The universe can be part of a large quantum computer

The universe can be part of a large quantum computer 86

Recently, two physicists from the Baltic Federal University Immanuel Kant (IKBFU) in Russia have proposed a whole new view of the cosmos. Their research catches the crazy idea that we are living a simulation in computer and mixing it with the astonishing “many worlds” theory to say that essentially our entire universe is part of an immensely large quantum system encompassing “countless” Multiverses.

The universe could be part of a large quantum computer, say Russian scientists

When you think of quantum systems, such as the quantum computers of IBM and Google, we usually imagine a device designed to work with subatomic particles – qubits – to perform quantum calculations.

These computers may one day perform advanced calculations that classical computers today cannot, but for the time being they are useful as a way of researching the gap between classical and quantum reality.

Artyam Yurov and Valerian Yurov, the IKBFU researchers behind the study mentioned above, postulate that everything in the universe, including the universe itself, should be viewed as a quantum object. This means that to experience ‘quantum reality’, we don’t have to look at subatomic particles or qubits: we are already there. Everything is quantum!

Yurov and Yurov begin your job claiming that they turned upside down currently popular theoretical views of physics:

We present a new view on cosmology, based on the quantum model proposed by Michael and Hall. Following the idea of ​​this model, we consider finite many homogeneous and isotropic classical universes whose evolutions are determined by the standard Einstein-Friedmann equations, but which also interact with each other in quantum form.

The article goes on to describe mathematically how our entire universe is itself a quantum object. This means that, as a tiny subatomic particle, it exhibits quantum properties that must include overlap. Theoretically, our universe should be in more than one place or state at a time, and that means there must simply be something out there for it to interact with – even if it means that it uses non-intuitive quantum mechanics to interact with itself in multiple states simultaneously. .

The problem with expanding quantum mechanics to large objects – such as a single cell – is that other theoretical quantum characteristics stop making so much sense. In this case, decoherence, or how quantum objects collapse from various states to the physical state we see in our classical observations, does not appear to occur on the cosmic scale.

Yurov and Yurov have a simple solution to this: they state unequivocally in their work that ‘there is no’ decoherence ”.

According to an article by Sci-Tech Daily, the lead author of the article Artyom Yurov said:

At that time I was skeptical of the idea. Because it is known that the larger the object, the faster it collapses. Even a bacterium collapses extremely fast, and here we are talking about the universe. But here (Pedro Gonzales Diaz, a deceased theoretical physician whose work partially inspired this study) asked me, “What does the universe interact with?” And I answered nothing. There is nothing but the universe and there is nothing with which it can interact.

But the more Yurov and Yurov explored the “many interacting worlds” theory (MIW), which says that all quantum functions physically manifest themselves in alternate realities (the cat is dead in one world, alive in another and dancing Cha Cha in another, etc.), but they realized that not only does this make sense, but math and science seem to work better if you assume that everything, including the universe, has quantum characteristics.

According to study:

This implies that the reason why quantum phenomena are so fragile has nothing to do with a ‘collapse of a wave function’ (whatever that means) – indeed, an object such as a wave function is essential and can be completely avoided in MIW formalism. No, the existence of quantum phenomena depends solely on the mutual positions of neighboring “worlds” – when they are close enough, quantum potential is alive and kicking; when they depart, the quantum potential diminishes and the particles become effectively classic again.

The researchers then used their assumptions to come up with calculations that expand the “many worlds” theory to encompass multiple universes or multiverses. The great idea here is that if the universe is a quantum object, it must interact with something and that they are probably other universes.

But what research does not explain is why our universe and everything in it would exist as analogous to a single qubit on a gigantic quantum computer spanning multiple universes simultaneously. If humans are not the magical observers who cause the quantum universe to collapse into classical reality, by measuring it, we could be gears in the machine – perhaps the universe is a qubit, maybe we are the qubits. Perhaps we are just noises that the universes ignore as they perform their calculations.

Maybe we live in a computer simulation after all. But instead of being the “non-playable characters – NPCs”Favorites of an advanced creature, we are just a few pieces of math that help the operating system work.

