Does Every Black Hole Contain Another Universe?

Like part of a cosmic Russian doll, our universe may be nested inside a black hole that is itself part of a larger universe.

In turn, all the black holes found so far in our universe—from the microscopic to the supermassive—may be doorways into alternate realities.

The idea that black holes may be worm holes to other universes isn't new. However, in a recent paper published in the journal Physics Letters B, Indiana University physicist Nikodem Poplawski presents new mathematical models that describe how wormholes are viable alternatives to the "space-time singularities" that Albert Einstein predicted to be at the centers of black holes.

Decoding Reality: The Universe is a Quantum Computer

Seth Lloyd reviews Vlatko Vedral's new book Decoding Reality, which asserts that everything is at its most fundamental quantum information, and the universe is a quantum computer.

Mysterious Cosmic 'Dark Flow' Tracked Deeper into Universe

The dark flow is controversial because the distribution of matter in the observed universe cannot account for it. Its existence suggests that some structure beyond the visible universe -- outside our "horizon" -- is pulling on matter in our vicinity.

Our Universe as a Hologram?

New Scientists Article

For many months, the GEO600 team-members had been scratching their heads over inexplicable noise that is plaguing their giant detector. Then, out of the blue, a researcher approached them with an explanation. In fact, he had even predicted the noise before he knew they were detecting it. According to Craig Hogan, a physicist at the Fermilab particle physics lab in Batavia, Illinois, GEO600 has stumbled upon the fundamental limit of space-time - the point where space-time stops behaving like the smooth continuum Einstein described and instead dissolves into "grains", just as a newspaper photograph dissolves into dots as you zoom in. "It looks like GEO600 is being buffeted by the microscopic quantum convulsions of space-time," says Hogan.

If this doesn't blow your socks off, then Hogan, who has just been appointed director of Fermilab's Center for Particle Astrophysics, has an even bigger shock in store: "If the GEO600 result is what I suspect it is, then we are all living in a giant cosmic hologram."

Sean Carroll's Theory of Time

This is an interesting idea from Sean Carroll. In a virtually empty universe there is no causality, and therefore no clear direction of time. Just random fluctuations.
From these fluctuations new universes are born.

Science's Alternative to an Intelligent Creator: the Multiverse Theory

This December '08 article from Discover magazine summarizes why the fine tuning for life of our observable universe suggests a large multiverse...or a designer.

Of course, multiverses would likely lead to intelligence capable of creation on a universal scale, raising the question of whether there is any clean way to completely remove a role for intelligence in an explanation of reality.
