Ever since you mentioned Przybylski star on your JMG channel I’ve obsessed over finding more information about it, and I couldn’t find anything that was recently published. Glad that it finally getting a deep dive interview on EH! Godtier!
Wow! The two most soothing sleepy voices on RUclips come together! I am definitely watching this episode at least 30 times till i reach the end after that much good night sleep! Thanks John and David for offering us the resting sleep we need on difficult and hard days of work.
Man when my favorite RUclips creators collaborate like David kipping & J.M.G. I'm in heaven, straight gold, I love it.!. Lmao & I haven't even started the episode yet, I'm just that excited.
I know.!. I'm mad excited, about to dive into it right now, & Honestly good sir, I'd just like thank you for your content, it truly brings joy to my day getting to listen to you.
So delighted to hear Dr. Kipping on Event Horizon with John Micheal Godier! I was hooked every second of it and can't wait to hear more on his developments on exo-moon formations throughout the universe!
I talked with a Physicist about this star and he just said: I am sure a lot of people look into this! But apparently not a lot of people actually do. If the measurements are correct however, this might be one of the best chances to look at the island of stability and other weird phenomena in heavy elements. I have no academic background in astronomy but I strongly assume something wrong with the measurements itself but if the measurements are correct I´d assume something like a micro black hole or a neutron-star like object to be inside it potentially it just got caught or something. But nevertheless it´s one of the most interesting objects I came across so far. The channel might really have an impact on the scientific work on this anomally.
Heh.. I fired this up in hopes of inviting some sleep into my life, but I have to say.. I am wide awake hanging on to every word.. Going to save the rest of this cast for tomorrow. Congratulations, Dr. Kipping on snagging JWST! And thank you, Mr. Godier for what you do.. Good night, folks!
Artificial radiation signatures emitting from a natural structure?!? Sounds like an alien techno signature to me. 370 light years away though, that's far.
Mr Kipping has been pretty busy in the podcast circuit but this is by far the best I've heard. Nice work JMG, your astronomical knowledge and level of pre-podcast research is always first class and this episode is a shining example....Pun intended 😎
Cool Event Horizon Worlds , the best possible combination❣💯👌Thank you very much gentlemen.... Together with Anton Petrov you are my favourite RUclipsrs to watch and listen.
Thank you for researching this Star!!! I am so fascinated by it ( for obvious reasons) and was so happy to see others interested and working on it!!! Beautiful!!!😇❣️✨
JMG. I freakin love you, dude. Everything you say melts my heart. You make such a noticeable effort to remain agnostic on literally every front. I really appreciate the way your brain works. Keep up the great work.
Good God, I'm such an idiot; I started listening and was like: "hmm, that voice is familiar"... until John mentioned the Cool Worlds channel (which is phenomenal) my dumb brain made the connection.
O@@EventHorizonShow be a fan of both of you and many other creative artists, scientists, doctors, rebuilders of engines, and structures. RUclips has a lot to offer the mind.
I really like Dr. Kipping's work in general, and I have studied the skeptical movement's approach for years regarding all astronomy-related anomalous phenomena, and I'm honestly a bit confused with how unsolvable most such scientists find the scientific methodology of (intelligent) "alien hunting". Maybe it's just the fact that natural scientists like astronomers have little to no experience with the study of intelligent beings. Personally, I have a social science and journalism background, and there's plenty of tools for investigating an adversarial intelligence. Including one with superior capabilities. Tools which I'm very sure (based on scores of declassified documents) most military intelligence agencies have been using for decades. Put simply, you need to use approaches and concepts from fields like game theory. Addressing Dr. Kipping's three problems specifically: 1. Everything could be explained by aliens - In abstract maybe, but in practice, all events can't be explained by the same kind of aliens, with the same mentality or intention. You can start from what the aliens *if they were here* clearly aren't doing, and form testable hypotheses of what a compatible, narrowed-down kind of alien intelligence might want to be actively doing. For example to ensure that certain outcomes that aren't happening continue to not be happening - if they're not nuking us, they might not want us to nuke ourselves either. Trying (or pretending) to do something they probably wouldn't want us to do and seeing if it's attracting attention of anomalies or keeps getting mysteriously stopped is one kind of experiment that can be run. 2. Aliens could choose to evade any or all investigations - Again, theoretically maybe, practically probably not. It's reasonable to assume that even advanced stealth or interference technologies employed by a finite alien presence can be at least overwhelmed. An escalating series of probing efforts or provocations, coupled with misdirection and compartmentalization and encryption of research protocols, might be necessary to accomplish that, but it can definitely be attempted. Any negative result would at least help specify how much simultaneous or hidden probing of what types the alien stealth tech can probably still handle, allowing for theoretical progress of such research. 3. We don't have full understanding of what breaks the rules of nature - That's true, but completely irrelevant. The only reasonable scientific procedure is to attack all anomalies (currently inexplicable phenomena). Most of those turning out to be natural isn't a problem. The problem is the either-or logic of naturalists coupled with some sort of irrational (but rationalized) alien giggle factor or taboo. If an anomaly is probably natural, but could still be some kind of aliens, that's what the scientific fact is. With the emphasis on "some kind". The progress in alien hunting is narrowing what kind of aliens an anomaly still could be, given the best current data, which is a fact that can inform better tests to narrow down the classification further. In social sciences, the fact that the answer is probabilistic doesn't make it unscientific. That's just accurate communication of scientific results.
I think Kipping's approach of 'forced agnosticism' is the correct one. I'm glad he touched on scientific epistemology. I don't think that is considered nearly enough in our public debates.
Omg DAVID KIPPING!! This is sooooooo awesome having him on here!! This is soooooo cool!! Also this star does indeed look as though it is a technosignature

How exciting! I hadn't heard Dr Kipping and team finally got accepted to use JWST! Congrats! As always, hearing both of you discuss these things is always such a treat. :)
Issac Arthur is the man! I don't know who's episode will be better with j.m.g. Arthur or kipping, I haven't watched this episode yet but I'm about to find out.
