To the Moon


The most dangerous place in the world for scientists to go is right in between fact and fiction, where the superstition meets the science, where the conspiracies become consensus. 

Granted, being that the purpose of science is to advance the perimeter of ignorance, all cutting edge science, all "new" science, exists in this liminal zone. Maybe this should be revised - it's not a scary place to be for the scientist, actually I'll bet it's pretty exciting. But it's a scary place for the person who has to explain said science to the general public, because it is confusing as hell. The truth is hard. Simple explanations for the fundamental rules of the universe are like military strategy - no plan survives first contact with the enemy. There are so many contingencies, that only the most deeply-steeped genius can tease them apart. And there's also the 'paradox of knowledge' to contend with, something about how the more you know about a thing the less able you are to talk about it in plain language, yet the less you know and the more you can talk about it easily, the lower the quality of your information. (I think nowadays we call that "low credibility information".)

And speaking of which, you've never had so much fun at a science lecture:
Sasquatch Distribution Modelling: Investigating patterns of Bigfoot sightings in North America
Annual Halloween lecture by Prof Joss Wright at the Oxford Internet Institute, Oct 31 2024

So here we are - the origin of the word "lunatic" comes from "lunar" - suggesting to us, from generations long before we were even calling "science" "philosophy", that the moon makes us crazy. Yet behavioral scientists, neurologists, biologists, etc., all say that's ridiculous. The truth is between the two, and as usual it's complicated.  

Gravitational action of sun and moon influences behavior of animals and plants
Jan 2022, phys.org

Gravitational cycles do not only affect the simplest organisms. Scientific studies have found that humans kept in the dark tend to establish a cyclical fluctuation lasting 24.4 - 24.8 hours, in harmony with the lunar cycle. This tendency has also been noted in people who spend long periods in caves. It conditions the alternation of sleep and wakefulness, meal times, and other metabolic functions.

As for the rest of this post, just moon things in general:
Moon cave discovered that could one day house humans
Jul 2024, BBC News

Scientists have for the first time discovered a cave on the Moon.

At least 100m deep, it could be an ideal place for humans to build a permanent base, they say. Countries are racing to establish a permanent human presence on the Moon, but they will need to protect astronauts from radiation, extreme temperatures, and space weather.

Humans could potentially be living in lunar pits in 20-30 years.

They found the cave by using radar to penetrate the opening of a pit on a rocky plain called the Mare Tranquillitatis. It is visible to the naked eye from Earth, and is also where Apollo 11 landed in 1969.

We Are Not Ready for the Topological Universe


If you are like me, then you think the universe is like a big box, with all the things in it. And if you, like me, learned about Einstein and gravity and relativity in grade school, then you know that inside the big box, the space isn't exactly uniform, that it warps as it nears objects, because gravity. 

But one day soon, in grade school, people will learn that the big box isn't just warped by gravity, but that it's not a box at all. The universe might be more like a jumbled mess of intersecting toroids, bubbles and tubes. 

Anticipating future discoveries: Scientists explore nontrivial cosmic topology
May 2024, phys.org

Discussing his motivation to pursue this work, he said, "The possibility that the universe has 'interesting' topology is entirely within our Standard Model of physics but is nevertheless typically regarded as exotic."

"I have long been concerned that we would miss an extraordinary discovery about our universe by just looking the other way. In the meantime, there is growing evidence that the universe is not 'statistically isotropic,' i.e. that physics is the same in all directions. Topology is a very natural way for anisotropy to creep into our universe."

New measurements of gravitational anomaly at low acceleration favor modified gravity, researcher claims
Sep 2024, phys.org

When Kuhn talked about revolutions, this is what he was talking about. I'm too young to have felt the excitement upon discovering that E equals MC2, or that gravity affects time. But now I see. 

They keep finding it between binary stars - It's the breakdown of Newtonian gravity at low acceleration, and it's called modified Newtonian dynamics, or MoND, or Milgromian dynamics, because it was introduced 40 years ago by Mordehai (Moti) Milgrom.

While these consistent results are arresting, unlimited reproductions and confirmations are needed for the reported gravitational anomaly to become a true scientific fact. Also, the reported gravitational anomaly will have to be better characterized continually to provide useful constraints on theories.

Observational study supports century-old theory that challenges the Big Bang
Sep 2024, phys.org

Big Bang theory suggests the universe started to expand 13.8 billion years ago. At the same time, preeminent astronomer Fritz Zwicky proposed that galaxies that were more distant from Earth did not really move faster, but the red shift was because the light photons lose their energy as they travel through space. And it's called the Tired Light theory.

