Universe Grows Like a Giant Brain

by Tia Ghose

The universe may grow like a giant brain, according to a new computer simulation.

The results, published Nov.16 in the journal Nature’s Scientific Reports, suggest that some undiscovered, fundamental laws may govern the growth of systems large and small, from the electrical firing between brain cells and growth of social networks to the expansion of galaxies.

“Natural growth dynamics are the same for different real networks, like the Internet or the brain or social networks,” said study co-author Dmitri Krioukov, a physicist at the University of California San Diego.

The new study suggests a single fundamental law of nature may govern these networks, said physicist Kevin Bassler of the University of Houston, who was not involved in the study.

Using Einstein’s equations of relativity, which explain how matter warps the fabric of space-time, physicists can retrace the universe’s explosive birth in the Big Bang roughly 14 billion years ago and how it has expanded outward in the eons since…
