When Mark Zuckerberg does Townhall Q&As on Facebook to hear from users, he gets thousands of questions.
Sometimes famous people ask questions. On Tuesday, Stephen Hawking asked him a question.
"I would like to know a unified theory of gravity and the other forces. Which of the big questions in science would you like to know the answer to and why?" the world-famous physicist posted on Facebook through a verified account.
His question received over 6,000 likes.
"I don't think Mark would wanna answer this," one Facebook user joked. "Mr. Hawking wins the best question Q&A award," another quipped. "Epic, respect, legend," others commented.
Zuckerberg responded within minutes, saying: "That's a pretty good one! I'm most interested in questions about people. What will enable us to live forever? How do we cure all diseases? How does the brain work? How does learning work and how we can empower humans to learn a million times more? I'm also curious about whether there is a fundamental mathematical law underlying human social relationships that governs the balance of who and what we all care about. I bet there is."
