everybody know that mass equals energie (e=mc²)
so how many megaton is the equivalent of the mass of the earth?

ok bomb

(im dutch, in dutch bomb = bom) :)

yep is enormous

i calculated a little les though:

4,2638*10^17 megatons
if you compare it to bomb tsar
the biggest bomb created by man
50megatons
lol

It is about 1.28 x 10^26 megatons, a number which is so big it has no name. Written out in standard notation, this is:

128,000,000,000,000,000,000,000,000 megatons.

To put it another way: It is more energy than the SUN emits in 42 million years.

If all this energy were packed into the space of one hour or less, the earth would be as bright as a supernova, and the explosion would be visible from faraway galaxies.

It is a very, very big bomb.

E= energy , M=mass , C= speed of light,

C squared is essentially C x C

so E= M x C x C

Basically the equation states that energy and mass are essentially the same thing and just appear in different states. One converting to another. e.g burning coal gives off heat and light energy, converting the mass into energy.

Or in Einstein's words,
"It followed from the Special Theory of Relativity that mass and energy are both but different manifestations of the same thing - a somewhat unfamiliar conception for the average mind. Furthermore, the equation E is equal to mc², in which energy is put equal to mass, multiplied with the [by the] square of the velocity of light, showed that very small amounts of mass may be converted into a very large amount of energy and vice versa. The mass and energy were in fact equivalent, according to the formula mentioned before [E = mc²]. This was demonstrated by Cockcroft and Walton in 1932, experimentally."

Earth's mass is 5.97x 10kg to the power of 24 or

5 970 000 000 000 000 000 000 000kg

The speed of light is

300 000 000 m/s

So 5 970 000 000 000 000 000 000 000 x 300 000 000 x 300 000 000 = 5.373e+41

or
537 300 000 000 000 000 000 000 000 000 000 000 000 000 joule of energy

A megaton is 4.18e+15 joule of energy or 4 180 000 000 000 000

so 537 300 000 000 000 000 000 000 000 000 000 000 000 000 / 4 180 000 000 000 000 =
12 854 066 985 645 933.014 354 066 985 646 Mt (megatonnes)
if the earth were to be converted into energy.

Can we not say that Einsteins Relativity Equation was the recipe or inspiration for the making of the atom bomb?

The number is so large that the human mind can't comprehend it so I won't bother calculating it.
E=mass of Earth(in kg) *300000000 * 300000000 Newtons

Yes the earth is a bomb.
If scientist had made A-bomb.
So every star that are highly activ can say bom.
