Can we convert energy into matter?

Question

well we all know the Einstein's equation E=MC^2

so then can we create matter using energy? or M=E/C^2?

Answer 1

No

Answer 2

Matter generation from energy occurs frequently in particle accelerators and cosmic ray showers. In fact, it's pretty much the entire point of particle accelerators.

Answer 3

Yes, but this is an horribly inefficient process.

In large particle accelerators, a stream of (usually) protons are accelerated to relativistic velocities and led to a target where they smash, creating a flow of very energetic gamma photons. Those photons (i.e. pure energy) will sometime undergo what is called "pair creation", usually an electron and its anti-particle the positron, the later usually not roaming far before it encounters an electron and gets annihilated (with the release of yet another gamma ray photon).

But technically, this was matter created from energy.

Answer 4

Technically, yes, but the power required would be enormous.

Answer 5

it would actually be M=E/C^2 if rearranged properly

umm, technically possible, but not by humans right now :)
