I cannot understand the mystry behind e=mc2?

Answer 1

The formula E=mc^2 spelled out expresses the amount of Energy (E) that is contained, or that can be released from an amount of mass (m) is equal to the amount of mass 'times' the speed of light (c) squared (^2). The measurable proof of that is the Atomic bomb.

Early on, the Germans determined that Uranium was fissionable, creating energy, but was not explosive. They also discovered that by processing Uranium through a nuclear reactor, they could create the more explosive form, Plutonium. They were hampered by not having enough 'Heavy Water' which is used as a moderator to slow the speed of the uranium molecules, sustaining the nuclear reaction.

America created the Manhattan Project and beat the world in creating the first nuclear weapon. The measured results proved Einstein's theory to be mathematically accurate.

There you have it.

Answer 2

There is pretty much no mystery at all. It has been confirmed experimentally.
This is the equation for the theory of general relativity; The energy of an object is equal to the mass times the speed of light squared.

Answer 3

It is not that hard to understand. What it basically says is that mass is energy and energy is mass. Energy and mass can be interchanged, but only if you multiply your mass by the speed of light squared. This is just a theory mind you, and has not been tested, even though it is widely supported and generally thought as true in the scientific community.

Answer 4

There is no mystery, now that the equation has been revealed.
Until Einstein, however, no one had concieved that mass and energy were two manifestation of the same stuff, and that under the right conditions, matter could be turned into energy and vice versa.

Answer 5

In Newtonian mechanics, energy in free space is just .5mv^2. This is invalid in special relativity, so when Einstein derived its more general form in this theory, he got a function of velocity OK, but there was this funny extra mc^2 term on the end that just wouldn't go away.

Answer 6

it's just a formula that gave Einstein famous. The formula is mass-energy equivalence. The energy, given by the symbol of 'e' is relates with mass; m and speed of light in vacuum; c.
So, in simple word.. The energy has a mass equivalence and vise versa.

Answer 7

the sun uses 4,000,000 tons of hydrogen every second to create slightly less than 4,000,000 tons of helium, the missing mass has been converted into energy, the heat and light that makes the solar system what it is. the C in the formula represents a constant, the speed of light which is 186212 miles per second, multiply that number by itself and you have a huge number in units of energy. six pounds of enriched uranium converted into energy provides the power of a fission bomb.

Answer 8

The equation is pretty simple really. E stands for energy and M stands for mass. That should be pretty obvious. C stands for the speed of light. Which is like 267,000 miles per sec or something like that. This equation was used to create the atomic bombs for the U.S. that were used in War World II

Answer 9

e=mc² is just a relationship between mass and energy. But, untill Einstein figured it out, the idea that mass and energy were just different 'forms' of the same 'thing' (like ice and water are different forms of trhe same thing) was totally foreign to the world of physics.

FWIW, time and space are also different forms of the same 'thing' ☺
