- What created the strongest materials in the universe? What is it like inside of a white dwarf or neutron star?
Matt Caplan is a professor of physics at Illinois State University. He received his bachelors from the University of Virginia and PhD from Indiana University- his thesis work was recognized with the 2018 Dissertation Award in Nuclear Physics from the American Physical Society.
Dr. Caplan’s research is broadly concerned with materials at high densities inside stellar remnants, such as crystals that form in white dwarfs and nuclear pasta phases in neutron stars. In addition, he works on nuclear weapons issues and was an inaugural fellow of the Physicists Coalition for Nuclear Threat Reduction. Beyond academia, he is a writer for several TH-cam channels including Kurzgesagt ‘In a Nutshell’ and PBS Spacetime.

Guest: "do you know what the word degeneracy means"
Me whilst erasing my browser history: "N-no?"
Yes. The squids doing dank nooners on their liter bikes through the clibbins.
Lol - funny enough for me

Your feelings betray you young Jedi. 😔
Matt Caplan was a fantastic guest and these questions were perfect for his expertise.
It's always so fun to hear guests light up when you ask them very specific questions that are within their expertise. They get so excited to be able to discuss things on a lower level than they may get to with other podcasters and interviewers.
Fantastic interview, John! Thanks a bunch!!! 😃
Stay safe there with your family! 🖖😊
Well, I know what I will be falling asleep to tonight! Thanks for all the amazing content!

“In the cosmic ballet of the universe, the neutron star performs a pirouette, its surface fiercely alight with the face of a goblin-a creature as mythical as it is mysterious, staring back through the abyss with eyes that twinkle like the very stars themselves.”
This is the kind of comment we love.
@@EventHorizonShowExactly. We don't know what it means, but we love it!
@@AndrewBlucher have another look at the star in the timestamp
@@AndrewBlucherTheres a familiar ferengi face in the star
Thanks John. Great episode as always. Glad you've got long style content like this for when I'm stuck in hospital for a few days. Thanks for keeping me entertained all these years!
john and matt are like kids in a candy store... so excited, just cracking up and what-iffing to beat the band... so much fun in their back and forth...
Im liking this notion of tossing Podcasters onto Stars…
I’d pay a dollar to see that…
Neil deGrasse Tyson is gonna have to change the format of Startalk
What about tossing tiktokers beforehand ?
Writing for Kurzgesacht and PBS Spacetime is impressive on it's own
Thanks for the content cheers from Toronto
Thanks for watching!
I'm sorry but you are mistaken in this video. The strongest material in the universe is the plastic packaging that is used in stores to hold small electronic devices. I can't prove it, but I suspect that they could survive a supernova.
Thank you John for enabling us to access this information from the greatest guests.
I love that you just jumped into the technical talk right away with this podcast.
so far so good so refreshing to have a podcast worth spending my precious minutes on...I'll try one more....
🤌 I'll have my Nuclear Pasta Al-Dente like my Nonna used to make. 🇮🇹 Grazie
This has to be one of my favorite episodes
Awesome video. This is some of the most interesting stuff that our sciences are teaching us about the way our universe works. Just amazing
Glad you enjoyed it!
Quark star, very funny John!
The great Eryn Knight.
Rules of Acquisition 78: never let them use your name for profit...unless it's you using your name.
I'm always amazed by gravity, I constantly learn about how weak gravity is and then discover gravity crushes suns into black holes. Awesome.
It's about space-time.

What a fantastic guest and interview. Thanks for the outstanding content.
Glad you enjoyed it!
I love how the guests always thank JMG for asking great questions. Thanks for another great episode!
Brilliant, love your channel and your obvious excitement for the matters explored! Thank you
I had thought about that. Neutrons that had overcome the strong force keeping them separated, and basically turns the star into a giant solid atom. Man! These kind of topics are incredibly cool.😊 Thank you kind sir.
Very informative, and John, the homework you did really shines through !
Dear Futurist & Author John Michael Goddier,
Make a video on your other channel about how we might apply this to material science in the future.
Make it so.
John is pushing he new fast food chain Neutron Pasta a lot:)
Was saving this one ... by the looks of the comments this is going to be a treat 🎉
Omg yes! been waiting for this one!
I wish you had talked about the source of the magnetic field in a neutron star. I was tought that electrical currents produce a magnetic field, but there are few if any electrons in a neutron star.
