The 2,500-year-old argument about whether planets are common is settled: every star in the night sky has planets.
In which case, those kinds of collisions are so rare that you would expect one in a trillion stars to have planets. Instead, every star in the night sky has planets.

The universe has run ten billion trillion habitable-zone experiments, so we are the first technological civilisation only if every single one of them failed.
And so, what we found was basically that there have been 10 billion trillion habitable zone planets in the universe. And what that means is that those are 10 billion trillion experiments that have been run. And the only way that we're this whole process from a biogenesis to a civilization has occurred is if every one of those experiments failed.

The burden of proof about alien civilisations has shifted: it is now on the pessimists.
But I felt like what this paper showed was that the burden of proof is now on the pessimists. So, that's why we called it the pessimism line. Throughout history, there's been alien pessimists and alien optimists, and they've been yelling at each other, that's all they had to go with.

There is no Fermi paradox from the great silence: nobody has looked, for the entirely mundane reason that nobody funded the search.
So, we'll call that the indirect Fermi paradox and there absolutely is no indirect Fermi paradox for the most mundane of reasons, which is money. There's never been any money to look.

Every SETI search ever conducted adds up to sampling a hot tub's worth of an ocean, so finding nothing tells us nothing.
And what they found was if that search space, if the sky is an ocean and you're looking for fish, how much of the ocean have we looked at, and it turns out to be a hot tub. That's how much of the ocean that we've looked up. We've dragged a hot tub's worth of ocean water up and there was no fish in it

The hard steps model of intelligent life is suspect: none of the steps it names turn out to be hard.
But what we actually found was that none of those are actually hard. The whole idea of hard steps, that there are hard steps, is actually suspect. What's amazing about this model is it shows how important it is to actually work with people who are in the field.

Life does not happen on a planet, it happens to a planet: the fate of a world and the fate of its life are inextricable.
Life and the Earth co-evolve. That's what Brandon Carter didn't see is that actually, the fate of the Earth the fate of life are inextricably combined. This is really important for astrobiology, too. Life doesn't happen on a planet, it happens to a planet.

Our technosphere is immature: it is currently destroying the conditions it needs in order to sustain itself.
What we were arguing in that paper is that it's an immature technosphere. Because right now, with climate change and all the other things we're doing, the technosphere right now is destroying the conditions under which it needs to maintain itself.

The Earth does not need saving — the biosphere will outlast us; what is actually at risk is the narrow band of conditions humanity needs.
The biosphere is not going away. There's nothing we could do. The idea that we have to save the Earth is a little ridiculous. The Earth is not a furry little bunny that we need to protect. But it's the conditions for us.

A Mars base is not a backup plan for climate change or nuclear war, because self-sufficiency there is centuries away.
So, trying to establish a base on Mars it's going to be so hard that it is not even going to be close to being self-sufficient for a couple a century at least. So, it's not like a backup plan now, we have to solve the problem of climate change, we have to deal with that.

Life is going to be common in the universe; the genuinely open question is how long technological civilisations last.
Intelligent life and how long intelligent, technological civilizations, I think there's a big question about how long those last. And I'm hopeful, but in terms of just, I think life is absolutely going to be common, pretty common in the universe.

The Kardashev ladder ignores the second law: harvesting a planet's worth of energy produces waste heat that changes the planet's climate.
There's the first law of thermodynamics, which is just about the different forms of energy. Then there's the second law, which is about when you use that energy, Kardashev wasn't thinking about the second law. If you get all that energy and you use it, there is waste heat. You don't get to use it all.

Every technological civilisation probably triggers its own planetary climate crisis.
Does every technological civilization trigger its own planetary crisis, its own climate Anthropocene crisis? And the answer we actually came up from doing models was like, yeah, probably.

We should not be broadcasting powerful, easily detectable messages into interstellar space, because we have no idea who would receive them.
I don't think it's necessarily a bad idea to have your head below the grass. The people who advocate like, "Oh yeah, we should be sending powerful messages that are easily detectable into interstellar space." I'm like, "Why would you?" Because we just don't know, I'm not going to say they are warlike. I'm not going to say they're not warlike, I have no idea.

No UFO or UAP data comes anywhere near the standard of evidence required to claim non-human technology.
I am all in favor of an open, agnostic, transparent, scientific investigation of UFOs and UAPs. But the idea that there's any data that we have that links UFOs and UAPs to non-human technology, I just think the standards, none of what is claimed to be the data lives up to the standards of evidence.

The visiting-aliens story is incoherent: a civilisation with the technology to stay hidden would not keep being spotted.
Like, okay, there's an advanced civilization that is visiting Earth regularly. They don't want to be detected. They've got super powerful technology, but they really suck at using it because we keep seeing them, we keep seeing them, but then they disappear. I mean, explain to me what rational world that works under.

Every faster-than-light proposal depends on exotic matter, which does not exist and was invented to make the equations behave.
But here's the problem with all of those proposals is they all need something. The thing you added, the little fictional term you added into the equations is something called exotic matter and it doesn't exist. It's really just something we dreamed up to make the equation to do what we wanted them to do.

Expecting technology to keep accelerating is a bias of our particular moment; for most of human history the tools did not change at all.
So, we could be fooled into thinking like, "Oh, technology's going to go on forever, we're always going to find new advances." As opposed to sometimes things just flatten out for a long time. So, you have to be careful about that bias that we have living in this time of great acceleration.

Alien life should converge on things like legs and wings, but the humanoid body plan is a random accident nobody should expect to see repeated.
And this is important, so yes, you should expect legs or jointed sticks, how many joints they're going to be? Anybody's guess. Do you expect humanoids, things with a sensing apparatus on top of a shoulder with two arms and two legs? That's probably a pretty random set of occurrences that led to that.

The true unit of life is not DNA and not the cell but the biosphere — the whole community.
Because the bacteria, even though they're individual examples of life, and I believe this the true unit of life, it's not DNA, it's not a cell, it's the biosphere. It's the whole community.

Large language models will not get to real agency, because a mind has to be embedded in a world through a body.
But they said, "Look, in the end, actually the only way to actually get a real brain in the VAT is actually to have a brain in a body." And it could be a robot body, but you still need a brain in the body. So I don't think LLMs will get there because they can't. You really need to be embedded in a world, at least that's the E-four idea.

The most important question in physics is what life is — what makes a cell different from a rock, and how agency arises at all.
And what I've come to now is the most important question for physics is, what is life? What the hell is the difference between a rock and a cell, fundamentally? And what I really mean by this, this is where I'm going to go non-traditional, is that really the fundamental question that is agency.

Science has come to treat its formal systems as more real than the experience they were abstracted from: 60 degrees as more real than hot and cold.
And then we end up at the bottom of that with this idea of everyday I wake up and I check my phone and I'm like, oh, it's going to be 60 degrees out. Great. And we start thinking that 60 degrees is more real than hot and cold. That thermodynamics, the whole formal structure of thermodynamics is more real than the basic experience of hot and cold that it came from.

The many-worlds interpretation invents infinitely many unobservable universes to avoid what quantum mechanics is plainly saying: that measurement matters.
Many of them try to pretend the measurement problem isn't there. Go to enormous lengths like the many-worlds interpretation, literally inventing an infinite number of unobservable parallel universes to avoid the thing that quantum mechanics is telling them, which is that measurements matter.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.
