THE human race is entering the most dangerous 100 years in its history and faces a looming existential battle, Stephen Hawking has warned.
And the 74-year-old said that as we rapidly advance in these fields, there will be “new ways things can go wrong”.
We are at a point in history where we are “trapped” by our own advances, with humanity increasingly at risk from man-made threats but without technology sophisticated enough to escape from Earth in the event of a cataclysm.
“By that time we should have spread out into space, and to other stars, so a disaster on Earth would not mean the end of the human race.
He added that humans do have a knack of “saving the day” just in time, and urged fellow scientists to continue trying to make advances in their respective fields.
Prof Hawking said: “We are not going to stop making progress, or reverse it, so we have to recognise the dangers and control them. I’m an optimist, and I believe we can.
“In a democratic society, this means that everyone needs to have a basic understanding of science to make informed decisions about the future.
“So communicate plainly what you are trying to do in science, and who knows, you might even end up understanding it yourself.”
