Over last several years, scientists on a regular basis have warned about the potential threats of extinctions due to ongoing climate changes. Stephen Hawking for a long time now provided different doomsday theories ranging from AI to climate changes. Most recently, the renowned physicist has warned that we may have less than 600 years to leave earth due to overpopulation and rising energy consumption.
Hawking’s latest warning came during his video video appearance at Web Summit technology conference in Lisbon, Portugal. At the summit, he said that if human race has to survive, then we will need to relocate to another planet where no one has gone before.
As we have known for a while, in order to do that, we will need ultra-fast spacecraft and Hawking revealed some details about one of the futuristic projects, Breakthrough Starshot initiative. The space program aims to develop an ultra-fast spacecraft that can accommodate humans to worlds circling around the nearby star, Alpha Centauri.
He said, “Such a system could reach Mars in less than an hour, or reach Pluto in days, pass Voyager in under a week and reach Alpha Centauri in just over 20 years.”
“Maybe if all goes well, sometime a little after the middle of the century, we’ll have our first picture of another planet that may be life-bearing orbiting the nearest star.”
