Hey John, I’ve probably listened to every episode of event horizon, and dr petkowski is definitely one of the best guests you’ve had- glad he keeps coming back! He has a particularly logical and unconstrained perspective on life in the universe. Great chemistry between the two of u as well. Thanks for all the excellent content, keep it up good sir!

I loved Dr Petkowski's viewpoint right from his first few sentences. Ascribing any amount of importance to any characteristic just because that is how it happened here seems to me to be a flawed method. Obviously having a moon affected life on Earth and perhaps life would not have taken on Earth without the moon but it is a big step to then assume that a moon is necessary for life elsewhere. There is an extremely large number of arbitrary things to apply the same concept to if thinking along those lines. Moons, plate techtonics, volcanism, surface water to land ratios carbon dioxide or any other gas levels in the atmosphere etc. The danger is narrowing our search for life too much and possibly missing something right under our nose. Obviously we have finite resources to search with and some criteria has to be placed on what types of planets to look at. So I think we need to be very carefull of what we exclude and why.

John, is Brian Cox coming on the show? He’s really interesting and his soothing voice would make me sleep for days. Edit: to the people that didn’t get it. Brian Cox is awesome, and the sleeping thing has been a long running internal joke on this podcast

Always an excellent discussion with janusz. And you let him talk which is very respectful.

Always one of my favorite shows; thoroughly enjoyed this episode! Thank you to everyone involved in making it!

We should send a probe to fly through these clouds and capture samples. Seems fairly straightforward unless gravity is too strong where we'd need to fly

I had a book when I was a kid that speculated about gas filled creatures existing in the clouds of Venus that were like living hot air balloons.

what bothers me is that we have this inconclusive signal- on the planet NEXT DOOR.. imagine the controversy in confirming a signature on an exoplanet 1000s of light years away

Very interesting video. As always, I look forward to Event Horizon videos.

If life is found on Venus or the ice moons I feel that wouldn't discredit our moon being crucial for life. I feel it would switch the question to one of evolution.

Yes, bring Brian Cox on the show. Love to hear his analysis of our universe.

Thanks so much for the upload. I wish you All the best.

Great episode John. Dr Petkowski has a lot of interesting ideas.

Thank you for making this content so consistently

Excellent guest, as always.

Very cool! I think Dr. Petkowski is correct that we get fixated on thinking any planet would need to be like ours to have life and that all life would be similar to us. There's no reason to think that though.

The absolute 'luna-cy' of this topic! Another enjoying video!

18:00 I suspect planetary magnetic fields are important in the evolution of nervous systems. Any molecule that self replicates might take advantage of the light speed cavitation pulse, caused by energy from the local star following the field lines, to relay information or just an electro-chemical charge.

Greetings from germany :) Love your work!

Hands down favorite episode until now.

Petkowski's point on Zoo Hypothesis that at least some civs/ even individuals from such civs would still be interested in us would just conform to what we observe if the best UFO cases are ET

Amazing insights Dr Janusz!

i love this guest. something about his enthusiasm and utter knowledge is mesmerizing to listen to

Right on cool video!!!

Great interview Thanks!

Thx! More please!

John, Please get Professor Kipping back on to discuss his breakdown of the FTL breakdown and how he broke the theory.

All the best from Ireland John

I think that we should also try to look at nebulous gas clouds, dust clouds, even stars themselves for life.

Dr Petkowsky said it best, human galactic domination. Don’t mess with Earth!

Fascinating.

Interesting ep.

I personally can't understand how and why channels who talk science, started by accident to talk about science/psychics because one video had success or total amateurs who don't understand but reading the documents... Have so many subscribers, but quality channel like EH with JMG ís well known and respected in the scientific community have 10 to 20% of subscribers as they do. Sometimes you wonder to sacrifice quality for quantity and more subs, but that will hurt us all who truly love this channel, I don't know how many times I fell asleep listening and continue tomorrow and did again but surely I listen every episode few times, and if the theme is something that I really enjoy I listen every few months at least. So my question is why other channels who have not so good content compared to the EH or JMG channels, have so much more subscribers even tho their content cannot get close to the EH. I will never understand that, no really, it's true.

Nice topic

Thanks Lord there is a new video in this channel so I can finally get relaxed and sleep for some hours after a long time awake.

