Prepare to feel very claustrophobic. My several recent blogs, detail unique black hole collision scenarios, to reprise these, when three black holes collide in linear formation, they form a larger black hole.
When three black holes collide in triangular configuration, each black hole sacrifices a sector of its event horizon, whch becomes an internal event horizon. An Internal External Event Horizon Continuum forms. This is the event horizon of a Black Torus. A characteristic of the continuum, is that nothing can leave the external event horizon, and nothing can enter the internal event horizon. However,
as the torus continues to morph to gravitational equilibrium, the internal event horizon ` sectors ` (like the inside of an motor tyre inner tube) begin to interfere with opposite sectors, and the internal event horizon, ceases to be gravitationally closed. Core collapse then initiates jetting.
The three Black Holes first "morphed " into a Torus, and then morpedd into a Jetting Torus. Or
a Jetting Black Toroidal Object. Consider other Non Triangular collisions of Black Holes. A stream of Black Holes ( quite possible, see Google / Warren Brown. Hypervelocity Stars Harvard cfa ), in close proximity, possess the capability to link up into spherical configuration,, and form a Black Shell.. A Hollow Black Hole, that would actually ` float` in a sufficiently densse fluid.
This is a very interesting object. The interior of the Black Shell would become a super absolute vacuum, with the perfectly spherical internal event horizon, forever endeavouring to tear the hollow shell apart.
Our Universe could actually exist within a massive Black Shell, which could be expanding inner space, which we would observe as repulsive dark energy.
