Life on our planet depends on the intensity of the Sun. However, astronomers have studied numerous stars throughout all of their life stages, and it seems that in a couple billion years, things will get pretty heated in our solar system. When the temperatures will rise the oceans will boil, and all life will disappear. Or will it? What do scientists think will happen to humans when Earth becomes uninhabitable?
According to Lisa Kaltenegger and Ramses Ramirez, humankind will be able to survive on more distant grounds. Mars isn’t the only possible new home for humans. Jupiter’s moons Enceladus and Europa are both perfect for hosting life in the event in which the Sun starts shining brighter.
Scientists have discovered that Enceladus and Europa both have warm, dense cores that will generate just the right amount of gravity. Furthermore, Enceladus even has massive frozen water deposits that, in the case of a warm up, will turn into an ocean that will take over the entire satellite. Just imagine Bora Bora, only on the whole moon.
The most exciting part of this scenario is the fact that the heat wave could bring back to life all of the organisms that are currently under the ice on Enceladus and all other planets that have not seen a warm ray of sun in millions of years.
However, if Earth becomes uninhabitable in a couple billions of years, humans may not be limited just to the planets and satellites within our solar system. NASA is already planning to send a manned mission to Mars in 14 years; Stephen Hawking is working on an array of minuscule probes that will explore outer systems, searching for additional signs of life.
It’s not impossible for them to find uninhabited Earth-like planets where humankind will be able to move once our Sun starts to turn our world into an uninhabitable wasteland.
Currently, astronomers have discovered 23 red giant stars that are only 100 light-years away from our solar systems. In a couple of billions of years, researchers will certainly find thousands upon thousands of systems capable of harboring human life.
Moreover, at the rate in which technology is advancing, humans might just build their own planets by the time Earth becomes uninhabitable.
