Make photons into some material?

[wolram]

Do scientists have the means to directly make photons into some material ?

What do you mean by directly and what do you mean by making photons in a material?

I mean, the raw, (material) used is photons, and the end result is something
of substance.

Oh, I misunderstood you a bit. Well you can make a high energy photon to an electron-positron pair.

Thanks inha, i asked the question as i can find nothing about how our universe changed from pure energy to a mixture of energy matter, i may not have looked in the right places.

Maybe you should have asked this in the cosmology forum. The regulars there should know about early universe stuff.

Thanks again inha, but they get a bit nebulous in that forum, i thought this one would be more to the fact.

I don't know where you read that the universe was once pure energy? As far as I understand the earliest universe was composed of plasma, made up of free floating ions, which are particles of matter.
