baby universe

A region of space–time that is connected to another region of space–time by a wormhole. It has been postulated that when a massive object in the Universe collapses to a black hole it could go through the singularity at the center of the black hole and create an expanding baby universe in another region of space–time. Inflation could allow such a baby universe to become large very rapidly. It may be the case that the Universe we live in originated in this way. Although the idea of baby universes is highly speculative and requires a theory of quantum gravity before it can be formulated definitively, it has been investigated by a number of theorists. See also multiverse.

Planck measured temperature differences in space, relics of variations in the matter density in the baby universe. Combined with other data and assumptions, those measurements can be used to deduce other properties of the cosmos.

According to Charles Lawrence, the NASA Planck project scientist at JPL, "Our previous images of the baby universe were like fuzzy snapshots.

Herschel and Planck on their way to unlock secrets of the Universe

The masters, like Hawking, relish the messy bits, the structure of space-time, the "no-boundary" concept, the baby universe. Larsen (physics and astronomy, Central Connecticut State U.) makes such messy bits, and Hawking's expertise in straightening them out, accessible to general readers and sets the concepts within the framework of Hawking's career and personal life.

This may give the best evidence of the existence of 10 or even 11 dimensional hyperspace.Every time a black hole forms, it may be creating a baby universe. The matter disappearing down a hole may, under certain circumstances, be blown 'out the other end,' creating a white hole in another twin universe.

Gardner, on his excited way to a black hole where a "baby universe" will shortly be hatched to house "a transhuman rapture," rhapsodizes about everything from the explosive formation of stars, planets, and "autocatalytic webs of complex carbon-based polymers" to string theory, wormholes, heat death, and "symbiogenesis."
