What does it seem to you that exists outside the universe?

In fact, think bigger, broaden your horizons, and think about it. The universe seems vast to us, but to the eyes of ants, we humans are also vast. Maybe there is a creature outside the universe, they look at us like we look at ants, you don't have any means to deny their existence, and the terrible thing does exist.

Outside the universe is actually oneself, oneself is the universe, oneself is not the body but the mind, to put it another way, the universe is the mind, the mind is tangible, the thought has no edge, the universe has no edge, if you have to define the universe outside the mind, self. Without thought, there would be no universe, and it would be published from the edge of the universe.

Scientists have inferred that there are countless parallel universes, how can we assume that there is a giant river, and there are countless cosmic bubbles in this river, and many bubbles are constantly blown up and expanded. Of course, there are bubbles that shrink and burst. And our universe is one of these cosmic bubbles.

It's an interesting conjecture. Just as we look at the changes in the small microcosm, are there also huge giant creatures watching the growth and destruction of countless universes in the river? Some scientists also wonder whether the wormhole proposed by Albert Einstein is a channel connecting many universes.

I think there is no universe at all, and the reason why we can't find the boundary of the universe is because the universe itself is a spherical surface, and there is no end to it, just like the earth back then, people think that the world is boundless and big, and as a result, the earth is a sphere for a long time.

People will always know what is outside the universe, human beings are evolving little by little, the universe is also changing, maybe the universe in our eyes is like a planet in the eyes of others, maybe there is a big universe in the universe, maybe we are just a puppet, maybe the universe is like a glass ball, we are just a small particle of dust, I personally think that the universe has a boundary, there may be another universe outside, or it may be a mess, it has not yet evolved, this is just my personal opinion.

If there is an "outside", is it still called the universe? The current cosmology is so varied that it is simply a pot of porridge. The original meaning of the universe is the sum total of all forms of physical existence.

What size universe and multiverse, all of them have changed their concepts and blatantly violated the "law of sameness", which is "scientific superstition"!! Although the spatial structure and movement patterns of the universe are extremely mysterious, there is no doubt about its uniqueness and variability. If the universe is so easy to know, then the process of human cognition will be terminated.

So far, scientists do not have a definite answer to these questions, some scientists believe that what happens in space outside the universe should also belong to a part of the universe, obviously this problem is not explained by the previous four-dimensional space-time, this is because, under the framework of high-dimensional space-time, the universe does not have any edges, which does not exist the so-called space outside the universe.

There is no space outside the universe, nothing. It can be understood that there is only this universe, and this universe is "infinite", and there is no other universe.

Let me just say that there is no answer to the question of interpreting the universe from the perspective of human beings in three dimensions. For example, if you walk on the surface of the earth and never get to the edge, the answer is that the earth is infinite. But we now know that the Earth is not infinite, because you can actually leave the Earth with a light jump, which is from 2D to 3D.

The three-dimensional view proves that the earth is finite. If you want to interpret the universe, I'm afraid you have to use other dimensions, but what dimension should you use? Perhaps this is far beyond the scope of human cognition.

If there are multiple universes, there are other universes outside of our universe, but the theory of many universes is still just an unestablished theory.

The universe is collectively called space.

The big ** model believes that the original universe was an ultra-high-temperature, high-density "point". About 18 billion years ago, this "point" suddenly **, only 10-36 seconds, accompanied by the supercooling phenomenon of vacuum phase transfer, this "point" expanded by dozens of orders of magnitude in an instant, becoming a one-centimeter-scale universe.

After that, the universe continued to expand, and the temperature began to drop from billions of degrees Celsius, and at about 55 million degrees Celsius, neutrons and protons were generated from the energy of the cooling process, which in turn merged into atomic nuclei, and these processes took only 3 minutes. About 300,000 years later, when the temperature of the universe drops to 3,000 degrees Celsius, free electrons are captured by the nucleus to form atoms. For about 30 million years that followed, those atoms continued to expand outward.

The universe also continued to cool, and by the time the cosmic temperature dropped to 167 degrees above absolute zero, atoms began to coalesce to form thin gases. Since then, it has evolved into new celestial bodies due to density fluctuations and gravitational effects. After more than 10 billion years, it has shown a variety of material forms, and has become the universe today.

Since the cosmic grand 15 billion years ago, stars and galaxies have been scattering outward. In fact, the expansion is accelerating. Steinhardt of Princeton University in the United States said that the universe has no beginning and no end, and the universe will never stop and happen again and again.

This is the universe.

The universe is infinitely large, with no borders, and therefore no inside or outside.

In fact, there is no answer to this, the big ** can't be fully explained, the big ** itself also has doubts, scientists also think that the universe is edged, and it is constantly expanding, and it is a parallel universe opposite to us outside the universe, but I personally think these views are a bit far-fetched.

For the question itself, it is recommended to read three books by Stephen Hawking, but still no concrete answer will be found.

The question goes far beyond astronomy and astrophysics, and may remain a mystery thousands of years from now. This question has risen to the level of philosophy, and materialist atheists cannot answer it.

This is an unsolvable question, and "A Brief History of Time" is recommended

Hehe, any question, a thing to break the casserole to ask the end is unsolvable, whether you ask about the tangible existence or the intangible existence "such as the invisible real existence, heart, honor, fear, beauty, love, affection, etc.", such a question will make life feel extremely frightened and afraid, and even collapse, but when life is true, good, and beautiful, that feeling is enough to eliminate the question you asked, and you will nod deep in your heart The meaning and value of existence. Perhaps few people in the world can experience the feeling of extreme peace and happiness in the soul when there is a kind of light when death, and the feeling that gives you the most beautiful moment of love is the same as the feeling I described, it is a feeling of eternal life, and all troubles, fears, and doubts can give you an answer without words.

I hope it can help you a little, I know the pain of life in the pursuit of these questions, but the pain is also good, at least you are pursuing the truth, but this path is extremely dangerous.
