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?

Eh, same with any cosmological theory. Give me some data that the currently accepted model doesn't explain and I'll listen.

The fact that the Universe is expanding gives it black hole properties. Imagine your 1 ly outside the edge and you look back. You would see the Universe rushing twords you (or you twords it) and you could never outrun it. No matter how far you hop the universe is expanding right behind you, engulfing you. And from your perspective, your always being "pulled" back in. No escape unless its to the 5th dimension, and even if that exists and it is possible, there is no way to determine if the Universe is expanding or contracting in said dimension.

And just imagine, the combined mass of every black hole, star, planet. EVERYTHING...........your ship couldnt possibly escape the gravity of the Universe. And from the outside, your ship would see it all as one big mass. You try and try and try to accelerate away, but no matter how fast you go, no matter which way you go, the gravity of the Universe curves you back twords it. Like the frame dragging effect of a black hole. No matter how fast you go, space itself is warped around the hole causing all directions to fall back into the hole. So Accelerating to warp 2 just gets you to the singularity faster.

But would this combined mass emit light? At least as seen from the outside? From what I understand, the answer would have to be no. If the Universe "contains" ALL light, then none should be able to escape. It cant, because its contained. This "should" make the Universe VERY dark unless you were inside it.

People into string theory must be loving this. What other force than a black hole can possess the raw power to fold dimensions?

Basically, as long as it dies in the end, the overall math works, and you end with what you start. 0+0=0
Even if its 0=1-1+1-1+1+1+1-1-1-1+1+1+1-1-1-1+1+1+1+1=0

As far as a "white" hole, perhaps this is what waits for us on the other side of the "dark flow"

Its all very interesting, but my main question(S)are these.

If space were a fixed sheet, and you contracted one piece of it, would not another piece "stretch" or appear to "expand"? Would it not be forced to? How far can this fabric stretch before tearing? How thin? 1 quark? 2.....

If you take a bedsheet and spread it out over your bed, and then crumple a little ball of bedsheet right in the center, are not the edges pulled in twords the center as well? Perhaps "dark flow" is the secret to expansion. Without it, "space" has no expanding force. If the bedsheet were rubber, and the edges fastened down, the sheet would "expand" at all points except one. And the one point is the area where you are crumpling the sheet. This point would be an "intersection" point where all space and time would be compacting.

The problem with this hypothesis is that ALL points should be contracting to this one.

But.......when you think about expansion, the human mind tries to visually see it as one point. A singularity if you will, where all space time expanded from. Yet when you conceptualize it, all points expanded from all other points at the same time.

So what happens if we flip it around? All points contracting on all points at the same time? The universe would shrink back down to a much smaller neighborhood.

If "Dark Flow" is bound by gravity, then shouldn't the adding of galaxies IN the flow increase the overall mass of the flow itself? In other words, shouldn't it become more massive, aka more gravity, aka more galaxies, aka more dark flow?

And why isn't it universal? Why can we only observe it in ONE section of the CMB? Like its one point, counterpointing another (big bang?) Why do clusters closer to home not have these properties? And where is all the matter going once it enters this "dark flow"?

0=1-1=0 perhaps?

Or is there a cosmic "vacuum cleaner" in orbit around the visible Universe?

What is confining it to ONE section? And why is it required that it be so far away? Why do we not have other "dark flows" closer to home? What is so special about THAT particular section of space where this CAN exist, verses the space where WE exist?