I love this channel

I think the most ideal place a galactic civ would settle might not relate to material arguments, as resources might not be much of an issue to them. It might have to do with aesthetics, uniqueness or driven by the civ's cultural characteristics. Kind of how the theory of the pyramid of Maslow describes the order of fulfilling needs.

The development of the universe up to this point seems like the process of a Chef 👨‍🍳 whose mom is Italian and dad is French. There seems some room for individual flair and substitutions, additions, subtractions, but overall to get the fluffy, crispy, salty, sweet, goorific dessert humans are wouldn’t happen without a fairly long and defined process. I bet simple life is relatively abundant with intellectual organisms being super rare. It seems stability of parameters is needed with a gentle mixing/cycling, but also every now and then when the thing gets stuck in a loop a brick threw the window is helpful.

The presence of a large moon might have bumped a few factors which made life on earth more possible. However there is nothing particularly weird about our moon and the Earth-moon system. Statistically there has to be many similar arrangements in our galaxy, let alone the Universe.

You should introduce your guest after the in video advertisement... So we don't automatically tap tap tap past their credentials. Honestly, 99% of us are tapping forward till the episode starts, cause no one wants to hear advertisements

"Nobody ever says 'why do we study cats...they're so stupid'" -Isaac Arthur

Pretty everything I did in the lab required specific temperatures, mixing, and stability of those over time. So thinking one needs warmth but not too much, moon influences but not too much, etc to get where we are is not an extreme hypothesis. Of course we don’t know for sure. We don’t know for sure water or carbon is needed for life.

The entire "Jelly doughnut" thing is a matter of context. In this context everyone knew he was talking about being someone from Berlin. If he had said "I would like to eat a Berliner" no one would think he was a cannibal. Which is why it was so surprising when he had cooked at eaten a resident of Berlin.

In my headcanon , JFK absolutely was a jelly donut.

This channel is just a jewel of the internet.

Could you have multiple origins of life on a planet? Say in the deep ocean and landbased. Only we can't tell the difference because they're using the same chemicals from the planet?

I'd go near a black hole where time dilation would give me plenty of time to get even more advanced in relation to others

If I could go anywhere, I would go everywhere. It's colder at the galaxy's edge but there is also less energy to harness.

For planets with a high carbon dioxide atmosphere. Given that plants release oxygen as a byproduct of photosynthesis, it could be hypothesized that an a form of fauna might develop gills, lungs or a simple bacterial membrane to extract oxygen from carbon dioxide.

Anna would be the perfect voice for the "computer", (an AI naturally), on the next Star Trek.

Living things are motivated, consciously or otherwise, by a desire to prolong their genetic code. What would motivate machines? And what would be the selection mechanism for evolution of the machines? What does it mean by a machine "civilisation"? Would there be machines each with its own individual goals, collaborating to maximise each one's goals or would it just be like a beehive with everyone working towards the same goal?

I Fkn ❤ Petkowski and Event Horizon 🎉

I'm a long time listener and I used to love this channel and look forward to Thursdays but lately the sound quality of the interviews are awful and make them difficult to listen to. Such a shame.

Get David Fravor on your show!

I'm a bit old to learn a new language. My uncle always said that shouting at people in English works quite well. 😁

ofc its protomolecule

OMG, it's Dr.Strangelove!!!

What would happen if we were able to move ceres or even Pluto into position to become a large moon of Venus? With the pushing in the pulling on the planet cause its core to liquify again and start a magnetic field? And if we tried to move Pluto to the inner solar system will get begin to sublimate and fall apart?

Totally not related, but... Ich bin wirklich ein Berliner! In Berlin, we call the jelly-filled variety "Pfannkuchen", whereas pancakes are Eierkuchen. Now, back to the program...

Yet another video with Janusz? I think you might be spoiling us John! Don't mind if you do..

Ich bin ein lekker piano

If we found life on Enceladus or another ice moon, it would mean life originated ON THAT BODY IN THAT MANNER. It would NOT indicate life began HERE that way. Life could have began in multiple manners independent of one another on Earth for a variety of reasons. This could be why we have fungi and octopuses.

My favorite channel by far along with your other one the subject matters you cover are perfect Never change !! Quickly replaced all the others I listen to since Joe rogan went to Spotify

ahhh, what a great channel :-D

New Fermi paradox answer: we’re on galactic covid lockdown for eternity

A "Berliner" is just a common term for a type of pastry in Germany. It's also just someone from Berlin. It'd be like if someone said in English went to Naples and said "I'm a Neopolitan". Obviously you understand it as they are someone from Naples but you could also technically interpret it as them being a type of ice cream if you want to be silly or obtuse.

