- In the 1970s NASA published an extensive book on urban planning in space.

One day humanity will again step foot on other worlds. When that day comes we will need to build new cities in these places. Where we go, our cities go. The urban form follows us like a civilizational shadow.
In order to house our post-terrestrial bound culture, we'll first need to layout the new order of our settlements. There are three prime candidate planets and places in space that may be the first to house our founding space pioneers.
These are the Moon, Mars, and orbital habitats around Earth.
Major governmental space agencies, engineering firms and even urban planning groups have already seriously considered the prospect of space colonization.
In 1977 NASA published "Space Settlements: A Design Study." This extensive 155-page book essentially contains a city planning policy guide on the future of cities and urban planning in space. The book focuses exclusively on orbital civilian habitats – the type that would revolve and settle in Lagrange Points around Earth.
"Space Settlements" covers everything it can think of, from the psychology of its inhabitants, rocket landing areas, and zoning land-use to the barebones of oxygen production. Even with such depth the book still covers only a small portion of the challenges facing space colonization.
The sheer scale of genius needed for this feat will keep us busy down here for years.
Yet, urbanists would be happy to hear that the plan advocates for communities that are walkable, transit-oriented, dense and inclusive. This list checks off a fair bit of principles modern urban planners abide by.
The book's authors even took the time to think about the notion of the first extraterrestrial pioneers' budding culture:
The first extraterrestrial communities may not be purely American if the United States is no longer a major world power or a major technological center by the time the first extraterrestrial community is established. If the United States remains a major world power, many nations including nonwestern nations and African nations could be highly technological and want to participate, so that the first extraterrestrial community may be international.
The present technological nations are not necessarily advantaged, because the technology they possess is "Earth-bound" in addition to being culture-bound. They may have first to unlearn the forms, the assumptions and the habits of the Earth-bound technology before learning the new forms and assumptions of technology useful in extraterrestrial communities.
Moon culture evolution, confirmed. The thought of new cultures developing in the newly forged lunar cities and floating metropolis colonies would be a testament to our accomplishment.
Building a city on the Moon

What would it take to build a full scale city on the moon? Skidmore, Owings & Merrill recently threw their hat in the proverbial moon ring.
In partnership with the European Space Agency (ESA) and the Massachusetts Institute of Technology (MIT), SOM presented a conceptual design for their "Moon Village." In a press statement, Design Partner Colin Koop talked about the new challenges needed for architectural design in space.
"The project presents a completely new challenge for the field of architectural design. The Moon Village must be able to sustain human life in an otherwise uninhabitable setting. We have to consider problems that no one would think about on Earth, like radiation protection, pressure differentials, and how to provide breathable air."
Masterplanning, designing and engineering the imagined settlement, SOM imagines are cross-disciplinary collaboration and an entirely new way to approach the space industry's most complex problems.
- The Moon Village is imagined on the edge rim of the Shackleton Crater near the South Pole.
- This area was selected because it receives near continuous daylight throughout the whole lunar year.
- Overall development plans were envisioned in three distinct phases to set up infrastructure, resources and habitable structures.
The Moon Village would sustain its energy from direct sunlight and set up food generation and life-sustaining elements through in situ resource utilization by tapping into the Moon's natural resources. Water extracted from the depressions near the South Pole would create breathable air and rocket propellants to support the burgeoning industry in the town. By being near the South Pole, the town would have direct access to the crater's water-ice deposits.
As for habitats for lunarites to live in, there would be individual pressurized modules which are inflatable, giving residents the flexibility to increase their living space when needed.
Most buildings would be three to four story structures that would serve as a combined workspace, living quarter and have the necessary environmental and life support systems integrated into each one.
The Moon Village was created for the ESA's reflection of future exploration beyond 2050 in partnership with NASA's strategic plan to "extend human presence deeper into space and to the Moon for sustainable long term exploration and utilization."
A pioneer Moon Village could set in stone the first opportunity to permanently inhabit the moon, spur research and explorations and serve as a gateway to the rest of the solar system and beyond.
Designing cities in Space Colonies

Such ring habitats have been a common sight in science fiction for years, from Halo's massive ring worlds to Neuromancer's Tessier-Ashpool floating Freeside. But physicists have known for quite some time that they're actually possible to build. When space becomes more accessible, these would be the first contenders for habitation.
In NASA's "Space Settlements" study, researchers dedicated a few chapters on basic comprehensive plans, which is a deep dive into how much space would be needed for residential housing, schools and other land uses combined with transportation and other infrastructure. As for transportation, the book again goes into detail:
"Because of the relatively high population density (15,000 people/km2) in the community, most of the circulation is pedestrian, with one major mass transport system (a moving sidewalk, monorail, and minibus) connecting different residential areas in the same colony."
These floating cylinders with artificial gravity would survive by creating from the natural resources of outer space. Again in the 1970s Princeton physicist Gerald K O'Neill laid out compelling studies where he envisioned 100,000-person colonies, stationed at what is known as the fifth Lagrangian libration point (L5) in the moon's orbit.
"It is orthodox to believe that Earth is the only practical habitat for Man, but we can build new habitats far more comfortable, productive and attractive than is most of Earth," he wrote in Physics Today in 1974.
He was interested in building alternative human habitats that were both beyond Earth and beyond a planetary body. Out of this was conceived the idea of a giant rotating spaceship, which could support a biosphere and house up to 10 million people.
Planning the first cities on Mars

