Новый анализ показывает, что в галактике Млечный Путь могут быть сотни миллионов обитаемых планет
And thats just the milky way galaxy.
It’s estimated that there are about 1 to 2 trillion galaxies in the observable universe, and each of these galaxies may contain anywhere from a few million to a hundred trillion stars. A commonly cited conservative estimate is that there are around 1 septillion (1 followed by 24 zeros) stars in the observable universe.
Okay so surely there’s at least 10 other space-faring civilizations, statistically speaking. I mean come on. JUST us? That’d be… really weird.
I got dibs on one of em.
It’s really starting to feel like we are possibly getting prepped to find out we are 1 of an infinite number of (semi)intelligent species amongst universes across multiple dimensions and we are very far from the most advanced. Humbling to say the least, ground breaking at average and earth shattering to the fragile. The delayed disclosure and dribbling of information all makes sense, nothing will ever be the same if only 5% of all this is truth.
Obviously believable but what I always hate about this discussion is, why are humans trying to quantify habitabaility for an alien civ? We have to accept other species could work completely different from us or even more bizarely, if you believe the common claims in this space; are of a completely different dimension.
Controversial take: all planets are habitable, only the type of life changes.

pnas is highly credible, second most cited journal according to[https://en.wikipedia.org/wiki/Proceedings_of_the_National_Academy_of_Sciences_of_the_United_States_of_America](https://en.wikipedia.org/wiki/Proceedings_of_the_National_Academy_of_Sciences_of_the_United_States_of_America)
imho, simplest explanation / occams razor is that nhi probes have been crashing on earth, similar to the voyager 1 probe we sent out.
Every time I hear Milky Way I think of the chocolate. Why am I such a fatass
I just want to find OA and become a GL already
How come there isn’t one massive object somewhere in the universe which was originally the heaviest and therefore started a chain reaction of pulling all nearby matter towards it, eventually colliding and then creating a larger mass as more objects are pulled and then from farther and so on
It’s been 6 gorillion years or something so there’s been enough time for my ultra massive stellar mass to gather enough to be pretty sizeable imo, thoughts on theory?
“New analysis reveals”
Bruh the Drake equation has been around since the 60’s
Not after Humans get to them.
I believe there’s probably alien life of some sort out there in the universe. But since I like to argue against myself I thought i’d share this video: [https://www.youtube.com/watch?v=zcInt58juL4&t=1025s&pp=ygUld2h5IHdlIGNvdWxkIGJlIGFsb25lIGluIHRoZSB1bml2ZXJzZQ%3D%3D](https://www.youtube.com/watch?v=zcInt58juL4&t=1025s&pp=ygUld2h5IHdlIGNvdWxkIGJlIGFsb25lIGluIHRoZSB1bml2ZXJzZQ%3D%3D) David Kippling gives a lecture about how it’s possible we could be alone in the universe, not that we are. He goes through the reasons people state there has to be life out there, and tackles the drake equation and talks about the probabilities we don’t know (i.e. chances life starting on a planet of a certain type). It’s worth a watch.
271,000 stars are within 1000 light years of Earth. 10,000+ stars within 100 light years. If we manage to go another century without nuking the planet, we could conceivably create interstellar probes. Or from another perspective, a civilization needs to survive ~200 years post-nuclear weapons to start having an intergalactic presence.
Pre-nuclear weapons you can’t really destroy your planet/civilization. So even the worst type of war is recoverable. We’ve already come ~80Y since the first nukes were created. Perhaps ~60Y since creating nukes that seriously threatened civilization. So that is 1/3 of the necessary survival already.
The idea that all intelligent life destroys itself before leaving its imprint on the galaxy seems unlikely. There seems to be a fairly narrow window between nuclear technology and interstellar exploration, even if only through machines.
Maybe they just can’t be arsed to communicate
Hundreds of millions of habitable planets in the galaxy and humans were the second species to discover fire on this relatively young one.
Habitable for human beings? Likely hundreds.
Habitable for bacteria and single-celled life? There’s likely hundreds of thousands of planets, moons, and other astronomical bodies capable of harbouring basic life.
