Isn't gravity just a fundamental force? Could it be matter reacting to gravity? Light is energy but gravity is not energy and has no mass so how can it create something out of nothing? How is hawking radiation even possible unless something else was involved?
And can someone help me understand in layman terms how current physics posits that gravitation is generating light or even hawking radiation?

Hawking Radiation didn't depend on gravity either, it depends on an event horizon. Any phenomenon which would separate virtual particle pairs would produce it - i.e. the edge of the observable universe would do it too.
That doesn't make sense. Everywhere is the edge of the observable universe to someone.
Any virtual particle pair which appears along that horizon can potentially be caught on the wrong side of it - i.e. one virtual particle is in a part of space which is now far enough way to be expanding faster then light, whereas the other particle is at a location close enough that it is not.
At the moment that happens, there's a particle or photon which is now inside the light cone of a distant object, paired with a particle that it will never meet again because it's outside of it.
As a result, you get Hawking radiation: because one particle can go off and interact with your universe, but it's partner will never be able to causally effect anything inside that horizon again. So the virtual particle has to become real.
So the trick to creat this light in todays environment would be to make a gravity amplifying device similiar to a https://en.wikipedia.org/wiki/Gravity_laser and overlay the amplitudes? That can be easy. Just have a microscopic black hole particle go back and forth in a field..
Thomas Pynchon was ahead of his time with his book title https://en.wikipedia.org/wiki/Gravity%27s_Rainbow

And I just upgraded all of my bulbs to LED...
All this time I thought that gravity creates heavy, not light.

Creating a microscopic black hole sounds like a great filter type of event.
But we only find out if we try, I guess.

Yes, but because space is expanding - i.e. there's a value of meters per meter per second for the expansion of space, then every point in space has a sphere around it of locations which are sufficiently far away that they are growing more distant at the speed of light.
