Which is incredibly cool. But if an interpretation of the Holographic
Principle is true, then a black hole has no interior, just its event
horizon, where all the mass resides.

Or rather, its volume is indistinguishable from its surface, the event
horizon.

All area, no volume, just a 2D quantum screen. I am not sure, that this
would be any cooler. Thinner then air may still be cooler.