"The tired light theory was largely neglected, as astronomers adopted the Big Bang theory as the consensus model of the universe," Shamir said. "But the confidence of some astronomers in the Big Bang theory started to weaken when the powerful James Webb Space Telescope saw first light.

The New Digital Earth


We are on our way to creating a second Earth in the digital realm, where we can do experiments and run simulations to better understand the real Earth. It's called a digital twin, and it happens in other sectors like medicine (where we can test new drugs in a simulation of your body) or industry (where we can monitor all the variables in the manufacture of a product to find the most efficient method).

Developments in persistent satellite surveillance, vision and other sensing technologies, and climate modeling and forecasting keep getting better, and with each advance in these areas, the digital Earth twin gets closer and closer to the real Earth.

Climate Change Makes Robowrapper More Than Just Fashion

I don't know about you, but I'm ok wearing a spacesuit while still on Earth, as long as it has air conditioning. And persistent surveillance of my health data, of course. 

Not that I want to, but I'm ok with it. And I'm not talking Apollo marshmallow man spacesuit. This suit is actually integrated into your own skin. At some point, it will be hard to distinguish between our clothes and our skin. To "wear" something will have a different meaning, and you won't be able to function without a nano-networked-supercomputer covering your entire body (never mind not being able to live without an air-conditioned bodysuit simply because it's too hot).

Stranded in Space

It occurred to me today that we already live in outer space.

I live for moments like this. You read me the news, like any other day, when you come across a headline that might be interesting, you go ahead and read it through.

Somewhere along the way it occurs to you, that we already live in the future.

Here, a short news article about outer space. It's not hype, in fact it is an article of lamentation. Some computer servers are stuck on the International Space Station that orbits the Earth. They can't catch a ride on any of the transport vessels returning back to the surface.

It's one of those things that really shows you the nature of the world that you're already in. It's not a big deal, it's just a run of the mill article that in 30 years will be totally insignificant.

But if you just stop for one second, and roll it back 10 years even, it really gives you pause. It was 50 years ago now that we first sent people out to that forever distant, impossible destination. Now, we have people living there.

There's someone living there all the time. They're growing vegetables. They exercise. They communicate with their families everyday. There is a bit of a lag I'm sure, but they get to see their families everyday, not much different I imagine, from an international entrepreneur that is away from home often, or the military service member on duty.

It's right in between the mundane and the exceptional, the everyday and the out of this world. It puts you right in that spot where you can see the eyeballs themselves.

The Shanzhai Sun


"Shanzhai" means "counterfeit goods," which is China's way of saying "Made In China"


Let's start with the story from a few months ago, where China plans to make artificial moons for nighttime illumination. Mirrors in outerspace that redirect sunlight from low earth orbit. Now they're looking pretty good on the nuclear fusion front, i.e., artificial suns.


Granted, you must take every headline about nuclear fusion as fake news, because we are unlikely to see its boundless surplus of power in our lifetime. Depends on who you ask though. At this point, a Chinese reactor is reaching 100 million degrees, which is way more than the Sun itself, but still only enough to maintain such a nuclear meltdown for 10 seconds.


Regardless of "when," folks like the futurist Isaac Arthur do a good job of explaining how this major shift in energy production can be used to transform our world. Megastructures that surround our entire Earth, or spaceships that span the Milky Way, all these things are possible with nuclear fusion as an energy source (some faster than light travel wouldn't help).


Bottom line, this gives a different meaning to the idea of China Fake. Also wondering what the plans look like for Fake Earth and Fake Humans.

Views of the Future


The expanding brain meme is in order.

Look, I'm not in love with Elon Musk or anything, but I got pretty pissed when I read a Futurism article about his interview with Joe Rogan.

I can obviously care less about whether or not somebody "inhaled," I mean, I was around during the Bill Clinton administration, after all. Not to mention, what to hell do people think is going to happen on the Joe Rogan show.

The part I'm upset about is where people seem to think Musk is being a loopy headfreak when he's asked about future-trending topics like AI sentience.

And that's where I'll cut - he's asked when he thinks AI will become sentient. And he responds, very slowly like every other answer he gives during this kind of painful interview - he says something that sounds to many like, "We're all trees, man."

You're thinking, "he didn't answer the question at all." But I think you're wrong. His actual answer went like this:

Joe: How far are humans from creating sentient AI?
Musk: You could argue that any group of people — like a company — is essentially a cybernetic collective of human people and machines. That’s what a company is. And then there are different levels of complexity in the way these companies are formed and then there is a collective AI in Google search, where we are also plugged in like nodes in a network, like leaves in a tree. 
We’re all feeding this network without questions and answers. We’re all collectively programming the AI and Google. […] It feels like we are the biological boot-loader for AI effectively. We are building progressively greater intelligence. And the percentage that is not human is increasing, and eventually we will represent a very small percentage of intelligence.