Most of the hundreds of billions of star systems in the Milky Way galaxy are going to have some form of solid body in the Goldilocks zone.
We need to develop a better understanding of how life on Earth arose and was sustained before we can judge any planet to be truly habitable, though. And for now we have no way of knowing if any of the exoplanets we have observed have atmospheres capable of shielding the surface of the planet from cosmic radiation, which is the big kicker when it comes to looking for life.
We’re super young compared to the age of the universe. Like, if at all human-like species existed since the beginning, imagine the level of advancement. I feel that if we’re in the year 5,000 (based on how we rapidly develop) or something, we would be looking back at our «cavemen» era 21st century about how we were still fighting for alien/UFOs disclosure when in the 51st century we have already colonized other planets and working with other species.
100 billion or so stars in the galaxy.
Damn, imagine being born the strongest creatures in the known universe, surely it would get to their heads, especially when meeting beings beyond their known universe that are superior, lol. 🤔
Yep, but without FTL, it is going to be hard to visit them.
What are you crazy? No way, religion and Mick West told me it’s not possible.
And we arleady have THREE other celestial bodies in the Solar System that could very well have life: Titan, Europa and Enceladus.
The notion that we are alone and the universe’s greatest creation is so damn arrogant and awful.
*Titan has a lot of oil too, just don’t tell murica*
No kidding. In a huge swath of an infinite universe?
Only one of those needs to be inhabited by aliens who are sufficiently advanced to be able to send self replicating drones to capture the whole galaxy in less than 400 thousand years.
I sadly suspect the solution to the Fermi paradox is that we are indeed alone. We are less than 14 billion years into the existence of this universe, that is projected to last trillions of years. We aren’t even at 0:15 am right now. I think there’s a good chance we’re the first sentient race in an impossibly large radius of space.
With an ever expanding universe it is impossible for Earth to be the only planet with habitants.
Theres also at least 100 billion planets and our milky way is around 100,000 light years across.
Even if all those habitable planets contained advanced life the chance of them finding and reaching other would be slim unless they were lucky enough to be 2 advanced lifeforms in close proximity and one is advanced enough to travel to the other.
What humans have a hard time accepting or comprehending is the idea that there are more intelligent “human-esque” creatures out there. We’ve told ourselves for a long time that we are the stars of this story. That we will discover life and populate the universe. That we are “Gods@ people and the masters of the planet.
Hard for people to imagine that we actually aren’t at the top of the food chain and that aliens have been watching us forever.
And that’s habitable to us. We have no idea if life evolves the same as on our planet there may be planets that seem crazy to us but life evolved on
All of a sudden
Off topic
Is there any milkyway galaxy map like Google maps?
This article makes the mistake of conflating habitability with being within the habitable zone. They are not the same thing, for example both Venus and Mars are considered within the habitable zone but they are obviously not habitable:
[https://exoplanets.nasa.gov/resources/2255/what-is-the-habitable-zone/](https://exoplanets.nasa.gov/resources/2255/what-is-the-habitable-zone/)
However there may also be moons that are outside the habitable zone that can have life.
It’s also possible that life on Earth didn’t emerge here but that it came from space:
[https://en.wikipedia.org/wiki/Panspermia](https://en.wikipedia.org/wiki/Panspermia)
And that might mean that complex organisms are incredibly rare. Building blocks of life such as DNA might have had to emerge in one type of environment, then migrate to another environment in order to evolve into cellular and multicellular life.
We are the Ant-Farm.
You don’t communicate with your ants, you just watch them build & fight from a distance.
We can’t even fathom the intelligence of intelligent life…
I thought planets of M class stars were likely to be tidally locked, which would further limit the habitability.
Habitable, but not by us. Our current physics doesn’t allow us to get there.
How do they know unless the space force is far more advanced than we know
This is an interesting development. The big issue is tidal locking. The stars are so dim that the «habitat zone» where the planet has to orbit will be so close that the planet will likely be locked to the star. M stars also tend to be flare stars and being close to one might result in sterilization.
