The existence of parallel universes may seem like something cooked up by science fiction writers, with little relevance to modern theoretical physics. But the idea that we live in a “multiverse” made up of an infinite number of parallel universes has long been considered a scientific possibility – although it is still a matter of vigorous debate among physicists. The race is now on to find a way to test the theory, including searching the sky for signs of collisions with other universes.

It is important to keep in mind that the multiverse view is not actually a theory, it is rather a consequence of our current understanding of theoretical physics. This distinction is crucial. We have not waved our hands and said: “Let there be a multiverse”. Instead the idea that the universe is perhaps one of infinitely many is derived from current theories like quantum mechanics and string theory.

The universes predicted by string theory and inflation live in the same physical space (unlike the many universes of quantum mechanics which live in a mathematical space), they can overlap or collide. Indeed, they inevitably must collide, leaving possible signatures in the cosmic sky which we can try to search for.

Whether we will ever be able to prove their existence is hard to predict. But given the massive implications of such a finding it should definitely be worth the search.

    "Maths" is the preferred abbreviation for mathematics in the UK.

    Doesn't make it correct though.

        They also add u's to words that don't need them. What do you think British people can't speak poor English?

          At least we know how to use punctuation.

        But the American abbreviation is actually older then the British abbreviation. In fact how many other abbreviations can you name that remove the middle of the word and not the end of the word. I can't really think of any others.

          I spent way too long trying to think of more.

    It's the self-esteem movement in America. "I'm no good at math" sounds like the speaker is only bad at one thing.

    BUT "I'm no good at maths" could be an admission of being bad at as many as 7 things.
