If the universe is expanding, is the space time in which we live changing?

The time and space we live in have not changed much, in short, even if there is change, it is very small and difficult for humans to feel. We all know that the mystery of time is arguably one of the "greatest puzzles" of the universe to date. For hundreds of years, countless scholars and scientists have devoted themselves to the study of time and space.

Albert Einstein, the great physicist of the last century, creatively proposed the "special theory of relativity", which revolutionized the theory of time and turned physics upside down. The special theory of relativity holds that the flow of time depends on changes in speed and gravity;

Moreover, time and space are not opposites, but "complement each other", and under certain conditions, they may even be transformed into each other due to the "Lorentz transformation". Therefore, the expansion of the universe will also have a great impact on our time and space.

So, is the universe expanding? The answer is yes. According to the big ** theory, 13 billion years ago, the Schwarzschild singularity created space-time with the intervention of external forces, and then expanded rapidly; This expansion, judging by the phenomenon of cosmic microwave radiation, has not stopped.

NASA experts finally calculated that the expansion rate was about three times the speed of light. In that case, it does seem to have a very big impact on the plane in which we live: but why can't we feel it in our daily lives?

It starts with another ubiquitous, ubiquitous mysterious force: gravity. Gravitational attraction attracts celestial bodies closer to each other, always canceling out the influence of "dark energy" on the universe and maintaining the stability of space and time.

Therefore, even though the universe is still expanding, the impact on the Earth, the solar system, and the Milky Way is still minimal. The data shows that the Moon is about 0.3 centimeters away from the Earth every year; Whether the time and space have been expanded or narrowed, we cannot feel.

I don't think so, at least the center of the universe should not be affected, and there may be a clear feeling that it is at the edge of the universe, like a balloon inflated, only the edge has changed.

If the universe is expanding, all our space-time is changing, then all space-time will continue to expand, and when it reaches a certain limit, it will **, and the entire universe will be destroyed.

Yes. Because the universe is expanding, it will have a certain impact on space-time, so the space-time in which we are located is also changing.

I don't think it will affect us much in the short term, because the universe is expanding all the time, and we are constantly evolving to adapt to such changes.

In fact, we are just a speck of dust, living in the boundless universe, and the universe is constantly expanding, and the impact on us is very small at the moment.

Because the speed of the expansion of the universe is not static, the universe has experienced a rapid explosion process in the early stage, which indicates that the expansion rate of the universe is generally in a state of gradual slowdown, so it should be more reasonable to describe the expansion rate of the universe as the "Hubble parameter".

I don't think soI think the universe should be expanding faster and faster. Because there are stars in the universe all the time, and the birth and destruction of stars often lead to the expansion of space.

According to human observations, the universe has been expanding, but it is impossible to give a definite answer as to whether the speed of expansion of the universe is increasing or slowing. After all, the level of science and technology of human beings is really limited, and it is impossible to observe the boundaries of the universe at all.

Although science and technology cannot accurately measure velocity, humans have used the distance between planets and the earth to estimate the expansion rate of the universe. Therefore, scientists have been measuring galaxies near the Earth since the last century. After decades of research, it has been proved that the planets around the Earth are moving away from the Earth faster and faster, which also shows that the speed of the universe's expansion has increased compared to the past.

Scientists have proven that the reason why the universe is expanding rapidly is because of a mysterious force pushing it. After this conclusion was put forward, many scientists discussed it, some scientists agreed with it, and some scientists expressed doubts. After all, this conclusion is in theory, not in any practice.

In addition to this, some scientists believe that this mysterious energy should be the newly proposed dark energy. Dark energy is a form of energy with negative pressure that is evenly distributed in space, which is different from the gravitational force we have previously understood. This energy is not an attraction but a repulsion, so it is precisely because of this energy that the universe is gradually expanding.

Personally, I think that whether the universe is expanding rapidly will be studied after the development of science and technology in the future. Nowadays, any doctrine only exists in the concept, and due to the limitations of the level of science and technology, scientists in this era cannot fully verify their claims.

The rate of expansion of the universe is not constant, but faster and faster, which is not a good phenomenon for the Earth and other planets.

The rate of expansion of the universe is not very common, and scientists speculate that the rate of expansion of the universe is slowly increasing.

In its current state, the expansion rate of the universe is also at a certain rate, without any acceleration or acceleration.

When the universe will end, this is still very far away. Because the universe has been in existence for more than 100 years, and then when it really comes to extinction, it will be at least 10 billion years laterIt is still quite distant for humans, because none of the life on Earth is that long. <>

We don't know when the universe will end, but we can figure out when the solar system will disappear and whether the universe will end, which is too far away. Because the universe is so big, so big that we don't know about it at all, the core of the solar system is the sun, we can use the activity of the sun itself to ** the time of the existence of the solar system, according to the inference of scientists, the effective time for the sun to continue to shine and heat will be about 5 billion years,That is to say, the sun will have a big ** in this long time, and then the energy will gradually disappear, and the solar system will disappear. <>

But 5 billion years is still far away for human beings, because the life of our earth is only about 4.6 billion years, and it has not yet exceeded this year. The sun appeared as early as 5 billion years ago, and it is not a problem to continue to exist for another 5 billion years according to the current luminous intensity of the sun, and the time when human beings appeared from the earth is 5 million to 7 million years, from the beginning of human ancestors, we have only lived on the earth for so long. In another 50 million years, the question of whether human beings will exist is a question, and the chances of another 500 million years are already very small, let alone another 5 billion years.

If human beings still existed at that time, then it is believed that the technological level of human beings themselves has developed to the extent that they are completely capable of crossing the solar system to reach other emotions, and even to cross the Milky Way galaxy to reach other large planets. Because the development of modern science and technology of mankind has only been a few hundred years, it has already had the ability to go to heaven and earth, so after tens of millions of years of development, I believe that mankind will definitely have this breakthrough.

According to the research of relevant scientists, the universe will not completely disappear until at least tens of billions of years later; Under normal circumstances, it will not continue to expand.

It is not known when the universe will die, but judging from the current research, it will continue to expand.

According to relevant reports, the universe will probably die out in 10 billion years; Generally speaking, it will not continue to swell.

Summary. Kiss Hello Glad to answer for you Space-time and the universe are inseparable concepts, and they are intertwined with each other. The universe refers to the existence of all matter, energy, space, and time, and space-time is the structure that describes space and time in the universe.

In other words, the universe is made up of space-time. Therefore, we cannot say how the world overshadows the universe, because the world is a part of the universe. We can understand the world as the reality we live in, including everything we know, see, and perceive.

The world is the appearance of the universe, and all existence and events take place within the framework of the universe. When we talk about the world, we are mostly referring to the sphere of human concern, such as life, material, society, and culture on Earth. The universe, on the other hand, is a macroscopic perspective, including countless galaxies, planets, stars, and other cosmic matter.

In short, the world cannot overshadow the universe because the world is a part of the universe, and they are an indivisible whole. <>
