The idea of the universe as a ‘giant brain’ has been proposed by scientists – and science fiction writers – for decades.
But now physicists say there may be some evidence that it’s actually true. In a sense.
According to a study published in Nature’s Scientific Reports, the universe may be growing in the same way as a giant brain – with the electrical firing between brain cells ‘mirrored’ by the shape of expanding galaxies.
The results of a computer simulation suggest that “natural growth dynamics” – the way that systems evolve – are the same for different kinds of networks – whether its the internet, the human brain or the universe as a whole.
A co-author of the study, Dmitri Krioukov from the University of California San Diego, said that while such systems appear very different, they have evolved in very similar ways.
The result, they argue, is that the universe really does grow like a brain.
