"The Universe is under no obligation to obey our preconceptions. "

That's beautiful and terrifying at the same time.

@Elrond_Hubbard_1

I've got it.

The only way to survive falling into a black hole is to be made out of spaghetti, because if you already are spaghetti, how can you be spaghetified?

@MrInitialMan

"The core of the star is about to go bye-bye."  My FAVOURITE line in this series.

@sid670

If I had to fall in a black hole, I'd do it twice. Once looking directly at the black hole, and once looking out into space.

@Filippirgos

Today the history was made, the first picture of a black hole ever has been captured !

@TheFireflyGrave

Black holes, The Event Horizon, and Spaghettification.  Astronomers really know how to name stuff.

@WhosFaulty

new uploads from this series is my favourite time of the week

@kem8609

I'm not even watching this for a class I just love astronomy and our school in Ohio doesn't provide the course :(

@chibinyu1548

"The universe is under no obligation to obey our preconceptions.." The best quote ever! <3

@dorkmax7073

Only 4 years after this video was released, a team was able to composite an image of Messier 87 and it's supermassive black hole. We are an incredible species

@Connarthian

Actually, I think that falling into a black hole is somewhat a romantic idea now. Falling in, I would see everything happen. All of the future. The price is life. That's frickin' deep man.

@ffggddss

Phil: Thanks for the incredible ride!

Just two things I might (or might not) add:

1. Tidal "spaghettification" is just as much about transverse compression as it is about longitudinal stretching.

2. An alternative, and perhaps even neater way to explain the inability of anything escaping from inside the event horizon, is that while outside it, the radial direction is spatial, inside it, the radial direction is time! And forward in time points toward the central singularity. So escaping from inside, is exactly the same as traveling backward in time!

@tarvingill1777

I've watched this episode and the episode about the Sun about 50 times ... please never end this series .. and make sure Phil does all the shows.. he is incredible ☺ thanks

@joshuahellauer2400

Ok, the gig's up. We know you're Vsauce's brother.

@CrimsonDragon15

There is absolutely nothing that I love more about Astronomy than learning about Black Holes. My favorite subject. By far the most complex and fascinating thing about the universe.

@zamane1234

"Bloop,gone."That was my favorite line

@emoore29681

Thank you, Phil, for uttering what is possibly the best thing I've heard all week: "It turns out, none! None more force! The core of the star is about to go bye-bye."

@f4u1g2d9

I can not believe that these "CrashCourse" postings have been going on for years and I did not know it. Since discovering them a few days ago, I've been watching a couple every day! This explanation regarding black hole gravity and "Escape velocity at the surface being equal to the speed of light" made a light go off in my head. Love this channel.

@Aziz-ev1ez

Black holes are still brighter than my future

@AbdullMohommedlol

space is just so interesting and awesome
