Does Non-Human Intelligence Manifest Itself To Us As Physical Laws?

nautil.us  |  A species can mitigate risk by spreading, decentralizing, and seeding as much real estate as possible. In this context, hyper-advanced life is going to look for ways to get rid of physical locality and to maximize redundancy and flexibility. The quantum realm offers good options. The cosmos is already packed with electromagnetic energy. Today, at any instant, about 400 photons of cosmic microwave radiation are streaming through any cubic centimeter of free space. They collectively have less energy than ordinary particles such as protons and electrons, but vastly outnumber them. That’s a lot of potential data carriers. Furthermore, we could imagine that these photons are cleverly quantum-mechanically entangled to help with error control.

By storing its essential data in photons, life could give itself a distributed backup system. And it could go further, manipulating new photons emitted by stars to dictate how they interact with matter. Fronts of electromagnetic radiation could be reaching across the cosmos to set in motion chains of interstellar or planetary chemistry with exquisite timing, exploiting wave interference and excitation energies in atoms and molecules. The science-fiction writer StanisÅ‚aw Lem put forward a similar idea, involving neutrinos rather than photons, in the novel His Master’s Voice.

That’s one way that life could disappear into ordinary physics. But even these ideas skirt the most disquieting extrapolations.

Toward the end of Carl Sagan’s 1985 science-fiction novel Contact, the protagonist follows the suggestion of an extraterrestrial to study transcendental numbers. After computing to 1020 places, she finds a clearly artificial message embedded in the digits of this fundamental number. In other words, part of the fabric of the universe is a product of intelligence or is perhaps even life itself.

It’s a great mind-bending twist for a book. Perhaps hyper-advanced life isn’t just external. Perhaps it’s already all around. It is embedded in what we perceive to be physics itself, from the root behavior of particles and fields to the phenomena of complexity and emergence.

In other words, life might not just be in the equations. It might be the equations.
