Multiverse: have astronomers found evidence of parallel universes? | Science | The Guardian
They call it the multiverse. It’s a cosmos in which there are multiple universes. And by multiple, I mean an infinite number. These uncountable realms sit side by side in higher dimensions that our senses are incapable of perceiving directly.
Yet increasingly astronomers and cosmologists seem to be invoking the multiverse to explain puzzling observations.
The stakes are high. Each alternate universe carries its own different version of reality. There will be one where you wrote this column and I read it; one where the Guardian is an alt-right propaganda rag; even a really weird one in which Donald Trump uses twitter to spread nothing but amusing cat videos.
It sounds bonkers but the latest piece of evidence that could favour a multiverse comes from the UK’s Royal Astronomical Society. They recently published a study on the so-called ‘cold spot’. This is a particularly cool patch of space seen in the radiation produced by the formation of the Universe more than 13 billion years ago.
