Physicists have long struggled to explain why the universe began conditionally suitable for the evolution of lifeWhy do the laws and constants of physics take on the very specific values ​​that allow the development of stars, planets, and ultimately life? It’s much weaker than it suggests, allowing matter to clump together rather than tear apart.

The common answer is that we live in an infinite multiverse of universes. universe Turned out to be ours. But the other is that our universe is a computer simulation, and someone (perhaps a highly alien species) is tweaking the conditions.

The latter option is supported by a scientific field called Information physics, which suggests that space-time and matter are not fundamental phenomena. Instead, physical reality is basically made up of bits of information, from which our experience of spacetime is born. By comparison, temperature “emerges” from the collective motion of atoms. A single atom essentially has no temperature.

This leads to the very possibility that our entire universe is actually a computer simulation. 1989, Legendary Physicist, John Archibald Wheeler, suggested that the universe is fundamentally mathematical and can be viewed as emerging from information. He coined the famous sayingfrom bit.”

2003, Philosopher Nick Bostrom from the University of Oxford, UK, simulation hypothesisThis shows that it’s actually very likely that we’re living in a simulation. That’s because advanced civilizations must reach a point where their technology is so sophisticated that the simulation becomes indistinguishable from reality, and participants are unaware that they are participating in the simulation. .

physicist Seth Lloyd A professor at the Massachusetts Institute of Technology in the United States says that the entire universe It could become a giant quantum computer.

And in 2016, business mogul Elon Musk concluded, “We are most likely in a simulation” (see video above).

empirical evidence

our physical reality It could be a simulated virtual reality rather than an objective world that exists independently of the observer.

The world of virtual reality is based on all information processingThis means that everything will eventually be digitized or pixelated to the smallest size (bit) that cannot be further subdivided. This appears to mimic our reality, according to the theories of quantum mechanics that govern the world of atoms and particles.it says it is smallest discrete unit energy, length and time. Similarly, the elementary particles that make up all visible matter in the universe are the smallest units of matter. Simply put, our world is pixelated.

The laws of physics that govern everything in the universe are also analogous to the lines of computer code that a simulation follows as a program runs. moreover, formulanumbers and Geometric pattern is ubiquitous, and the world appears entirely mathematical.

Another curiosity in physics that supports the simulation hypothesis is that maximum speed limit In our universe, it’s the speed of light. In virtual reality, this limit corresponds to a processor speed limit or processing power limit. Simulations have shown that when the processor is overloaded, the computer slows down. Similarly, Albert his Einstein’s theory of general relativity shows that time slows down near a black hole.

Perhaps the most supporting evidence for the simulation hypothesis comes from quantum mechanics. This suggests that nature is not “real”. Particles in a particular state, such as a particular location, do not appear to exist unless actually observed or measured. Instead, they are a mixture of different states at the same time. Similarly, virtual reality needs observers or programmers for things to happen.

Quantum ‘entanglement’ also allows two particles to be eerily connected, so that manipulating one automatically and instantly manipulates the other, no matter how far apart they are. The effect is seemingly faster than the speed of light. Impossible.

However, this can also be explained by the fact that within the virtual reality code, all “places” (points) should be approximately equally distant from the central processor. So you might think that two particles are millions of light years apart, but that’s not the case when they’re created in a simulation.

possible experiments

Assuming the universe is indeed a simulation, what kind of experiments can be deployed from within the simulation to prove this?

It is reasonable to assume that the simulated universe contains many bits of information everywhere around us.These bits of information represent the code itself. Therefore, detecting these information bits proves the simulation hypothesis.recently proposed Mass-energy information (M/E/I) equivalence principle— suggesting that mass can be expressed as energy or information, or vice versa — states that information bits must have small masses. This will give you what you are looking for.

I hypothesized that information is actually the fifth form of matter in the universe.Me too Computed expected information content per elementary particle. In 2022, these studies will Experimental protocol Test these predictions.The experiment erases the information contained inside elementary particles They and their antiparticles (all particles have an “anti” version with the same but opposite charge) are annihilated in a flash of energy, emitting a “photon” or light particle.

Based on informatics physics, we predicted the exact range of expected frequencies of the resulting photons. This experiment is highly achievable with existing tools, Launched a crowdfunding site) to achieve that.

There are other approaches as well.late physicist John Burrow It argues that the simulation accumulates small computational errors that must be corrected by the programmer to continue.he suggested that we might experience such a fix Contradictory experimental results suddenly appear, such as changes in the constants of nature. So monitoring the values ​​of these constants is another option.

The nature of our reality is one of the greatest mysteries out there.the more you ingest simulation The more seriously you take a hypothesis, the more likely you are to prove or disprove it one day.
