Our Universe at Home Within a Larger Universe? So Suggests Physicist's Wormhole Research
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....
"This condition would be satisfied if our universe were the interior of a black hole existing in a bigger universe," he said. "Because Einstein's general theory of relativity does not choose a time orientation, if a black hole can form from the gravitational collapse of matter through an event horizon in the future then the reverse process is also possible. Such a process would describe an exploding white hole: matter emerging from an event horizon in the past, like the expanding universe."...
"From that it follows that our universe could have itself formed from inside a black hole existing inside another universe," he said...
While in pop culture, this sort of revelation may not be surprising, I think that those "in the know" would be very interested in such an idea. Popular science has successfully spread the idea of a Cyclical Universe which brings about the imagery of a Big Crunch. So, it's not too big a leap for most people to accept something that is similarly flavored. A lot of people would be willing to accept such a claim straight out of the box.
But, the true significance is much more than simply popular science quizzes.
So, what say you, oh geekly minds obsessed with space?
Is this interesting enough to be excited about or another cosmological idea that doesn't have a chance of being proven to be true?
