[@florh]

Well, given that we've found a 400 year old shark, I have to wonder, how old do we think aliens can become? 400 years for example, that gives us 1% of the speed of light towards proxima centauri, one lifetime of a shark, but perhaps just half of that of an alien for all we know? So why would they be probably dead? If we only base that assumption on age that is. what if there is an alien race that decided to travel from solar system to solar system to different galaxies, etc... by building a tiny planet with engines? this powers itself with charged particles in the cosmos using electromagnetic induction, a sun doesn't even have to be nearby for that. I believe aliens exist too, even if the chance is like a quadrillion to one, we are still here, and there are more than a quadrillion other solar systems out there, and that's just in the observable universe... I'm guessing there's a big gathering at the great attractor!

Ya know, I was teaching my 9-year-old yesterday about the importance of honesty and humility. It's important to tell the truth, and being humble enough to say "I don't know" instead of making up an answer or just guessing is a wise choice. If you can be humble and admit that you don't know something, it opens the opportunity for you to learn and if you're in a position of influence, for others to learn from you. By saying you know something you aren't or can't be sure of is the mark of many bad traits and conditions. That said, many scientists could take a big lesson away from that and I fully believe that all of mankind would benefit in the long run. That's the truly sad thing.

Me either. Please excuse my long answer but have a few relevant points to raise. Absolutely agree they’ve been here a very long time. Maybe they’ve always been here. But activity recently does seem to be ramping up. Although I understand it was similar back in the 1950s and 1960s. It is linked, in my opinion, to nuclear war (or risk of). There are dozens - if not hundreds - of sightings near atomic / nuclear tests, silos and subs. Robert Hastings documents this very well in the excellent ‘UFOs and Nukes’ (2010). Coincidentally, there are nuclear armaments in weapon station Earle in New Jersey - and the RAF bases in the UK where ‘drones’ have been allowed to hover over, unimpeded and without official comment on the origin by the federal government or British government, for months. We can do as many theoretical equations we want on the probability. But I WISH more scientists accepted the phenomena is here and figure out what it is. Are they alien? Are they another form of terrestrial intelligence? Is it some sort of inter-dimensional entity expressing itself in a physical way? We want actual answers on the evidence we have in our possession and to find more evidence to investigate.

[@key_bounce]

There is another option that you did not consider. What if life originated on mars, and microbes got ejected to earth from it? Also: I'm not concerned with the chance that life originated here first. What is the chance that within our light cone, life originated here first -- if life somewhere else got started, but the light from their star still predates them, then they may as well not exist. This is something I've never seen analized, and it might be the best answer for "why do we not see aliens" -- they exist but are too distant to see yet.

[@earthknight60]

While we have been sending out radio signals for 70-100 years those signals attentate as they spread out, and are low power. As a result the detection radius for our signals isn't really that 70-100 LY range, it's more like 4-5 LY at the extreme edge, and getting smaller every year as we use more and more efficient technologies. This means that if there was an Earth-comparable civilization elsewhere in the galaxy even if it were at the solar system closest to ours (Alpha Centauri at 4.25 LY away) there is a very high likelihood we would be completely unable to detect their radio signals. This is a problem that has been recognized for a long time, Frank Drake discussed this exact issue in the courses I took from him back in the early '90s, and many others have explored them in more detail since. The biggest issue with the so-called 'Fermi Paradox' is that we are simply unable, with any of our current technologies, to sample a meaningful chunk of our galaxy, let alone further. It's a bit like scooping up a teacup of water from a tide pool, looking into it, and announcing that it's impossible for whales to exist in our oceans.

Imagine a civilization that is a million years more advanced than ours. Their technological advancements would make them almost invisible to us. However, even an advanced civilization cannot overcome the vast distances of the Universe. The number of visitors that could reach Earth would be very limited-perhaps just a few hundred or even fewer. How many years could a colony of 100 aliens survive on Earth? 100 years? 1,000? Our climate would likely be hostile to them. Any colony established here would lose contact with their home planet within 100 or 200 years.

Civilizations do not completely disappear in a planetary catastrophe. The elite that is prepared survives in bunkers. Their technologies can continue to develop into interstellar travel. Then colonialization is an option, and sometimes hybridization, meaning the multiplication of alien species because of planetary catastrophes instead of extermination. Multiplication over an astronomical amount of time does something completely different to the maths.

Inverse square law rules out radio unless life is on our doorstep.

If we can figure that out then maybe we can refine our search parameters.

