What is the meaning and proof of Einstein’s E=MC2?

Basically means that mass can be converted into energy.  You want proof?  Go search "nuclear weapon".

Yep.  It's called metaphysics.\n\nWhy do you think Einstein introduced his 'fudge factor' in his first Theory of Relativity?  Because he didn't like the metaphysical implications of the truth.  Fortunately, his contemporaries called him on it and he 'fixed' it and won the Nobel prize.\n\nSaid differently, if E=MC (squared), then energy can be converted into matter and vice versa.  The necessary implication is that neither can come from nothing, which is scientific evidence of there being something supernatural that created the known universe.  \n\nI call it God.  What do you call it?

ITS [E=MC^2] - THE CONSERVATION OF MATTER AS ENERGY.. IT MEANS IF WE PUSH AN OBJECTS WITH A SPEED OF SQUARE OF SPEED OF LIGHT THEN THE ENERGY PRODUCED IN THE COVERAGE OF THE DISTANCE WITHOUT RETARDING OF 1 GM OF ANY MATTER OF DENSITY ABOVE 5GM/CM^3 WILL BE EQUAL TO THE ENERGY PRODUCED BY 10000KG OF U235 USED IN NUCLEAR REACTOR...

Hai Shaumik\nBy Einsteins energy mass relation E=mC^2 , but mass is inversely proportional to velocity\nA body with small mass have high velocity compared to a body having greater mass. This implies that a body having zero mass moves fast. There is no such object having zero mass. so no body can move with greater or equal to velocity of light

By relativity, E = Mc2\n\nIf E = 4 X 10^6 J, then....\n\n4 X 10^6 / c^2 = 4.45 X 10^ -11 kg\n\nWhere C = 299,792,458 m/s

Really basically, E=mc^2 (be sure to always write m and c as lower case) is the relationship between rest mass and energy. The conversion is pretty simple. The constant c is the speed of light defined as 299,792,458 m/s.\n\nWhat is more useful is perhaps an understanding of just how really huge an amount of energy that makes for even a small amount of mass. This is the reason why nuclear reactions (which convert mass into energy) are so energetic by comparison to chemical reactions (in which mass is more or less conserved).

it is an equation by Albert Einstein showing that energy and mass are interchangeable.\n\nE is energy\nM is mass\nC is the speed of light\n\nthus energy equals the amount of mass multiplied by the speed of light squared.

It is just a reference to E=mc^2.  It can be through fission or fusion, so yes you are surely correct.

The energy in matter is equal to its mass times the square of the speed of light.

E=mc^2, \nso energy can definitely be converted to mass. Use the equation i quoted above\nE is the energy , m the mass and c is the speed of light.\nThis equation is called the mass energy equation.\nThe nuclear fussion reaction is a nice example to show this fact.\nc the second link to know more

Equivalence.\n\nPhysics had long treated many things of being of entirely different natures.  Matter was concrete.  Absolute.  It followed laws of motion and the like.  Energy, on the other hand, was ethereal, zinging around and through the matter.  It is not ridiculous that physicists had thought this way - this is much of our experience of the physical world.\n\nE=mc^2, however, suggests that this is just not so.\n\nLiterally, it states that matter -IS- energy.  And conversely that energy is matter.  There is no 'special' status for one or the other.  Baseballs have a wavelength like any chunk of energy, and energy must occur in packets like any chunk of mass.  While quite simple in its statement, it is pretty staggering in its implication.\n\nFor example, it is used to explain how stars run (fusion turns minute amounts of mass into energy), explain the expansion of the universe (free energy turns into particle pairs which exert an outward pressure on space itself), and why photons which have no rest mass, can nonetheless push things around with impact (their speed and energy GIVE them mass).\n\nIf you want to use the equation itself, make sure your units match up.  If you use kilograms for mass and measure the speed of light in metres per second, energy will be in joules.  Hope that helps!

They mutually anihilate into energy (generally in the form of gamma-rays).  The energy they produce is the based on the sum of thier masses, and Einstein's famous E=mc^2 equation.

E is energy.\nm is mass.\nc squared is the speed of light squared.\n\nThey had a TV show on PBS about Albert Einstein yesterday. You just missed it! \nE=mc squared is Einstein's "theory of relativity".

The theoretical physics equation E = mc2 states a relationship between energy (E), in whatever form, and mass (m). In this formula, c², the square of the speed of light in vacuum, is the conversion factor required to formally convert from units of mass to units of energy. In unit specific terms, E (Joules) = M (kilograms) · (299792458 m/s) 2.\n\nMeanings of the formula\nThis formula, which was discovered by Albert Einstein, proposes that when a body has a mass (measured at rest), it has a certain (a very large) amount of energy associated with this mass. This is opposed to the Newtonian mechanics, in which a massive body at rest has no kinetic energy, and may or may not have other (relatively small) amounts of internal stored energy (such as chemical or thermal energy), in addition to any potential energy it may have from its position in a field of force. That is why a body's mass, in Einstein's theory, is often called the rest energy of the body. The E of the formula can be seen as the total energy of the body, which is proportional to the mass when the body is at rest.\n\nConversely, a single photon travelling in empty space cannot be considered to have an effective mass, m, according to the above equation. The reason is that such a photon cannot be measured in any way to be at "rest" and the formula above applies only to single particles when they are at rest. Photons are generally considered to be "massless," (i.e., they have no rest mass or invariant mass) even though they have varying amounts of energy.\n\nThis formula also gives the quantitative relation of the quantity of mass lost from a resting body or an initially resting system, when energy is removed from it, such as in a chemical or a nuclear reaction where heat and light are removed. Then this E could be seen as the energy released or removed, correponding with a certain amount of mass m which is lost, and which corresponds with the removed heat or light. In those cases, the energy released and removed is equal in quantity to the mass lost, times the speed of light squared. Similarly, when energy of any kind is added to a resting body, the increase in the resting mass of the body will be the energy added, divided by the speed of light squared

I know Einstein came up with it and it deals with energy.\n\nEnergy(E) = Mass(m) * Speed of Light(c2)
