Atoms as Big as Mountains? - Nuclear Engineer Reacts to Kurzgesagt

Thanks so much for watching! For more on neutron stars, please check out:

You need to see "How to count past infinity" by Vsauce

So if you consider a neutron star an atom with a crazy high atomic number and orbit another one close to it so that the sea of electrons can pass between them, would that be considered a chemical bond and a molecule as big as two mountains?

[Gin-toki]

And to think it can get even wilder than a neutron star or pulsar, we have quasars, which makes the other pale in comparison :P
And congrats on 100K subs! \o/

"less of the timey wimeyness distortions"
Not that much less! A sufficiently dense neutron or quark star would let you see a blueshifted convex sky with sidereal time running in fast motion. Fast rotating neutron stars might have time doing even stranger things.

[petersmythe]

Note that rotating Neutron stars don't always deform outwards. If they are compact enough, they may form a photon sphere. A region of space so deformed by gravity that centrifugal force inverts inside, and the star's surface is concave, while the sky is convex. A rapidly spinning star under such conditions will behave very, very strangely, with its spin actively pushing it inward instead of outward.

Iron does fuse, but the energy released by the fusion of iron is less than that, which is present in any star, and only after a star goes super nova do we get heavier elements...

[DrKaufee]

It’s not that you can only fuse up to iron, it’s that iron is the point where the fusion starts requiring more energy than it releases

[Yaonglol]

Congratulations on 100k subs!!! It's been a wild ride so far and I'm excited to see more from you. One of the best and informative reaction channels out there right now.

[petersmythe]

"I wonder what terminal velocity on that thing is like"
Given that there's no dense atmosphere more than centimeters from the surface, very very high. If you meant escapes velocity, also very very high. Potentially approaching light speed.

[Yezpahr]

Yea I wanna hear more about neutron stars.
How do all the protons in the star turn into neutrons? Do they just get bombarded with electrons? How efficient is this process and is the extra size of the neutron also responsible for the powerful bounce that happens in an exploding star? (and yea those aren't neutron star questions, but I still wanna hear more about neutron stars :P )

Have you been recomended CGP Gray yet? You might like his video about Tekoi, a test site for Trident missile motors.

Radiation pressure is not strictly true alone either. Yes it is a factor but you also have just run of the mil pressure adding a regulatory effect too. If the reaction rate and compression increased eg because gravity was slightly dominant at a given time both of these will increase core temp also. That will increase the run of the mill thermal pressure exerted by the hotter denser plasma in the core too. Ultimately this is kinda how stars especially large ones remain so stable while the dominant process driving their core is constant if fusion accelerates it causes an expansion in volume and reduction in pressure reducing fusion rate. Also explains a lot why stable is a relative term for stars they all have cycles of oscillation as the forces nudge it towards a balancing balancing point but it oscillates around it.

[ThatJay]

i haven't watched the video yet, but the thumbnail/title kinda makes me think of neutron stars. this is a stretch, but could a neutron star be considered to be in some ways to essentially be one giant atom, just with gravity as its extra binding force to make it possible?

[edwardwoodhead]

You should check out the episode on Mythbusters where they see if cockroaches can survive a nuclear apocalypse.

[predrik]

I thought the atom comparison was because neutron stars are massive atomic nuclei as big as mountains? Not sure

[HmmmmmLemmeThinkNo]

I'd thought they were going to talk about highly theoretical elements x.x

[coolkid]

Hey! You should check out “The Chernobyl Guy - How Chernobyl Exploded” his new series of three videos going in depth into the actions in the control room of reactor 4 leading up to the disaster, I think it would be interesting to hear your thoughts!

[kylewellman]

So wait a minute.. if fusion reactions require heat, pressure, and time.. does that mean that diamonds are fusion reactions?

[dedeeprice]

Yeah adams bigger than a Mountain

Really doubt that you know tommy structures are
Very small



Yes I learned a lot about nuclear engineering in my youth

My father is a p h d ennuclear engineering

He was based at Wright Patterson
