Plans to evacuate the Earth and plan a new humanity on another planet seem, without a doubt, science fiction. However, some scientists have already the eye placed on nearby planets to which human life could be transferred if something failed.
The impact of an asteroid, some climatic hecatomb or the evolution of the Sun itself and the boiling of our oceans can threaten humanity sooner or later. "Therefore, moving into space is the most advisable to extend the existence of humanity," warned Viva to the physicist. Avi Loeb of Harvard University.

It's not the first time Loeb has made surprising statements to the rest of the world. Months ago, he said an asteroid detected in 2017 could actually be the remains of an alien ship. He was also a friend of the popular astrophysicist Stephen Hawking, who before his death suggested the same thing: to find, as soon as possible, a new space home.
What could be the next planet for humanity to inhabit? For now, Next Centauri B, a small planet that orbits the star closest to the sun, is the first candidate. It's 4.25 light-years from Earth, and although it may seem distant, it's relatively close to talking about celestial bodies.
Next, Centauri B has a hemisphere always illuminated, subject to high temperatures, while the dark hemisphere is extremely cold. However, while Loeb is optimistic, other astronomers point out that bringing a living human to that planet would be extremely difficult.

"By optimizing a small probe (a few pounds) and with the propulsion we currently have, I do not think we could get there in less than 10,000 years. Anyway, there are preliminary phase designs for the construction of solar-powered Earth, who would be able to launch mini-instruments at great speed: they would arrive in less than 100 years " explains Guillem Anglada Escudé, of Queen Mary University, London, one of the discoverers of Proxima Centauri B.
For Loeb, getting there with the rockets we have today would take 50,000 years, but when it comes time to try to see humanity die, it will be worth it. Is anyone going to do this?
