Neutron Stars – The Most Extreme Things that are not Black Holes

Neutron stars are one of the most extreme and violent things in the universe. Giant atomic nuclei, only a few kilometers in diameter but as massive as stars. And they owe their existence to the death of something majestic.

"No one knows for sure and that's why we do science."

I need that on a tshirt.

[obviouslymatt]

did you just try to sell a calendar using an existential crisis?

i love it.

[jonstarks]

I like how the people who named the layers of the neutron star were just like “wow, I sure am hungry, and the effects of gravity on these atoms sure do remind me of Italian cuisine.”

[vice.nor.virtue]

I'm really happy that Kurzgesagt remade this video. I already thought that their original video on Neutron Stars was brilliant, but it seems that enough progress was made in both science and the development of this channel that they felt it necessary to have another go at making an improved version- and what a corker it is! There was no mention of _nuclear pasta_ in the last one for sure!

"No one knows for sure, and that is why we do science."
Love it.

Imagine having the ability to literally fold time like a piece of paper and still only being the second most powerful thing in the universe.

[ThePoltergust]

It's wild to me that something so ridiculously, incredibly extreme could have irregularities in its surface at all, let alone "a few centimeters high"-- the idea of a neutron star, this impossibly dense ball of particles, could have a surface rough enough that you could actually hypothetically _see_ its irregularities with the _naked eye, _ is mind-boggling to me. I would have imagined it to be completely uniform

[harbirsingh]

This is my favourite Kurzgesagt video and I've watched it at least 7-8 times by now. Blows my mind every single time.

[pedroscoponi]

"science terminology is way too complicated!"
>Neutron stars are made of atomic spaghetti and lasagna

[arypramana]

"pasta is the strongest material in the universe"
The entire population of italy: *mamma mia...*

[soflou]

8:06 As a huge lover of space and astronomy, this one hurt. Deep.

[xenon]

At 7:13 the album cover is actually a graph of times where a pulsar was facing earth that the band thought looked cool, so they put it as their album cover

[TheHumanEwok]

"not only do they have to die, they have to die twice"

*James bond theme starts playing*

[flikflac]

Test question: What is a neutron star?


Answer: A spinning ballerina made out of pasta that has to die twice

[Flakester]

This is the video that actually got me interested in space videos on youtube 4 years ago. Crazy to see it come back through my feed.

*To the Kurzgesagt translator for the channel's Spanish subs* :

There's a *massive mistake* in the Spanish translation that's repeated in every video: numbers beyond 1 billion are always wrong, as they aren't converted from short scale (used in English) to long scale (used in Spanish): thus, "billions" are wrongly translated into "billones", "trillions" into "trillones", etc. Those are _false friends_ because, actually, 1 billion [in English] = 1000 millones [in Spanish], NOT "1 billón"; likewise, 1 trillion in English = 1 billón in Spanish; and so on.

These mistakes are present in every Kurzgesagt video I've seen with Spanish subs and therefore the quantities are wrong by a huge order of magnitude. Please correct them so people don't get the wrong info.



*[Explanation:]* This is because Anglo-Saxon countries use the "short scale system", while Hispanic and continental-Europe countries use the "long scale". In the first case, "one billion" means "a thousand millions" (1, 000, 000, 000), whereas in the long scale, "one billion" equals "a million millions" (1, 000, 000, 000, 000), also called "a milliard". The Italian subs, for example, got this right and translated the English word "billion" into "miliardi".

(The only correct translation in this video is "1 million" to "1 millón", since both scales coincide in using that same word for the number 1, 000, 000.)

Kilanova is literally the most metal thing I've ever heard.

“Nuclear pasta is possibly the strongest form of matter in the universe”

*THE ITALIAN MILITARY WOULD LIKE TO KNOW YOUR LOCATION*

[AyoKembali]

I love how this channel give us the illustration through animation. So it's easier to understand.
