Very bad news for all of us: We will not survive another 1,000 years on Earth, says Stephen Hawking. One of the most brilliant minds warns that ‘we must continue to go into space for the future of humanity.’
‘Humans will not survive another 1,000 years on ‘fragile’ Earth.’
Professor Hawking at a talk at the Oxford University Union also insisted in space travel.
“I don’t think we will survive another 1,000 years without escaping our fragile planet. I therefore want to encourage public interest in space, and I have been getting my training in early.
I believe that life on Earth is at an ever-increasing risk of being wiped out by a disaster, such as a sudden nuclear war, a genetically engineered virus, or other dangers. I think the human race has no future if it doesn’t go to space.”
What would it look like to return home from outside our galaxy?
Although designed to answer greater questions, recent data from ESA’s robotic Gaia mission is helping to provide a uniquelymodern perspective on humanity’s place in the universe. Gaia orbits the Sun near the Earth and resolves star’s positions so precisely that it can determine a slight shift from its changing vantage point over the course of a year, a shift that is proportionately smaller for more distant stars — and so determines distance.
In the first sequence of the video, an illustration of the Milky Way is shown that soon resolves into a three-dimensional visualization of Gaia star data. A few notable stars are labelled with their common names, while others stars are labelled with numbers from Gaia’s catalog. Eventually the viewer arrives at our home star Sol (the Sun), then resolving the reflective glow of its third planet: Earth.
The featured video is based on just over 600,000 stars, but Gaia is on track to measure the parallax distances to over one billion stars over its planned five year mission.