The low absorption of green light (500-600 nm) is due to the plants optimizing for both blue (400-500 nm) and red light (600-700 nm). Peak absorption of light is a curve within the blue and red spectrum making the low point of the absorption curve green.
back when we didnt have high powered leds and lithium batteries i used to make bike lights with extended runtimes. part of that was using an aqua green light. your eyes adjust to it after about 15mins and it becomes brighter than you would get a white light to shine. i loved going through the forests full of blue trees and plants. they all turn a dark blueish green in that light. its really pretty.
Dear Mr. Godier,I hope this message finds you well. My name is James Murphy, and I'm a regular listener of your "Event Horizon" podcast. I've always found the topics you cover both enlightening and engaging, which speaks volumes about the effort you put into your work.I'm reaching out to inquire about the background music used in your episodes. There's a particular piece that resonates with me, and I was hoping to learn more about it-its title, the artist, or where I might find it. Your selection enhances the ambiance of the discussions, and this piece, in particular, has caught my attention.I understand you're quite busy, and I appreciate any information you can provide, whenever it's convenient for you.Thank you for your time and for the incredible content you create. It's greatly appreciated by myself and many others.Warm regards, James Murphy
The "fine tuning" hypothesis is the best example of observational bias there is. By that thinking, the arctic is amazingly tuned to the polar bear and my local reservoir is somehow tuned to the smallmouth bass that live in it.
Luvv to hear details of planets and moons ...including mining interests and how makeup creates space bodies relationships, interactions and paths in space.
Another fantastic interview, John! 😃 Dr. Kipping is great! About that star, if that's a technosignal, I know exactly what it means: stay away! 😬 Anyway, stay safe there with your family! 🖖😊
Actually, it is the hugest display window they could make. It says, Cheapest high quality Plutonium in galaxy! Do not seek any further, fly right to us!
This guy is great, at the end of the interview, he makes the argument that we shouldn’t investigate the unknown because we don’t know what we don’t know.
Ooo oo I know an answer to this one! I read a cool paper once postulating that plants don't absorb green light because the intensity of green light varies throughout the day with solar intensity, causing spikes of energy that are too much for the plants to absorb and troughs where there's not enough green light to absorb. Instead, plants target blue and red light, the intensity of which --- when added together -- stays remarkably constant throughout the day (red light in the early/late day and blue light predominating in the middle). This gives the plant a very stable energy source. This might be more valuable than fully taking advantage of the peak intensities of your star.
I'm flying to Sulfur Springs, Texas, for the April eclipse this week! Near four and a half minutes of totality! This is going to be fabulous! I am incredibly excited about this! Obviously.🤯😛😜🤪😝
Super interesting stuff with super intelligent hosts Trouble is John Michael voice is like Vicodin and David Kipping voice is like Xanax Im never gonna make it to the end without falling asleep
Really loved this podcast. Not sure how I feel about that last bit though. I really like and admire David's usual stance about being agnostic. It feels really really presumptuous to declare that the universe is likely devoid of intelligent life because it seems like it isn't full of it. It's a very extreme and large conclusion to arrive at based on something completely un-empirical (The thought experiment about chemistry). Because as David says just before that, once you develop a prior you also develop confirmation bias for that prior.
On Przyblyski's Star: The jury is out until some southern hemisphere observatory takes recent spectra to confirm or deny the weird elements. "One tenth the mass of Vesta..." of rare elements would need to be dumped onto the star every year if ETI is "salting" the star. That works out to be 30 quadrillion tons. Lotsa ore that would need to be either highly refined .....or transmuted. Not feasible for a Type 1 civilization. Maybe for a Type 2, which seems would give other confirming technosignature flags.... but this amount of salting appears to be a lot of wasted energy just to announce "we are here".
So stoked to hear you mention Spinoza’s God, I am a massive proponent of Spinozan Pantheism and respecting the divinity of the universal fundamental. I wish more people felt the sense of reverence and divinity for that which not only lay right in front of us but composes us and is quite literally within and without us. There’s beauty missed with considering this universe cold, dark, and void, whereas you can see it all as the beautiful workings of the Divine Whole!
34:58 at that level of mass, given the implication that a civilization would be dumping that material in, it's plausible or at the very least on the list. Question is... would this be... the most efficient method to signal "we're here" or would this be the most efficient means of disposal or does this serve a purpose we've yet to understand about stellar mechanics? Dunno about other people, but when you consider the "cost" and rate it over purpose, without getting into the "absurd" (read absolutes and beyond) ... it doesn't seem like something a civilization would be doing. They're not modulating it, just pumping it through, if it's a message. That leaves to be desired, as messages go, because it could be natural or someone would assume it's natural in the absence of that modulation. What's the point of disposing it into the sun? Could just as well use it for something else or just shoot it out of the system. Which leaves a mechanic we yet understand. Well, it could be anything, could be natural - could be something they're doing to alter (somehow - for some purpose) what the star does. Which is a bit beyond my pay grade. So IMO, plausible, but only by skin of it. A hair away from being nothing at all and just a peculiarity we don't comprehend. Be it at the user end or at that end.
Or are we being way to narcissistic here in assuming this is an attempt to signal us? Maybe this is merely what Kardashev 2 industry looks like when a civ gets around to star lifting and nucleosynthesis?😊
To me, it seems most likely that it's simply a natural process that we either lack the instrument fidelity to properly observe and identify or one that we are just unfamiliar with. In the 19th century, astronomers believed the Sun was emitting a new element, which was named "coronium" -- but it was later found that it was simply iron that was very heavily ionized. This was also the case with "nebulium," a "new" element that was found in spectroscopic observations of the Cat's Eye nebula in the late 19th century -- that turned out to just be ionized oxygen. It's very possible that what we see in Przbylski's star are simply very normal elements that are in an environment or ionized state that we are unfamiliar with.
Just going with the alien hypothesis for a moment, as I listened I was thinking that plutonium is not nuclear waste, why not use it for power generation? Perhaps an advanced civilization has fusion and doesn't need that stuff anymore. They decide it is dangerous to keep around and dispose of it in their star so no one can retrieve it. But it will probably turn out to be some rare natural explanation.
