Where will mankind go in the future?

Although the universe is boundless, the earth is still our only home. However, the earth will not be the eternal home of mankind. Before the appearance of human beings, five mass extinctions on the earth have warned us. If human beings want to exist forever, they need to leave the earth and find a new home in the universe. Of course, the solar system is also unreliable. Although emigrating from Mars is the most likely thing for us at present, in another 5 billion years, the sun will come to an end and cannot continue to provide a hotbed of life for mankind. So, where will the future of mankind go?

Abraham, a scientist at Harvard University, told us that in about 2 billion years, the sun will become hotter and hotter. Even if there is no mass extinction before that, the earth will no longer be suitable for human habitation. Moreover, as the sun enters the middle and late life, the sun's rays will become brighter and brighter, and all kinds of radiation will become very intense. The earth will not only be scorched, but also the atmosphere and oceans will cease to exist, and there will be no more life on the earth.

Considering that the supernova explosion in the later stage of the sun may spread to other surrounding galaxies, we should not only fly away from the solar system completely, but also stay as far away as possible. Centauri will not be our home, we can at least find our other home dozens of light years away. However, the problem is that human life and speed are not enough to support our arrival. Therefore, the first thing we should do is to find a shortcut (wormhole) in the universe or fly at the speed of light.

However, the earth has a huge population, and even if another earth is found, it is impossible to emigrate globally, and it is absolutely impossible to build a spaceship that can accommodate billions or more people. What about The Wandering Earth? This is obviously not feasible. Science fiction films are just science fiction films.

Scientist Abraham thinks that maybe in the future we can build a new earth in the universe through gene replication. As we have seen in many science fiction films, human beings arrive at another planet with the fire of life, and then inject life into other planets. But in doing so, very few people will be lucky enough to leave the earth, and most of the rest may not be able to leave, so they can only wait for the day when the sun is destroyed on the earth.

Of course, we need not be too pessimistic. After all, there are still billions of years. Before this, perhaps human science and technology have already developed into a super civilization, and we are no longer bound by life, or we have successfully discovered wormholes and can travel between stars at will, just as it is convenient for us to travel on the earth now.

It is also possible that in the future, human beings will no longer be bound by material bodies, and each of us will become conscious bodies. This is also a state that many scientists believe that human beings will eventually evolve into. At that time, we only need a supercomputer to accommodate everything, and then we can really come and go freely in the universe. What do you think human beings will become in the future? Will humans successfully fly away from the earth and realize interstellar migration?
