John Brockman, writer, publisher and events manager for the science elite, has asked a hundred researchers the question, What do you believe is true even though you cannot prove it? The answers are posted at his e-magazine Edge (www.edge.org), and they exert an unquestionable morbid fascination—those are the very ideas that scientists cannot confess in their technical papers.
Since the Big Bang, matter has been busy organizing itself on particles, atoms, stars, planets, organic compounds and (on Earth at least) bacteria, animals and conscious brains. That is what scientists think proved. But their unproven beliefs tell another story, or thousand others.
“I doubt that the Big Bang is the beginning of time, I strongly suspect that our history extends backwards before that”, writes in Edge Lee Smolin, theoretical physicist. He cannot prove it, but he believes it. As his colleague Lawrence Krauss believes, without proofs too, that “there are likely to be a large, and possibly infinite number of other universes out there, some of which may be experiencing Big Bangs at the current moment”.