It’s shocking that the mother of all anomalous astronomical objects in Prybylski’s star is mostly unheard of and completely ignored by professional astronomers. Leaving aside the alien hypothesis, Prybylski’s star converges many scientific disciplines and nearly breaks many well establish models across those disciplines. That alone is a reason why Prybylski’s star should be thoroughly researched by top scientists in Astronomy, Physics, Chemistry and more. Q: What more could be learned about Prybylski’s star via JWST or the future Vera Rubin or Nancy Roman Grace telescopes?
It's drawn a number of observation studies, but there's only so much we can learn with our current technology. JWST probably wouldn't be able to provide any better information than ground-based observations either -- it's designed for infrared observations of the farthest reaches of the observable universe, and stellar spectroscopy of what is essentially a neighbor in comparison works just as well from an Earth observatory as it does in a space-based telescope.
Sadly, it seems that there are a lot of academics that will not look in the obvious place for possible techno signatures. (See the places the Mars rovers are placed, for examples) They don’t want to find it and mock anybody doing real science. This is another reason I enjoy listening to JMG and Professor Kipping among others, they will look at all of it with an open mind while staying grounded.
Plants don't use green light because of a quirk of the energy needed to excite a catalyst to convert ADP into ATP. This reaction costs energy, so ideally the single captured photon should provide all the energy needed plus a bit extra to make the gods of entropy happy.
It may not be what he’d be into personally, but I think David would do well as a like Brian Cox level science communicator. Not that Cool Worlds isn’t a big channel, but giving whole tours etc. he has a calm approach and uses easy to understand yet effective example to explain concepts
As for green stars I recall that there was a story by Poul Anderson with such a sun and it was explained as happening because the emission spectrum of an object narrows as it's temperature increases. This fictional star was leaving the main sequence and heating up so the narrowed part of its spectrum happened to be passing through the green wavelengths. Whether this can work on the scale of a sun in the real world might be questionable.
I've known about the island of stability for years but recently also heard about the potential continent of stability, which would be even more interesting. Wonder what the spectral signature of that stuff would be.
"Intelligence seems rare" on a planet covered by an intelligent species. You can't make the "rare" assertion while 1 out of 8 ( or 9 ) of your known and observable planets has an intelligent species that has sent rockets into space... and by "intelligent" standards, we're barely out of ape territory. The only conclusion you can currently deduce on a universal scale is "undefined" -- there's not enough data to even begin to make an assertion. If you only based your assertion on the known and observable planets, then you'd have to conclude "not rare". Also, your guest didn't prove his assertion that "everything can be explained by asserting aliens did it". Who does that? The only thing that would cause people to conclude "aliens" is an unambiguous non-terrestrial form of technology. Even most of the UAP aficionados aren't in agreement on whether UAP are alien tech or just Pentagon toys. That was like a meta straw man. You assert the base logic of all arguments for all unexplained phenomena would be to assume intelligent alien life. Such an assertion is ludicrous on its face. Most credible thinkers would only conclude "alien" with unambiguous material proof. Why would you assert that nobody would hold to that standard -- as if you could mind-read every future person's argument before they even think it. I shouldn't have to tell either you that such tactics are sophistry. As for me, I won't believe in aliens until I see one in person -- and even then I'll assume I've been drugged and halucinating. When ostensibly intelligent people can't spot basic logical fallacies tumbling out of their mouths I causes me to wonder what our schools have been teaching.
I would note that we have evidence from sediments dated to 2.6 Ma or so that a nearby supernovae event delivered Pu 244 along with other short lived radioisotopes like Fe 60 who is to say the Plutonium didn't arrive to Przybylski’s star there in a similarly exotic event. As for Actinium that could be a decay chain intermediaries but the heavier actinides is yeah if that is real it is interesting. Was it perhaps a nearby a Kilonovae? A billion years does fit the timescale for Neutron star inspiral and this star has some weird properties so might it be possible we just have to be cosmically speaking relatively recent enough for these heavy elements to still be there. What do we know about Przybylski’s star's orbital dynamics? From what I looked at this star is around 1.5 solar masses and we haven't found a companion via radial velocity but that doesn't restrict massive companions if aligned with the plane of the system relative to us. The strong magnetism of Ap stars is interesting and given what we know about other classes of exotic stars stellar mergers could something similar be at play? Perhaps related to the merger scenario if the resulting debris nebulae was sucked in? Is there still nebulosity there now today? We should look for the predicted effects if there is a hidden neutron star companion or the possible black hole from two colliding neutron stars. As for the moon orientation the recent discovery that the tilt of Saturn is still increasing and ongoing tilting of Saturn caused by tidal effects of titan and the ring system receding. That was a surprising but fascinating find which adds to the case that something catastrophic must have happened there around a billion years ago or younger. From the biology perspective as I have been diving into astrobiology there seems to be work studying anaerobic photosynthetic life which has curiously found that the reason could be related to the high electronegativity. In particular aerobic photosynthesis uses water as the source of hydrogen and the needed energy to split those hydrogen atoms away from oxygen corresponds to the blue wavelengths. There was an adaptation involving at least similar types of pigments shared between aerobic photosynthetic life and green sulfur bacteria which at least in aerobic photosynthesis allows 3 red wavelength range photons to be absorbed and reprocessed as a photon of blue wavelength energy. This possibly gives a quantum mechanical limit on why plants might be green at least in part. There are reasons to doubt that is the full picture as those green sulfur bacteria have no such need to use such high energy photons and some understory plants do use green light for photosynthesis showing that it isn't impossible to use it. My suspicion is that the reason will be due to heat as chloroplasts need to be kept within a narrow window of temperatures which plants usually do via evapotranspiration. This coupled with the generally bad outcomes that occur if low light adapted plants are suddenly exposed to full sunlight suggests that it may be a case of too much activity in their photosynthetic reaction centers which would be supported by some plants algae and cyanobacteria in high intensity light conditions adopting red pigments (which people will also sometimes breed into plants too I should note). I suspect it is a combination of both of these effects base don what I have read but more research is needed and there is evidence that at least in the case of oxygenation the standard narrative is wholly insufficient. In the case of Boyajian's star perhaps the long term dimming and the possible collision were related? After all the Ordovician Meteor event was a major collision between two asteroids which created a lot of debris which may be undergoing secondary collisions during the interval of several million years where such collisions are much more likely. Dr. Kipping echoes my thoughts on UAP's from the get go though my immediate though was skeptical from the get go but I tend to be very skeptical most of the time fore this kind of stuff. Keep an open mind and be aware of possibilities but be skeptical especially with god in the gaps mechanisms as gods, aliens or fairies(which seem to have been the predecessor of UFO/alien sightings).
