Stephen Hawking supports the concept that BH’s are gateways to other universes. Not only do I think this is an unnecessary addition to BH characteristics I think it contradicts Stephen Hawkings theory that information that enters a BH remains as a feature of the EH.

Why should BH’s consist of anything more than an EH, essentially existing as an eddie in space time? If infalling matter can never reach the core does there have to be a core at all?

ie; why should the collapse event that initiates the BH ever actually equilibrate as a mass? From our external perspective time within the BH is at a relative standstill and has been that way since the point of collapse, not after.

If they were gateways to other universes wouldn’t that mean any matter/energy falling into them is lost?
If so then wouldn’t we need a whitehole to put the same amount of energy back into our universe from another one.

I wonder if you could out-accelerate spaghettification? Would a craft that could generate sufficient length contraction remain intact if accelerated ‘through’ the BH?

I think it could but you would come out at the end of the universe not another one.

I think the only simple option to this would still rule out a multiverse. In this scenario you might exit into an antimatter universe. I think this would have to involve the foreshortening of the craft reaching a point in which it’s matter reverse to an antimatter state as transitional mechanism.

When it comes to understanding black holes as expressed in general relativity, it’s all in the coordinate system adopted.

In Eddington coordinates, an object approaching an EH takes an infinite amount of time to get there. But that’s only from the viewpoint of somebody outside the black hole. To the in-falling object itself, it takes a finite amount of time to pass the event horizon and a finite amount of time from there to the singularity in the centre.

In Kruskal–Szekeres coordinates, every black hole has two outsides that cannot communicate with one another, so acts as a bridge between two universes. In addition, every black hole has its companion white hole, so everything crushed into nothingness at the singularity re-emerges from a white hole on the other side.

In Penrose coordinates, a single black hole can link an infinite number of universes. Passage from universe to universe can occur by passing through the black hole as with Kruskal–Szekeres – or by passing through barriers of infinite time.

But things really get interesting when you go beyond general relativity to, for example, string theory.

It simply reinforces the EH. There is no “in”.

That’s an easy one. It goes into an object of infinite density.

The more difficult question is “if a black hole has no hair then where does all the information inherent in the infalling matter and energy go”. And the answer has to be that it stops at the event horizon.
