass you can convert it to energy or vice versa you can start from energy and produce mass
the nuclear weapons use this principal of mass energy to create those deadly arsenals unfortunately.

Answer 14

Theory of relativity explains how space and time are playing key rule in what's called gravity. according to the theory when you set on a chair the weight of earth is pushing you down to curve the space you are setting on and so your weight has the same rule. It is corresponding to time dilation an such... read more about it in books you might get more feeling about it.

Answer 16

@Secret-Ninja where do you see a cup? that's my hand lol cx

Answer 17

Wow. I thought first it was a beard, then a cup, and now I see its a sleeve. I need new glasses. >.<

Answer 18

Forget glasses, I would try a telescope cx

Answer 19

lol yup.