The real issue is the other transuranics above the table from plutonium. Some of them have no stable isotopes, and some have very short half-lives, I think the longest lived isotope of Einsteinium is just over a year. So whatever is going on, it's actively replenishing these elements if the observation and interpretation of the spectra are correct. So if it was a kilonova, we'd know, because it would have had to happen sometime the previous year. We'd see that. Another option is bombardment by a neutron star, but again, it would need to be active or recent, and there is no neutron star there. There are just very few possibilities for it when you account for the very short half-lives of some of these elements. That said, it really needs confirmation to ensure that these elements are really there and being interpreted correctly. That's step one. One other aspect though is that they could be decay products of more stable elements higher up the periodic table in the so called island of stability, if that exists. We've never synthesized any of that stuff, so it remains theoretical, but again it's unclear how this single star could do it, but no other star we know of does. Tabby's star is a different story of course. Yes, I think the case can be made that the long term overall dimming could be due to a dispersion effect after a collision. Consistent with this is the overall decline in the depths of the dips that have been subsequently observed. They aren't the really severe 22 percent dips anymore, more like 1-3 percent, which seems like dispersion. Trouble is, there should be infrared visible, warm dust afterall and observations didn't show that though the JWST observations might whenever they come out. So that led to the cold comets colliding hypotheses Dr. Boyajian initially advanced, but that too has issues in that the profiles do not match exocomets and it would require an implausibly huge amount of cold comets to do it. With UAP, all that's needed is some quality evidence and word of mouth accounts won't hit that bar. I simply leave it at that. I'll take a look at anything, and be open, but so far my bar hasn't been hit by anything.
@@JohnMichaelGodier Yeah if these more exotic transuranic elements exist in its spectrum that would change things though it might work well in the context of the so called island of stability. As for the neutron star from what I looked up in a not very comprehensive search none has been detected but there is still a possibility if it is positioned such that no radial velocity signal would be viewed from Earth that it could still be there, unlikely but not yet ruled out entirely. Wasn't there an object which is based on the idea a neutron star could sink into the interior of a star? I doubt it is the case here but something odd is going on. The other explanation for the long term dimming with Tabby's star I have heard is that there might have been a gaseous planet that crashed into the star some time ago and cause it to brighten with the star slowly relaxing to its normal brightness with the odd dipping possibly being due to now unbound icy moons slowly evaporating away. Probably unlikely but its an odd star.
@@Dragrath1 There is, the neutron star engulfed in a normal star is a Thorne-Zytkow object. There are predictions about what that might do to a star, and there are candidates for it. You should see higher levels of calcium and lithium, but also elevated rubidium and molybdenum. You should also see higher than normal luminosity, which is not seen at Przybylski's star. But there are questions there, what does the spin of the neutron star do to alter the conditions etc. What's interesting about Thorne-Zytkow objects is that there's no reason they shouldn't exist physically. With Tabby's star, the intrinsic to the star explanations have fallen short. There have been several, giant star spots, recently ate a planet etc, but what should be seen in such a case is periodicity as the star rotates and whatever blemish comes into view. You'd also expect the star to act strangely, Kepler could see variability in the stars themselves and much of it was very characteristic, short upticks in luminosity due to flaring etc. and Tabby's star was just behaving like a normal F-type star. The real key is to observe the star again and confirm the presence of those elements, and then look for other examples in type Ap peculiar stars.
The null result, not finding a moon might be more interesting for science, but I don't believe for a second that Dr Kipping is "hoping" for that to be the case. I have followed his channel for quite a while and his dedication and passion for finding an exo-moon only leads me to hope that his name is forever linked to the first confirmed discovery of one. It makes it even more poetic if it is found around a planet he discovered.
Great interview John! I really enjoyed it. It is sad to hear the ignorance of David around UAP. I wish these folk would take the time to review the history before making judgments …this area needs as many scientific minds as we can get to understand this phenomena.
Its kind of a wierd status quo bias. A lot of these guys probably have more interest/belief in the subject that they let on, but to show it means ridicule. And show it to much and you might as well just change fields, because the entire community of science will literally turn its back to them. Its an outdated stigma. Much like the idea "The true knowledge of the government on UAPs would send civilization into a panic and the world would collapse." Dude, you could prove they were real and ate here to feed on us and I guarantee 4/5 people would just turn the channel. 1/3 would believe it was lies even if president introduced them in a state of the union and told us everything. Full disclosure would only confirm what we all already know, and for the rest who are self absorbed? They will be totally unaffected.
We're not 100% sure on a SPECIFIC cause for the dimming, but AFAIK the dimming has by now generally been agreed to seem to be dust-based dimming, like that it has a partial dust-cloud around it that occludes the star to various degrees. The visual signal faded much more than its IR signature, as I recall, and we have other stars with similar 'less visual but not-so-less IR fading' behavior that we're pretty sure on the source of. So we're not SURE on what exactly it is, but I think only the nutjobs are still hoping it's an uneven Dyson sphere. The leading theory is a partial planetary dust cloud or the like. So it's still a bit of a mystery, but only in details, not in "Are there aliens there or not?!" Ah, in fact, right from the Wikipedia page, "The latest results have ruled out explanations involving only opaque objects such as stars, planets, swarms of asteroids, or alien megastructures." The only big confusion about 'planetary dust cloud' would be that the star is a 'normal F-type' of adequate age as to no longer have a proto-planetary disk, so if there is dust, we aren't sure WHY there might be, even though we seem to think it to be the best candidate for 'what could cause the observed dimming'. There is no 'protoplanetary disk', but we think the proto-disk option is the best fit answer for what we observe...confusion! Maybe a planet broke up somehow, who knows. So the mystery of Tabby's Star is much REDUCED, but not totally ended yet.
