SUBSCRIBETHE SCIENCES3 Theories That Might Blow Up the Big BangTime may not have a beginning — and it might not exist at all.By Adam FrankMarch 25, 2008 10:30 AMBig Bang - NASA(Credit: NASA)NewsletterSign up for our email newsletter for the latest science newsSign up for the NewsletterEMAIL ADDRESSSIGN UPFor Paul Steinhardt and Neil Turok, the Big Bang ended on a summer day in 1999 in Cambridge, England. Sitting together at a conference they had organized, called “A School on Connecting Fundamental Physics and Cosmology,” the two physicists suddenly hit on the same idea. Maybe science was finally ready to tackle the mystery of what made the Big Bang go bang. And if so, then maybe science could also address one of the deepest questions of all: What came before the Big Bang?Steinhardt and Turok — working closely with a few like-minded colleagues — have now developed these insights into a thorough alternative to the prevailing, Genesis-like view of cosmology. According to the Big Bang THEORY, the WHOLE universe emerged during a single moment some 13.7 billion years ago. In the COMPETING theory, our universe generates and regenerates itself in an ENDLESS cycle of creation. The latest version of the cyclic model even matches key pieces of observational evidence SUPPORTING the older view.
