None of these 50 years will be possible.
First of all, the entire solar system is the only Earth that has a suitable environment for human habitation, and other planets (such as Mars and Titan) must be modified to barely allow humans to live. But the Planet Transformation plan is still theoretical, and even if it is implemented immediately, it will not be possible to build an entire ecosystem in more than 100 years.
If you want to enter the extraterrestrial world in the short term, you can only seek to go outside the solar system, but you need to overcome the problem of distance. It would take decades for today's spacecraft to fly out of the solar system at the earliest, and human beings have a limited lifespan after all, and they can't reach other galaxies hundreds of light-years away to find settlements in their lifetimes.
Some people will say that refrigeration technology can be used to stop people's metabolism and thaw after reaching the destination, which is a very beautiful theory, but now technology can only cryoppreserve corpses, and living organisms cannot survive normally after refrigeration and thawing.
In addition to the longevity issue, there is also the issue of fuel**. The spaceship can't take off with too much fuel, otherwise it won't be able to fly. Before it flew out of the solar system, the fuel on the ship had been exhausted, and the future speed could only be accelerated and replenished by the force of passing stars.
After leaving the solar system, there are no stars that can provide power to other galaxies, and even with the solar sail in the experiment, it is too far away from the energy source to be able to reach the whip.
There is also a hellish belt of rubble around the solar system, and it is very questionable whether the ship's hull will be able to move through this space unharmed.
There are also opinions that the use of black holes in time and space folding to make spacecraft make space jumps to quickly reach other galaxies, however, what a black hole is so far we are limited to theoretical debate, and even some astronomers deny the existence of black holes at all. If black holes do exist, the existing laws of physics are invalid for it, and it will take a lot of time to understand and explore.
So far, our dream of stepping into the stars is only a dream, and even this generation may not be able to achieve it in their lifetime.

We can't see it anyway, most likely Mars!

No. It is difficult for mankind to destroy the earth with the current stockpile of nuclear bombs. Generally speaking, nuclear warfare and warfare will destroy the world, referring to the fact that nuclear bombs will destroy us as human beings. But if human civilization is gone, it will be gone, and the earth will still be that earth.
The power of the nuclear bomb is very great, and he is the one that human beings currently have mastered, and he releases the most energy at one time. Most of the world's nuclear power is about 1 million TNT. However, it is also very small compared to the earth itself.
At present, mankind has tried to explode more than 2,000 nuclear bombs, which is not painful for the earth.
After the occurrence of nuclear **It produces glowing fireballs, followed by mushroom-shaped clouds of smoke. This is a typical sign of nuclear **. When the nucleus is in the air at a certain altitude above the ground, the high-temperature and high-pressure projectile rapidly expands in all directions and heats the surrounding cold air with X-ray radiation.
The characteristics of hot air absorption of high-temperature radiation make the heated and pressurized hot air mass a sphere with a roughly uniform temperature, and the temperature and pressure have a sudden front, and this hot air mass is called an isothermal fireball.

What is the definition of the end of the earth? Is the earth **? Or is it compressed? What kind of destruction is it?
First of all, what is the demise of the ball?
Humans are living beings on Earth. This organism is material, made up of all kinds of matter on earth. It has evolved over a long period of time to the product of today.
Matter is indestructible. The material that makes up the earth is also imperishable. However, it can be transformed into another form.
When there were no humans, the earth already existed.
When there were humans. The earth is known to man.
After the extinction of human beings, the earth will return to those material bodies, and human beings cannot occupy the highest level of life on the earth forever.
Because in ancient times, the creatures on the earth were not ruled by humans, but by other animals. Based on this, it can be realized that after the death of human beings, it will be a superior creature that will rule the earth.
Now let's talk about time, the earth has existed for about 5 billion years, and there will be 5 billion years to live. Because in about 5 billion years, the sun will burn out. The Sun will turn into a red giant.
When the Earth's orbit enters the interior of the Sun, the matter on Earth transforms into another form. A gaseous nebula. These nebulae then wander around the universe, cool, and then regroup into new spheres.
A new world has been created, and under the right conditions, there may be substances that become organic matter, enter living things, and evolve new species.
What about humans? Humans cannot rule the planet forever. Humans have ruled the earth for about 1.7 million years.
However, for the 5 billion-year-old Earth, 1.7 million years is just a snap of a finger. If you take the development of the earth in a 10-minute movie, human beings only have about 3 seconds of footage.
Objectively aware of ourselves, we are inhabitants of the earth, not masters. The human category is too noisy to exist a little longer.
In the early years, there were many plants on the earth. Absorb CO2 in the atmosphere, transform oxygen, make human beings exist, ants on the earth eat plants, produce methane, in the future oxygen runs out, there are no plants, then there must be a creature that can use methane as a breathing creature to rule the earth.

Humanity will perish, but you can't see it.
Humans move, but you can't see it.

Mars has been modified to be inhabitable.

That's not something you should worry about.

As things stand, there is no sign that the Earth is going to be destroyed anytime soon. However, the day when the earth will be destroyed is also in accordance with the laws of nature, and no one can resist it. But how long can the Earth survive?
In what way will it eventually be destroyed or perished? No one has yet been able to make an accurate ** on this issue. But I'm sure those of us who are alive won't be able to catch up.
In addition, I personally believe that if the earth is destroyed, humanity will not exist. Because humans don't have the ability to move to other planets. And so far, astronomers have not found a planet in the solar system as suitable for human life as Earth, even Mars.
Far further into interstellar space measured in light years, which is even more unattainable for humans! Even if such a suitable planet can be found in the future, it will be extremely difficult for human beings to realize their dream of moving to other planets, let alone realize large-scale interstellar population migration! This is technically impossible and impossible!
Most of the rest of the population were left to fend for themselves on Earth.
Humans cannot destroy the planet.
Because, no matter how powerful human beings are, they can't really destroy the earth, as far as the current level of science and technology of human beings is concerned, human beings have not even reached the ability to destroy half of the earth, let alone destroy it, even if human beings have more nuclear **, but only the surface of the earth will be harmed. >>>More
The universe is so big, the existence of life should be very common, but it doesn't have to be like earthlings. For example, the body may not be carbon, not necessarily a physical entity, or even a three-dimensional form. The human imagination is too limited.
Then we can only build a spaceship and load some human beings to wander in the universe and continue to look for planets where they can live.
Perhaps many people are curious about this question: if one day in the future human beings disappear completely, what will happen to the earth? The conclusion should be simple, if it is long enough, the earth will erase all traces of human existence and return to its original state. >>>More
After death, people appear in quantum form. >>>More
