Look at it
This is a map of the universe drawn by astronomers, and this is a map of the distribution of neurons in the human brain in brain science, and when you compare the two maps, you will see that the shape of the universe and the brain are very similar.
Therefore, some scientists believe that the universe may be a brain with the ability to think, and we may live in its dreams, because from a principle point of view, the tens of billions of neurons that make up the brain and the hundreds of billions of galaxies that make up the universe all follow the same rules, and if consciousness is really the inevitable result of the accumulation of a large number of inorganic matter, the universe itself should also have the ability to think.
In terms of proportion, 77% of the human brain is water, 70% of the universe is dark energy, the bioelectric speed inside the human brain is more than ten meters per second, and the speed of light in the universe is 300,000 kilometers per second, which may cause the thinking speed of the cosmic brain to be very slow, and it will take hundreds of billions of years to go through a complete thinking process.
At this time, you will find that what we are discussing is not whether the universe has consciousness, but what is the reason for the emergence of consciousness, neuroscientist Toruni believes that consciousness and intelligence are two different things, for example, the intelligence of the computer is very powerful, it can beat humans in chess and Go, but it has no consciousness, that is to say, it cannot control itself and cannot affect the objective world, it is only more effective than the human brain in some fields.
This inability to react to the outside world distinguishes between inorganic matter and organic matter on the earth, such as stones and trees, the former can only be passive, but the latter can undergo some changes according to the sun's illumination and growth process, from this point of view, we can say that trees are more conscious than stones, that is, the strength of consciousness is directly proportional to the complexity of the object, the more complex or organic things, the higher the probability of consciousness.
So the cosmic web of trillions of galaxies is theoretically more conscious than the human brain, but the speed of light in a vacuum is too slow for the universe to complete a lot of thinking in an instant.
Some brain-opening ideas believe that supermassive black holes in the core regions of various galaxies can actually connect all parts of the universe, they are responsible for the thinking of the cosmic brain, and the real quantum entanglement, which can theoretically transmit more than the speed of light, may also be the operating mechanism behind the cosmic brain.
From the current observations, galaxies will form a network structure on the scale of 10 billion light-years, and be divided by cosmic holes flooded with dark energy, and the Laniakea Supercluster, which serves as a node between the Great Wall of the Universe, is difficult to imagine any information flowing quickly in a system that can easily reach tens of billions of light-years.
In fact, under the confinement of the speed of light, scientists believe that we will never be able to see the whole picture of the universe, the observable universe with a diameter of 93 billion light years is only a small part of the real universe, we see that the galaxies are what they were millions of years ago, what the current state of the universe is, and we will not know until the light that carries information flies to the earth.
