Very loosely. The "big bang" isn't really as solid as many think. But relativity is. So, astrophysicists try to graft all kinds of jerry-rigged ideas to the big bang to make it fit with relativistic observations. Like "inflation", "dark matter", "dark energy", and so on.

The only REAL relation of E=MC^2 to the big bang is the red shift.

It is one of the most important facts that contradict the Big Bang theory. If there was at the beginning of the Big Bang neither energy nor matter, why the universe has now a tremendous amount of both?
If a very small amount of matter at the beginning was converted to energy - then why was there an increase in matter and not a decrease?
If at the beginning all the energy was converted to matter, where was more energy coming from to inflate that initial amount of matter?
All those questions come up if we are trying to explain the Big Bang theory with the wise knowledge of Albert Einstein. He was not a believer in the Big Bang theory.

It's more about Einsteins theories on Relativity.

Einstein's theories helped to predict the nuclear chain reaction and atomic bomb potential.

It also helped with the H bomb and the Big Bang is close to the H-bomb in concept.

It has to do with nucleus fusion, which generates heat and other forms of radiation.

Now, it would seem that when you have a gravity well of a smaller magnitude and a collection of hydrogen compresses around this fusion starts to occur and helium and other elements are created and we get what we call a star.

In the case of the Big Bang it was postulated the gravity well was comprised of all the mass in the universe and was hence a huge gravity well so large it kept light from leaving

G=C

Where G is gravity

Einstein predicted a lot of this

So when this mass starts going fusion it start expanding rapidly and gravity weakens as mass moves outward.

The first mass to escape was Cosmic Rays

Then free small particles that eventually would form Hydrogen

Now three scientists separately came up with math to describe the propegation of this mass as it expanded out of the singularity making an enlarged universe.

They all used Eistein's math and Relativity explainations in their work to describe how all of this works.

Including that things would be moving away from us in all directions as observed on the Earth. Hubble showed this to be true.

The big unknown is the total mass of all the material in the universe.

This controls whether the universe continues to expand forever, (Is so what into ?), or whether eventually a balance is reached and the universe starts to collapse upon itself eventually reaching the big crunch. That is all the mass compressed into an infinatly small space, therefore with infinite density.

Which is precisely what existed at the big bang some 15 billion years ago. So maybe we have an oscillating universe with a lifespan of at least 30 billion years.

Measurement of red-shifts show that the universe is still expanding but present knowledge of so called "Dark matter" does not allow a definitive answer as to the total mass of the universe.

e=mc^2 is the equation that relates between energy and mass (particles)

The relation I can see is that after the big bang, the universe is a huge hot soup of energy in the form of radiation. I think it's called the radiation era, whatever. As the universe expends, it cools down (same amount of energy, but the size increase, so it cools down). Energy begin to turn into particles, fundamental particles, and there were 2 version of it, the normal particles that we see today, and anti particle. normal partical becomes the dominant particle and anti particle disappears, the rest is history.

In an atomic bomb, you're converting a particle back into energy, and the energy is alot as we've seen in Hiroshima and Nagasaki. that equation relates the amount of energy in a particle.

The bottomline here is that, there is an underlying symmetry between particle and energy, and E=mc2 is just the amount of energy in a mass, simple as that, but we don't know what's same between energy and particle.

In the big bang, everything started out as the same, there is no 4 fundamental force, no particle, everything is one single thing and current theory cannot explains that.

Normally energy E is used to be calculated with this equation. But at the time of Big Bang the reverse happens. Mass itself started get produced due to the abundant energy resulted due to Big Bang. The initial mass i.e. the subatomic particle and matter obtained due to the Big Bang would have been as

m = E/c2

The Equation was first Published by Henri Poincare 1n 1901,about four years before Einstein Used it in His theory of Relativity. He did not relate it to the Big Bang theory of singularity.
The equation defines the Energy neccessary to assemble a mass structure at the speed of light. Which impies that assembling of mass structures took place at the speed of light.
At the speed of light, mass formation of the Universe would have taking place at 9.4732203 x10^70 kilograms per seconds.

Howeve per Big Bang theory the mass formation time of the Universe would have taking places in 1.35 x10-43 seconds yielding mass formation velocity at the rate of 1.481 x10^96 kilograms per seconds. This formation rate exceeds the speede of light.
This theory indicates that mass of the Universe was formed in a very short time.

Energy formation equation of E=MC^2 informs us that Energy exists in terms of three components; mass and
distance travelled by the mass ,and time traveled by the mass.These are the basic components that fit the energy equation.
If Big Bang theory refers to what the basis that existed before creation of the Universe .There just was no Universe. If there was no Universe ,then there was no energy and no mass and no relativity of time to describe the Process of energy.
Hence how can we relate the formula to the Big Bang =we cant. Unless Creation did not take place in the Inside of the geometrical volume of the Unvierse containment ,but rather externally.
Hence ;The Creation phenomena was more likely an external One rather than an internal one. For more explicit revelation about the Creation of the Universe refer to The Biblical Record of Creation.

Einsteins theory is used to calculate how much matter is in the known universe, so in reality "That word again!" we can calculate just how much energy was expended in the "big bang" The only fly in the ointment though, is this. If matter is consumed to produce energy during the big bang, why is there still matter left in the universe? And why did the chain reaction stop?

E=energy and M=mass and C= the speed of light,the one constant in the entire universe.So in the beginning when the Hydrogen particle which composed all matter in the universe exploded, in what was known as the big bang, this equation explains the change of mass into energy, in a simple explanation;a small amount of matter can be converted into a huge amount of energy via nuclear fission.

well...think about it...."E" is Energy, "mc2" is an amount of matter, and it means that any given amount of Energy is equal to an amount of matter....! So any energy or matter in the universe can be calculated using that equation.
