Has anybody ever investigated to see if there is a reciprocal of a black hole? If so what is it?

If energy cannot be created or destroyed, what was the energy that must have been put in to cause the big bang doing b4 the event?

holes lose their energy and evaporate, Plus some theories put
the whole universe as the inverse of black holeness, a black
hole turned inside out. Its all those extra theoretical dimensions that
does it.

Flip open one of these and you get a triangle shaped object but with one side (the side you use to fan your face) curved. Opposite the curved side you have a hinge.
We see things on the curved side. There looks to be space between points, and photons seem to take time to traverse the distance between points.
The real photon lives at the hinge and doesn't go anywhere at all, what we see is just a projection of the photon turning. There's only one photon here.
The curved side of the Japanese fan represents what we see as spacetime, which unfolded at the Big Bang and the hinge (and the radial section, it's just a model) represent the other dimensions which have remained "curled up small" according to Superstring Theory.
I like this model, for one reason it accords a reason for a "thought experiment" postulated by Einstein (and since experimentally confirmed) that from the point of view of a photon, it would take zero time to move from one end of the universe to the other. That's because the photon doesn't actually go anywhere, in this model, it just turns. What we see is a shadow racing by at a high speed, a shadow of the underlying reality.
Of course, all this is just brouhaha, the really big question is why is there anything at all?
