From the day human beings were born, they began to look up at the starry sky above their heads. The ancients didn’t know much about the mysterious starry sky, and many of them were even mythical. The ancients did not have scientific guidance, and the mysteries of the universe could only be pushed to the gods, so many myths and legends appeared.
With the continuous progress of human civilization, we embarked on the path of scientific and technological development hundreds of years ago. With the guidance of scientific knowledge, we have a new understanding of the world, and we have also stepped out of the earth to see a vast Cosmic space. So must the universe in our knowledge be the real universe?
Perhaps many people believe that seeing is believing, that what we see is real, everything we see in the world, everything in the universe is real. However, with the rapid development of human science and technology, especially the continuous advancement of virtual reality technology, some scientists have questioned the authenticity of the universe in which we live, and some scientists speculate: Our universe may not be real, but a creation. Virtual universe.
Many people may not agree with this conjecture, thinking that scientists are completely nonsense. How can the universe we see is fake? In fact, as long as we analyze it carefully, you will also have doubts about the authenticity of this world.
I believe many friends know that our cognition of things actually comes from the human brain. The brain is an extremely complex and mysterious structure. Until now, scientists’ understanding of the human brain is just a little bit of fur. We usually understand the world. We first transmit what we see to the brain’s visual system through our eyes, and then through complex processing, feed back to the brain.
The brain allows us to understand what kind of information, we can only passively admit it, the brain tells us that the thing in front of us is a stone, then we know that it is a stone. But if the brain is deliberately or there is a BUG, then it will move wrongly or even stop moving. At this time, we can’t see or feel anything.
Through this understanding, we understand that all human perception and cognition of the outside world are controlled by the brain. If the cognition of the brain itself is wrong, then the information sent to us is wrong. Seeing this reminds me of the famous “brain in a tank” concept.
The “brain in a tank” is a conjecture put forward by scientists. If a person’s brain is removed from the body through an operation, it is placed in a tank containing a nutrient solution to maintain brain survival. Then connect the nerve endings of the brain to the computer, then this computer will send information to the brain according to the program, so that he can maintain the illusion of everything being completely normal.
All the information of the brain in the tank is transmitted by the supercomputer. At this time, the brain does not think that it is in a tank, nor does it think that the information in the brain is virtual. It will only continue to recognize all of this. It is true. In fact, this is a kind of virtual reality created by computers, which perfectly fools the brain.
The conjecture of “brain in a tank” easily reminds us of the universe in which humans live. Will it also be a virtual reality universe created by supercomputers? Supercomputers transmit all information to the human brain, making us mistakenly think that this is a real world, but in fact, everything we see, including ourselves, is just a computer program.
Some 3D games that we like to play are equivalent to a virtual world, created by humans. Only because these games are only 3D technology, we can naturally easily know that this is a virtual world. But if in the future, with the continuous advancement of human technology, after we have mastered mature virtual reality technology, we can create a virtual world that is infinitely close to reality.
At that time, human consciousness can enter this virtual world through some equipment, and you will see a virtual world that is completely indistinguishable from true and false. Since we enter the virtual world through equipment, even though it is extremely real, we know that this is a virtual world created by humans.
But for those virtual humans in the virtual world, they will not recognize that the world they live in is fake, because what they see, touch, and feel is so real, how could it be a fake world? ? But the fake is fake, and no matter how true it is, there will always be some loopholes. This is like a computer program. There is no perfect program, more or less loopholes will exist.
Perhaps some scientists in the virtual world, through some clues, will also guess: Will this be a created virtual universe? By the same token, if the universe in which we live is virtual, there will inevitably be some loopholes. Only by finding these loopholes, we may be able to prove the truth of this world.
At present, scientists are mainly working on quantum mechanics to find these loopholes. We must know that from a macro level, it is difficult for us to understand the nature of this world. To understand the deeper mysteries behind the macro, we need to walk into the micro world, which is equivalent to walking into the computer program.
There are some phenomena in quantum mechanics that completely subvert the cognition of scientists. They violate the scientific laws of the macroscopic world, such as quantum superposition, which is completely impossible in the macroscopic world, but actually exists in quantum mechanics.
Another example is the mysterious phenomenon of quantum entanglement, which makes scientists feel incredible. In the macroscopic world, speed has a limit, that is, the speed of light. Therefore, as the distance increases, it will take more and more time to transmit signals in the universe. But in the quantum world, the existence of quantum entanglement makes the distance zero.
No matter how far the distance between the two particles is, as long as the entanglement occurs, the induction can be instantaneous. This transmission efficiency can no longer be explained by speed, which completely subverts our cognition. And it is these incredible phenomena of quantum mechanics that have led some scientists to speculate: Our universe may be virtual.
If humans create a virtual universe, no matter how big the virtual universe is, there is no concept of distance in human computer programs. Every signal sent by humans can be instantly transmitted to all corners of the virtual universe. Some people think that this kind of instantaneous transmission regardless of distance may only be possible in the virtual world.
Of course, all of the above are still people’s guesses. Whether the universe we live in is real or virtual, it needs more research and exploration by scientists. Of course, in the future, if scientists prove that the universe is virtual, it will undoubtedly be a major blow to mankind. At that time, how will you face the world and everything around you?
