Our Universe In A Wormhole Of A Bigger Universe?

Do you feel like you might be in a wormhole inside a black hole?

BLOOMINGTON, Ind. -- 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?

If this is true then we are isolated from a much larger universe. Do you feel the estrangement from the larger universe? Or the sense of abandonment? Maybe we were tossed into the black hole by some group in the larger universe just throwing out the trash.

On the bright side. we might all be standing on an Einstein-Rosen Bridge.

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.

If we could figure out how to get off the bleeding bridge we could step up into a far larger universe. Got that to look forward to.

dammit, that was the core plot element to a book I wanted to write - we discover a way to travel faster than light by "fixing" our reference frame to the Sun. Inadvertently, it turns out that what we've done is put ourselves in a "copy" universe inside a black hole. Which works out great, in terms of space exploration and discovery, until one of our colonies decides to fix the reference frame to their Sun, and they subsequently disappear from our universe.

The neat thing is that this concept would explain why we don't meet any aliens - they've all disappeared into their own black-hole universes.

Also, we could have been put into a black-hole universe for our own protection/restraint by some more-or-less benevolent super-beings - "oh look, complex life is evolving on this planet - lets create a black hole around their solar system so we don't have to worry about them eventually challenging us for supremacy over our universe".

Also, I find your last line fascinating: "If we could figure out how to get off the bleeding bridge we could step up into a far larger universe. Got that to look forward to"

Aren't human genetics amazing - we have an entire universe - 15 billion light years across - to explore and colonize, but the moment we discover that it's only part of the larger space, suddenly we're trying to figure out how we can escape from this small and confined place we're in.

No wonder the benevolent super-beings put us in this bubble universe!

Black hole or not may be our universe is part of a bigger one. But it is possible to find an other system of gravity than the one of the black hole, see at this address the articles 8 and 9 from october 9, 2009 :

A man climbs a mountain to ask a question of the Guru who lives in a cave near the top.

"Oh Great Guru" he says "Please tell me what holds the world up and keeps it from falling out of the heavens?"

The Guru tells him: "My son, the world rides on the back of a great elephant."

The man receives the answer and returns to his village to ponder it. A couple of weeks of sleepless nights later, he realizes that there is a problem in what the Guru had told him.

So, he climbs again mountain to ask the Guru another question.

"Oh Great Guru" he says "When I visited you a couple of weeks ago, you told me that the world rides on the back of a great elephant. But, I am not sure that my troubled mind is eased. Please tell me what holds up the great elephant that holds world up and keeps it from falling out of the heavens?"

The Guru tells him: "My son, the great elephant upon whose back the world rides, stands on the back of another great elephant."

The man receives the answer and returns to his village to ponder it. A couple of weeks of sleepless nights later, he realizes that there is still a problem in what the Guru had told him.

So, he climbs again mountain to ask the Guru yet another question.

"Oh Great Guru" he says "When I visited you a couple of months ago, you told me that the world rides on the back of a great elephant. Then a couple of weeks ago you told me that the great elephant that holds world up and keeps it from falling out of the heavens, stands on the back of another great elephant. But, Oh, Great Guru what does that elephant stand upon?"

The Guru calmly replied: "Yet another great elephant"

At this point the man became upset and greatly agitated.

The Guru, seeing his agitation and wishing to calm the man down so he could return to his village before nightfall, then said: "Yes my son, it is great elephants, elephants all the way down."

Suddenly, I feel claustrophobic.

To Fat Man : I knew this story but with a turtle :) .

Terry Pratchett new this story with 4 elephants and one large turtle. The discworld cosmologists even mounted an expedition to resolve the great science debate- is the turtle male or female.

Darren said at April 8, 2010 11:59 AM:

I knew this story with an elephant, two giraffes and a parrot.

Darren said at April 8, 2010 12:02 PM:

What is the airspeed velocity of an unladen swallow?

Fat Man said at April 9, 2010 12:32 PM:

Darren: What do you mean? An African or European swallow?

Cartesian: I like elephants.

Cartesian said at April 10, 2010 2:14 AM:

It depends but it is true that sometime it is better to have an elephant than a turtle at home (I mean in the garden) :) .

It was considered important to know, for disaster planning in the event they encountered another Diskworld, and nature took it's usual course...

Brett Bellmore said at April 10, 2010 4:37 AM:

Anyway, I'm reminded by this of Lovecraft's cosmology. Maybe our "brane" is the cosmological equivalent of a film of algae growing in an overlooked puddle, surviving only because it's beneath the notice of higher beings not so constrained. Jumping off the "bridge" might not be that smart a move if there are sharks in the water...
