Physicist Stephen Hawking's 5 groundbreaking predictions

We have only 100 years left on earth

Hawking had predicted in 2016 that humans have 1,000 years time limit on this palnet. Last year he reduced that horizon exponentially—100 years left, he warned, unless we changed our ways.

According to Hawking in his BBC science series, Tomorrow’s World, climate change, overdue asteroid strikes, epidemics and population growth are to blame for the new century-long doomsday clock.

Earth will one day look like Venus if global warming continues

In July, Hawking told the BBC that humanity is at a “tipping point” where global warming would become so bad that Earth will “become like Venus, with a temperature of 250 degrees celcius, and raining sulfuric acid.”

He also commented about President Donald Trump's decision to withdraw from the Paris Climate Agreement has doomed our planet. Hawking's said, Earth will one day look like the 460°C (860°F) planet Venus if we don't cut greenhouse gas emissions.

Hawking's said, 'Next time you meet a climate change denier, tell them to take a trip to Venus. I will pay the fare.'

By the year 2600, the world's population would be standing shoulder to shoulder

The renowned physicist believes soaring population sizes and increasing demands for energy will lead to the catastrophe. In 2016, November at a Tencent WE Summit, he predicted that the global population has been doubling every 40 years, and our planet can only take so much.

Hawking also explained, “This exponential growth cannot continue into the next millennium."

Artificial Intelligence as threat to humanity

“Earth is becoming too small and humanity is bound to self-destruct, with AI replacing us as the dominant being on the planet,” he told wired.com in November 2017.

“I fear that AI may replace humans altogether. If people design computer viruses, someone will design AI that improves and replicates itself. This will be a new form of life that outperforms humans,” Hawking said.

Donald Trump could push earth over the brink

Stephen Hawking said, "Climate change is one of the great dangers we face, and it’s one we can prevent if we act now. By denying the evidence for climate change, and pulling out of the Paris Climate Agreement, Donald Trump will cause avoidable environmental damage to our beautiful planet, endangering the natural world, for us and our children."