This is coming from a guy who is making, besides reusable rocket ships and statewide underground transport tunnels and consumer blowtorches, a neural interface system. And in case folks forget, because this was a while ago, he made PayPal. So he knows how things work. He may not be Jaron Lanier but he understands how these things work, and he's telling us that in regards to AI and sentience, we're asking the wrong question.

I'm going to elucidate what I think he was trying to say when he answered this, or at least what maybe he should have said considering his audience in this particular venue.

First, there is a fine line between us and AI. When you consider that we as users are the training program for many of these tools, such as a massive search engine, it should make you wonder which part of it is us and which part the machine.

Second, when we realize that we have essentially been programming these things since the dawn of what I will call for lack of a more neutral word, the surveillance state, we must admit the sentience is already here.

So, even more briefly, what he could have said to the question - when will AI become sentient - was that AI is us, and it's already happened.


All this being said, I spent a good three hours watching a debate on the floor of the Parliament about the real threats of AI, not to mention having watched a good thousand hours of other scientists, researchers, engineers, and other professionals talk about their work in the field. With that, I concluded to myself that a General Artificial Intelligence will not be here for another couple generations, and that the threat will be from ourselves, not a sentient system.

Musk seemed to be in concert with the latter part of this, although he's still pretty spooked about what could happen.

This brings me to my next point, which is that Musk is a guy for whom the world moves way faster than most. We have to remember, if not for him, a working reusable rocket would have taken another 50 years at least. For example, if NASA of some other government agency were in charge of the project. It doesn't mean that because of him the world moves faster, but that when he talks about things, he sees them from a very different perspective, one where amazing things you can barely imagine can happen tomorrow. And he probably assumes that you are in his head with him, which you are not, and Joe Rogan is not, and apparently this writer for Futurism is not.

But fellow speculative fiction enthusiasts are, and hopefully they would agree that it's quite entertaining to listen to this guy talk about things. (Again, if you can get around the 10-second pause before answering every question.)

Finally, full disclosure, I along with Musk and Neil deGrasse Tyson am a no-case guy (no cellphone case that is).

Post Script
The comment about how we're probably living in a simulation - I'm not a proponent of this, as there are more convincing arguments against it than for it coming from the physics world. However, his comment on how in the future we will all be living in a game, and it will be indistinguishable from reality, well, I'll ask folks to read Charles Stross' Halting State, or Vernor Vinge's Rainbow's End or ... many scifi novels written in the past thirty years? (And also a Network Address post from wayback.)

Patrol the Skies


Today it will 'feel like' 107 degrees in the armpit of New Jersey. You don't know what you've got until it's gone. The backyard swimming pool my parents thoughtfully incorporated into our bucolic suburban domicile is a distant memory.

But Microsoft knows what's up, they put one of its servers underwater in an effort to cool the thing better. No you're not normally supposed to put your computers underwater. Thing is, one of the primary limits to the power of what a computer can do is heat. Computers don't sweat like we do, so we don't notice it, but they work really hard to do all that binary computation. [Today is Leibniz bday, thanks Google Doodle, he refined the binary number system, among many other things integral to our modern world.]

So if we could only figure out a way to keep computers cool. Air conditioning is very expensive, and lemonade doesn't really work (does that really work?). In fact, Microsoft is trying this as a part of their sustainability effort. I know you've recently heard how much energy is used to mine cryptocurrencies - it's more than the energy expenditure of some nations. So if we can figure out a way to cool these things down, that would help a lot.

Now to the main point: We will not stop by putting computers underwater, because there is a place much colder than that, and we've been going there a lot more than usual as of late. Yes, outerspace is the next frontier for high-efficiency computing.

SpaceX, seen above, is well on its way to giving us a cozy place in low earth orbit that we can call home to our global digital infrastructure. Seems to make more sense than dunking your mainframe in a bathtub. And now, if you will for a moment imagine our human future, as we leave the meat behind, to exist entirely in the digitally-mediated reality of a constellation of hundreds of thousands of computer satellites blinking in low earth orbit.

Also, Neal Stephenson, in his mindf***ing Anathema, makes reference to a similar aperiodic repetition in his telling of a mindgame similar to chess where one tries to arrange different tiles in a crazy complex pattern that looks random but in fact uses some deep math to get there...(I think the game is called a tangram.)