What a great interview this guy needs to come on more often 👍
Completely agree!
Excellent presentation. So, can a asymmetrical placement of nucleus of the atom to its electron shell, cause the corkscrew or wave behavior of matter in its unbalanced spin?
Greetings from the BIG SKY. You guys have a good subject that many should know.
Thank you for making this
You can't take material from a degenerative star like a white dwarf or a neutron star. It would immediately explode like a hydrogen bomb. When you remove the gravitational force holding it degenerative, it would immediately resume a normal matter state (perhaps mostly neutrons but even some of these would transform into protons, electrons and anti-neutrinos ie. explosion).
They talked about this in the interview.
This was so enjoyable
@15:28 - Quark star - briulliant 👍👍
This episode utterly failed to put me to sleep ! So interesting!
18:39 Possible islands. Plank scale also time distortion factors. Virtual infinity from the time distortion factor being able to grow. The universe one of the limits. Quark packing along with gluons and neutrinos and photons.
Anything on fluidic neutrinos in neutron stars? Or double Shockwave super nova? Or in tidal events around black holes. Or preferred quantum state and particle generation?
Loved the video and topic. Thank you for sharing. Keep up the good work.
33:55 size and hawking radiation and lifetime. I.E. that size it would glow red hot and get hotter as it evaporates. Or that's my take.
Waiting for tech to enable the finding of black dwarf stars and make Penrose smile.
A scientific definition in 2024 "Nuclear Pasta Layer with a Nuclear Crust". Now I'm getting Hungry....
I’ve been asking for a video on the applications of cold black dwarf matter for years!
❤, it was a great interview with well explained theorys.
That was a great interview!
You guys were talking about finding primordial black hole impacts on the Moon. But if PBHs are impacting the Moon, it stands to reason they're also impacting the Earth. So wouldn't we be finding strange columns of shocked rock in the Earth as well?
Great
Is there a Deep Space Nine alien head sitting in one of the Neutron Stars at the 15 min mark? LOL
And the security chief of that same station is probably close by...in the form of a opossum....
@@edwardbell4928 watching it a little late when was saying to myself is that a ferengi and then I realized yeah it is, it's Quark.
Nice Quark star
Whoa.....a crystalline core! White dwarves are amazing.....Chandrasekharadelic baby!
@EventHorizonShow hey did I overhear it or did you miss the golden chance to ask what it would be like if a primordial black hole that's zipping somewhere in our solar system (meaning also outer layers) hits some matter like a bunch of space rock.
As was stated, a black hole with an accretion disk is the brightest thing in the universe.
You know like... Hey why do we see these bright objects in old photographic plates that are gone in the next plate and are not moving.
You have to just love how contradicting these scientists are, on one hand if you removed nuclear pasta from a nuetron star it reverts to the matter we know but yet you can have a black hole below the minimum mass limit even though not one has been ever detected.
Uh… where’s the contradiction?
@@oberonpanopticon i spelled it out, reread the comment i posted, if you still can not see it then that is on you.
Excellent episode! Nuclear Pasta...band name!
Not even an hour breakdown of how the best material in the multiverse is the old Nokia phone
If there is quark matter, would there be several versions of it that use heavier and heavier quark combinations?
Loved the intro animation ❤
Great video and information !
I wonder if at any point the ability for electrons to act like spin 1 Bosons in superconductors is relevant to how star corpses collapse. I only learned that was part of how superconductors work a couple days ago and it is mind-blowing to me.
Great interview!
Chuck Norris's muscle fibers
Also his beard hair.
dis here one is eminently re-listenable!
Is there a measured ratio of heavy elements as a result of neutron star collisions? EA: average 5% uranium vs 3% gold and so on? I would expect it to either be very consistent (statistically) or very random (chaos theory) due to the nature of the neutron soup being a basic building block for all matter.
15:40 I was looking at it and I was like hey is that a ferengi? Then I realized oh it's Quark, got it. So that might possibly be the nerdiest visual pun I've ever seen. Well played
nice one!
Thank you! Cheers!
Do all degenerate stars have the same charge?
What if I could draw off all the electrons with a black hole? Would You get a proton star or would it explode without enough electrons?
It couldn’t happen right?
I still don’t know why thermal neutrons have different decay rates.