I learned that in Norwegian, the word "fart" means speed.

My question to this is, "just becuase we haven't detected life yet, doesn't mean it's not there."

It's hard not to wonder what if the Earth is not as stable as we think it is...

"Where would you go?" Well... To be honest all I can think of now is my bed. Sorry. 😬

Wow the audio quality was bad on this one.

I would argue that Venus’ lack of a magnetic field may be responsible for its hydrogen getting blown away by solar wind.

Haven't been seeing the podcast version updating for a while now. What gives?!

Bring on Nima Arkani-Hamed plz

That’s interesting to think about, that if a species became a machine civilization and went out into space where would they go? They wouldn’t be where we expect to find life. They surely would be where it most benefited a machine civilization to exist.

if Alien intelligence detected and studied us, their fascination would be trying to figure out the point of our Species, and why we are extremely self detrimental.

Where's the follow up?

The moon came before us? Good work.

Maybe Venus itself is the life!

I think that the longer we branch out into space, the more we will evolve to handle it, but we may lose much of what makes us currently human, or homo sapiens. Perhaps, we will become homo solaris.

Shouldn’t be forgotten that intelligent behavior has evolved several times from complex life (cephalopods, mammals, birds) The speaker has ignored this fact. It seems to me much more likely that as complexity involves, the fragility of such life increases. A n asteroid may wipe out all complex life, but simple life might persist. There isn’t a “great filter” as such, but more of a mathematical relationship to express the complexity/fragility relationship. The issue really is, how long does a planet remain amenable to the development of a technological intelligence. Maybe we were closer to it at the Jurassic Cretaceous boundary and given another 10 million years one might have developed.

Glancing blow? Assumption at best John.

In the list of five thousand or so exoplanets discovered. Are there any examples of binary planetary systems? If not is this another thing we could hope for with JWST?

Speaking of Earth's geophysical characteristics and the role of the Moon and how important it is for life one interesting development in geology is that plate tectonics at least in the case of oceanic "plates" appears to extend far deeper into the Earth than has been historically assumed extending not just from the crust but down to the Mantle Transition Zone some 600+ kilometers. The depth of these circulation cells is quite interesting and may be in part driven by tidal stretching especially back when the Moon was so close. I have to wonder how different hydrothermal systems would be under extremely strong tidal events? The boring billion wasn't all that static as had been assumed in particular the interval saw the emergence of complex aerobic life with evidence that costal and freshwater environments were a center for complexity including multicellular algal fossils as far back as 1.6 billion years moreover given that modern surveys of life have found that the last common ancestor of modern cyanobacteria were As for UV light quite a few organisms on Earth actually utilize UV light to drive biological reactions including to a limited extent humans. At high altitude fungi perform UV trophic reactions as a source of energy thus really the UV argument. This has always led me to suspect we have the role of UV light quite wrong as there is potential evidence for an ecological collapse driven by the formation of the ozone though that is weak given the very marginal fossil record there. However notably chelicerates and myriapods despite their genetics suggesting they were present during the Cambrian but no fossils have been found yet. As for the Fermi paradox I think this isn't a problem given how little time we have been looking. That said there is building evidence that the galaxies that compose the local group have for most of the history of the Universe been star deficient astrophysical metal poor with most of the Milky Way's star formation picking up around 6 Ga with peak starburst around 5.8 Ga and with Sun forming near the base of the tail 1.1 billion years later around the time expected for neutron star binaries inspiral but when star formation is extremely high meaning r process nucleosynthesis would be extremely elevated. Is it a coincidence that the Sun formed around the peak r process nucleosynthesis within the Milky Way or is this hinting at a deeper relationship here? On another note there is an interesting thermodynamic case that suggests complex life arose and proliferated about as early as it theoretically could have based on thermodynamic phase transitions in the mantle permitting higher ratios of mineral hydrates due to a combination of quantum mechanically induced ecological constraints on sea levels . Turns out that the same quantum mechanical effects which make aerobic respiration the most efficient reaction to release usable chemical energy from organic molecules, make its inverse process aerobic photosynthesis the least efficient carbon fixation pathway by requiring a larger minimum energy wavelength of light to split water this high threshold notably also eliminating chemosynthetic reactions especially due to the attenuation of light with depth in the water column favoring anaerobic reactions in terms of their ability to fix carbon using less energetic longer wavelengths of light that can't drive the necessary reactions to split water as a source of hydrogen. Given the timescale for the first aerobic peak timing up to around when we think the continents first entered the trophic zone it seems Earth's oceans this can naturally explain the delay between the oldest evidence for aerobic photosynthesis (3.5 Ga) and the onset of the first Great Oxygenation Event(GOE) 2.5 Ga as well as the long delay aka boring billion between the GOE and the Neoproterozoic oxygenation event as the oceans away from coasts remained fully anoxic aside from the uppermost layers which were likely populated by Aerobic anaerobic phototrophs a diverse assortment of bacteria which cheat the system using oxygen to power aerobic respiration but performing anaerobic phototrophic and or photosynthetic metabolic reactions getting the best of both options. And yes these microbes while not as abundant as they likely were in the Paleoproterozoic or Mesoproterozoic they remain abundant today accounting for over 20% of the prokaryotic biomass in Earth's oceans by some estimates with them largely concentrated around the oxygen minimum zone in Earth's modern oceans. Interestingly the collapse of oxygen levels after the GOE appears to have occurred round the timing of the Vredefort impact which could be a coincidence but might indicate a link in these events. The second pulse of oxygenation is linked to a timing for a transition to the modern plate tectonics regime which thermodynamically is linked to the mantle supporting a large enough percentage of hydrate minerals of sufficiently low average density to drive hydrous mantle plumes allowing a much more direct and complex interchange of water between the mantle and Earth's oceans. At least one such plume system remains active today the plume feeding Mt. Paektu/Changbai with hydrous melt from the subducted Pacific slab so this process is again ongoing. Together these suggest that the late timing of complex life was most likely not a fluke though it is possible aerobic life could have been able to arise sooner without the Vredefort impact but that is challenging to test. Combine these two major factors neglecting potential complications like the Vredefort impact for now and you have a natural size dependent relationship between the timescale for complex life to arise and the size and conditions of a terrestrial world with water dependent life. The more massive a world or the deeper said worlds oceans the longer it takes for conditions to become suitable for complex life while smaller worlds have too little time to evolve given their rate of cooling without sustained tidal heating.

