What is the root source of "Light"?

I'm not talking about converted/transformed energy via external sources, i.e. Electricity or heat transformed to Light.
Whats the root source?
Energy itself?

Welcome to PF!

The unverse started with a lot of energy: In the beginning, it was hot and dense. All energy that exists today, including light, is ultimately derived from that initial state.
