Does the soul really exist? Scientists propose the "Boltzmann brain", and many people have come into contact with it

The concept of "soul" makes people curious and afraid. It refers to whether humans will survive in another form after they die. In mythology, humans are composed of body and soul. When they die, their souls will leave their bodies and enter heaven or purgatory.

However, with the continuous development of science, humans have gradually realized that the so-called "soul" is actually a product of spiritual or brain activity. After a person dies, spiritual thinking no longer exists.

Current theories hold that human consciousness is generated by brain activity. After the brain dies, brain cells and neurons stop functioning, and the brain's memory, consciousness, as well as human limb movements and senses will cease, meaning the end of life. Even if the soul really exists, it will disappear with the death of the body.

But scientific theories are always on the road, constantly developing and moving forward. Some theories are only correct at the moment or under certain conditions, and will change in a different environment or time. To give a simple example: deep in the "black hole" of the universe, at the singularity, human physical laws will become invalid. In this case, the original theories will become waste.

So, if one day in the future, scientists really prove that the "soul" can be "immortal", what impact will it have on our lives?

The birth of any new thing will not change people's original life at first, but it must change people's cognition and views. If scientists prove that souls can be immortal in the future, it means that they can exist forever. Now cutting-edge technology has realized this, and scientists are working hard to achieve the preservation and transfer of consciousness.

Scientists believe that the self-consciousness in the universe is in a "low entropy" state (the higher the "entropy", the more chaotic it is, and the lower the "entropy", the more orderly it is), and human self-consciousness also belongs to this state. From what humans know so far, the "entropy" in the universe is very low, and all the major galaxies and celestial bodies are running in a regular manner, and stars are also outputting light and heat steadily.

This means that the "entropy" of the universe was lower in ancient times, although we cannot be sure that the universe is a closed loop. However, overall, the "entropy" in the universe will become higher and higher with the transfer of energy. In this increasing process, there is a probability that a large number of low-entropy self-consciousness will appear. These self-consciousnesses can exist alone without the help of the body, just like a brain without attachment. Such consciousness is called a "Boltzmann brain."

Why do scientists believe that "Boltzmann brains" exist? This is because, in terms of probability, the probability of the emergence of "Boltzmann brains" is greater than the probability of the emergence of self-consciousness similar to humans that can reproduce itself. Scientists believe that since humans can appear in the universe, "Boltzmann brains" are also likely to appear, but many of them disappear in an instant in the form of "flash in the pan". Some studies have shown that the occasional "flash of inspiration" in the human brain may be related to the "Boltzmann brain".

The "Boltzmann brain" re-recognizes human self-awareness from a data perspective. Although each of us has consciousness, it is still difficult to find such self-awareness in other places in the universe except the earth. In addition to the "Boltzmann brain", scientists also proposed the concepts of "dark matter" and "dark energy". They are different from ordinary things and do not have the ability to radiate and absorb light, so humans cannot see them.

Based on these principles, some of the world's biggest and richest people, including Silicon Valley scientist Elon Musk, are looking forward to and trying to enable humans to be free from their bodies in the future and continue to live in the form of "digital consciousness." To this end, Musk's Neuralink company is working in this direction and has completed experiments on live pigs and monkeys.

Not long ago, a brain-computer interface company called Synchron helped a high-level paraplegic and mute ALS patient to send a tweet by controlling the computer through consciousness. Although the tweet consisted of only a few short words, "Hello world", it demonstrated that consciousness can really be uploaded and change the world.

Consciousness is really amazing. It cannot be seen or touched, but it can be understood and expressed in words. This is a bit like dark matter and dark energy. Although they cannot be seen, they silently affect the universe. Studies have shown that in the vast universe, dark matter plays the role of "glue", sticking everything in the universe together and maintaining the stability of the universe's galaxies. If there is no dark matter in the universe, most of the stars in the Milky Way will be out of orbit and disappear.

Dark energy accounts for 69% of the total mass-energy of the universe and is the main component of the universe. It is dominating and accelerating the expansion of the universe. Although scientists still have many doubts about dark matter and dark energy, it is now certain that they are everywhere and dominate our world. So is consciousness the same? Although it is invisible, it dominates the fate of mankind?

Some people believe that the soul may still exist after human death, and its form may be somewhat similar to dark matter and dark energy. However, there is no scientific evidence for this hypothesis.

If it is really discovered in the future that the soul can exist without the body, will it affect human life? I think it probably won't, because the universe itself is full of dark matter and dark energy, and we can't perceive it in daily life. Just like Newton discovered gravity, and Einstein proposed the theory of relativity on this basis, it just makes us understand the earth and the universe better and improve our lives, which will only get better and better.
