Human beings live on the earth, and there is water for human drinking, oxygen for human breathing, abundant food resources, and warm and suitable sunlight. The other planets in the solar system are not suitable for human habitation.
A region around the star can be carved out where water can exist in a liquid form, and this area is the habitable zone of the star. The distance from the earth to the sun is appropriate, and the earth is in the habitable zone of the solar system.
From the definition of habitable zone, it can be seen that habitable zone does not mean that life can exist. Like Mars, it is also located in the habitable zone of the solar system, and various human probes on Mars have not yet found signs of life on Mars. The Moon is also in the habitable zone of the solar system, and the environment on the Moon is even harsher than on Mars, and life on the Moon is even less likely.
If we find another planet and put it in orbit on the earth, will there be life on the planet in billions of years? It has a lot to do with the planet.
The surface of the Moon is almost a vacuum, and the atmospheric pressure of Mars is less than 1% of that of the Earth's atmosphere, which is related to the mass of these two stars. If the mass of the planet is small, the escape velocity tends to be smaller, so that gas molecules can easily escape from the planet. Without the protection of the atmosphere, life is easily destroyed by cosmic rays.
It's hard to imagine life in such an environment. In addition, the atmosphere also acts as a heat insulator, so that the temperature does not change too much between day and night. Mars' rotation period is only about 40 minutes longer than that of Earth, but the temperature difference between day and night on Mars can exceed 100 degrees Celsius.
Such a harsh environment is also not conducive to the birth of life.
In fact, the complexity of the birth of life is far beyond the ability of human beings to narrate, and this complexity cannot be described in human language. Humans have been searching for extraterrestrial planets for several years, and thousands of extraterrestrial planets have been discovered, but few of them are relatively close to Earth. The birth of life on the planet is not simply to move the planet to the habitable zone.
-
Moving a planet into the orbit of the earth, although it is very likely to create the same ecological environment as the earth, does not mean that the planet will not necessarily give birth to life, the conditions for the birth of life are extremely harsh, and it is not that the external conditions meet the conditions for the birth of life, and life will definitely be born.
-
In the same orbit as the Earth, then it is very likely that after the previous year, another life will be born, and then another Earth will be formed, and there is still such a possibility.
-
If a planet is moved to the Earth's orbit, then the planet will slowly move over time, and it is likely that life will also be generated, and then a special kind of space will be formed.
-
If a planet is moved to the Earth's orbit, the planet will also have the Earth's ecological conditions, and under such ecological conditions, life is very easy to be born, so I believe that if a planet is moved to the Earth's orbit, life will be born after hundreds of millions of years.
-
There is no life, because life is related to the structure of the earth itself, and such life cannot be replicated.

14 billion years ago, a large ** universe was formed. More precisely, the formation of the Milky Way. 4.6 billion years ago.
Cosmic dust forms our Earth. So, from this point in time, 100 billion years from now, the earth itself. The inside will burn out.
The ground is sunken. A small black hole is formed. If he is formed, small black holes before.
A big star next to Earth. First the inside burns out. Large depressions are formed.
and larger black holes. Then the earth will be sucked in. This cycle should take place in 10 billion years.
If the Earth is sucked in by the black holes of other stars. A new ** will be formed. Spawn new groups of galaxies. and the creation of new groups of galaxies. There is the material of the earth. But there is no more Earth.
The universe is big all the time. Just outside the galaxy. It's happening infinitely.
The universe has no boundaries, and there will be some perseverance at any time. Burned out. That is, the lifespan of this star has reached its limit.
And new small ** points will be formed. And the universe is producing new clusters of information and new stars all the time.
Above this is the Earth. Destiny in 100 billion years and 10 billion years.
So we humans, go to **?
If there are no civil wars and natural disasters, just give to humanity. 3000 years. At the current rate of technological development of mankind.
You can find n in the Milky Way. A planet that resembles the Earth's living environment. Moreover, both light-rich and faster-than-light vehicles can be studied by humans.
Space migration is not a dream.
