02/19/2025 - 12:25 PMThe Star Wars references are great

02/19/2025 - 12:25 PMI think humans are ignorantly arrogant to believe that there's is the only life in the in the universe and that life has to follow their plan to be life.

02/19/2025 - 12:25 PMThe Drake equation runs through my entire novel Hyperspecies, and how to get past the Great Fermi Filter is what the protagonist asks himself. Volume III is coming out soon. (on amazon)

@tylerfaubert1201
02/19/2025 - 12:25 PMI’m currently learning about this in my astronomy class at URI. One question that did dawn upon me was what if intelligent life was on a moon of a gas giant rather than a planet?

02/19/2025 - 12:25 PMI'd like to know the odds of the existence of simple life.
@nicoanazco9016
02/19/2025 - 12:25 PMShouldn't n_e be an integer?? He expresses it as a % and then a fraction, but if he defines it as the number of suitable planets it should be a whole number right?
@Gargamel-n-Rudmilla
02/19/2025 - 12:25 PMWater is very unique to Earth. The type of water on our planet is apparently very unique in the Solar system.
Water itself is a viscious solvent since it wants to bond with many things and it is imposdible to find naturally occuring pure water.
If you drank pure water it would strip the minerals from your sysyem and cause minor damage.
@Gargamel-n-Rudmilla
02/19/2025 - 12:25 PMViruses by the definition given are not alive as a self contained system they need other living things to facilitate or to make them come alive. Thus they are the first paracite, by definition they are parcities. They share the same origins as life or they could have started completely on their own and they are not part of the living tree but a separate tree. In either case viruses and living systems as defined are interdependent since complex cellular life could never have evolved with viruses since they enable our genes to be edited with other genes and thus mutations become more frequent than without viruses. Obviously their is a cost/price since a system infected by a virus will fight this invader and in that fight one party may die. If the host dies then the virus dies without its mission to multiply succeeding. If both can accommodate eachother then they will live together and form a new system.
Humans and other living forms have thus been tranformed by viruses and our DNA has been shaped by the people who have survived virural infactions.

02/19/2025 - 12:25 PM9:12 100billion planets in the solar system(its 8, NOT billion but 8 PLANETS)! How tf can ANYONE take this video it seriously? When you obviously don't know what galaxy, solar system, observable universe is? 🤦♂️ if you decided to use AI, at least know some very BASIC FACTS-because its just funny when you do videos, obviously without ANY knowledge what you even read…
@lainthor5808
02/19/2025 - 12:25 PMIt's a matter of time we meet aliens. I believe we are not alone. Or I think we r the earliest intelligent species in milky way to exist and the rest are still yet to come. Maybe we occured earlier. But there is defo other intelligent species out there. Can't be narrow minded. The space is so freaking vast bruv. Thinking gwe r the only intelligent thing out there is dumb. We can't even leave our solar system. I'm sure if there an alien civilisation there and they are able to galactic travel. They would have the tech to hide from us. We r too primitive and they observing frkm far. And not wanna disrupt our evolution just like we do with animals.
@miyukiteishi9051
02/19/2025 - 12:25 PMEven if the number of intelligent species is as low as 1 per GALAXY, how many galaxies are in the observable universe?
@scarmichael473
02/19/2025 - 12:25 PMMight want to check our Hugh Ross on his take on the likelihood of life on other planets – (the number may be FAR lower than you predicted…)

