Black hole singularities break physics - fortunately, the universe seems to conspire to protect itself from their causality-destroying madness. At least, so says the cosmic censorship hypothesis. Only problem is many physicists think it might be wrong, and that naked singularities may exist after all.

[BaghNakh]

Instructions unclear, now I have an event horizon without a singularity.

[CarthagoMike]

What to do when you got time to spare due to lockdown:
1. -find a way to order bread-
2. -work from home-
3. *find out how to dissolve an event horizon for the sake of breaking physics.*

[joen]

I’m sick and tired of these YouTube videos telling me not to try this at home. If I want to try to dissolve an event horizon, I will and you can’t stop me. All I need is a salad spinner, electric tape and a can of peaches.

[namr]

I read a comment on a similar type of video saying "Of course they exist, i get notifications about naked singularities near me all the time." and now I can't keep a straight face anytime I hear the word.

[hinkles]

Matt: "Black holes are their own space-time."
Me: You mean time-space.

[grah]

Me: *understands episode perfectly for once and starts really wanting to see the defined state of a naked singularity*
Matt: "You'll have to wait..."
Me:

[nziom]

imagine doing something so illegal so bad that the universe itself physically censeore you

[avoirdupois]

"We apologise for the inconvenience." Always makes me smile. This is amazing content. Thanks for being an eloquent spokesperson, and thanks to the crew for the amazing graphics to help it to make sense.

[bignubthebobby]

Matt has gone so deep within physics that if you haven't watched along, you'll have to watch everything before any of this makes "sense".

[likebot.]

In a world inside a black hole: "... in some cases even space-travel is possible. Causality breaks down."

[Itachix]

In a Black Hole it's "PBS Time Space"

[BaseDeltaZero]

Just want to say that Matt and the entire PBS/ST team have done an absolutely sterling job of bringing us our regular fix of science and space during the lockdown...with no real drop in quality either.

Stay safe and stay awesome guys!

[tomduke]

how to spot theoretical math: there is an infinity in there, which is the mathematical equivalent to "idk, probably a lot"

[mindblow]

Inside the black hole:
*PBS Time Space* : Hello, this is Black hole, and we will talk today about Naked Matt O'Dowd singularities

[sirkowski]

1:09 The naked singularity sounds like an Eldritch Abomination.

[MichaelSkinner-ej]

That’s the one thing always wanted to talk about was regular black holes versus spinning black holes (evaporation)

[michaelblacktree]

PBS Space Time: How to dissolve an Event Horizon
John Michael Godier: WAIT A MINUTE

[gavxmas]

It's taken years, countless rewatches and 0 formal study but I'm no longer lost and curios, I'm actually starting to keep pace with all this. Can't do the math but I can understand the implications results and theories they create!

[kaigreen]

I do hope people wrote "so long, and thanks for all the fish" and not "goodbye..."

[Tokahax]

I cannot describe how much this series means to me. Thank you.
