Portsmouth, UK, Nov. 22 (Interview) Physicists have long struggled to explain why the universe began in conditions suitable for the evolution of life.
Why do the laws and constants of physics take on the very specific values that allow the development of stars, planets, and ultimately life?
For example, the expansion force of the universe, dark energy, is much weaker than theory suggests, allowing matter to clump together rather than tear apart.
The common answer is that we live in an infinite multiverse of universes. Therefore, it should not be surprising that at least one 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 branch of science called informatics, 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 “generates” 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.
In 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 adage “it from bit”.
In 2003, British philosopher Nick Bostrom of the University of Oxford formulated the simulation hypothesis. This shows that it is actually very likely that we are 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. .
Massachusetts Institute of Technology physicist Seth Lloyd has taken the simulation hypothesis to the next level by suggesting that the entire universe could become a giant quantum computer.
And in 2016, business mogul Elon Musk concluded, “We are most likely in a simulation” (see video above).
There is some evidence to suggest that our physical reality may be a simulated virtual reality rather than an objective world that exists independently of the observer.
Virtual reality worlds are all based on information processing. This 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 states that there are smallest discrete units of 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.
In addition, math equations, numbers and geometric patterns are ubiquitous, making the world look completely mathematical.
Another curiosity in physics that supports the simulation hypothesis is the maximum velocity limit in the universe, which is 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.
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. The recently proposed mass-energy-information (M/E/I) equivalence principle (which suggests that mass can be expressed as energy or information, or vice versa) states that information bits must have small masses. increase. This will give you what you are looking for.
I hypothesized that information is actually the fifth form of matter in the universe. We also calculated the expected amount of information for each elementary particle. These studies led to the publication in 2022 of an experimental protocol to test these predictions.
In this experiment, an elementary particle and its antiparticle (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. The information contained in the elementary particles is erased by letting
Based on informatics physics, we predicted the exact range of expected frequencies of the resulting photons. This experiment is highly feasible with existing tools, so we launched a crowdfunding site to make it happen).
There are other approaches as well. The late physicist John Burrow argued that simulations accumulate minor computational errors that must be corrected by programmers in order to continue.
He suggested that we might experience fixations such as the sudden appearance of conflicting experimental results, such as the constants of nature changing. 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 seriously we take a simulation hypothesis, the more likely we are to prove or disprove it one day. (conversation)
