Possibly a small correction, maybe a clarification: When I was a kid I was taught that it was the shock wave that did all the damage, but I was actually reading about supernovae just recently [1] and found much of what is said in this video about the neutrino apocalypse. However, it doesnt appear to be the case that the shock wave wouldnt get us first, its that the shockwave is neutralised in milliseconds through photodisintegration (Essentially cramming energy back in so that it shifts nuclear fusion in to reverse and robs energy from the collapse.) and the tremendous losses in neutrinos. but it doesnt just stop there. A core maybe 60km across remains, and its life hangs in the balance as it continues to accrete material at a rate of one solar mass every few seconds. Thats enough to turn it in to a black hole in moments if it wasnt emitting a 'prodigious luminosity of neutrinos'. If its ouput is sufficient it will radiate 10% of its mass. (Estimated at a staggering 3x10^53 ergs.*) If its lucky to survive it will leave a remnant just 20km or so across, the most fascinating objects in the universe. A neutron star. (Come at me black hole enthusiasts.) So similar description of events, but I think even more dramatic as the core is in an incomprehensibly momentous tug of war between the tremendous mass and energy falling down upon it and the brain breaking numbers of neutrinos fleeing away. *Kyles figure is actually a couple of orders of magnitude below that. The paper goes in to the details and provides sources for why the observed kinetic energy release is different to the total energy release, but its related to knock on reactions, 'complicated fluid mechanics' and overcoming 'ram pressure' of accreting material.

Hey Kyle, fun episode. Also as someone with thin hair really jealous of those luscious golden locks. Speaking of exploding suns. In season four, episode twenty-two "Exodus" of Stargate SG-1 they exploed a star to destroy an enemy armada. In the episode the team dials the stargate to connect to another stargate that is in the process of being devoured by a blackhole. They then send the stargate into the nearby sun. After being pulled in by the star's gravity where the blackhole's gravitational pull draws some of the sun's mass through the stargate. They say it in effect destablizes the balance of nuclear forces pushing outward and the star's mass gravity pulling inward. Because of them removing a portion of the star's mass so quickly the nuclear forces outward push is able to overcome the gravitational pull in since the star has just become lighter thus lessening its gravity. This causes the star to go supernova destroying the star system. Now would this approach of removing a star's mass so quickly really cause a star to destablize and go supernova? Or would it do something else? Also how much of a star's mass would you have to remove for star to do this? Thanks for the great work. So keep on keeping on. P.S Totally not asking as an aspiring super-villian wishing to tickle the mind of another super-villian.

If you wish to expose every star in the milky way to a dose of supernova radiation every 1000 years on average, then a typical dose rather less than 10^-12 W.

Hey Kyle, Love the show. (Or do I?) So I showed this video to my 2 astronomy professors and asked them what they thought about it. A couple things came up that I'd like to ask directly to you: 1) What exactly about the neutrinos give them the higher energy you mentioned? Because my professors noted that neutrinos are already relativistic particles and they aren't sure where that 25x extra energy would be coming from if not from the kinetic energy (which would be difficult to increase given that they're usually already traveling almost the speed of light). 2) What about the neutrinos larger impact size that you mentioned makes them bigger? I understand that at high energies, the wave uncertainty of particles can increase. (Like how quantum tunneling allows for protons to fuse in our sun's core even though classical mechanics doesn't allow that until it reaches ludicrous temperatures.) But as I already mentioned that neutrinos are already relativistic, how do they gain even more energy? Or is there a different mechanism that I have missed or don't understand properly? Thanks P.S. I do love the show

[@WolfRamAndHart]

Thanks Kyle. Your colorful math gives better visual context, to what I think most people know about supernovae, but seems so distant, with so few in recent memory from even neighboring galaxies. A few notes of interest. One is that the neutrino detectors, based on the math you specified, are really useful at knowing when a supernova has occurred somewhere, in some faraway galaxy, like the 1987 supernovae. It was clearly preceded by an extraordinary number of interacting neutrinos. Two, is perhaps expanding into another episode how this plays out with Betelgeuse...everyone's favorite red star from antiquity. I'd like to hear your thoughts on an about 600 LY away star, that has an equal chance perhaps of having already exploded, to doing so in 100,000 years. Other than a light show, how should this affect mankind? (Including perhaps reference to the star that exploded that caused the Crab Nebula) Three, is a personal theory on neutrinos, and why they're so abundant. Imagine all these ghost neutrinos, having existed wherever and whenever there's been an ultra-rate supernova, but ghosting the rest of the mostly empty universe, perhaps forever, unless it hits a lightyear long block of iron. So neutrinos can be travelling for billions of years, without hitting anything! (or degrading apparently) So of course, they're everywhere! That's kind of fascinating.

Hi Kyle, love the show (gotta get on your good side somehow :P) Why did you not use osmium or tungsten for the calculation? Osmium is almost double as dense as lead is.

Hey Kyle love the show, now that that’s out of the way could we get an episode where you talk about and or debunk the void. Like why it be so big and if the sun went supernova would you even be affected. And how many people can be in the void. Thanks kyle!

[@halcyons88]

Hey Kyle, would neutrinos interact with neutron stars on a much more frequent basis due to the higher density of neutronium? How would this affect neutron stars?

[@DragcoDavid]

Considering Neutron stars are crazy dense and are basically giant atom cores... yeah, they should interact with neutrinos a lot more. But they are also quite small, so that much reduced volume would limit interactions somewhat... plus they are already so energetic, it's hard to tell.