Regarding the UAP videos and pilots stating they've seen uap whilst flying.. I disagree with Kipping's point that of course things are going to happen sometimes out of thousands and thousands of flight hours and that sometimes pilots are going to get it wrong and think they saw something anomalous when they really didn't, so that it could just be pilot error. That's not taking into account AT ALL that various pilots have said there were times they'd see these same things every single day for weeks or months. That absolutely ISN'T just thinking you saw something anomalous once out of thousands of flight hours.
I think his argument is that during one million flight hours you will definitely find an entire squad of pilots that are all sky high on extasy, mushrooms, marijuana and other illicit substances.

I talked with a Physicist about this star and he just said: I am sure a lot of people look into this! But apparently not a lot of people actually do. If the measurements are correct however, this might be one of the best chances to look at the island of stability and other weird phenomena in heavy elements.
I have no academic background in astronomy but I strongly assume something wrong with the measurements itself but if the measurements are correct I´d assume something like a micro black hole or a neutron-star like object to be inside it potentially it just got caught or something. But nevertheless it´s one of the most interesting objects I came across so far.

Thank you for researching this Star!!! I am so fascinated by it ( for obvious reasons) and was so happy to see others interested and working on it!!! Beautiful!!!😇❣️✨
JMG. I freakin love you, dude. Everything you say melts my heart. You make such a noticeable effort to remain agnostic on literally every front. I really appreciate the way your brain works. Keep up the great work.
Great Episode!
This could only be topped by having JMG, David Kipping and Matt O'Dowd together
I caught my first video last night. Haven’t stopped watching since. Thanks for the unbelievable content.
This content is why I subscribe to this channel. Good stuff!
Good God, I'm such an idiot; I started listening and was like: "hmm, that voice is familiar"... until John mentioned the Cool Worlds channel (which is phenomenal) my dumb brain made the connection.

One of the absolute best channels on RUclips
I really like Dr. Kipping's work in general, and I have studied the skeptical movement's approach for years regarding all astronomy-related anomalous phenomena, and I'm honestly a bit confused with how unsolvable most such scientists find the scientific methodology of (intelligent) "alien hunting".
Maybe it's just the fact that natural scientists like astronomers have little to no experience with the study of intelligent beings. Personally, I have a social science and journalism background, and there's plenty of tools for investigating an adversarial intelligence. Including one with superior capabilities. Tools which I'm very sure (based on scores of declassified documents) most military intelligence agencies have been using for decades.
Put simply, you need to use approaches and concepts from fields like game theory. Addressing Dr. Kipping's three problems specifically:
1. Everything could be explained by aliens
- In abstract maybe, but in practice, all events can't be explained by the same kind of aliens, with the same mentality or intention. You can start from what the aliens *if they were here* clearly aren't doing, and form testable hypotheses of what a compatible, narrowed-down kind of alien intelligence might want to be actively doing. For example to ensure that certain outcomes that aren't happening continue to not be happening - if they're not nuking us, they might not want us to nuke ourselves either. Trying (or pretending) to do something they probably wouldn't want us to do and seeing if it's attracting attention of anomalies or keeps getting mysteriously stopped is one kind of experiment that can be run.
2. Aliens could choose to evade any or all investigations
- Again, theoretically maybe, practically probably not. It's reasonable to assume that even advanced stealth or interference technologies employed by a finite alien presence can be at least overwhelmed. An escalating series of probing efforts or provocations, coupled with misdirection and compartmentalization and encryption of research protocols, might be necessary to accomplish that, but it can definitely be attempted. Any negative result would at least help specify how much simultaneous or hidden probing of what types the alien stealth tech can probably still handle, allowing for theoretical progress of such research.
3. We don't have full understanding of what breaks the rules of nature
- That's true, but completely irrelevant. The only reasonable scientific procedure is to attack all anomalies (currently inexplicable phenomena). Most of those turning out to be natural isn't a problem. The problem is the either-or logic of naturalists coupled with some sort of irrational (but rationalized) alien giggle factor or taboo. If an anomaly is probably natural, but could still be some kind of aliens, that's what the scientific fact is. With the emphasis on "some kind". The progress in alien hunting is narrowing what kind of aliens an anomaly still could be, given the best current data, which is a fact that can inform better tests to narrow down the classification further. In social sciences, the fact that the answer is probabilistic doesn't make it unscientific. That's just accurate communication of scientific results.
I think Kipping's approach of 'forced agnosticism' is the correct one. I'm glad he touched on scientific epistemology. I don't think that is considered nearly enough in our public debates.
Omg DAVID KIPPING!! This is sooooooo awesome having him on here!! This is soooooo cool!!

The low absorption of green light (500-600 nm) is due to the plants optimizing for both blue (400-500 nm) and red light (600-700 nm). Peak absorption of light is a curve within the blue and red spectrum making the low point of the absorption curve green.
back when we didnt have high powered leds and lithium batteries i used to make bike lights with extended runtimes. part of that was using an aqua green light. your eyes adjust to it after about 15mins and it becomes brighter than you would get a white light to shine.
i loved going through the forests full of blue trees and plants.
they all turn a dark blueish green in that light.
its really pretty.
Dear Mr. Godier,I hope this message finds you well. My name is James Murphy, and I'm a regular listener of your "Event Horizon" podcast. I've always found the topics you cover both enlightening and engaging, which speaks volumes about the effort you put into your work.I'm reaching out to inquire about the background music used in your episodes. There's a particular piece that resonates with me, and I was hoping to learn more about it-its title, the artist, or where I might find it. Your selection enhances the ambiance of the discussions, and this piece, in particular, has caught my attention.I understand you're quite busy, and I appreciate any information you can provide, whenever it's convenient for you.Thank you for your time and for the incredible content you create. It's greatly appreciated by myself and many others.Warm regards, James Murphy
Hi James, this is Ross the producer responding. Thank you for the kind words. Do you know what time in the episode the music plays?

@@u.v.s.5583 Makes sense as well... 🤔
This guy is great, at the end of the interview, he makes the argument that we shouldn’t investigate the unknown because we don’t know what we don’t know.
