How does knowledge circulate in the universe?

Knowledge in the universe is through a continuous cycle of learning and exchange between different civilizations and different countries. An exchange of learning by participating in various cultural events.

I think it's a cycle over time, constantly breaking and creating new, breaking and new, breaking and new, and so on from generation to generation, constantly approaching the truth.

The end is the beginning, in fact, in my opinion, everything in the universe is just a cycle, just like the rebirth of the fire phoenix.

Through education, it is passed down from generation to generation. Knowledge is collated, aggregated, and disseminated among human beings.

Some scientists believe that the universe is a cyclical body. Since the beginning of the universe, the universe has been expanding, expanding to the limit, shrinking back to the singularity, and then happening again**. And so on and so forth. Of course, this is only some people's conjecture.

The universe is time, space, and the matter in space, including planets, stars, and all other forms of matter and energy. According to the theory of large **, it is estimated that space and time appeared 100 million years ago. And since then the universe has been expanding.

We don't know exactly how big the universe is, but we can still measure the size of the observable universe, which is currently estimated to be 93 billion light-years in diameter.

The universe is a mystery, and you can imagine it as long as you make it up.

It's hard to say, the universe is too big and too complicated.

The universe is vast and infinite, boundless, and has no beginning or end. At present, the universe as human cognition is limited to the theory of the formation of the "big universe", the black hole is the center of the big **, and the universe begins to expand around, and after the expansion of the universe ends, the black hole begins to absorb all the stars, matter, including light, in the universe, and finally forms a new universe, and thus loops indefinitely forever.

In order to completely solve the mystery of the universe, the mystery of the black hole will require continuous research and exploration and discovery by human beings in the future.

There is a scientist who says something interesting, he thinks that human beings are a species with a natural tendency to violence, and will create some destructive things, so human beings have been released by the alien ** of civilization. If it is true that human beings are exiled because they are not tolerated by a highly civilized society, then due to their own greedy and destructive nature, the more they explore, the more confusion there becomes, and the nesting of the universe is to lock up human beings.

There is a certain basis for the statement that the universe has been recirculating, following the discovery of black holes, scientists also discovered the Hawking point, which is a basis for the universe to keep circulating, and the Hawking point indicates that the universe will not tear apart, but will continue to circulate.

Yes, like life on Earth, it goes on and on. The universe is a huge system, and the earth is only one member of this system, so it is believed that the universe is always circulating.

Cosmic recycling, to put it simply, can be explained by Newton's law of conservation of matter, in simple terms, it is an object to absorb the ability, and this ability will be eliminated by the transformation and become the energy of other objects, and so on, and the cycle will not be destroyed.

If the changes in the universe are disorderly, then they may be destroyed at any time, but the universe is still continuing well, and it must follow some kind of law, and the cycle is a possibility.

The landlord only saw the current situation of the universe and thought that the universe was a perpetual motion machine. However, the average temperature of the universe, which we call "cosmic background radiation", has been decreasing. From the initial more than 100 billion kWh, it has dropped to the current one.

Even though the energy inside the universe is transferred from one place to another, from one form to another, as you said. But the second law of thermodynamics entropy is forever increasing, the closer the entropy is to infinity, the closer the average temperature of the universe is to absolute zero, and if the universe does not have a big tear, (but on the contrary, I agree that the universe will have a moment of great tearing, because the study of quantum mechanics seems to hide in the quantum information that the universe is tens of billions of years later, and space will appear a hole due to excessive expansion and bring unprecedented disasters to the universe) The last situation of the universe is - heat death, That is, all the particles are far enough away from each other that all the particles do not interact with each other, so how can energy be transferred from one place to another, from one form to another? Also, before the theory of multiple universes, we can think that energy is conserved, and you must know that superstrings and supermembranes believe that gravity can radiate to the shadow film (extra dimension), that is, gravity can carry energy to other cosmic membranes.

Therefore, I believe that if the M theory is successful, the conservation of energy will no longer be applicable to our universe, and as far as I know, the scope of energy conservation will expand to the entire eleventh dimension, and this energy we can call "string energy" or "strings containing energy". This energy is the one that does not disappear or create, it transforms from one form to another; Transition from one geometry to another, giving birth to a new universe.

No problem at all. Energy doesn't disappear, it doesn't come into thin air, it's just circulating all the time.

The definition of a perpetual motion machine should be to convert other energy into kinetic energy only, but this is not the case with the universe, which is the conversion of all energies into each other.

Yes, but don't take it too seriously.

A version of the periodic universe theory believes that our universe is in a cycle of large, expanding, contracting, and again big**, and the cycle of each cycle is 40 billion years, roughly 20 billion years of expansion, 20 billion years of contraction, and our universe is currently in the expansion stage. Some people don't even know how to calculate that our universe is currently in the sixth cycle of the cosmic cycle.

But that's just speculation. Imagine, at the end of the Great Contraction of the universe, all matter will cease to exist, and when the universe is big again, except for the basic cosmological constants (such as the mass-energy ratio, the mass and mass ratio of each elementary particle, the vacuum speed of light, the ratio of gravity and electromagnetic force, etc.), all the celestial bodies and celestial systems that once existed "information" have disappeared, how to determine the cosmic cycle?

We don't even know the shape of the universe or whether it is closed.

It's quite possible that you're saying that because no one knows the answer.