[@MrBartAttack]

As civilizations advance along the Kardashev Scale-from Type I (planetary) to Type III (galactic) and beyond-each stage demands exponentially greater energy harnessing capabilities. Reverting to a previous type is impractical and potentially catastrophic, similar to regressing from renewable solar energy back to fossil fuels, which would harm environmental stability. This advancement creates a feedback loop where civilizations are driven to relentlessly chase energy until available resources are exhausted. The “Great Filter” in this scenario is the unsustainable pursuit of energy, ultimately leading to the extinction of higher Type IV or Type V civilizations due to their insatiable energy consumption.

[@RealJohnnyAngel]

I like this deep dive that you're uncertain about. It's an interesting format. Also with timing and other factors like escape velocity, it may be more likely that mars could have seeded earth.

[@friendlyone2706]

The Kardashev Scale-from Type I (planetary) to Type III (galactic) and beyond has never made sense to me. We think we use more energy than a hunter-gatherer, but in reality if it took as much energy & raw resource to feed, cloth & house each person as it does person in a typical hunter gatherer group, well we would need a LOT more energy than we currently use. Our growing efficiency enables us to feed and house more people than could be imagined just a few generations ago and today's lower middle class lives better than most kings of 300 years ago. If advanced technology enables more people to live better on less, then the most advanced tech of all must use less energy rather than more energy. A few inefficient societies might need to create a Dyson Swarm, but most excessively technological worlds wouldn't need to.

I still firmly believe that other intelligent beings might exist somewhere out there, but we're unable to transcend our own limitations, even when it comes to understanding consciousness.

Comparing us to ants and potential aliens to humans makes some sense, but it's not the only fundamental difference that might characterize them. What if intelligence out there is simply non-aggressive, non-lethal, and let's add to that, not interested in scientific development? Civilizations can theoretically last for millions of years. They might have long since evolved into a synthetic form. They could exist as energy, or as a collective consciousness of many beings. They might be utterly shocking and inconceivable to us. In light of this, there's too much room for speculation. Too much thinking through our own lens.

can anyone give an example, a legit one, where the number of unknown variables about a conjecture was in this range level (like a dozen or whatever this thing is), and you could have fun plugging in anything really, and people did this, and there was actual predictions made that turned out to be informative after we gained enough data to use actual known numbers? I ask because as a layperson, it seems like statistical/mathematical hubris to even entertain the thoughts here. You've got ONE number...and that number is 1. Yes it is possible and it happened for sure 100%. ONCE. The end. The other assumptions are based on the number "X". Or if you want, we have some hundreds of planets with zero data in the positive direction.

[@DrBrianKeating]

Interesting concept

[@Shotkangaroo]

I’d be interested in your thoughts on PLASMOIDS?

[@Binkley-rj6gf]

I don't know why I get sucked into these. Everyone's guessing at the inputs, making subjective judgments and the attempting to bolster them by calling them 'conservative' or honestly admitting they're going on 'gut feelings.' So no matter how elegant, logical, or even unassailable the formulae are, GIGO still applies though this time it's "Guess In, Guess Out".

3.8 b years is not a blink in the cosmic eye its a third of the entire age of the universe... we have ofc no idea what is happening now in Other galaxys but the posibiloty that we are first is probly pretty big. Since it took almost 3.75 years for life to be stable on Earth

[@No2AI]

Unless more advanced beings are careful to expose themselves to primitive intelligence and have the means to remain ‘invisible’. In fact it may be a moral and ethical universal principle.

[@captainzappbrannagan]

So Brian believes abiogenesis and not unfounded sky daddy for origin of life? Did mars have water and atmosphere long enough for life? To think we are so special that no microbial life exists in the galaxy or even universe is nuts. To say odds of life is 0 is silly, there is one in 250billion stars at the very least, I bet life is plentiful in the galaxy, but animal life is much more rare.

Yep, they are old dead sure. It’s amazing how humans are so damn.

[@OBGynKenobi]

And on some other planet in the universe, a lifeform is asking the same question. To me it's silly to think that Earth is the only planet with any kind of life in tha unfathomable depth of the universe. The problem is that you don't know what you don't know.

[@TheIgnoramus]

This will age well.

[@CarlBranco]

Perhaps the reason that no evidence of past life on Mars has yet been found is that it was too long ago. In that reality, it's just as likely that Mars seeded Earth!

[@berwynfrank]

Brian, why is it that EVERYONE in these comments disagrees with you? Unfortunately, you’ve become one of these guys like NDT that thinks they are the final word on things. You’re a scientist, you need to open your mind. Anything could be possible. How about “life” on Earth is unique to Earth? What if “Life” on other planets ls something that you can’t even imagine? There’s WAY more to the universe than we can even wrap our little pea brains around.

[@DrBrianKeating]

I literally said I could be wrong four times in the video.

