    It is statistically impossible for life to exist on exactly one planet in the universe. Earth just isn’t that fucking special!


    Edit:

    A statistical impossibility is a probability that is so low as to not be worthy of mentioning. Sometimes it is quoted as 10−50 although the cutoff is inherently arbitrary. Although not truly impossible the probability is low enough so as to not bear mention in a rational, reasonable argument.

    If I’m wrong about the definition, at least I’m not wrong alone.

      Life is certain to exist, but multicellular life is less likely and intelligent multicellular who reaches for the stars is even less likely

        Who said anything about multicellularity, intelligence, or space travel?

        Point is, Obama’s answer was vacuously true, and the only answer a non-idiot could reasonably could have given.

        …Okay, I admit he could have quoted Contact for extra style points:

        “The universe is a pretty big place. If it’s just us, seems like an awful waste of space.”

        But aside from that, the answer he gave was the only one he could reasonably have given.

          Okay wait, listen to yourself. You expected Obama to give a reasonable answer, and of course he did. Gosh, wasn’t that nice? You might agree or disagree with his choices and priorities, but even his worst policies had SOME sort of reason behind them. And were stated in complete grammatical sentences that stayed in topic.

      If we presume a functionally infinite universe sure life pretty much has to exist in multiple spots. That’s a big presumption by itself though.

      After that, is said civilization on some dinosaur shit? Are they so far beyond us we look like cavemen in comparison? Are they looking around the universe and just missed us? Do we want them to find us? Historically humanity finds less advanced groups and kills, enslaves, or just robs them blind. No reason to think the alien conquistadors would be better then the Spanish ones.

          I would be very surprised if it was that far away to be honest. They estimate there are likely trillions of planets in our own galaxy now. For us to be the only one would be absurdly unlikely.

      It isn’t. Check out this talk by Dr. Kipping. If you role 1000 x D6, you might say it is statistically impossible to role that number. And you’d be close to right; it was very unlikely. But you did role it.

      eta: The number of people supporting the phrase “statistically impossible” is troubling. This is why it is a problem that prominent scientists have made similar statements based on intuition. It isn’t based on statistics. We do not have sufficient data to make binary statements about Drake’s equation, nor even really to make any quantitative statements about the outcome, but certainly not binary ones.

        As far as the history of the universe is concerned we are actually super early on in its lifespan. So in some ways it’s actually more likely that we will be one of the early civilizations that perish before the others show up.

          No. “Impossible” is an absolute statement, whereas “extremely unlikely” leaves a non-zero chance for the unlikely thing to actually happen.

              Exactly. That’s why I corrected that it’s statistically extremely unlikely but not impossible.

          No. Statistically impossible means that according to statistics it canNOT occur. Extremely unlikely means that in a given percentage of cases, it CAN occur.

    I’ve said it before, but Trump as president basically rules out the existence of aliens on Earth. That fat fuck could not keep his mouth shut if he knew about aliens.

    I have been rewatching the x-files, and the most fantastical part of the show is the idea that the FBI could orchestrate an alien conspiracy. Kash Patel couldn’t organise a piss-up in a brewery, let alone hide aliens from the world.

    It’s quite simple. If the US had evidence that aliens existed, do you think Donald Trump would gave kept it a secret? He would make a big show of insisting to be the guy who they talk to when they say “Take me to your leader”, and he wouldn’t be able to resist telling us all about it.

    Obama clarified his comments on Instagram:

    I was trying to stick with the spirit of the speed round, but since it’s gotten attention let me clarify. Statistically, the universe is so vast that the odds are good there’s life out there. But the distances between solar systems are so great that the chances we’ve been visited by aliens is low, and I saw no evidence during my presidency that extraterrestrials have made contact with us. Really!

    What’s crazy is that Trump would never say anything even half as intelligent as that.

    If extraterrestrial, sapient alien life has been discovered here on Earth by the US government it was probably uncovered via signals intelligence gathering. Not via any sort of physical interaction or visual observation.

    Everyone thinks that to find aliens you need to search the skies, looking for visual evidence or radio patterns. No one bothers to think that a mass surveillance network across the globe would pick it up first—from local sources. Meaning: They’re already here and could have been for hundreds of thousands of years (or longer).

    There’s probably an autonomous alien monitoring station broadcasting information about Earth on the regular. Probably more than one.

    Exactly the type of thing that would be investigated by signals intelligence analysts who spend their days trying to figure out, “WTF was that?” Looking at data gathered from all over the world (for spying reasons).

    That’s why Obama would laugh at the question of, “where are the aliens?” Because he wouldn’t know! He’d just know that they’re here… Somewhere. Probably just super advanced machines, connected to a quantum-level universe-wide network.

    The real question to ask is, “are they enjoying our memes?”

    Does alien life exist somewhere? Yes. Absolutely. It would be impossible for it not to given the size of the universe and the laws of probability.

    Is that alien life multicellular? Again. Yes. For the same reason as above. In a functionally infinite universe, the roll of the dice is going to come up at least a few times.

    Is that alien life intelligent? Maybe. But in my opinion, probably. Intelligent life arose here after many many stops and starts. It’s probably that given enough kicks at the can, multicellular life can evolve intelligence on any planet where it arises if the conditions are right.

    Has that intelligent life visited us? No. No intelligent life has ever left their own solar system except possibly in the form or a one-way generation ship.

    Life evolves, either biologically or technologically, because of competition for resources. From the most basic amoeba competing for the heat from a steam vent at the bottom of an ocean, to humans competing for oil and minerals, life is about resources gathering.

    So what happens when we finally are able to access the resources of the solar system, which are effectively limitless (at least from a human perspective)? Nothing. We stagnate. There’s no impetus to go further than that. Scientists may want to. But pure science is a myth. People paying the bills are what drive us forward. and it’s reasonable to assume that any life that evolves would do so facing the same pressures.

      Any physics grad can tell you that life visiting earth from another planet is impossible, because with absolute proof we know physics is truly universal.

        Life finds a way…if there is a reason to do so.

        My point is, once we’ve secured all the resources in the solar system, there is no reason to find a way.

      we always find ways to use the virtually limitless and some people always want to push the boundaries. We certainly, if limited to what we know now, use lasers to accelerate solar sail ships or some such with some other engine for braking or such. That is if we don’t just straight out find some new technology once we understand physics more.

    I think his comment was really just him acknowledging UAPs and referring to them generically as “aliens”. That’s why he’s never “seen” them. He can’t confirm or deny little green men in these weird flying craft so his answer is he believes but he has not actually seen one.

    Or he was just being cheeky for a fun clip. 🤷‍♂️

    We know they’re real, and we know they are here. This is old news to us in the UFO/UAP/NHI community.
