See just take an example there is a verry heavy book on a desk hold it and through it on the bench. You can hear sound that is energy. As you know energy is never created or destroyed. So it just converted in sound energy.

In the same way the atom's proton mass transverd to make energy. And don't confuse that energy is starting from here. The energy which is applied to the conversion is used.

If you understand and if your un satisfied ? common man! we will reaserch about it.

On nuclear fission, large nuclei is splitting up into smaller nuclei. In this reaction some mass is lost. The mass lost is known as mass defect. The mass losing is converted into energy as in Einstein's equation E = m.c2. As c=a constant with value equalent to 3 lakh (speed of light). A small mass is converted into a huge amount of energy.
Got it ?

Sun is itself a energy not a mass. It does not contain matter It is a ball of fire. Sun released energy due to conversion of hydrogen into helium called fusion reaction. Thus in case of sun there is not conversion of mass into energy.

The mass may convert into energy let us example the mass of the petrol convert into heat energy .We can use the theorem E=mc^2 to calculate the energy.

According to Einstein's mass-energy theory mass and energy are interconvertible in nature.

But, the energy can be converted into mass.

So, how long the sun will emit the energy?

How much Hydrogen is present in the sun to make the energy continuously?

According to Einstein energy equation,

E = M*C*C.

So in nuclear reaction energy is obtained by mass.

It's right energy can't converted into mass but mass can converted into energy.

If a sun emitting continuous energy then why it is not get finished yet.

According to Albert Einstein, Mass Energy relationship E=mc^2.
