Universe Grows Like a Giant Brain

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.
A fundamental law of nature may govern the growth of brain networks, social networks, and the expansion of the Universe, a new computer simulation suggests.
"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.
"At first blush they seem to be quite different systems, the question is, is there some kind of controlling laws can describe them?" he told LiveScience.
By raising this question, "their work really makes a pretty important contribution," he said.
Past studies showed brain circuits and the Internet look a lot alike. But despite finding this functional similarity, nobody had developed equations to perfectly predict how computer networks, brain circuits or social networks grow over time, Krioukov said.
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.
So Krioukov’s team wondered whether the universe’s accelerating growth could provide insight into the ways social networks or brain circuits expand.
Brain cells and galaxies
The team created a computer simulation that broke the early universe into the tiniest possible units — quanta of space-time more miniscule than subatomic particles. The simulation linked any quanta, or nodes in a massive celestial network, that were causally related. (Nothing travels faster than light, so if a person hits a baseball on Earth, the ripple effects of that event could never reach an alien in a distant galaxy in a reasonable amount of time, meaning those two regions of space-time aren’t causally related.)

Youth gang riots in the Swedish capital Stockholm have entered fifth straight night. Hundreds of mostly immigrant teenagers tore through the suburbs, smashing windows and burning cars in the country’s worst outbreak of violence in years.
At least six vehicles were torched throughout the city late on Thursday while the police called for reinforcements from other Swedish cities bracing for further ...
The Ata ’Alien’ Humanoid May Have An Earthling Cousin

When a new documentary promised to unveil DNA tests on a 6-inch-tall humanoid found 10 years ago in Chile, everyone weighed in with an opinion.
UFO researchers hoped this might finally be proof of alien visitations. Skeptics were sure it was nothing more than shameless movie promotion.
The latest ripple in this controversy might be the most bizarre turn yet.
And by "ripple," ...

Deadly Drug Trials: Western Firms Bribed East German Doctors
2013 05 24
It wasn’t just the East German government that benefited from risky patient drug trials commissioned by Western pharmaceutical manufacturers decades ago. These companies also sent liaisons with lavish gifts to bribe and influence doctors to participate.
The presents always came in the springtime. When the representatives of Western pharmaceutical companies arrived at the Leipzig Trade Fair, they made sure that East ...
Home Secretary secretly strips two more people of British citizenship
2013 05 24
The Home Secretary has stripped at least two additional individuals of their British citizenship in recent months, the Bureau has learned.
In February, an investigation by the Bureau and published with the Independent revealed that Theresa May had signed deprivation of citizenship orders for 16 people between the 2010 election and November 2012, including five British-born individuals. That total has now ...