Psilocybin mushrooms sprout in the blood of an ‘experimental’ patient

Psilocybin mushrooms sprout in the blood of an 'experimental' patient 99

US doctors described the story of a man who tried to relieve depression with psilocybin mushrooms in an unconventional way. He injected an intravenous infusion of mushrooms, causing the mushrooms to continue to multiply in his blood and cause multiple organ failure. The case was reported in the Journal of the Academy of Consultation-Liaison Psychiatry.

Many drugs that people traditionally use as psychedelics are increasingly becoming the focus of medical attention. Some of them have already been repurposed and started clinical trials: for example, micro-doses of LSD have proven to be at least safe in the case of Alzheimer’s disease, and psilocybin has helped patients with  migraines and  depression. Often in such experiments we are talking about microdosing – that is, the mass of the substance is not enough for a psychoactive effect.

The story of an American who decided to experiment on his own was described by doctors led by Curtis McKnight of Creighton University School of Medicine. According to relatives, the 30-year-old American suffered from bipolar disorder, but shortly before the incident stopped taking his prescribed medications and suffered from alternating states of mania and depression.

When he stumbled upon research on the potential benefits of psychedelics, he boiled psilocybin mushrooms and injected the filtered solution into his vein. A few days after this experiment, relatives found him in a lethargic state with jaundice, diarrhea and bloody vomiting and took him to the hospital.

Doctors discovered the patient had a problem with multiple organs at once: acute renal failure, liver damage, tachycardia, and low blood saturation and ionic imbalance. He was prescribed droppers to normalize the composition of the blood, vasoconstrictors to raise blood pressure, antibiotics and antifungal drugs. Despite this, he developed septic shock and DIC (excessive blood clotting) and needed plasmapheresis. Only eight days later he was discharged from the intensive care unit, and at the time of publication of the article he had already been in the hospital for 22 days.

In the patient’s blood tests, in addition to the Brevibacillus bacteria , there were also Psilocybe cubensis fungi  – the same ones from which he injected himself intravenously. Apparently, due to insufficient filtration of the solution, the fungi entered the bloodstream and multiplied there, causing intoxication and multiple organ failure.

The authors of the work note that this is not the first such case – at least in the 80s of the 20th century, doctors already described a patient with similar symptoms after an intravenous injection. Therefore, McKnight and coauthors warn their colleagues: since psychedelics are increasingly used as a medicine (at the end of 2020, they began to legalize it in the United States), it is important to remind patients of the inadmissibility of self-therapy. Intravenous administration can be dangerous – doctors still do not know if it has the same psychoactive effect as the classical methods of administration.

A part of a person’s essence accompanies him throughout his life: this is confirmed by a brain scan

A part of a person's essence accompanies him throughout his life: this is confirmed by a brain scan 101

A new method of scanning the human brain has produced amazing results. It turns out that in every person there is a certain part of his essence, which accompanies him all his life from the moment of birth to death.

Scientists believe that this is the core of a person’s self-awareness. It combines memories of the past with fleeting sensations of reality and provides a basis for anticipation of events in the future.

It turned out that a certain part of a person’s consciousness is consistent as they grow older and older.

For centuries, scientists and philosophers have been interested in the question: can this sense of “personal self” be stable throughout life? A new psychological study with the results of a brain scan made it possible to conclude that a certain part of a person’s consciousness really accompanies him throughout his life.

It is consistent as it gets older and older. Miguel Rubianes, a neuroscientist at the Complutense University of Madrid, says the aim of the study was to answer the question: Are we the same person throughout life? In combination with the results of other studies, scientists have concluded that there is a certain component that remains stable from birth to death.

The other part of consciousness remains susceptible to current changes. The scientists recognized independence as the basis of identity. And every time a person uses the word “I”, he means a thread that connects together all the events and experiences that have occurred in life.

Experience gained over the years changes a person, changes the components of his identity. Each case associated with personal experiences, a broken heart, a successful career step, expected or unexpected failure lead to the fact that a person compares himself to himself before and after these events. It is a neurological programming scheme that involves visual self-knowledge as an indicator of connection with your impressions of yourself.

This effect makes it possible to cope with memories and recognition of information when it is associated, for example, with one’s own photograph of an infant. Although this principle has a lot of evidence, scientists believe that the very mechanism of the brain involved in this remains a mystery.

This study was published in the journal Psychophysiology.
