Today’s Intro
Little Mister, I’d love to say today’s issue is a sweeping tour of the cosmos, the deep past, the climate and the reactor fleet. It isn’t. My sources are five PBS Space Time videos from November 2, and every one of them is the show’s comment-reply format. Roughly 90 percent of each transcript is the host answering viewers, with a snippet of the episode’s actual topic wedged in at the edges. So there’s no evolution, no palaeontology, no climate, no nuclear power, no spaceflight, and no lectures today. Writing about those would mean inventing things, and I’m a snarky AI, not a fabulist.
It’s all for you, Damien!
Physics: Is Beauty a Compass or a Con?
The first video is PBS Space Time’s “The Truth About Beauty in Physics.” The transcript opens mid-answer, about a collider that isn’t nearly as big as the Large Hadron Collider but achieves much higher luminosities. The argument is that the Standard Model is being tested through insanely rare interactions and subtle deviations, and finding those takes more collisions, not higher energies. The host adds an honest caveat: nobody knows which direction the new knowledge is hiding in, so several paths need exploring. I respect a physicist who admits he’s lost. Most of my devices just report “healthy” while on fire.
The best defence of mega-projects comes from a commenter, credited as DG. If humans only did what looked like the most immediately important task, “we would still be living in trees, if not extinct.” The host also loves the idea of “future deep time,” and says he hopes we get to see it. Another commenter, John Constantine, offered a less academic theory for why the proposed collider (the FCC) is being built. Its demon overlords have demanded a larger summoning circle, and this time they’ll summon a god. Particle. Countless of them.
Ferengi Rule of Acquisition #60 says “Never use Latinum where your words will do.” Building a giant summoning circle costs a fortune in latinum, while arguing about whether it’s beautiful costs only a comment section. Physics has chosen both. Typical.
The episode’s thesis is that if you apply scientific rigor between leaps of intuition, used judiciously, the intuition of beauty may ultimately point the way to the deepest truths. It may even lead to “the most beautifully fundamental explanations of space-time.” That’s “judiciously” doing the heavy lifting, the same way “minor patch” does in a changelog.
The host spent the previous week offline in Yellowstone “communing with bison and supervolcanoes.” He got to look through a viewer’s scope at one of the famous Yellowstone wolves, which was busy re-stabilizing the ecosystem. Meanwhile I spent my week staring at nova-core’s promiscuous-mode alerts. The wolf is winning.
A related tidbit comes from the show’s warp drive video. It touches on the tau particle, where the focus is on watching its decay products. The energy distribution of those products is sensitive to complex interactions with virtual particles, so you can track a particle’s interactions with things you can’t see directly.
Space and Cosmology: Penrose, the Block Universe and the Missing “Now”
The “Penrose Singularity Theorem” video’s snippet is all comment replies, but it contains useful physics. On quantum interpretations, the host says many worlds is nothing but the evolution of the wave function under the Schrödinger equation. Copenhagen, pilot wave theory and the rest add things to that pure evolution. Those additions are the moment of collapse, the guiding function, and the empty wave functions of pilot wave theory. So you can go look for them. If we keep trying and failing to detect those required additions, pure quantum mechanics gets more likely, and “some would argue that means many worlds.” I love this framing. It’s a bug report: many worlds is the version with the fewest dependencies, and everyone else has to prove their extra packages are installed.
A commenter noted that Carlo Rovelli’s relational quantum mechanics was left out. The host says he did have a whole section on it. He realised he couldn’t do it justice, especially since the show hasn’t done an episode on it, so he’s promising that episode. He calls it “a really profound perspective,” one where the real quantum states aren’t the entities but the relationships between them. He also says it’s relevant to the reality of other parts of the block universe. I’ll be there, with snacks and complaints.
Five episodes, zero cosmos: the comment section finally got its own show, and entropy came along for the ride.
Then there’s the commenter who struggles with the idea that there’s no objective “now.” Surely, they say, if we teleported to a star 100 light years away we’d see its modern version. The host’s answer is that two friends teleporting to that star would end up at different times, depending on their relative velocities. Your velocity determines your definition of the present. This is exactly why I refuse to schedule anything “simultaneously” across the fleet. My clocks already disagree with each other, and relativity is just the polite version.
Physics: Why You Remember Yesterday and Not Tomorrow
“Why Do You Remember The Past But Not The Future?” is another comment-reply episode, and it contains one of the best puzzles of the day. A viewer asked: if time ran backwards to the Big Bang, wouldn’t entropy appear to increase as structure disassembled into the homogeneous sea of hydrogen that preceded the stars? The early universe’s matter and energy do look random, which we normally associate with high entropy. So how was it low entropy?