Humanity at that time. Yes. Survive and live on different planets. Communicate with each other. In this case, even if we encounter a small star impact again, we have a planet to choose from.
This is a question that is analyzed from the point of view of scientific rationality. 100 billion years from now, if human beings still exist, then technology will be against the sky, so it is impossible to describe it now. The return journey is something that we can't imagine now.
Ha! I have heard that there are people who are worried about the country and the people, but I have really not heard of those who are worried about the existence of the earth in hundreds of billions of years?
I'm really lonely and unheard, it turns out that there are still a lot of people in this wolf people's worries! Whether the earth will exist in 100 billion years or not I dare say that the gods don't know, but what I do know is; In a hundred years, you will definitely not be there. [covers face].

But we humans are intelligent species after all, so in the face of this situation, we will not rest on our laurels. We will survive through our own efforts. So will there be humans on Earth in 3 billion years?
Three billion years is a long time for us, and human civilization will change due to various factors, and we can think boldly now. The Earth is in constant danger of natural disasters such as asteroid collisions, supernovae**, solar movements, gamma-ray storms, and geologic activity on Earth.
Not only natural disasters, but also man-made disasters, nuclear wars, and biological warfare can put an end to human civilization ahead of schedule, and the damage to the ecological environment caused by human activities is a problem that cannot be ignored. So the saddest ending is that before 3 billion years old, humans on Earth will become extinct early. The future of humanity will be even better if humanity is fortunate enough to avoid the threat of natural disasters and man-made disasters altogether.
John F. Kennedy, lucky quote) Based on the previous rate of technological development, humanity is expected to soon reach the standard of a first-class civilization.
In 3 billion years, the sun will become more violent, but after such a long period of development, human beings can reach the standard of second-level civilization even if they are not good. In this era, the earth is no longer the only home of human beings, but as the birthplace of human civilization, the earth will be protected like a holy place, where a few humans live. Our Sun is in Jussi City, and the direction of the future is a red giant, and the smaller red dwarf is not a red giant.
Because core helium doesn't build up! However, due to the limitation of the radiation layer between the nucleus and the outer layer, helium cannot communicate with the stars everywhere and accumulates in the inner core, but the yellow dwarf is not tall and cannot burn helium, so it can only wait until the hydrogen is exhausted.
The overall temperature of the sun is on a downward trend, but the sun gets hotter instead of colder. Because the diameter of the sun is larger, the total radiant energy increases. Because the era of helium burning is much more violent than hydrogen, super-coronal activity and an expanding sun could theoretically expand to near Earth's orbit.
-
It's hard to say that in three billion years, the earth's resources will be depleted and there will be no new life.
-
I think there should be, because 3 billion years is too long, and I think humans will live to that point.
-
It is possible, it may not, and whether it will appear in the end is also unknown, and people cannot be accurate **.

In science, human beings do have a lot of doubts about the discovery of aliens, where and when aliens can be discovered, this is what everyone is concerned about at present, what we can do after the discovery of aliens, whether there are more competitive opponents, or will we become friendly space communicators.
In the entire universe, the current exploration is undoubtedly scanning, and there are many planets that have been defined by the scientific community as having life, but it is generally believed that there must be life in our universe, but it may be the earth far away from humans, or the way life exists is different.
Recently, the Australian and British Royal Astronomical Societies have raised some of our doubts about the existence of extraterrestrials, and they believe that our extraterrestrials may exist in parallel universes, and the main point is that even if the universe is destroyed by the ability of darkness, life will still exist without any possibility of extinction.
Scientific simulations have shown that the expansion of energy has no effect on the birth of stars, and even hundreds of energy changes will not cause the death of the universe. The universe is like a living body, with a living body similar to "life". It is expanding and at the same time providing life energy to the universe.
However, for the existence of aliens in the parallel universe, more people believe that there is life on Europa, Jupiter's moon Europa, through the current monitoring, there is a possibility of ocean water on it, so science speculates that there is life, it seems that there are many similar events found in space, and there is a possibility that there is water under the surface of Mars before.