Ooo oo I know an answer to this one! I read a cool paper once postulating that plants don't absorb green light because the intensity of green light varies throughout the day with solar intensity, causing spikes of energy that are too much for the plants to absorb and troughs where there's not enough green light to absorb. Instead, plants target blue and red light, the intensity of which --- when added together -- stays remarkably constant throughout the day (red light in the early/late day and blue light predominating in the middle). This gives the plant a very stable energy source. This might be more valuable than fully taking advantage of the peak intensities of your star.
Thank you kindly for this ya Champion!

I'm a fan in any case, but this episode went over and above. Great conversation.
NO1 guest speaker on this show.
Really loved this podcast. Not sure how I feel about that last bit though. I really like and admire David's usual stance about being agnostic. It feels really really presumptuous to declare that the universe is likely devoid of intelligent life because it seems like it isn't full of it. It's a very extreme and large conclusion to arrive at based on something completely un-empirical (The thought experiment about chemistry). Because as David says just before that, once you develop a prior you also develop confirmation bias for that prior.
Why in the WORLD isnt there more hype and discussion about this star?
Hey thanks, in the 1st 10 minutes you answered my questions about how feasible it is to see what types of exomoons and where. That's great.
On Przyblyski's Star: The jury is out until some southern hemisphere observatory takes recent spectra to confirm or deny the weird elements.
"One tenth the mass of Vesta..." of rare elements would need to be dumped onto the star every year if ETI is "salting" the star. That works out to be 30 quadrillion tons. Lotsa ore that would need to be either highly refined .....or transmuted.
Not feasible for a Type 1 civilization. Maybe for a Type 2, which seems would give other confirming technosignature flags.... but this amount of salting appears to be a lot of wasted energy just to announce "we are here".
So stoked to hear you mention Spinoza’s God, I am a massive proponent of Spinozan Pantheism and respecting the divinity of the universal fundamental. I wish more people felt the sense of reverence and divinity for that which not only lay right in front of us but composes us and is quite literally within and without us. There’s beauty missed with considering this universe cold, dark, and void, whereas you can see it all as the beautiful workings of the Divine Whole!
Omg! I can't wait to watch this after I finish a few things and can try to relax. You're awesome!! 😊🌎❤️🕺🏻🐶🛸
Have fun!
Love Dr Kipping and his Cool Worlds channel (not as much as yours obviously! 😉) this episode is going to be awesome.
34:58 at that level of mass, given the implication that a civilization would be dumping that material in, it's plausible or at the very least on the list. Question is... would this be... the most efficient method to signal "we're here" or would this be the most efficient means of disposal or does this serve a purpose we've yet to understand about stellar mechanics? Dunno about other people, but when you consider the "cost" and rate it over purpose, without getting into the "absurd" (read absolutes and beyond) ... it doesn't seem like something a civilization would be doing.
They're not modulating it, just pumping it through, if it's a message. That leaves to be desired, as messages go, because it could be natural or someone would assume it's natural in the absence of that modulation.
What's the point of disposing it into the sun? Could just as well use it for something else or just shoot it out of the system.
Which leaves a mechanic we yet understand. Well, it could be anything, could be natural - could be something they're doing to alter (somehow - for some purpose) what the star does. Which is a bit beyond my pay grade.
So IMO, plausible, but only by skin of it. A hair away from being nothing at all and just a peculiarity we don't comprehend. Be it at the user end or at that end.
Or are we being way to narcissistic here in assuming this is an attempt to signal us?
Maybe this is merely what Kardashev 2 industry looks like when a civ gets around to star lifting and nucleosynthesis?😊
To me, it seems most likely that it's simply a natural process that we either lack the instrument fidelity to properly observe and identify or one that we are just unfamiliar with. In the 19th century, astronomers believed the Sun was emitting a new element, which was named "coronium" -- but it was later found that it was simply iron that was very heavily ionized. This was also the case with "nebulium," a "new" element that was found in spectroscopic observations of the Cat's Eye nebula in the late 19th century -- that turned out to just be ionized oxygen. It's very possible that what we see in Przbylski's star are simply very normal elements that are in an environment or ionized state that we are unfamiliar with.
Just going with the alien hypothesis for a moment, as I listened I was thinking that plutonium is not nuclear waste, why not use it for power generation? Perhaps an advanced civilization has fusion and doesn't need that stuff anymore. They decide it is dangerous to keep around and dispose of it in their star so no one can retrieve it. But it will probably turn out to be some rare natural explanation.
It’s shocking that the mother of all anomalous astronomical objects in Prybylski’s star is mostly unheard of and completely ignored by professional astronomers.
Leaving aside the alien hypothesis, Prybylski’s star converges many scientific disciplines and nearly breaks many well establish models across those disciplines. That alone is a reason why Prybylski’s star should be thoroughly researched by top scientists in Astronomy, Physics, Chemistry and more.
Q: What more could be learned about Prybylski’s star via JWST or the future Vera Rubin or Nancy Roman Grace telescopes?
It's drawn a number of observation studies, but there's only so much we can learn with our current technology. JWST probably wouldn't be able to provide any better information than ground-based observations either -- it's designed for infrared observations of the farthest reaches of the observable universe, and stellar spectroscopy of what is essentially a neighbor in comparison works just as well from an Earth observatory as it does in a space-based telescope.
Sadly, it seems that there are a lot of academics that will not look in the obvious place for possible techno signatures. (See the places the Mars rovers are placed, for examples)
They don’t want to find it and mock anybody doing real science.
This is another reason I enjoy listening to JMG and Professor Kipping among others, they will look at all of it with an open mind while staying grounded.
I just heard about this star the other day and I can't fathom why more isn't being made of it. This seems absolutely groundbreaking.
Plants don't use green light because of a quirk of the energy needed to excite a catalyst to convert ADP into ATP. This reaction costs energy, so ideally the single captured photon should provide all the energy needed plus a bit extra to make the gods of entropy happy.
It may not be what he’d be into personally, but I think David would do well as a like Brian Cox level science communicator. Not that Cool Worlds isn’t a big channel, but giving whole tours etc. he has a calm approach and uses easy to understand yet effective example to explain concepts
Cool Worlds is a brilliant channel !!
