You killed it again in the 'explain in layman's terms' department, with that paper on the globe.

Dianna, what kind of conditioner do black holes use

That blackhole animation is sick! Would make a great lockscreen animation

"Let's bring it back to black holes. See, they're inescapable." That joke was fantastic 🤣🥁

“Gravity is what happens when you walk straight on a non flat thing” what an absolutely incredible line.

If you were my teacher in school I would probably have understood 90% more of what I was hearing in class. These are so well done.

2:12 I love that photo of Einstein cuz I tell myself he wrote "LOL" on the blackboard :')

When I studied physics at university, every single lecturer was male. So was nearly every student. I'm so happy that this is changing. My daughter has people like this young lady to inspire her.

4:13 what an extremely distinguished group of characters

RIP to the man who studied, but never saw one himself.


We all owe you Professor... Thanks Mr. Hawking, I hope you can now see it yourself from above.

Dianna- "Not even a thank you note" rude!
Me - 😂😂😂😂
I extremely love this type of craziness!

Thanks for showing a straight line on a sphere. That was an amazing display of curved space.

Whose here after 10th April's first black hole picture

Outstanding video Dianna. As usual, you provided cogent thoughts, your delivery was engaging and your enthusiasm contagious. Love your work and I think you are outstanding in your field along with Derek, and the Green brothers.

This is actually an old theory proposed earlier by his collaborators. It's called the holographic principle. Gerard t'Hooft and Leonard susskind wrote about this.

I now need a shirt that says, "I can't walk straight".

Stephen has been a big influence to me, and a big inspiration too. I loved him and his work, and I'll always try to use his theories in any way I can. I love that people are finishing and publishing his infinished work, even in 2020

[upandatom]

It's great to have you back. Your demonstration skills are to be envied (globe and paper thing)

Glad to finally hear someone say "density" instead of gravitational mass or critical mass. When talking to people not familiar with physics, I always put it that way.
