Our Universe at Home Within a Larger Universe?

[n2doc]

ScienceDaily (Apr. 7, 2010) — Could our universe be located within the interior of a wormhole which itself is part of a black hole that lies within a much larger universe?

Such a scenario in which the universe is born from inside a wormhole (also called an Einstein-Rosen Bridge) is suggested in a paper from Indiana University theoretical physicist Nikodem Poplawski in Physics Letters B. The final version of the paper was available online March 29 and will be published in the journal edition April 12.

Poplawski takes advantage of the Euclidean-based coordinate system called isotropic coordinates to describe the gravitational field of a black hole and to model the radial geodesic motion of a massive particle into a black hole.

In studying the radial motion through the event horizon (a black hole's boundary) of two different types of black holes -- Schwarzschild and Einstein-Rosen, both of which are mathematically legitimate solutions of general relativity -- Poplawski admits that only experiment or observation can reveal the motion of a particle falling into an actual black hole. But he also notes that since observers can only see the outside of the black hole, the interior cannot be observed unless an observer enters or resides within.

I think the Universe will turn out to be shaped like a turtle....

1. Sure, anythings possible,

and I like Einstein, Rosen, and Indiana University.

10. All you have to do is put a "?" at the end of the sentence

and antything is possible.

2. Yup. It's turtles all the way down.

3. I love this stuff

I scarcely understand a single word, but I find it both comforting and liberating to contemplate the vastness, strangeness, wonder of it all.

My own "theory" (lol) since I first learned about matter disappearing into black holes has been that OUR universe is the end result of all the matter disappearing into a black hole in ANOTHER universe.

hey, at least it's more intelligent than thinking that the earth is 6,000 years old!

supported on the backs of four elephants. The opening scene from "Hogfather" was an excellent representation.

Either way, it's got to be far more bizarre than anything mere humans could imagine.

6. self-simularity on different scales...

Chaos theory predicts this.

7. I love this stuff you post, but I'm so truly ignorant. Pathetic, actually

I keep thinking of "Horton Hears a Who". Well, don't give up - keep tryin' to edumicate me:) Thanks.

9. Somehow I suspect that if I fell into a black hole,

I'd suffocate as my ship got torn apart, then spiral inward until my atoms got crushed.

Yeah, I'm a buzzkill.