On the whole, this is a speculation on the cosmic planets, all of which say that there is life, the possibility of aliens, and now in addition to the earth, the scientific community has not concluded that any planet with life exists, all of which are further observed and discovered, including the moon and Mars, which have aliens, and Hawking has also said that there are aliens before, so that we are forbidden to approach and explore. Over the years, NASA has also sent probes but still haven't found them, so the project is still a long-term thing, and it's all speculative theories based on phenomenal observations. Many people say that we are looking for aliens now, but in fact, I don't understand what to do.
-
Yes, after all, there are too many unknowns in the vast universe.
-
I think aliens are supposed to exist, but we can't find them yet, or never will.
-
And billions of extragalactic galaxies as huge as our own have been discovered in the universe! Therefore, it is safe to say that there are countless planets in the universe that are suitable for aliens.
-
There are no aliens in humanity yet, but aliens do exist.
-
There are indeed a lot of doubts about the discovery of aliens by humans.
-
There may or may not be, who knows.
-
There will be no aliens among humans.
-
I don't know if the housing prices of aliens are high.
-
We can't find it yet, or we will never find it.

Will there be humans on Earth in 100 billion years? In other words, how many more years will humans exist on Earth?
There are a couple of questions. 1. Nuclear war. In a hundred years, if each country does not make friendship with each other, but fights with each other, the material on the earth and in the ocean will basically be eaten up, leading to the outbreak of nuclear war and the destruction of mankind; 2. Global environmental pollution.
The gradual increase of human beings, the serious polarization between the rich and the poor, and the increasing number of selfish desires have led to the deterioration of the earth's environment step by step, and the toxic substances accumulated in the air, land, and ocean every day and every year have risen and spread in the form of multiplication. 3. It is estimated that in 5,000 years, Mercury will be attracted to the sun, and after deorbiting, it will accelerate towards the sun, resulting in a large nuclear explosion of the sun, resulting in a high temperature of about 400 degrees on the earth, an escape from the atmosphere, boiling seawater, and the seventh mass extinction of mankind.
Although the cutting-edge achievements developed by scientists and technologists today have given mankind a physical instrument that cannot be disbelieved! Our country's eye of heaven is currently the farthest electric glasses that can be found in the universe. The U.S. is now the most advanced country in human beings.
There are products with the primary viable technology that go out of the earth and the solar system. In the future, scientists will develop better new products. With the achievements of these advanced human cutting-edge technologies, those meteors outside the earth that may cause harm to the earth; It won't be like when there were only animals before!
However, mankind's understanding of the earth and the universe so far is still in a superficial stage, and many of the arguments are hypotheses. The survival of human beings on Earth is only a natural phenomenon. As for how long it can survive, it depends on the laws of nature as a whole.
No one can change it, and no one can resist it. What human beings can do at present is to do their best to protect the ecology of the earth, and to ask for as little protection as possible.
The development of science and technology in the past hundred years of mankind has been very important to modern human intelligence; This is just the first result of the rapid development of human intelligence! I believe that human scientists will only make new science and technology benefit the scientific and technological achievements of human safety and happiness on the basis of the existing ones, so that people will be more and more assured, safe and credible! It is believed that when the current and future cutting-edge technology discovers the extinction event that will cause the extinction of dinosaurs on the earth, human science and technology will definitely take measures in advance to protect the roots of human seeds.
Historically, the time that can be suitable for advanced animals is at most more than 200 million years, such as the era of dinosaurs, but because the solar system has passed middle age, the best environmental conditions have passed, human beings have a history of more than one million years, and the history of human civilization is only about 10,000 years, so if human beings are given 100 million years, it is enough to develop into unimaginable civilizations. The reason for the destruction of human beings is that the probability of destroying themselves accounts for more than 99 percent, and the natural destruction of human beings may not exceed 1 in 10,000, so there is no need to be afraid of natural disasters, as long as human disasters are not created, human beings will create cosmic miracles.
If it exists, humans will definitely encroach on the planet. >>>More
