Stephen Hawking left his final warning to humanity before death — we must leave the Earth

The late physicist made a strong warning to human beings if they wanted to survive. A few months before his death he warned that man wouldn’t survive here on Earth after 200 years.

Movies that have shown humans looking for other planets to live on are one of the things Stephen Hawking wanted people to do. According to Daily Mail, there were some other factors that could destroy the Earth.

Stephen Hawking believed that human beings only had 2 more centuries left on this Earth. The physicist believed that life on Earth could be wiped out by a disaster such as an asteroid strike, Artificial Intelligence or an alien invasion.

He also warned that over-population, human aggression, and climate change could cause humanity to self-destruct. Hawking encouraged man to abandon Earth and forge a new life in space.

Hawking's main fear for the planet was global warming. In July 2017, he warned that our physical resources were being drained, at an alarming rate.

He stated that humans had given our planet the disastrous gift of climate change. The scientist shared that we were responsible for rising temperatures, reduction of the polar ice caps, deforestation, and the decimation of animal species.

He said that Earth would one day look like the 460°C (860°F) planet Venus if we didn't cut greenhouse gas emissions. The physicist also believed that President Donald Trump's decision to withdraw from the Paris Climate Agreement had doomed our planet.

'If we succeed we will send a probe to Alpha Centauri within the lifetime of some of you alive today.’

The famous scientist believed that if global warming didn't wipe us out, Earth would be destroyed by an asteroid strike. He stated that it wasn’t science fiction but something that was guaranteed by the laws of physics and probability.

Hawking was working with Russian billionaire Yuri Milner to send a fleet of tiny 'nano craft' carrying light sails on a four light-year journey to Alpha Centauri. This is the nearest star system to Earth.

Astronomers estimate that there is a reasonable chance of an Earth-like planet existing in the 'habitable zones' of Alpha Centauri's three-star system.

Hawking claimed that AI would soon reach a level where it would be a 'new form of life that will outperform humans.' He believed that AI may replace humans altogether according to Wired.

Hawking stated that if people could design computer viruses, someone would be able to design AI that improves and replicates itself. He shared that this would be a new form of life that outperforms humans.

In 2015, Hawking spoke to an audience at the Science Museum, where he said that the human failing he would most like to correct was aggression. The Independent wrote at the time that Hawking said aggression may have had a survival advantage in caveman days, to get more food, territory or a partner with whom to reproduce.

But now it threatens to destroy everyone. He feared that evolution had 'inbuilt' it into the human genome, commenting that there was no sign of conflict lessening.

The scientist also warned that if we ever did find aliens they would probably wipe us out. Gliese 832c is a planet that people speculate could be home to alien life.

Hawking said that one-day humans might receive a signal from a planet like Gliese 832c, but he pleaded with human beings to be wary of answering back. He revealed that meeting an advanced civilization could be like Native Americans encountering Columbus.

The renowned scientist also warned that a man-made catastrophe could be the end for our species. He told The Guardian in 2016 that humans faced huge environmental challenges including overpopulation.

Hawking warned that humans could not survive another 1,000 years on 'fragile' Earth. He shared that he thought that the human race had no future if it didn't go to space.
