    科学家们现在认为也许真的存在平行宇宙-事实上,可能存在无限多的平行宇宙,而我们恰好生活在其中的一个.其它的那些宇宙包含了空间,时间以及稀奇百怪的另类的物质.其中的某些可能包括了你,以一个略为不同的形式出现. 令人吃惊的是,科学家们认为这些平行宇宙距离我们还不到1毫米.事实上,我们的引力只是另一个宇宙泄漏到我们这个宇宙微弱的信号.
    Scientists now believe there may really be a parallel universe - in fact, there may be an infinite number of parallel universes, and we just happen to live in one of them. These other universes contain space, time and strange forms of exotic matter. Some of them may even contain you, in a slightly different form. Astonishingly, scientists believe that these parallel universes exist less than one millimetre away from us. In fact, our gravity is just a weak signal leaking out of another universe into ours.
    The same but different
    For years parallel universes were a staple of the Twilight Zone. Science fiction writers loved to speculate on the possible other universes which might exist. In one, they said, Elvis Presley might still be alive or in another the British Empire might still be going strong. Serious scientists dismissed all this speculation as absurd. But now it seems the speculation wasn t absurd enough. Parallel universes really do exist and they are much stranger than even the science fiction writers dared to imagine.
    Greater dimensions
    It all started when superstring theory, hyperspace and dark matter made physicists realise that the three dimensions we thought described the Universe weren t enough. There are actually 11 dimensions. By the time they had finished they d come to the conclusion that our Universe is just one bubble among an infinite number of membranous bubbles which ripple as they wobble through the eleventh dimension.
    A creative touch
    Now imagine what might happen if two such bubble universes touched. Neil Turok from Cambridge, Burt Ovrut from the University of Pennsylvania and Paul Steinhardt from Princeton believe that has happened. The result? A very big bang indeed and a new universe was born - our Universe. The idea has shocked the scientific community; it turns the conventional Big Bang theory on its head. It may well be that the Big Bang wasn t really the beginning of everything after all. Time and space all existed before it. In fact Big Bangs may happen all the time.
    Of course this extraordinary story about the origin of our Universe has one alarming implication. If a collision started our Universe, could it happen again? Anything is possible in this extra-dimensional cosmos. Perhaps out there in space there is another universe heading directly towards us - it may only be a matter of time before we collide.
