About the universe and space time and man, the relationship between man and the universe

In fact, the universe is just the definition of human beings.

There is nothing outside the universe.

But in fact, the universe is defined by space.

The universe is just an infinite stretch of space.

But it's not really a space either.

But does it exist only in the universe?

Not for space.

There is more than one.

Some ** have written on Subspace.

Actually, it makes sense.

But it's not just that.

The universe we live in can also be called subspace for other spaces, but the world is composed of countless subspaces.

Can black holes actually destroy objects?

It's not, it's just a forced intake of individual spaces.

And the destruction of a large planet can "blow up" this mouth.

So the universe as defined by humans is just one of the spaces.

Seriously fight and despise copying.

Scientists have conjectured and have already successfully experimented with the existence of antimatter.

In other words, if there is positive matter on one side of the universe, then the same antimatter must be produced on the other side.

When a person dies, it will be decomposed into molecules, and in 15 billion years the sun will be extinct, it will expand, and finally, it will be a white dwarf, and finally it will disappear again At that time, the solar system will no longer exist, and you will not feel it when you die!

Relativistic explanation: The universe began 15 billion years ago, and as the matter in the universe increases, the expansion will stop, and later, it will contract, and then the universe will disappear!

We'll never know what happens in the future!

The most relaxing day is always yesterday. Be happy!!

Actually, I've often thought about some of the same questions as you: protons and neutrons make up atoms, and atoms make up molecules, ......Until the world that makes up our world, the current human science and technology is not enough to observe the smallest matter, no one dares to say that quarks are the smallest, and no one dares to say that the universe is the largest, and the vast universe has thousands of weather, but it can't escape the word "cycle". So I think that the people who have invented a fast enough flying machine may not be able to find the end of the universe, and the so-called immortals may be aliens, of course, these are my guesses, no comment. Occupy.

According to reports, there are 200 billion "brothers and sisters" of the sun in the Milky Way, and scientists have found 150 stars with planets orbiting, which are distant relatives of the earth. Researcher Wang Sichao made a speculation that even if one of the 10 stars has a planet orbiting, then the earth should have 20 billion brothers and sisters in the galaxy, just like only the earth has advanced intelligent life among the nine planets of the sun, then there should be 100,000-150,000 planets suitable for the development of life, and then produce intelligent life to form a technological civilization, and they should have a civilization similar to or more advanced than the earth.

Here's a personal opinion: UFOs don't have to be alien vehicles; Aliens have not necessarily been to Earth; In a short period of time, humans could not find a clear clue about aliens.

Resources.

To the universe, man is a fart.

Regardless of the birth of man or not, the universe will continue to evolve according to the laws of physics.

This is the insignificance of man.

For the universe, man is a product of evolution and a part of the universe. The universe is able to perceive itself through human beings.

This is the greatness of man.

The above is just a very subjective impression of me as an individual who is part of the universe. But I can use words and words to record this feeling with my mobile phone.

In the end, the universe is meaningful with human perception, or is it meaningful without human beings? I think this question is very easy for me as a materialist.

The way the universe is is not at all subject to human will. To the individual, your happiness, pain, and happiness are the whole world. However, human perception, whether happy, painful, or happy, is a reflection of the objective world in one's own heart, and has nothing to do with the universe.

The universe does not seek meaning. Meaning is given by humans. Human beings need meaning to live, so meaning is created.

We can summarize some laws from our long-term observation of the universe, but these laws are only judgments made by human beings from their own perspectives. The universe itself does not know that there are Newton's three laws, nor does it know that there is relativistic quantum mechanics. But the wonderful thing is that these laws can be used for some things.

So these laws are good laws. If you can't, it's.

Being able to perceive the universe, being able to perceive oneself, creates a sense of loneliness.

Because of this awareness, loneliness is precious.

Enjoy the precious feeling of solitude.

Space and the universe, the universe is a little bigger.

Space refers to the cosmic space outside the Earth's atmosphere that hits hail, and the entire space outside the atmospheric space. The universe is a hierarchical, expansive, diverse system of celestial bodies that is constantly moving and developing.

The universe has a hierarchical structure, for example, planets, asteroids, comets, and meteoroids all orbit around the central celestial body, the Sun, making up the solar system. Space does not use the term hierarchy.

Related information: The universe is an expanding system of celestial bodies, and the universe evolved from an extremely dense and extremely hot primordial state before a finite time in the past, and has been expanding to reach its present state.

Some studies have argued that the diameter of the universe could reach 92 billion light-years, or even larger. Space only changes with the expansion of the universe, for example, the temperature is constantly decreasing, and space has become a cold environment, with an average temperature of sub-zero.

The concept of the universe, infinitely long time and infinite space, was mentioned earlier, and it was said that they were like a plane Cartesian coordinate system. It is not a planar Cartesian coordinate system, and there is no horizontal and vertical correspondence. It is also not material, but the way in which human cognition is generated.

It is energy that makes up the material world, and if it is energy, it will inevitably be lost, and energy does not seem to be able to be kept constantly. If you think about it, you can also know that all the material existence in the universe needs energy to maintain, and it must absorb enough energy to maintain the immediate state of matter. Isn't that energy always in a state of consumption?

However, secondary school physics tells us that energy is constant, it does not become more or less, it only changes from one form to another. In fact, this is not contradictory to the continuous consumption of energy, the total energy in the universe is still unchanged, and it only changes from one energy to another. Just as electrical energy becomes light energy, in the process electrical energy is consumed, but light energy is produced.

At the same time, light energy becomes other energy. For example, photosynthesis becomes energy that promotes plant growth. Because energy cannot be stored constantly, it is always in the process of transformation, so there will be no constant existence of matter in the universe.

When the energy of any state is exhausted, when the energy that depends on the substance to survive is exhausted, then the substance will lose the basis of its existence, and can only become other matter by absorbing other energy. It's a lot like viruses that mutate, and could viruses be the energy that sustains life?

The constant transformation of the energy that maintains the existence of matter in time and space, constantly changing from one state to another, also causes constant changes in the state of matter. Do you guess that energy is different from long and short like light waves? Like particles, there are big and small?

Modern physics tells us that light has wave-particle duality. It has both the nature of a wave and the nature of a particle.

We can all figure out that there should be no smallest particles in the physical world. Some are only the smallest particles that can be found so far, and as technology continues to advance, smaller particles should be discovered. The phenomenon of light waves lets us know that there are infrared rays and ultraviolet rays, infrared rays are too long for us to see with the naked eye, and ultraviolet rays are too short for us to see, and only a small part of the length of light waves that can be seen by the naked eye is suitable for discovery.

It is not difficult to understand that less than five percent of the matter in this universe can be discovered by us.
