The Largest Black Hole in the Universe - Size Comparison

Sources & further reading:

The largest things in the universe are black holes. In contrast to things like planets or stars they have no physical size limit, and can literally grow endlessly. Although in reality specific things need to happen to create different kinds of black holes, from really tiny ones to the largest single things in the universe. So how do black holes grow and how large is the largest of them all?

The Black Hole story continues with our Black Hole merch, spanning the whole range from somewhat bonkers to more serious.

These videos hurt my brain. I love it.

[NorthoftheBorder]

Ah, my monthly dose of existential dread in adorable cartoon bird format.

[SKPetel]

every single science channel should adopt your "behind the lies" epilogue format. this is how you improve science literacy while still making an entertaining video. As always, top-notch job.

*Quick Update:*
This video was produced 2 years ago. As of January 2024, the largest black hole is Phoenix A

THE MUSIC WITH THE SIZE COMPARISON AT THE END WAS SO INTENSE

[IntroSpecktive]

Hearing that dark matter could be microscopic black holes that are nearly as old as the universe itself was a mind blow that I wasn't prepared for.

[NguyenMinh]

9:50 the music syncs really well with the greatness of the universe

[metroschannel]

Your art and animations are very inspiring for a creator like me. Your color pallet is so relaxing to look at, I can tell a ton of time has been spent on getting the colors right alone.

[Phalanx]

So in the grand scheme of things, paying my taxes doesn’t matter.

[waterlemon]

The weirdest thing i’ve heard today is that a tiny blackhole named “unicorn” is bullying a star many times the mass of our sun

[aGratDy]

This is probably my favorite video so far from your channel!
Excellent stuff!

[zilve]

I am not gonna lie. This is my top 1 youtube video. I keep coming back to it every few weeks. Kurzgesagt, I love what you do <3

[Asif_Whatever]

13 minutes of “This isn’t even my final form”

[dustinlarkin]

I've always been fascinated by space. Seeing one of those explosions up close and somehow surviving would be the ultimate experience. Or seeing a black hole from the least safe (but still safe) distance would be incredible. Seeing then collide would be the coolest thing ever.

[carlosizz]

I've gotten used to universe size scale, what melts my brain is the absurd brightness generated by these objects. Great video.

[philm]

The "Behind the Scenes" portion is the best thing ever. Thank you for treating us like adults. Reality is complicated.

[wishiwasabear]

The boss music when moving up to ultramassive blackholes was a nice touch

[desertlovesyou]

Shout out to Epic Mountain who does the music for their videos! Thank you for creating equally enjoyable music to go along with these wonderfully made (and narrated!) videos!

[tiybklj]

You guys are awesome! Even having the idea to make the video was amazing! But I have another question. What is the most biggest galaxy in the world?