[@isamohammed1107]

Shay 88 You have to also consider the pure density of a nuetron star it self. Though nutrinos are very small in mass, the highly compacted matter of the star wouldn’t probably even let the neutrinos even interact with the matter under the star’s first layer.

[@halcyons88]

@@DragcoDavid thank you Ryuu! I'm gonna try to do the novae equation he made with most of the same information to see what kind of power would be put into the a neutron star at the same radius as earth to the sun but only with normal (non novae ) output.

No. If theoretically our star went Supernova the planets not destroyed by the event would get launched into space because the star's gravity is no longer holding them in orbit. The key to our solar system is Sol.

[@twobearshighfiving7660]

@@blank6604 the chances would be astronomical, but if the bacteria could somehow survive a ride through space, most likely frozen in a peice of ice (unlikely, but possible) and then somehow get caught into the gravity of some Earth like "Goldy-locks zone" planet. (Very unlikely but possible) and then be able to survive the descent onto the planet without burning up, requiring it to be frozen in a very large rock of ice. (Even more unlikely, but possible.) And then beable to adapt to the specific landing environment of this new planet ((see above parenthesis)) than sure, an earthling bacteria could spawn life onto another planet. Many theories exist about that being how life started here but the primordial universe was also a much different place with elements of all kinds flying around, clumping and crashing together. So the chances were much more likely back then.

[@Tzimisce]

@@moukidelmar Not necessarily, depending on the original mass of the star. Remember that stars that go supernova frequently collapse into neutron stars or black holes due to their remaining mass. This may be enough to keep the outer planets gravitationally bound to it.

Hi Kyle, first time commenting your videos. A while ago you made a video about the chances of having life exist somewhere else on the universe, and then diminished that chance by the odds of it achieving technology advanced enough to find us. Seeing this video made me wonder, even if life existed somewhere else, what are the odds that it has already been consumed by a supernova near them?

[@wailazzam834]

Hey Kyle Really loved the Show,Fantastic topic there but only one question:- Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. The question is when the star collapses upon itself and become a black hole wouldn't it prevent the energy and all the light from escaping away from the center of a star. keep making space topic

[@sebastienpaquin4586]

Hi Kyle, love the show! But as an amateur astrophysicist, if there can be such a thing (I don't have a PHD but I do a lot of astrophysics for fun and to entertain friends), I'd like to point to some correction or clarification; - ''We've observed a few of these over the centuries'' It would be important to specify ''with the naked eye'', because we can observe them every day with our telescope, they're even one of the main signpost events we use to measure distances in the universe. - ''Our sun just isn't heavy enough'' Technically, the correct word here is massive. Kyle, you should know the difference between weight and mass! - ''The fusion of iron doesn't yield any additional energy'' Its even worse than that, fusing iron sucks energy out of the star, *takes evil sounding voice* precipitating it inevitable demise even faster! - ''Indescribably small'' while pointing at a description of how small it is. :P - ''How far will a neutrino travel in lead before interacting with a particle of that lead'' *Important to specify on average, otherwise we'd never be able to detect them, and they don't all travel freely then interact after 1.5 ly of lead. Also fun fact, 1.5ly of lead might not even be enough to save you from the neutrino blast! - ''Traveling at more or less the speed of light'' It's definitively less. - ''This neutrino flux would go on to vaporize everything on the planet'' Would it though? It would greatly depend on how long the neutrino flux last at the intensity you calculated, considering it takes around 2,5 million joules to vaporize 1 liter of water, averaging out a human body as a spherical 70kg blob of water, you would need around 1.75 gigajoules to completely vaporize a human body (or we could use the more precise 3 gigajoules that some non-supervillain people who shall remain nameless for personal safety reasons have calculated in the pass). Meaning at a 50,000w intensity, you'd need between an 60 and 100 minutes to vaporize a human body. From observation, we can see neutrino production start to ramp up when the core begins to burn silicon, but only really start to spike in power and intensity when the silicon shell starts to form, which is around... *looks on google* 2 full hour before core collapse? Holy crap, then it is entirely possible that it can vaporize everything, good work Kyle! Though if we take into account the sun's mass which is nearly 10 times less than the smallest supernova we've observed, it's neutrino might be less energetic or the flux might last for a smaller amount of time. Anyway, great episode as always, keep up the good work!

[@texus7079]

Kyle, I recommend reading John Ringo's into the looking glass series, his physicist and co-writer was Travis Taylor and they discuss neutrinos and neutrino capture a lot plus it's a fun read, the book and series also delves into quarks muons and other exotic particles...

[@stevenlouton6381]

Thanks for another awesome episode Kyle, love the show. So question, I know if the sun exploded there would be no shock wave, right? Because there’s nothing to be pushed in space, is my best guess. If that’s so, when all the matter that possible could hit our atmosphere did, would the pressure of the particles moving as fast as they are in the number that they are cause a shockwaves in our atmosphere that could do damage?

Hello Kyle As someone who's fascinated with astronomy, I really like this episode. Thanks giving perspective of what a bunch of Neutrinos can do to our planet. I know you tried to keep it simple, but I'd like to add more. A low-mass star like our Sun can only fuse elements up to Carbon. For a star to go supernova, it must have more than 8 solar masses so then it can have the temperature to fuse elements up to Iron. Another thing is that the core collapse happens so fast that the outer layers wouldn't be able to reach the core before it goes kaboom.

Hi Kyle, love the show. I could missed it, but why are Neutrinos larger? I understand that there are more of them, but I don't get why they are so much larger to have that higher impact area. Also random idea: Can you have black hole somewhere between you and sun to shield you? I guess that it can stop Neutrinos directly towards you, but still it would bend trajectory of others to you as lens.