Uh ok, what happened to the rest of the show? You ended by saying you're going to a commercial and would be back to talk about a shadow biosphere, but instead the show just ended. What happened?

don harvey was here

Hi I'm a shy guy so can you say hi to Anna for me. Thank you so much.

On earth life appeared almost as soon as it could. It’s so resilient that the only way it will completely disappear is when our sun bakes our planet in the distant future. The building blocks are everywhere and the conditions necessary don’t appear to be particularly rare. We say life finds a way so if we extrapolate that to the universe then simple life pops up everywhere there is the materials and conditions that allows. I think after that though rather hit a series of lotteries to get to us. The jump to complex life, intelligence, technology.. all get rarer and rarer I believe. For example, something came to the other day that I’ve never heard mentioned before. How important hands with opposable thumbs are to developing our technology and even our intelligence. People say if the dinosaurs survived would they have gained intelligence and technology. The answer is obviously no because their anatomy wouldn’t allow for tool making, which in humans was crucial for further developing our brains, therefore intelligence and eventually technology. We happened to evolve from tree dwelling primates where the anatomical features needed for hanging on to branches was perfect to be re-used for manipulating tools. I’m not saying that it’s be unique in the universe but another layer of rarity that gets overlooked 🤷🏻‍♂️ Let’s say for example, humans and the other primates disappeared tomorrow. That would leave arguably the whales say as the most intelligent life on earth. Would whales ever become technologically intelligent. No because how could they?

At Venus?

That accent is insane, where is it from?

Astrophage

Janusz is becoming a bit of a regular ain't he? He is very eager to educate and quite the life-positive chap ey? Those gasses in Venus have a few non biological theories surrounding them too. More nuanced voices speaking on the show would be nice actually.

Hmm... going for a break... and that's it? Not sure what happened there.

What's absorbing the U.V? The old Greek gods hanging out in the Venusian atmosphere.

Actually berliners don't call that a berliner rather a pancake (Pfannkuchen) FYI I'm quite certain though hamburgers call it a hamburger indeed ;)

Why is the FIRST assumption always "aliens" when in fact its never aliens.

If you name a title a question. . . the answer is usually "No."

I can provide no answers, however i can provide more questions
