Stephen Hawking: Mankind could wipe itself out in 100 years
Answering audience questions at this year’s BBC Reith Lectures, Prof Hawking said that our rush to understand and improve life through science and technology could be humanity’s undoing.
He has previously suggested that colonising other planets will be the only way that the human race can survive, but he warns that we may lose Earth to some kind of major disaster before we have a chance to do so.
