As the impacts of climate change, diseases, and artificial intelligence is gulping human-hood, renowned physicist #Stephen Hawking has given a tall order stating that we have only #100 Years left to colonize another planet to survive the disastrous effect.

Stephen Hawking gave this warning in a documentary named "Expedition New Earth" - part of BBC's new science season, "Tomorrows World." In the documentary, Hawking claimed that time is running out for humans, and to survive; it is very much necessary to find another habitable planet.

Many problems awaiting the humankind

In the documentary, Hawking listed some very noted causes which may end up in human extinction.

Stephen mentioned uncontrollable global warming, asteroid hits, nuclear war and adverse impacts of artificial impacts as the most noted causes which may end human life on this planet. Earlier, Hawking had warned all the world leaders telling that humanity will be destroyed either by a nuclear or biological war.

The scientist also hinted that artificial intelligence may overtake #Humans in the evolutionary race and will end the dominance of us on Earth. He also mentioned that humans do not have that extra ability to survive during hard times.

Is Space colonization a reasonable step?

The concept of space colonization is a challenging yet achievable goal which humans can think about as the future is turning more darker.

Many scientists all across the globe are analyzing various ways by which Mars can be colonized in the next thirty years.

Space agencies and experts believe that the red planet is a perfect destination for colonization in our solar system, as it has favorable surface conditions and the presence of water. As Stephen Hawking has warned about a possible extinction, the idea of space colonization is expected to gain more pace in the coming days.

A group of scientists believes that Venus is also a prospect planet which can be considered for migration, as its bulk composition and gravity are similar to that of Earth. But in this race, Mars always has the upper hand, as its solar day is very identical when compared to our planet. A complete solar day on Mars is 24 hours and 39 minutes. The planet also holds water ice which is a very necessary constituent for survival.

NASA believes that their inflatable greenhouse could produce Oxygen and food on Mars, and this will be the primary weapon for humans while surviving on the red planet. Scientists have also succeeded in manufacturing small bricks using the Martian soil.