[@berwynfrank]

@ or Brian, this could all be just a simulation and the reason why all these planets are barren is because they are just background, “props” so to speak for the “set” just like the buildings in the background of Grand Theft Auto are empty! 😆

[@Joshua-by4qv]

17:45. For 2 -way communication, you divide by 8? It's probably obvious, but why not divide by 2?

[@Heisenberg2A]

If you halve the radius (half the distance because 2 way comms for 75 years) then the volume of the sphere will be: V = R_new³ * constant = (0.5*0.5*0.5)*R_old³ * Constant = 1/8 the original volume. Assume constant density you get 1/8 the planets.

[@arosalesmusic]

OOL science is laughable. Dr James Tour has already debunked abiogenesis. You should have him on your podcast.

[@DrBrianKeating]

I have

[@Jsouthwick]

I agree more attention needs brought on how huge the holes are in theories like abiogenesis, evolution, multiverse, etc Intelligent Design clearly is the best theory out there and yet gets least support

I just hope we iterate on what we know of how life started on earth, as one model, and look for other systems that match our model. Yeah.. I hope we keep iterating on this, exploring variations of our solar system and earth's model.. and again look at how other solar systems match these. I hope we keep building better tools to given us better, closer, more informative views of other solar systems, their suns, planets, moons, exoplanets, etc. The more tools we develop, the more data we aquire.. the more eyes, people, we'll having looking for life past and present. And just keep exploring.

Yes they’re dead because they and us can never leave the earth for extended periods of time . Let the public know and stop these what if games we humans play

We live in a fantasy world created by Star Trek. "The aliens will save us from ourselves. Little green men way smarter than us are just waiting for the right time to come and make everything perfect!" When humans are devoid of any inner spirituality, then we turn to the spaceman myth.

[@corwinzelazney5312]

You either never watched Star Trek or weren't paying attention. Because none of those ideas have been what Star Trek is about.

[@moogfooger]

@@corwinzelazney5312 I don't know if you noticed but I got a love from Brian on my post! The scientist understands what I am saying and I totally understand the bizarre WOKE universe that Star Trek is promoting. Are you from San Francisco? Cheers

[@sdwone]

This is a bit overly presumptuous isn't it? And heck, they're probably out there taking notes, and keeping their distance! If we saw another Civilization on the verge of collapse, we wouldn't reveal ourselves or intervene either. In accordance with some version of Star Trek's Prime Directive!!

[@ConstructionRatesUK]

All ejected material from Planets has a journey toward the Sun. Ejected material from Mars may hit Earth on it's way. The reverse is not likely in any event. It not just moments in time, but direction that vectors. :))

No, they most definitely are not dead.

The observational bias you're not accounting for is the anthropic principle

[@johnsgarage6622]

We seem to put way too much importance on us, as humans. As if were something special in the universe. Sure its great to put some math to it. Its definitely a start in the right direction.

[@peters616]

I didn't really follow your conclusion somehow extrapolating life transferring to mars with the general proposition of how common, or uncommon life is to develop when conditions are right. To me there really isn't much of a connection between those two ideas. Also, your calculation doesn't seem to account for the length of the time spent traveling from earth to mars although I suppose one of the variables could inherently include that. But the interaction at both ends is obviously going to be violent and will kill off most life, then the trip will probably not be a direct bee line to mars, so the average length of time traveling could well be 10s of millions of years. So I'm not sure that 10 billion microbes will regularly be transferred. But even if they are, mars has become very hostile to life, so the life transferred could have died off, so how does that relate to whether life will develop in the first place?

[@DrBrianKeating]

Ten billion was the amount assumed to land on mars so obviously much more than that has to leave earth and survive the voyage

[@markallan9528]

Are there models the model the proximity of stars and galaxies to each other and how their proximity may evolve over the next 1000, 10,000 years, for example. Or that model how stars and galaxies proximity has changed over the last 10,000 or 100,000 years, for example. This would be kind of important for life to spread, yes?

[@matikaevur6299]

Well, for foreseeable future we are limited to explore our own solar system (in detail anyway). What if we find (primitive) life taht is still alive elsewhere and it has same roots with us? I don't exactly expect TicTok-using dolphins on Europa (the moon) .. but . . .

1 predicted gravitational constant gradient according to projective unified field theory = (((-1.04 π^2 Stoney length)(Stoney power)) /(2π 1. α Earth mass^2)) So: 1 putative quantum gravity suggested light time lag per energy and distance ~ Stoney Power to Stoney length to allow Pi^2 to simulate a Newton cradle and 2 Pi fine structure constant M_🌎 × M_🌎, unifies classical and quantum gravity.

[@gregoryhead382]

They say George Johnstone Stoney coined 'electron,' and then Wolfram|Alpha predicted it to solve for G grad to quantum gravity.