02/19/2025 - 12:25 PMHumans are very stupid why cause we are like kids ready to jump into a strangers vehicle as soon as they shout i have candy 😅
@OrchestrationOnline
02/19/2025 - 12:25 PMMissing from the Drake equation, or from almost every conversation of extra-terrestrial intelligence, is the concept that for all we know, every intelligent species is intelligent in its own way. The galaxy may be teeming with intelligence, but we may be the only species that defines itself with the word "civilisation," or sees exploration as an extension of ourselves.
@shaun5916
02/19/2025 - 12:25 PMSo why is it scary?
@kataseiko
02/19/2025 - 12:25 PMThe parameters of the equation get refined every time someone puts out a peer reviewed paper in the relevant fields. Currently, we are supposedly at a number close to 36. I wonder if more refinement will eventually bring that number to 42..
@Kirito-xh4zh
02/19/2025 - 12:25 PMI might be ignorant and obviously not a science major. But why arent we considering more factors, like 1) Time we had ability to detect said signals 2) Time it takes for transmission if its electromagnetic or something other 3) If we actually have the ability to detect them, we clear do not know how to detect everything like dark energy or dark matter. 4) Since everything we see through our telescopes is basically the past. Are we in the favorable place in our timeline for us to actually intercept their signal. 5) Biggest factor, do they actually want to communicate
@frankcuizio5375
02/19/2025 - 12:25 PMWe aren't ready to meet alien life.
Who do you think built the pyramids? It certainly wasn't us
@TheRealQuartz
02/19/2025 - 12:25 PMI feel like rather than just calling them "suitable planets" we should call them Carbon life based planets or just suitable to carbon based life.
@peterbauer7271
02/19/2025 - 12:25 PMIntelligence compared to what? We define ourselves as the wise ape. So we are smarter than other animals. I’m not so sure. To be able to destroy the planet and most life forms is no sure sign of being smart. In fact I would argue the contrary. As if truely technological aliens would waste there time talking to us.
@swoopify2044
02/19/2025 - 12:25 PMI've honestly never understood the concerns regarding whether an alien civilization would be friendly or hostile if we visited…
Think about it from their perspective: An unknown alien civilization you never could've known existed, suddenly show up at your home planet uninvited, and let's be honest – most likely armed to the teeth.
Do you really think they would start mindlessly killing on sight, or maybe they'd take some caution?
@PMangelfire
02/19/2025 - 12:25 PMWe might need to change the way we look at things. For the Drake equation, there have been other species on our planet with intelligence that rival our own. Our extinct cousins for one (Neanderthal). It has taken humans alot longer to get here than we care to admit.
@peterparker2651
02/19/2025 - 12:25 PMDamn Drake makes music and math formulas.
@LukaszSebastian
02/19/2025 - 12:25 PM"One hundred billion planets in the SOLAR SYSTEM"??? Several times in this video you mixed up the Solar System and the Milky Way Galaxy…
@Nick-bh5bk
02/19/2025 - 12:25 PMHas anyone ever tried adding in a variable for cybernetic civilizations? (thinking Borg-like) I suppose you could just include it in your intelligent life function, but something worth considering.
@richardcaves3601
02/19/2025 - 12:25 PMThe Drake Equation is best revised by adding in the factors identified in Ward and Brownlee's Rare Earth Theory. It adds in other critical factors like: the presence of a moon 25% of the mass of the planet and at just the right distance, the biological conditions needed for potential life to actually develop into single cellular organisms, then the huge jump needed to evolve to multicellular life, then the further huge jump needed to develop intelligence, followed by the conditions needed to develop technology, then the ability and curiosity to investigate space. The more Hubble, Webb, and other telescopes reveal about the absolute chaos and destructive nature of the galaxy and the vast majority of stars, the more our planet seems to be a total abberation.
@goofyiest
02/19/2025 - 12:25 PMwhat's with all the star wars models?
@Savage3OO6
02/19/2025 - 12:25 PMWe have more than one data point for how often intelligent life arises. First, life arose on Earth, but five mass extinctions happened, hence life had to reboot each time, for a total of six attempts at intelligent life. For example, dinosaurs had 165 million years to invent the wheel and failed to do so, but mammals pulled it off in less than half that time. So I'd make the argument that from the known data points, intelligent life arises approximately one out of six times.
@user-wy4mp9ts3u
02/19/2025 - 12:25 PMThe only problem with the Drake equation is that the universe is so large and could even be infinite or so big it can not be equated for so therefore no equation can enlighten us especially if that civilisation is highly advanced meaning if they can travel at greater than the speed of light they could be beyond the visible boundary of our universe which opened things up a very lot
@Denzao-D
02/19/2025 - 12:25 PMAlien life like us in milkyway. Unlikely. I mean. If the asteroid who killed the dinosaurs would hsve arrived 1 second later.
Dinosaurs would not have gone extinct. The asteroid would have hit the ocean. we where lucky because it hit a sulphur deposit. Just luck that we are even here.
I think bacteria and some form of animals is more likely.
That would still be awesome to find strange animals of some kind.
@henriqueacabral
02/19/2025 - 12:25 PMWho wrote this script? The misuse of “solar system” is ridiculous
@ricardoesco8146
02/19/2025 - 12:25 PMHumans are intelligent life… 😂 Lol tell another one

02/19/2025 - 12:25 PMEven things like plants can move to face the sun , Open their Butts…..
@brucemacmillan9581
02/19/2025 - 12:25 PMWhether or not there is any kind of life of any description outside of our own solar system is ultimately kind of irrelevant. It might be nice to be able to figure out, from a distance, if this or that planet in another star system definitively has life, but… we'll never be able to interact with that life (keeping in mind, it could be no more than microbes), as the distances are entirely too vast to be traversable.
@coffeetalk924
02/19/2025 - 12:25 PMI assume you meant to say any solution to the Fermi Paradox, not "any solution to the Drake Equation."
@stehponielove9861
02/19/2025 - 12:25 PMIf you're gonna call aliens from other planets other "races" then what do you call aliens of our own species from our own planet? 🤔