Cool Worlds is a great channel if you don't follow it already.
As for green stars I recall that there was a story by Poul Anderson with such a sun and it was explained as happening because the emission spectrum of an object narrows as it's temperature increases. This fictional star was leaving the main sequence and heating up so the narrowed part of its spectrum happened to be passing through the green wavelengths. Whether this can work on the scale of a sun in the real world might be questionable.
Congratulations David! Such an amazing feat to get 72 hours of JWST. You're going to make history
I've known about the island of stability for years but recently also heard about the potential continent of stability, which would be even more interesting. Wonder what the spectral signature of that stuff would be.
Whenever you see "Przybylski" typed out, I'm always worried someone is having a stroke in front of their computer.
Has SETI taken a look at the Przybylski’s Star or the system it's in?
thanks so much gents… great talk 🤙🏼
Great show John!!
"Intelligence seems rare" on a planet covered by an intelligent species.
You can't make the "rare" assertion while 1 out of 8 ( or 9 ) of your known and observable planets has an intelligent species that has sent rockets into space... and by "intelligent" standards, we're barely out of ape territory. The only conclusion you can currently deduce on a universal scale is "undefined" -- there's not enough data to even begin to make an assertion.
If you only based your assertion on the known and observable planets, then you'd have to conclude "not rare".
Also, your guest didn't prove his assertion that "everything can be explained by asserting aliens did it". Who does that? The only thing that would cause people to conclude "aliens" is an unambiguous non-terrestrial form of technology. Even most of the UAP aficionados aren't in agreement on whether UAP are alien tech or just Pentagon toys.
That was like a meta straw man. You assert the base logic of all arguments for all unexplained phenomena would be to assume intelligent alien life. Such an assertion is ludicrous on its face. Most credible thinkers would only conclude "alien" with unambiguous material proof. Why would you assert that nobody would hold to that standard -- as if you could mind-read every future person's argument before they even think it.
I shouldn't have to tell either you that such tactics are sophistry.
As for me, I won't believe in aliens until I see one in person -- and even then I'll assume I've been drugged and halucinating.
When ostensibly intelligent people can't spot basic logical fallacies tumbling out of their mouths I causes me to wonder what our schools have been teaching.
I see SV’s and citations and hit subscribe. :) Can’t wait for the science-y rabbit hole adventures you’re facilitating for me, here!
I would note that we have evidence from sediments dated to 2.6 Ma or so that a nearby supernovae event delivered Pu 244 along with other short lived radioisotopes like Fe 60 who is to say the Plutonium didn't arrive to Przybylski’s star there in a similarly exotic event. As for Actinium that could be a decay chain intermediaries but the heavier actinides is yeah if that is real it is interesting. Was it perhaps a nearby a Kilonovae? A billion years does fit the timescale for Neutron star inspiral and this star has some weird properties so might it be possible we just have to be cosmically speaking relatively recent enough for these heavy elements to still be there.
What do we know about Przybylski’s star's orbital dynamics? From what I looked at this star is around 1.5 solar masses and we haven't found a companion via radial velocity but that doesn't restrict massive companions if aligned with the plane of the system relative to us. The strong magnetism of Ap stars is interesting and given what we know about other classes of exotic stars stellar mergers could something similar be at play? Perhaps related to the merger scenario if the resulting debris nebulae was sucked in? Is there still nebulosity there now today? We should look for the predicted effects if there is a hidden neutron star companion or the possible black hole from two colliding neutron stars.
As for the moon orientation the recent discovery that the tilt of Saturn is still increasing and ongoing tilting of Saturn caused by tidal effects of titan and the ring system receding. That was a surprising but fascinating find which adds to the case that something catastrophic must have happened there around a billion years ago or younger.
From the biology perspective as I have been diving into astrobiology there seems to be work studying anaerobic photosynthetic life which has curiously found that the reason could be related to the high electronegativity. In particular aerobic photosynthesis uses water as the source of hydrogen and the needed energy to split those hydrogen atoms away from oxygen corresponds to the blue wavelengths. There was an adaptation involving at least similar types of pigments shared between aerobic photosynthetic life and green sulfur bacteria which at least in aerobic photosynthesis allows 3 red wavelength range photons to be absorbed and reprocessed as a photon of blue wavelength energy. This possibly gives a quantum mechanical limit on why plants might be green at least in part. There are reasons to doubt that is the full picture as those green sulfur bacteria have no such need to use such high energy photons and some understory plants do use green light for photosynthesis showing that it isn't impossible to use it. My suspicion is that the reason will be due to heat as chloroplasts need to be kept within a narrow window of temperatures which plants usually do via evapotranspiration. This coupled with the generally bad outcomes that occur if low light adapted plants are suddenly exposed to full sunlight suggests that it may be a case of too much activity in their photosynthetic reaction centers which would be supported by some plants algae and cyanobacteria in high intensity light conditions adopting red pigments (which people will also sometimes breed into plants too I should note).
I suspect it is a combination of both of these effects base don what I have read but more research is needed and there is evidence that at least in the case of oxygenation the standard narrative is wholly insufficient.
In the case of Boyajian's star perhaps the long term dimming and the possible collision were related? After all the Ordovician Meteor event was a major collision between two asteroids which created a lot of debris which may be undergoing secondary collisions during the interval of several million years where such collisions are much more likely.
Dr. Kipping echoes my thoughts on UAP's from the get go though my immediate though was skeptical from the get go but I tend to be very skeptical most of the time fore this kind of stuff. Keep an open mind and be aware of possibilities but be skeptical especially with god in the gaps mechanisms as gods, aliens or fairies(which seem to have been the predecessor of UFO/alien sightings).
The real issue is the other transuranics above the table from plutonium. Some of them have no stable isotopes, and some have very short half-lives, I think the longest lived isotope of Einsteinium is just over a year. So whatever is going on, it's actively replenishing these elements if the observation and interpretation of the spectra are correct. So if it was a kilonova, we'd know, because it would have had to happen sometime the previous year. We'd see that. Another option is bombardment by a neutron star, but again, it would need to be active or recent, and there is no neutron star there. There are just very few possibilities for it when you account for the very short half-lives of some of these elements. That said, it really needs confirmation to ensure that these elements are really there and being interpreted correctly. That's step one. One other aspect though is that they could be decay products of more stable elements higher up the periodic table in the so called island of stability, if that exists. We've never synthesized any of that stuff, so it remains theoretical, but again it's unclear how this single star could do it, but no other star we know of does.
