Aug. 3, 2011 — The theory that our universe is contained inside a bubble, and that multiple alternative universes exist inside their own bubbles -- making up the 'multiverse' -- is, for the first time, being tested by physicists.
Is our universe inside a bubble? First observational test of the 'multiverse'
Sometimes what you see and what you perceive aren't at all what they seem. That is the message of acclaimed physicist Brian Greene's new television series. In "The Fabric of the Cosmos," a four-hour NOVA series, Greene takes viewers on a mind-bending journey to the frontiers of modern physics, where theories of space, time and the universe are challenging scientists to re-think everyday perceptions.

You might think it’s hard to have a conversation with theoretical physicist Brian Greene. His research specialty is superstring theory, the hypothesis that everything in the universe is made up of miniscule, vibrating strands of energy.

Brian Greene: A Physicist Explains 'The Hidden Reality' Of Parallel Universes
The multiverse (or meta-universe ) is the hypothetical set of multiple possible universes (including the historical universe we consistently experience) that together comprise everything that exists and can exist: the entirety of space , time , matter , and energy as well as the physical laws and constants that describe them. The term was coined in 1895 by the American philosopher and psychologist William James . [ 1 ] The various universes within the multiverse are sometimes called parallel universes . The structure of the multiverse, the nature of each universe within it and the relationship between the various constituent universes, depend on the specific multiverse hypothesis considered.

Science's Alternative to an Intelligent Creator: the Multiverse Theory | Cosmology
Prove It Linde’s recent research has helped solidify the connection between string theory and the multiverse. Some physicists have long embraced the notion that the extra dimensions of string theory play a key role in shaping the properties of new universes spawned during eternal chaotic inflation. When a new universe sprouts from its parent, the concept goes, only three of the dimensions of space predicted by string theory will inflate into large, full-blown, inhabitable spaces.
Jan. 13, 2010 — Is there anybody out there? In Alejandro Jenkins' case, the question refers not to whether life exists elsewhere in the universe, but whether it exists in other universes outside of our own.
