EXCLUSIVE: Stephen Hawking on What Existed Before the Big Bang

In this exclusive clip, Tyson asks Hawking your standard softball interview question: what was around before the big bang? In other words, what happened before the moment the universe began? Check out Hawking’s answer:

“The boundary condition of the universe...is that it has no boundary,” Hawking says.

Stephen was given a couple of years to live, in 1963. *But he outlived the doctor who told him that.*

Peace, brother.

It's really hard to imagine nothing existing. Like our brains really can't process the infinite like that. Crazy

"I adopted a euclidean approach to quantum gravity to describe the beginning of the universe"

Oh yeah...well I mopped my kitchen floor.

This guy in a wheel chair has accomplished more than my entire family lineage going back thousands of years, lol.

Rest in peace dear Stephen. You were an example of what humans could be. There won't be another like you.

[David_Bower]

He left the world a better place for his existence.

[DaFlyingStrawberry]

That was really confusing right up until the last sentence. A mastermind of explanation

Sad that Stephen Hawking would be gone in just 12 days after this was uploaded even though I don't know when this interview actually took place. He was one of the biggest scientific icons since Albert Einstein, RIP.

Asking "what was before the big bang" is like asking "what was before time"

[MackV]

You'll be forever missed... R.I.P

[Anonarchist]

since time is movement through space, there couldn't have been time before space. it's like asking what was the first thing you did before your parents conceived you.

[bzkairos]

Such a brilliant person. Thank you for your contribution to science. Rest in Peace.

[henrybills]

Stephen Hawking is the man who made me the nerd I am today. Many has singers as heroes or idols. Stephen is mine idol and hero. I love him! Many times I dont understand a single word of what he say but he made me at aw of the universe and what was, what is and what to be in the universe. My love for the universe is big thanks to him. I just NEED to know more. When he died a part of me died.

[Hannah-zuvv]