Tabby's star is a different story of course. Yes, I think the case can be made that the long term overall dimming could be due to a dispersion effect after a collision. Consistent with this is the overall decline in the depths of the dips that have been subsequently observed. They aren't the really severe 22 percent dips anymore, more like 1-3 percent, which seems like dispersion. Trouble is, there should be infrared visible, warm dust afterall and observations didn't show that though the JWST observations might whenever they come out. So that led to the cold comets colliding hypotheses Dr. Boyajian initially advanced, but that too has issues in that the profiles do not match exocomets and it would require an implausibly huge amount of cold comets to do it.
With UAP, all that's needed is some quality evidence and word of mouth accounts won't hit that bar. I simply leave it at that. I'll take a look at anything, and be open, but so far my bar hasn't been hit by anything.
@@JohnMichaelGodier Yeah if these more exotic transuranic elements exist in its spectrum that would change things though it might work well in the context of the so called island of stability. As for the neutron star from what I looked up in a not very comprehensive search none has been detected but there is still a possibility if it is positioned such that no radial velocity signal would be viewed from Earth that it could still be there, unlikely but not yet ruled out entirely. Wasn't there an object which is based on the idea a neutron star could sink into the interior of a star? I doubt it is the case here but something odd is going on.
The other explanation for the long term dimming with Tabby's star I have heard is that there might have been a gaseous planet that crashed into the star some time ago and cause it to brighten with the star slowly relaxing to its normal brightness with the odd dipping possibly being due to now unbound icy moons slowly evaporating away. Probably unlikely but its an odd star.
@@Dragrath1 There is, the neutron star engulfed in a normal star is a Thorne-Zytkow object. There are predictions about what that might do to a star, and there are candidates for it. You should see higher levels of calcium and lithium, but also elevated rubidium and molybdenum. You should also see higher than normal luminosity, which is not seen at Przybylski's star. But there are questions there, what does the spin of the neutron star do to alter the conditions etc. What's interesting about Thorne-Zytkow objects is that there's no reason they shouldn't exist physically.
With Tabby's star, the intrinsic to the star explanations have fallen short. There have been several, giant star spots, recently ate a planet etc, but what should be seen in such a case is periodicity as the star rotates and whatever blemish comes into view. You'd also expect the star to act strangely, Kepler could see variability in the stars themselves and much of it was very characteristic, short upticks in luminosity due to flaring etc. and Tabby's star was just behaving like a normal F-type star. The real key is to observe the star again and confirm the presence of those elements, and then look for other examples in type Ap peculiar stars.
The null result, not finding a moon might be more interesting for science, but I don't believe for a second that Dr Kipping is "hoping" for that to be the case.
I have followed his channel for quite a while and his dedication and passion for finding an exo-moon only leads me to hope that his name is forever linked to the first confirmed discovery of one. It makes it even more poetic if it is found around a planet he discovered.
Great interview John! I really enjoyed it. It is sad to hear the ignorance of David around UAP. I wish these folk would take the time to review the history before making judgments …this area needs as many scientific minds as we can get to understand this phenomena.
Its kind of a wierd status quo bias. A lot of these guys probably have more interest/belief in the subject that they let on, but to show it means ridicule. And show it to much and you might as well just change fields, because the entire community of science will literally turn its back to them.
Its an outdated stigma.
Much like the idea "The true knowledge of the government on UAPs would send civilization into a panic and the world would collapse."
Dude, you could prove they were real and ate here to feed on us and I guarantee 4/5 people would just turn the channel. 1/3 would believe it was lies even if president introduced them in a state of the union and told us everything.
Full disclosure would only confirm what we all already know, and for the rest who are self absorbed? They will be totally unaffected.
Excited for this one!
amazing discovery ❤
Why not use the Vera Rubin telescope. Seems it'd be better suited given it's extreme power.
Did we ever figure out what's going on with Tabby's star? JWST needs to look at these two stars ASAP.
We're not 100% sure on a SPECIFIC cause for the dimming, but AFAIK the dimming has by now generally been agreed to seem to be dust-based dimming, like that it has a partial dust-cloud around it that occludes the star to various degrees. The visual signal faded much more than its IR signature, as I recall, and we have other stars with similar 'less visual but not-so-less IR fading' behavior that we're pretty sure on the source of. So we're not SURE on what exactly it is, but I think only the nutjobs are still hoping it's an uneven Dyson sphere. The leading theory is a partial planetary dust cloud or the like.
So it's still a bit of a mystery, but only in details, not in "Are there aliens there or not?!" Ah, in fact, right from the Wikipedia page, "The latest results have ruled out explanations involving only opaque objects such as stars, planets, swarms of asteroids, or alien megastructures." The only big confusion about 'planetary dust cloud' would be that the star is a 'normal F-type' of adequate age as to no longer have a proto-planetary disk, so if there is dust, we aren't sure WHY there might be, even though we seem to think it to be the best candidate for 'what could cause the observed dimming'. There is no 'protoplanetary disk', but we think the proto-disk option is the best fit answer for what we observe...confusion! Maybe a planet broke up somehow, who knows. So the mystery of Tabby's Star is much REDUCED, but not totally ended yet.
My two most favorite guys, love it!
Regarding the UAP videos and pilots stating they've seen uap whilst flying.. I disagree with Kipping's point that of course things are going to happen sometimes out of thousands and thousands of flight hours and that sometimes pilots are going to get it wrong and think they saw something anomalous when they really didn't, so that it could just be pilot error. That's not taking into account AT ALL that various pilots have said there were times they'd see these same things every single day for weeks or months. That absolutely ISN'T just thinking you saw something anomalous once out of thousands of flight hours.
I think his argument is that during one million flight hours you will definitely find an entire squad of pilots that are all sky high on extasy, mushrooms, marijuana and other illicit substances.
