The world is virtual?

Our human perception of the outside world is the result of our brain's processing of various bio-electric signals generated, for example, our visual system will convert the external light into bio-electric signals, and then these signals will be transmitted to the brain, after the brain's processing, we "see" the outside world, the same, our Hearing, touch, smell, the taste is also produced in this way.

If the bio-electric signals coming into our brain are simulated by a computer and not from our real sensory system, can we notice the difference? As long as the computer is powerful enough, and its simulated bio-electric signals are real enough, then our brain can not distinguish, in this case, we can also produce the "real" perception.

Further, it is theoretically possible that the functions of the brain could be replaced by sufficiently complex programs, which means that the brain could be just a program and not an entity.

So reasonable speculation is that if there is a super system connected to all human brains, and even these brains may only be programs, then if the system can perfectly provide a variety of real-time signals to each brain, all humans will think they live in a real world, but the actual situation is that the world is just a virtual system.

So the question arises, the world we live in is virtual? Many people believe that the world may be virtual, and researchers point out that there are six suspicious signs that the world we live in may be virtual, and we may want to understand.

One, for a computer, no matter how powerful it is, its performance is ultimately limited. Interestingly, our world does have various limits, for example, the speed of light is the limit of speed, and various Planck constants are the limit of precision, once beyond these limits, the laws of physics as we know them will lose their meaning.

Second, from the perspective of the microscopic world, the world we live in is composed of a large number of microscopic particles, and in the absence of observation, the state of these microscopic particles will always be in a vague "superposition state", only after being observed, their state can be determined.

The researchers believe that in our game programs, to effectively save system resources, the programs usually display only the details of the player's region and blur the other regions, which is similar to the behavior of microscopic particles.

Third, quantum entanglement has been described by Einstein as a "ghostly over-distance action", but from the program's point of view, this may be the result of the program referencing two pointers to the same object.

Fourth, the puzzling "double-slit interference test" and its subsequent "delayed quantum erasure test" suggest that microscopic particles seem to be able to give specific results according to the behavior of the observer, and may even violate the law of causality explained by the program. This may be the result of the simple use of conditional statements by the program.

V. Jim Gates, a theoretical physicist at the University of Maryland. Jim Gates, a theoretical physicist at the University of Maryland, in the course of his research on super-symmetry in string theory, discovered that some of the equations describing the fundamental properties of the matter of the universe appear to have embedded computer codes, which he described as having only "1" and "0" forms. According to his description, these codes only have two forms, "1" and "0", and the way they appear is very much like the "error correction code" in our common web browser.

Six, extraterrestrial civilizations have always been a topic of interest to us humans, after all, the universe is so big and has existed for so long, the universe of planets is too many to count, from the point of view of probability, there should be a large number of extraterrestrial civilizations in the universe, but the actual situation is that we have never found any definite alien civilizations.

Researchers believe that if the world we live in is virtual, then such suspicious signs can be reasonably explained, namely: the computer running this virtual world has limited arithmetic power to support only one intelligent civilization, and as for the universe to look so vast, it is only an illusion created by the system for humans, who are unable to detect it because of the extremely limited range of human activities in the universe.

Epilogue

The "virtual world theory" is shared by some famous people, such as the famous physicist Stephen Hawking, Microsoft founder Bill Gates, and and Space founder Elton Musk, it is worth mentioning that Musk even claimed that. "The probability of humans living in the real world is probably less than one in a billion."

Of course, the "virtual world theory" is only an unproven point of view, is a hypothesis for people to explore the nature of the world, although this hypothesis is logically sound, the hypothesis is after all hypothesis, so we look at it, do not have to take it seriously.
