Could Our 3 Dimensional Universe Have Arisen From A 4 Dimensional Black Hole?

I am amazed that such a concept is being discussed in Forbes. Astrophysics/Astromathematics at this scale gets so mind blowingly strange. 90% of it starts to sound like a dream you have while under the influence of some hallucinogen.

Siegel does a lot of this kind of stuff at Forbes... and many of his articles focus on less conceptual stuff than this, but he's really good actually.

The reason I liked this piece, from my layman's knowledge of Cosmology, is that he talks about in terms of another dimension.

Theories that propose the idea of our Universe being sourced out of a black hole typically make it sound simpler... just one Universe birthing another, but the "twist" of adding another dimension to the "Mommy" black hole answers a question I always had... "how can ONE black hole from another Universe give birth to an entire Universe whose 'information' is so vast that trillions of black holes (and galaxies) result from it?"

If one considers the possibility of a fourth dimensional black hole, that loss of information "problem" disappears (presumably). That's why it's so interesting that they refer to the event horizon as a two dimensional storer of information, i.e. it has a record of everything that gets sucked in, never to escape again and that a theoretical "map" of the interior of the black hole can be extrapolated. Just something I never thought about until I read this article.

Fun stuff... and, yes, "trippy" too, lol.

As if I needed another reason to use mind altering substances, there's also the discovery by Hubble that there are billions, er, trillions more galaxies that we previously thought. Also from Forbes
