Forget about the 'theory of everything', an even more important question has been put to Professor Stephen Hawking - What do you think is the cosmological effect of Zayn Malik leaving One Direction? The legendary physicist was speaking at the Sydney Opera House as a 3D hologram from his physical location at Cambridge University in the UK, when the question was put to him. But it was a subject that Professor Hawking had his own theory on saying: 'Finally, a question about something important.' Scroll down for video . Professor Stephen Hawking appeared at the Sydney Opera House on Saturday night as a 3D hologram from his physical location at Cambridge University in the UK . During the show Professor Hawking was asked about the cosmological effect of former One Direction singer Zayn Malik leaving the boy band . Buzzfeed reports that a questioner asked: 'What do you think is the cosmological effect of Zayn leaving One Direction and consequently breaking the hearts of millions of teenage girls across the world?' But he happily tackled the conundrum and came up with an explanation that would satisfy every One Direction fan. 'My advice to any heartbroken young girl is to pay close attention to the study of theoretical physics. Because one day there may well be proof of multiple universes,' he said. Professor Hawking showed as well as a huge intellect he possesses a good sense of humour . When Zayn left One Direction he broke the hearts of millions of teenage girls . Professor Hawking joked that in another different universe 'Zayn is still in One Direction' 'It would not be beyond the realms of possibility that somewhere outside of our own universe lies another different universe. 'And in that universe, Zayn is still in One Direction.' It got better still for the questioner as Professor Hawking went on to add that, 'this girl may like to know that in another possible universe, she and Zayn are happily married'. The legendary physicist also spoke about the mysteries of the universe, being diagnosed with ALS, and the future of our planet . Apart from the cosmic effect caused by Zayn leaving One Direction, Professor Hawking spoke about the mysteries of the universe, being diagnosed with ALS, and the future of our planet. And if the future of mankind was to prosper then we had to look to the stars. 'We must also continue to go into space for the future of humanity. I don’t think we will survive another 1,000 years without escaping beyond our fragile planet,' Hawking said.
