Hidden passage???

Physicists conceptualize black holes spin at almost the speed of light. With this being said, it stands to reason that the extreme inertia generated by such spin rates could transform black holes into wormholes, a notion being seriously studied by researchers checking out the supermassive black hole residing in our Milky Way galaxy.

Wormholes are a controversial topic in physics, to say the least. Not only is the idea of traveling through these theoretical passageways between two disparate regions of spacetime debatable, but their very existence is unclear. A forthcoming paper, however, suggests a method to look for a wormhole inside a black hole—and those observations could occur within a decade.

Seems BRT's take on black holes possibly being wormholes is not too far fetched after all. :)

We live in interesting times.
