Physics and consciousness.

Sometimes, when we open the net, we can read about things, like the intelligent universe and the quantum origin of consciousness. The last one is a sometimes misunderstood version of quantum calculations, where large neuron groups take part in some action. That means the brains use quantum calculations, but that is not about physics. 

The quantum calculation means that the system shares the mission with multiple subsystems. In human brains, neurons are the subsystems that send information between three layers. So, we can say that the brain cells and neurons play ping-pong with data or information. The diencephalon selects information that brains, or we think we need later. But that doesn't mean that this thing has something to do with physics. 

In human brains, neurons send information between each other using axons. Axons load information into the neurotransmitters that act as the chemical qubits. There is the possibility to create a system that mimics human brains by using advanced computers. The artificial neuron could be the ball that the microchip controls. Data travels between those balls through artificial axons. 

The axons can involve multiple quantum channels like nanotubes or optic fibers. When those quantum channels send data to each other, that system acts like a quantum computer. The number of activated quantum channels determines the state of the qubit. 

But then we can go to the imagination or idea of the intelligent cosmic structure. The idea is taken from Isaac Asimov's short novel "The Last Question" and the fictional supercomputer called "Multivac", which some people sometimes translate to "Multiple vacuums". That causes the idea that the qubits can be multiple internal false-vacuums or voids, and the void channels the wormholes can connect those things together. 

Those vacuums would form a bubble-shaped structure where internal electromagnetic fields control and route information. One of those models is the theoretical black hole network where the plasma bubbles around black holes form a quantum-computer-style system. And black hole's relativistic jets transport information between them. 

The idea is to form a model where gravitation can form intelligent structures. And of course, the intelligent universe theory creates the model where the entire universe acts like a giant computer, and we are part of that computer's thoughts or simulations. That is the so-called radical and expanded model of the Multivac. There are mysterious structures in the universe that we cannot just leave without notice. But the argument against the "Universe is a simulation" is "Who made that simulation, and what is that person's motive". 

In some SciFi novels, the simulated universe is created for training space travelers while they sleep in the cryostatic sleeping on space trips that take millenniums. In some models, those creatures would travel in interstellar space in the form of neurons. When the craft goes to the long-distance one-way space trip that crew dies. The system copies their memories and other things to artificial neurons. Those neurons can be clones of the traveler's neurons. Then the system loads those neurons into the culture medium. The system can create two or three neuron groups and when the last neuron group turns old system transfers the data from them into the next culture. 

When the craft arrives into Destiny the travelers will get their bodies back. The highly advanced biotechnology makes it possible to change DNA from the cell's nucleus. That allows the user to create the copy of the traveler. Then that traveler requires training and in that case, the system can use simulated reality and metaverse along with neuro-implants. Maybe that thing is possible in the future. 

Galaxies and galaxy clusters are part of the giant superstructure called "the cosmic web", or "cosmic neural network", because those structures look like the neural network. There are also giant plasma flows between galaxies and galaxy clusters. That thing formed a model where artificial neurons could be the plasma ball. 

The ball's shell controls the ion flow that travels in those tubes between the balls. The ions that travel in that ion flow are the neurotransmitters. The artificial axon is a bunch of quantum channels. By adjusting the position of the electric-, or magnetic points on the ball the system can adjust the ion flow and aim it into the right tube or ion channel. The microchip can control this system with a very high accuracy.
