Our Universe at Home Within a Larger Universe? So Suggests Physicist's Wormhole Research

[helderheid]

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.

1. "...the interior cannot be observed unless an observer enters or resides within."

I nominate Sarah Palin.

3. !

:spray:

2. actually, our universe is inside a walnut

that is being gnawed at by a squirrel in another dimension, existing in a universe that is inside a sub-atomic particle making up part of a turtle in yet another overarching universe.

but from there, it's turtles all the way down.

[EOTE]

4. It can't be turtles ALL the way down.

Eventually one of those turtles has got to be sitting on a zebra or donkey or something.

[helderheid]

5. I thought it was a rabbit with a pancake on its head...

[EOTE]

10. Yes, at the bottom.

The zebra is standing on the pancake. And to the zebra, the pancake looks like a massive field of golden grain.

[ananda]

11. But they could be m o c k turtles..

.. sitting on a cheshire cat.

;-)

[FiveGoodMen]

12. You underestimate the power of turtles!

[tridim]

13. My question is, who is having sex with the last box turtle?

Santorum would usually get dibs, but unfortunately he's stuck in our Universe.

[Hissyspit]

24. The turtles are inside other turtles.

Or a zebra or a donkey or something.

6. So is this saying our "Big Bang" may have been the result of a black hole

forming in another larger universe?

This kind of stuff fascinates me, even as it makes my poor little brain hurt.

[helderheid]

7. It hurts my brain too. :)

[kimmerspixelated]

23. Ditto!!!

[helderheid]

27. BRAIN FREEZE... er... something!!

[tridim]

14. I think it would also mean our Universe is infinitely dense and infinitely small

Which is odd since our observations predict the exact opposite.

My guess is that we know about 1% of what will eventually be knowable.

[deutsey]

25. About the only thing we do know is that we don't know shit.

:hi:

[StClone]

8. But it's all made out of vibrating strings right?

[alfredo]

9. And that vibration say Om

[kestrel91316]

15. Our universe could be a single quark or boson. That would put a whole new

perspective on the question about how many angels could dance on the head of a pin........

kestrel's view of the universe: sort of a klein bottle or mobius strip setup, lol. Where smallest IS largest.

16. Wasn't this a stoned convo w/Donald Sutherland in Animal House?

[tridim]

18. Hehe, I just saw it the other day..

He actually said that one atom might be our entire "solar system", then he said the solar system is our "universe". Then I saw his ass.

Must have been bad Mexican brick weed.

[deutsey]

26. I thought the same thing!

:smoke:

17. Horton Hears a Who!

[MilesColtrane]

19. That would have to have been a gianormous, universe-sized black hole.

While this theory seems logical, since it's untestable, it's really more metaphysics than physics.

Since time itself started with the Big Bang, any theory about what happened before it will always be guesswork.

I personally think the Big Bang was preceded by the Big Foreplay.

[helderheid]

22. "the big foreplay"

:rofl:

[Odin2005]

20. Just a nitpick, but this is speculation, not "research".

Research requires actual observation and experiment.

[helderheid]

28. .

21. Semantics......it's all one thing.
