Stephen Hawking shared his thoughts on singer Zayn Malik's exit from popular boy band One Direction at a talk at the Sydney Opera House Saturday night.

Hawking, a renowned physicist and author of "A Brief History of Time," appeared as a 3-D hologram from his physical location at Cambridge University to discuss his work and answer questions from the audience.

"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?" asked audience member Samantha. Malik left One Direction last month, saying, in a statement posted on the band's Facebook page, "I am leaving because I want to be a normal 22-year-old who is able to relax and have some private time out of the spotlight."

"Finally, a question about something important," Hawking replied amid laughter from the audience. Hawking advised heartbroken One Direction fans to look toward theoretical physics for consolation.

"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," Hawking said.

"This girl may like to know that in another possible universe, she and Zayn are happily married."
