‚The Youngness Paradox‘ –„Why SETI has Not Found Any Signals from Extraterrestrial Civilizations”
According to MIT’s Alan Guth , originator of the inflationary universe theory, our Universe is a product of eternal inflation –eternal into the future, but not into the past. An eternally inflating Universe produces an infinite number of pocket universes , which in turn are producing more new universes. The old, mature universes are vastly outnumbered by universes that have just barely begun to evolve. Guth called it the „Youngness Paradox.“
Guth says that „the synchronous gauge probability distribution strongly implies that there is no civilization in the visible Universe more advanced than us. We would conclude, therefore, that it is extraordinarily improbable that there is a civilization in our pocket Universe that is at least one second more advanced than we are. Perhaps this argument explains why SETI has not found any signals from alien civilizations.”In Guth’s view, “nature gets a lot of tries — the Universe is an experiment that’s repeated over and over again, each time with slightly different physical laws, or even vastly different physical laws,” says MIT physics professor Robert Jaffe.
