Technology has immortality, cures for the worlds devastating diseases, quantum computing and a host of other science fiction notions in its grasp. Current trends in a number of areas indicate that over the next 10 years many of these technologies will come to fruition. "The Next 10 Years" tracks the trends that will transform our everyday lives in almost unimaginable ways.

What Happened Before the Big Bang?

What Happened Before the Big Bang?

New discoveries about another universe whose collapse appears to have given birth to the one we live in today will be announced in the early on-line edition of the journal Nature Physics on 1 July 2007 and will be published in the August 2007 issue of the journal's print edition.

"My paper introduces a new mathematical model that we can use to derive new details about the properties of a quantum state as it travels through the Big Bounce, which replaces the classical idea of a Big Bang as the beginning of our universe," said Martin Bojowald, assistant professor of physics at Penn State. Bojowald's research also suggests that, although it is possible to learn about many properties of the earlier universe, we always will be uncertain about some of these properties because his calculations reveal a "cosmic forgetfulness" that results from the extreme quantum forces during the Big Bounce.
