## Matter, Antimatter and Einstein’s equation

It is my understanding that when **antimatter** comes in contact with matter that there is nothing left but pure energy.

And since energy and matter are interchangeable (E=Mc^{2}) doesn’t that mean you are actually left with all matter and no antimatter?

*Asked Ken*

**Answer**:

The equation **E = mc ^{2}** tells about

**mass – energy relation**and both matter and antimatter has a

**positive mass.**

## Mass Energy conversion and the Big Bang

Ajesh Asked:

Respected sir, in the famous theory of Albert Einstein which is of mass energy equivalence he stated a formula E = mc^{2} .

sir does this mean that mass can be converted in to energy or the opposite will happen .

it is even stated in the big bang theory that the universe was created with respect to the above theory is that so?

Answer:

The mass energy conversion and the equivalence is a widely discussed topic in relation to the creation of the universe or the Big Bang.

There is some energy missing in calculation when we consider the equivalence; this is called dark energy.
