Has Stephen Hawking Solved a Black Hole Paradox?

Stephen Hawking recently announced that he’d come up with an answer to one of the biggest questions in physics. But it’ll probably be a while before we know exactly what it is.

Winning a science related bet with Stephen Hawking must feel like an honor

[BlinkyLass]

The problem with describing theoretical physics to laypeople is that all the mathematical foundation is left out because it's beyond most people, and explanations end up sounding like philosophy. Unfortunately, some misguided people then think they've understood it from hearing simplified accounts. This turns physics into a crackpot magnet. While it's not a problem unique to physics, the field seems to suffer the most from this issue because of the vast divide between popular conception of physics and how people actually work in physics.

A photon walks into a hotel and asks for a room. The concierge asks if he has any luggage. "No, I'm travelling light." Badaboom-tish :D

"Has Stephen Hawking Solved a Black Hole Paradox" is a weird title for this.

A more accurate title would be:
"Does Hawking finally accept he's wrong about black holes destroying information and now agree with Susskind's holographic principle"

This is not hawking's idea (as you mentioned later in the video)

The information that enters my brain, the night before exam also vanishes as the exam begins... Its forever lost 😂😂😂😂😂

[VegetoStevieD]

1. Can anyone explain to me why information has to be stored in a way that a historical timeline can account for it? Can it not just be outside of the "before-during-after" sequence of "something entering a black hole"?

2. If information can't disappear completely, then couldn't it just be displaced? Why does it need to be stored anywhere near the black hole? If a 1 or a 0 disappears at a black hole, then perhaps a 1 or 0 pops up somewhere else to replace it?

3. Is it possible that something can't actually be entering a black hole, because it is already there? Maybe there is a fundamental problem with the angle in which black hole problems are being addressed, and the math will work once they stop asking the wrong questions.

Just questions.

Thanks for mentioning Gerhardt and Leonard. Without their tenacity Hawking would have kept the physics community from considering this more advanced and accurate model.

how to connects internet history to black hole?

baseball encyclopedia?
there's some really REALLY inside joke here isnt there.

[Infinite_Omniverse]

I was so excited when I heard about this!

[holz_name]

Except that all is highly theoretical. We never observed Hawking Radiation, and we probably will not observe holographic black holes in the next 1000 years. Don't get me wrong, Stephen Hawking is a great scientist and probably he is on the right track, but the time to declare something as "solved" is when we can experimentally test it. So, it's really lots of hype around Hawking.

I read the black hole war in 7th grade and it is still my favorite book on physics today. Incredibly well written, funny, interesting and everything is well explained. A great read about awesome people.

[billsmith]

So basically he didn't solve anything, he just changed his mind and used another persons' principle lol

[billdong]

You proved the most famous living theoretical physicist wrong, here is a baseball encyclopedia as your reward.
I guess solving the puzzle of the universe isn't the only thing these people are awesome at.

JUST FOUND THIS CHANNEL! Why have I been living under a rock? I must watch every video!!!

[karkinissan]

Sees on social media " Steven a dozen times.
Meh, I'll just wait till scishow covers it.

[LelekPLN]

What do you mean it was a mystery? I thought it was common knowledge that when you enter the black hole you end up in a little girl's 5D bedroom... HELLO!?

[jarradpearman]

basically stephen hawking accepts a concept that has been around for 20 years and somehow it's now valid because he says so, why world?

[lordvivec]

Why would the information be lost though? I was under the impression that a black "hole" was just a massive enough ball of matter to be able to suck anything, including light, into it with no hope of escape. So would all the matter and information still be there, just in the ball? Sure we can't access it, but the information is still there.

It would be great if an expert happened to come across this and set things straight.

I'de love to learn about how gravity effects the way light (or EMR) moves. I thought it didn't affect it at all and if it didn't how could the gravity of a black hole stop the light from escaping? Thanks
