It is possible to get energy out of matter, but is it possible get matter out of energy?!?

Question

If E=mc2 is true. why can't it be other way around?!?

Answer 1

It can definitely be the other way round and it is.
It is possible to obtain matter out of energy.
The point of concern here is pair-production and annihilation.
In annihilation a particle and an anti-particle annihilate to form two gamma photons. The reverse is also possible theoretically.
But the problem is that creating matter out of energy requires extremely high energy densities.
I thing scientists at CERN have already succeeded in this task and have created anti-matter particles

Answer 2

It does work both ways.

In nuclear reactions, a very small amount of mass is converted into energy.

It is also possible for energy to be converted into mass. For example, in the "pair production" process, a photon of light (which carries energy) collides with an atomic nucleus and produces an electron and positron pair.

Answer 3

yes it is possible becz it is stated by E=mc^2 i.e
"both mass and energy are interconvertible"
at cern it has been proved sucessfully throgh experiment the pair production and annihilation of matter are the coterms of the same theory.

Answer 4

In theory it should be possible. In practice we are not even close to be able to do this.