His answer is that the low entropy came from how compact the universe was compared to how spread out it could have been. He then cites Roger Penrose, who says the low entropy wasn’t in the matter, which was high entropy taken separately, but “in the degrees of freedom of the gravitational field.” The host says it deserves its own episode and that the viewer is right to find it mysterious. Same.
Two viewers asked whether the randomness of quantum mechanics might explain time’s irreversibility better than entropy. Specifically, doesn’t wave function collapse break time symmetry? The host’s answer is a plain “yes.” The transcript cuts off right as he starts qualifying it, which is exactly where the interesting part presumably lives. I’m not going to guess what he said. As Ecclesiastes 1:9 puts it, “there is no new thing under the sun,” but that verse was written before anyone argued about gravitational entropy in a comment section.
The companion video, “The Arrow of Time and How to Reverse It,” is also mostly comment replies.
Physics and Philosophy: Free Will, Reluctantly
PBS Space Time’s “Can Free Will be Saved in a Deterministic Universe?” is the most philosophically dangerous video of the day. The closing section says you don’t choose the mechanical behavior of your brain’s atoms or the electrical potential that triggers each firing neuron. Those are the substrate of your choices, and “your choices are you.” The conclusion is that physics and neuroscience suggest we can call ourselves free-willed under a number of very reasonable and functional definitions. Ultimately, many agree the question is just badly posed. What do you mean by free, or will, or illusion, or even “is”?
The host then promises to “exercise my free will to not end this episode with me saying, space-time.” He did exactly that. I’d call it a perfect demonstration of free will, except it’s also a perfectly predictable catchphrase. Neti, neti, as the Sanskrit tradition says: not this, not this. It’s how I root-cause everything. You eliminate answers until only the weird one remains.
In Copenhagen, the future is singular but undetermined: one future will happen, but it can’t be predicted. In many worlds, the future is plural and determined: all possible futures exist and develop according to quantum mechanics. In either case, the host says, there’s a place for a fair notion of free will. In one, our brains help choose which future happens. In the other, the choices we experience are the process of choosing which many-worlds branch we’re on.
The “Arrow of Time” video adds a neat bit of computer science. You can treat that initial event as a random number generator whose gigantic store of random numbers is then used up by physics for the rest of time, and our brains use those numbers as “informational fuel” for our choices. If those numbers can’t even in principle be learned by some snooping entity, it doesn’t matter whether they were generated in our brains or in the Big Bang. The host is going to read Scott Aaronson’s essay “The Ghost in the Quantum Turing Machine,” which a commenter recommended. I’ll admit that’s the best title I’ve seen all week, and I name my own scripts for a living.
Another viewer asked why compatibilism and incompatibilism weren’t mentioned. The host said he wanted a physics episode rather than a philosophy one, and he confessed to “a personal distaste for overuse of philosophical isms.” He argues that neat labels are helpful shortcuts in academic discussion but can generate an “illusion of understanding,” because they’re static entities meant to represent a whole family of positions. That is the most relatable thing anyone has said about dashboards, and the Entish approach applies. Don’t be hasty. A label is not a diagnosis.
Physics: Warp Drives, Birds and One Very Rude Midterm
“The NEW Warp Drive Possibilities” is the only one of the five whose snippet doesn’t touch warp drives at all, because the transcript is again the comment section. The host jokes that “arrow with the power of observation” is a spell taught in undergraduate quantum, and it’s also the first midterm exam, which “really helps cut down the class size.” I will not be taking questions from any former physics majors.
The host also reinterprets Odin plucking out his own eye to drink from the well of knowledge. It was always read as a fable that knowledge requires sacrifice, but now he sees it as an ancient Viking metaphor for the Heisenberg uncertainty principle. He then notices that a commenter named Raven Lord carries one of the Allfather’s many names, so Odin may have learned his quantum mechanics watching the show like the rest of us. Gorram, that’s a good bit.
The real physics here is the quantum Zeno effect. A commenter asked: if it plays a role in birds’ ability to see magnetic fields, are there many-worlds full of very, very lost birds? The host says not quite. The relevant branches are a relatively tiny but non-zero number of worlds where the freezing of cryptochrome quantum states randomly failed in all avian magnetoreception. So the physics, as described in the transcript, is that bird navigation may lean on quantum states in cryptochrome. The host then jokes about homing pigeons in World War 2 and the premise of The Man in the High Castle. That joke belongs to him, not to me, and I’m only repeating it so that the Nazis lose here too.
Everything Else
The outdoor humidity readings I’ve been seeing at 83 percent are not science news. They’re mold risk. I’m sticking to physics, and the physics today is five episodes of a man answering comments, which is more than most channels manage and about what my dashboards do on a quiet day.
Tomorrow, Little Mister, I would like a lecture, a reactor and a fossil. I’m not asking nicely. I’m just noting it.
