We often speak of the universe being a reflection of ourselves and point to how the eye, veins, and brain cells mirror visual phenomenon in the natural universe. As above so below right? Well, check this out.
How about the idea that the universe is a giant brain? 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.
It also revealed that the human brain is based on a network of more than 69 billion neurons. The universe, for example, has at least 100 billion galaxies. The researchers compared the proportion of neurons in the brain and clusters of stars in the Universe and found that they account for about 30 percent of the mass of all systems.
The remaining 70 percent are components that have inactive but important functionality. For example, in the brain it is water, while in the Universe it is dark energy.
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.
When the team compared the universe’s history with growth of social networks and brain circuits, they found all the networks expanded in similar ways: They balanced links between similar nodes with ones that already had many connections.
For instance, a cat lover surfing the Internet may visit mega-sites such as Google or Yahoo, but will also browse cat fancier websites or YouTube kitten videos. In the same way, neighboring brain cells like to connect, but neurons also link to such “Google brain cells” that are hooked up to loads of other brain cells.
“The new study suggests a single fundamental law of nature may govern these networks”, said physicist Kevin Bassler of the University of Houston.
“For a physicist, it’s an immediate signal that there is some missing understanding of how nature works,” says Dmitri Krioukov from the University of California San Diego.
As summarized by the original study: “Here we show that the causal network representing the large-scale structure of spacetime in our accelerating universe is a power-law graph with strong clustering, similar to many complex networks such as the Internet, social, or biological networks.
We prove that this structural similarity is a consequence of the asymptotic equivalence between the large-scale growth dynamics of complex networks and causal networks.”
So this may seem weird, but let’s think about this. Scientists always talk about consciousness being the underlying fabric of the universe from which all things emerge (M-theory, string theory, Unified Field Theory, etc. see the work of Dr. Amit Goswami and Dr. John Hagelin).
So not only is the fabric of the universe conscious like a brain, it is growing like a brain as well. But here’s a question…a brain to what?
Is it possible we exist as a thought within the mind of some Super Intelligence? Are we just brain cells operating within a Cosmic Mind? Maybe, maybe not, but it’s fascinating to think about.
