It's official, Elvis lives Last Updated: 12:01am GMT 16/01/2007 It might sound a little crazy, but our standard theories of cosmology and physics suggest that an infinite number of Presleys still exist, says Marcus Chown. And if that's not scary enough, it also means that you, and these words, are repeated ad infinitum across the universeElvis is alive. No, really! He didn't die of a cardiac arrest in his bathroom at Graceland on August 16, 1977. Instead, he slipped out of the back door under cover of darkness dressed as a nun, had a sex change and worked for several years...

Home About Edge Features Edge Editions Press Edge Search A striking consequence of the new picture of the world is that there should be an infinity of regions with histories absolutely identical to ours. That's right, scores of your duplicates are now reading copies of this article. They live on planets exactly like Earth, with all its mountains, cities, trees, and butterflies. There should also be regions where histories are somewhat different from ours, with all possible variations. For example, some readers will be pleased to know that there are infinitely many O-regions where Al Gore is the President...

Giant space-time ripples may cause cosmic expansion* 17:43 18 March 2005 * NewScientist.com news service * Maggie McKee Dark energy is not necessary to explain the accelerating expansion of the universe observed by astronomers, suggest controversial new calculations. Instead, gigantic ripples in space-time - larger than the observable universe - may be the cause. Astronomers have known since the 1920s that space itself has been expanding since the big bang about 14 billion years ago. But in 1998, they discovered the expansion must have sped up about a billion years ago, based on observations of supernovae that appeared farther away...

The Growth of Inflation Twenty-five years after Alan Guth turned cosmology on its head, what's the latest story of the universe's first moments? by Davide Castelvecchi Photo: Fred Ullrich It was a true Eureka moment if there ever was one. On the night of December 6, 1979, an obscure Stanford Linear Accelerator Center postdoc was up late, sweating over an even more obscure problem about particles called magnetic monopoles. Looking at his calculations the next day, the usually low-key Alan Guth annotated the words "SPECTACULAR REALIZATION" at the top of the page. Guth had discovered cosmic inflation, an idea which...

Cosmic Conundrum The universe seems uncannily well suited to the existence of life. Could that really be an accident?[snip]