Would one these stars be able to harvested for its elects after it loses it heat ?
Really enjoyed it 😊
A DCC (Degenerate Crystalline Core") 'might' just explain some of the features of Stellar Core Remnants. the oscillations, spin and emissions (for pulsars): are all things that crystals do well.
My bet is that the Chand. Limit is not a 'hard limit', owing to the exotic nature of the unverse and what can occur in it. The notions of Iron being the key 'poison' to determine how the star's fate plays out doesn't necessarily add up. Too many unknowns.
We see how Lanthanides isotopes are happy to form BECs at supercooled temps. Yet, our research into high-energy physics doesn't have great understanding of Lanthanides/Actinides. At least under collider conditions, or atmos pressures we see short half-lives; but we have a poor understanding of what causes Radioactive Decay: and thus under the extreme environment (inside of a star, let alone stellar remnant) it would be wrong to 'assume' that Iron acts as seen here on Earth.
There is argument itself that there really shouldn't be elements higher than Lithium or Carbon in stars. When you're talking temps so high that its 1000s to millions of times temp/pressure needed to melt transition/actinides/lanthanides, there aren't great solutions to HOW the elements don't undergo spontaneous fission...and yet we do detect 'superheavy' elements in stars, indicating fusion> fission.
Basically, there would need to be phases beyond plasma (or perhaps plasma is a 'composite' of several phases, poorly understood) that would explain this.
Granted we have only iota understanding of gravity; but even so, the fact we see that stars have either runaway fission OR fusion reactions ultimately; hints that there is another unobserved force at play inside stars, that doesn't occur outside the high temp/pressures (sustained) inside it.
Depending on what exactly time is mediated by (GR seems bad solution), it could also only arise inside the exotic location (the 'gravity well' that is compressed spacetime which a star resides in. Based on how we see even quantum effects break down on the very upper and lower bounds (IE high-energy, and BEC experiments, universe right after BB), it wouldn't seem too fringe to argue that phenomenon or even additional forces only exist in such locations...ones that are more complex that degeneracy.
Strongest materials I get to deal with are Titanium, Cobalt, and iridium. They happen to be much colder and less radioactive than what we’re talking about here.
God I love science…
Do these hyper dense atoms have fissuon?
Fucking love this channel
'Strongest' vs 'strongest in all conditions'
God I love this channel!
JMG… MASSIVE LEGEND. HONORABLE SCHOLAR.
Nuclear Pasta Phase is my new favorite band name.
Oooooh pasta phases, how delicious!
in the pc game elite dangerous, I jumped into a system with a certain type of neutron star, and it had 2 laser beams spinning around and out of it and the beam hit my ship and almost destroyed it
What is "thleek hith thi theketh ih thi hethleethik"?
Throw another podcaster on the neutron star!
Y’all don’t forget to hit like on this, yeah? Help Event Horizon and JMG!
I’m doing my part! 👍
I think you surprised Matt Caplan with your level of knowledge.
These materials are so strong, even a stubborn jar of pickles wouldn't stand a chance!
Matt has an obsession of throwing podcasters into stars.
incredible, i fell asleep within moments
15:24....Romulan star...??
Ferengi, that character's name is Quark
Doesnt matter how stong it is if you cant use it .
At what point in the video do they actually start discussing the strongest materials in the universe?
What if all solar systems actually condense from premordial black holes
Is there a problem with this show's RSS feed? Last episode I see on there is from 25 days ago, with Garry Nolan and Peter Skafish
So we know about nuclear pasta but we don't know why there's a severe lack of antipasta in the universe.
Lumps of Neutron star explode..Damn Niven's "There is a Tide" can't happen
Sacraficing a podcaster to create a neutron star is now canon.
What is the "shtrong force"?
it's shtronger than the whheak force and a lot shtronger than grabbity
7:43 ummm, what?
Our whole universe was in a hot dense state...
PBH transiting through the Earth...that explains the little holes in my yard...
I see Devil at 15:43
3:10, what the hell is this? A graph, no reference between tha X axis vs what Y axis even is. Why show a graph....if you wont include WTF it means? No frame of reference.....
Wavefunctions
🔥According to the holy books🔥
There are 7 earths😒
Wait. You mean, "transient lunar phenomena", or at least some of them, might be actual black hole "impacts"..?
Also, I'm hungry. For whatever reason...
