Give me an example of where matter is created from energy in the universe.
The Big Bang is not an answer that is satisfactory. Mater is constently changing to Energy is there an example of the reverse?

Hello Customer (name blocked for privacy) and welcome to JustAnswer!

Yes, here are two examples:

1) Natural conversion of energy to mass: Gamma rays of sufficient energy often convert into electron-positron pairs when they have a glancing collision with a heavy nucleus.

2) Man-made: Particle accelerators convert energy to mass.

For an article about these two events check this webpage:
