In one of the episodes of the animated series "Rick and Morty" oneof the main characters, being abducted by aliens, gets into an ultra-high-tech computer simulation and does not notice it, continuing to do their usual things. But can something like this happen to us? Could it be that everything we see, feel, and hear is actually unreal? In 2003, Oxford University professor, Swedish philosopher Nick Bostrom wrote an article in which he argued that our world is a computer simulation. According to Bostrom, “if we live in a simulation, then the observable universe is just a tiny piece of what physically exists. Although the world that we see is in some sense 'real', it is not at the fundamental level of reality. " But is everything in our universe - from the smallest atom to the largest galaxy - nothing more than a computer project on the hard drive of some almighty being?
Yes, at first glance, an idea of realityhow about a computer simulation might sound ludicrous. But if you remember the achievements of mankind in the field of computer games, virtual reality and robotics (and some games today convey the visual and physical properties of our world so well), the question of whether we are not living in something like that no longer seems to be crazy.
In his seminal 2003 paper, NickBostrom first formulated the "modeling argument." Its essence lies in the fact that our reality is actually skillfully modeled and controlled using advanced computer technology. The Swedish philosopher suggested that advanced civilizations, possessing technologies with enormous computing power, can run computer simulations of their ancestors - that is, you and me - and, given the complexity of the technology, we will not know that our world is actually unreal.
It is also interesting that in just a fewFor decades, scientists have been able to develop devices capable of studying and simulating many of the basic characteristics of human intelligence. If computing power continues to grow along the existing trajectory, perhaps our descendants (or other intelligent life) can easily create a simulation of the universe.
Several prominent scientists and philosophers have expressedtheir support for modeling theory. Thus, in 2016, during the annual debate at the American Museum of Natural History (Isaac Asimov Memorial Debate), astrophysicist and popularizer of science Neil DeGrasse Tyson said that the chances of our universe being a simulated reality are 50/50... Tyson also pointed to a large gap inintelligence between chimpanzees and humans - and this despite the fact that our DNA coincides by 98%. Thus, a creature that is many times superior to us in terms of intellectual development can both exist and potentially create a simulation of our world.
Another argument for modeling theorycomes from the theoretical physicist James Gates of the University of Maryland, who studies matter at the level of quarks - the subatomic particles that make up protons and neutrons in the nuclei of atoms. According to the scientist, quarks obey rules that somewhat resemble computer codes that correct errors in data processing. However, how exactly these "correction codes", which in the real world help browsers work, ended up in the equations of quarks, electrons and supersymmetry remains a mystery.
This is interesting: Can the universe consciously imitate its own existence?
In turn, cosmologist Alan Guth fromThe Massachusetts Institute of Technology suggests that the universe can actually exist and at the same time be a laboratory experiment. According to his hypothesis, our world was created by a kind of superintelligence, similar to how biologists grow colonies of microorganisms in laboratories. In this case, the Universe, in which such an experiment would be carried out, would remain whole and intact. The new world would form in a separate space-time bubble that would quickly separate from the mother universe and lose contact with it.
Nevertheless, no matter how amazing and sometimes provocative theories the researchers put forward, it is almost impossible to prove that we are in the real universe, because any “proof” can be part of the program.
The nature of reality
Despite the solid philosophical and theoreticalarguments, some of which are outlined above, in 2017, a team of researchers at Oxford University found compelling evidence that our universe is more than a mobile app. Proof of? Attempts to simulate specific quantum phenomena, such as the Hall effect, are rapidly spiraling out of control - according to a paper published in the journal Science Advances, simulating just a few hundred electrons using the quantum method requires more atoms than there are in the universe.
But what happens if we assume that wedo we live in a simulation? Some experts suggest that as the program continues to run, problems will arise - so to speak, glitches in the matrix. According to The New Yorker, some philosophers, such as David Chalmers of New York University, suggest that more and more strange events in the "real" world may indicate that our universe is someone's simulation. Outside of the modeling of the universe, these events can represent diverging "points" in reality. Thus, every choice, no matter how small, can create its own universe.

And yet, while strange events andthe strangely ordered nature of fundamental mathematics suggests the possibility that our world is a computer simulation, with recent quantum research suggesting the universe is too complex to model. Do you think our reality is really a simulation or are there even more mind-blowing theories? We will wait for the answer here, as well as in the comments to this article.
