Has this ever been solved?
Is it even possible to solve this?
Lets see Energy is equal to Mass times Carbon squared?
Whats not solvable?

E = mc2 means: "energy" = "mass" x "speed of light" squared.
It expresses that mass is a form of energy. Until around 1900 it was believed that mass was always conserved; i.e. mass cannot appear or disappear. However, we now know of processes in nature where a tiny bit of mass disappears and is converted into a lot of radiation energy. Therefore mass is now thought of as a type of energy.
For instance, if 1 milligram (10^-6 kg) of mass is converted into radiation, the energy produced is
... E = m c^2
... ... = (10^-6 kg) * (3*10^8 m/s)^2
... ... = 3*10^10 J
... ... = 30 megajoules,
which is quite a lot!
This explains how the sun is able to produce so much light. In the nuclear fusion of hydrogen into helium, a small percentage of the mass is converted into radiation energy. The sun loses weight; we get the light!
The formula was derived by Albert Einstein, who wished to introduce "rest energy" of mass. In his theory of relativity, the value
... gamma = 1 / sqrt(1 - v^2/c^2)
plays an important role. When you look at something moving at speed v, the length of that something seems to be gamma times smaller and the time seems to go gamma times slower. In daily life we don't see much of this because gamma is close to 1.
For mathematical reasons, Einstein wished to apply this value gamma to energy as well. If the "rest energy" of something is E0, we would observe its energy to be slightly larger, namely
... E = gamma x E0
In traditional physics, the (extra) energy due to motion is called kinetic energy. The formula for kinetic energy is KE = 1/2 m v^2. The two formulas match if
... E - E0 = KE
for objects at low speeds, or in other words,
... (gamma - 1) x E0 = 1/2 m v^2
As long as v is small compared to the speed of light, gamma is approximately equal to
... gamma ~ 1 + 1/2 v^2/c^2.
This shows that if E0 = m c^2 is the rest energy, Einstein's theory fits the traditional theory.

C= the speed of light. It wouldn't really make any sense if it were carbon. Perhaps that is why you were confused.
But to answer your question, it is solvable. Find the mass for any given material and times it by 299,792,458 m/s squared (speed of light.) and you come up with the amount of stored energy existent in that quantity of matter.
This statement is very significant in physics. It is important to realize that there is a relationship between the mass of an object and it's energy.

Yes, it has been solved ,and if you Understand it you could win a Nobel Prize.
E= the Energy required to keep a mass structure into an integral architecture.
M= the mass quantity that the mass contains
C= the velocity that the masses making up protron ,neutron, and electron, are moving ,which is the speed of light.
You make become the next Einstein some day = it was a very good question. keep up the good work.
Note; its not carbon that gets squared.

Interesting. This is a partial answer.Firstly, let us interpret the eq'n. E is the amount of energy that should be gotten if we could tansform the mass, m. And c squared is the scalar factor - the speed of light in a vacuum. (c=3*100000000m/s and a bullet can travel up to 400m/s).
Special labs have been build to experiment with this theory and so far the lab results are reflecting some truth in the formula.
Remember the atomic bomb that killed a lot of people in Japan? It was build on this principle.

The small c is not the same as the symbol for carbon.
This is not my words but Wikipedia...it explained it very well.
In physics, mass–energy equivalence is the concept that all mass has an energy equivalence, and all energy has a mass equivalence. Special relativity expresses this relationship using the mass–energy equivalence formula
where
E = the energy equivalent to the mass (in joules),
m = mass (in kilograms), and
c = the speed of light in a vacuum (celeritas) (in metres per second).

This is the famous Einstein's equation where C is NOT Carbon but the velocity of light in vacuum.Imagine, light travels at 3 lakh kilometers per second. Square of that in fundamental unis is an enormous figure. This is proved in the atom bombs and nuclear reactors. U.S.S.Nimits, the nuclear powered warship is refuelled only once in TEN years. Such is the immense power of E = mc squared. Is it clear?

c is the speed of light, which is 3*10^8 m/s. It is a formula that relates the mass of atoms to energy. it is solved by plugging in the variables that you have.

HUH? that is the answer moron!!! energy ir equal to mass times carbon squeared!! Einstein solved this it means we are all energy everything is energy.

You are kidding right? The C stands for the speed of light.

c = speed of light, first of all... second of all, what's your question?? It is solvable, if that's what you're worried about