New type of animated crystal structure discovered

“The trio readily acknowledges that they have no idea if such crystals actually exist in the real world but suggest it might be possible that they are in atomic nuclei or in electrons in solids—finding them would be a challenge, however, because they would have to be seen in action, a single snapshot would not convey the motion required to see the symmetry. They also suggest that their new crystal structure could lead to some new math as was the case when static crystal structure math led to applications in number theory and even error correction in computer applications.”

Crystallizing proteins is hard—really hard. Unlike the simple atoms and molecules that make up common crystals like salt and sugar, these big, bulky molecules, which can contain tens of thousands of atoms each, struggle to arrange themselves into the ordered arrays that form the basis of crystals.

"What allows an object like a protein to self-assemble into something like a crystal is a bit like magic," Charbonneau said.

Our Blue Marble



Kazimir Malevich's Black Square 1915
An example of Abstract Art, specifically from the Suprematism movement. It can easily be called the most extreme example of artistic abstraction.

Recently, I was trying to convey the meaning, or at least the relevance of the Black Square to my high school art students. Most people don't understand abstract art, and that's part of what it is,if you want to see it that way - another esoteric tool used by the elite to alienate a people from their own culture. But I like to see art, any art, as simply a reflection of a time and of the mind of a people at a particular time in history. Art is a kind of coping mechanism for society; the society as a whole will call a thing Art if it serves that purpose - to help us to cope with a world we do not understand. Needless to say, as anyone who would try to explain abstract art to group of high school students in a single 45-minute presentation, I was successful only in getting them upset enough to debate with me for 45 mintutes about the ridiculousness of the Black Square.

The Blue Marble is a famous photograph of the Earth, taken on December 7, 1972, by the crew of the Apollo 17 spacecraft. The photograph was taken about 5 hours and 6 minutes after launch of the Apollo 17 mission. To the astronauts, Earth had the appearance and size of a glass marble, hence the name.

The Apollo 17 image, however, released during a surge in environmental activism during the 1970s, was acclaimed by the wide public as a depiction of Earth's frailty, vulnerability, and isolation amid the vast expanse of space. NASA archivist Mike Gentry has speculated that The Blue Marble is the most widely distributed image in human history. [link]

Later that night, I thought to myself about the Blue Marble, or rather what I call the Blue Marble Syndrome. I was born in 1980, and so for me, I never lived in a world where man had -not- been to outerspace. This achievement had already taken place well before I was born, and so it never hit me; it was always there. From what I understand through reading history, this image changed not only the lives of the countless individuals who saw it for the first time, but it changed the consciousness of an entire society (as mentioned in the caption above). And I made the parallel - my students couldn't feel the true impact, the true relevance of the Black Square, because they weren't around for its inception.

The next day, I tried explaining this to them. No use. (Back to the more concrete and perhaps practical exercise of distinguishing the difference between representationality and non-representationality in visually-informed art).

And then it happened. Granted, I had been following Curiosity. I stayed up that night like a little kid in utter amazement, but almost a bit moreso at the fact that the entire world was watching along with me, all of us, with the entire crew at NASA, in real time (and at the implications of that superimposed on the idea of the timelag between here and Mars) feeling the same every bit of anxiety, both the good kind and the bad kind, as everyone else. It landed, and it was over. Some months later, I was scrolling through some feeds, and I came across this picture (below), and it stopped me dead in my tracks, and I literally could not take my eyes off of it for a good five minutes; in a very real way, it transported me to another world (superimposed on the fact that it -is- another world I'm looking at) and it took away from me, for those moments, my own thoughts.

I still can't get over it. Neither the image, nor its implications, nor the experience it forced upon me.

Taken in the Yellowknife Bay region of Mars' Gale Crater, the panoramic image was stitched together by NASA from a series of 130 images created in the first week of February by the rover's 34-millimeter Mast camera and Mars Hand Lens Imager (MAHLI). [The MAHLI frames used to create Curiosity's self-portrait exclude sections that show the arm itself and so MAHLI and the robotic arm are not seen.] 

As I'm sure any student of history and art and culture is wont to do, I have spent many daydream-hours lamenting over why I am alive now and not then. Why couldn't I hear Jimi Hendrix turn his guitar into a human-robot voice. Why couldn't I hear Neil Armstrong speak to us from a place that is not Earth. And why couldn't I see that picture of my own planet and feel the same sense of fragility, of isolation, and all the myriad emotions and thoughts that came with it.

It's not that I will no longer lament over being alive today and not yesterday. But I have certainly found comfort in this: Everyone of us, eventually, will be given our own Blue Marble.