In 2017, an MIT team developed a design for a settlement that won the Mars City Design competition. MIT's winning urban plan, titled Redwood forest, proposed to create domes or tree habitats that would house up to 50 people each. The domes provided residents with open public spaces containing vegetation and water, which would be harvested from deep in the Martian northern plains.
The tree habitats would be connected on top of a network of tunnels, or roots, providing transportation and access to both public and private spaces between other inhabitants of this proposed 10,000 strong community. Advanced technology such as artificial light inside these pods could strongly mimic the sight of natural sunlight.
MIT postdoc Valentina Sumini who led the interdisciplinary team, described the project's design fundamentals and elaborated on the project's poetic forest metaphor:
"On Mars, our city will physically and functionally mimic a forest, using local Martian resources such as ice and water, regolith (or soil), and sun to support life. Designing a forest also symbolizes the potential for outward growth as nature spreads across the Martian landscape. Each tree habitat incorporates a branching structural system and an inflated membrane enclosure, anchored by tunneling roots.
The design of a habitat can be generated using a computational form-finding and structural optimization workflow developed by the team. The design workflow is parametric, which means that each habitat is unique and contributes to a diverse forest of urban spaces."
The team aims to build a comfortable environment and architecture that focuses on the fundamental and critical aspect of sustainability, a baseline component needed for any Mars or offworld city.
On the entirety of the system, System Design Management Fellow George Lordos summed up the functionality by explaining the holistic and connected system they imagined.
"Every tree habitat in Redwood Forest will collect energy from the sun and use it to process and transport the water throughout the tree, and every tree is designed as a water-rich environment. Water fills the soft cells inside the dome providing protection from radiation, helps manage heat loads, and supplies hydroponic farms for growing fish and greens. Solar panels produce energy to split the stored water for the production of rocket fuel, oxygen, and for charging hydrogen fuel cells, which are necessary to power long-range vehicles as well as provide backup energy storage in case of dust storms."

U.S. Navy ships
The U.S. Navy controls patents for some futuristic and outlandish technologies, some of which, dubbed "the UFO patents," came to life recently. Of particular note are inventions by the somewhat mysterious Dr. Salvatore Cezar Pais, whose tech claims to be able to "engineer reality." His slate of highly-ambitious, borderline sci-fi designs meant for use by the U.S. government range from gravitational wave generators and compact fusion reactors to next-gen hybrid aerospace-underwater crafts with revolutionary propulsion systems, and beyond.
Of course, the existence of patents does not mean these technologies have actually been created, but there is evidence that some demonstrations of operability have been successfully carried out. As investigated and reported by The War Zone, a possible reason why some of the patents may have been taken on by the Navy is that the Chinese military may also be developing similar advanced gadgets.
Among Dr. Pais's patents are designs, approved in 2018, for an aerospace-underwater craft of incredible speed and maneuverability. This cone-shaped vehicle can potentially fly just as well anywhere it may be, whether air, water or space, without leaving any heat signatures. It can achieve this by creating a quantum vacuum around itself with a very dense polarized energy field. This vacuum would allow it to repel any molecule the craft comes in contact with, no matter the medium. Manipulating "quantum field fluctuations in the local vacuum energy state," would help reduce the craft's inertia. The polarized vacuum would dramatically decrease any elemental resistance and lead to "extreme speeds," claims the paper.
Not only that, if the vacuum-creating technology can be engineered, we'd also be able to "engineer the fabric of our reality at the most fundamental level," states the patent. This would lead to major advancements in aerospace propulsion and generating power. Not to mention other reality-changing outcomes that come to mind.
Among Pais's other patents are inventions that stem from similar thinking, outlining pieces of technology necessary to make his creations come to fruition. His paper presented in 2019, titled "Room Temperature Superconducting System for Use on a Hybrid Aerospace Undersea Craft," proposes a system that can achieve superconductivity at room temperatures. This would become "a highly disruptive technology, capable of a total paradigm change in Science and Technology," conveys Pais.

Another invention devised by Pais is an electromagnetic field generator that could generate "an impenetrable defensive shield to sea and land as well as space-based military and civilian assets." This shield could protect from threats like anti-ship ballistic missiles, cruise missiles that evade radar, coronal mass ejections, military satellites, and even asteroids.
Dr. Pais's ideas center around the phenomenon he dubbed "The Pais Effect". He referred to it in his writings as the "controlled motion of electrically charged matter (from solid to plasma) via accelerated spin and/or accelerated vibration under rapid (yet smooth) acceleration-deceleration-acceleration transients." In less jargon-heavy terms, Pais claims to have figured out how to spin electromagnetic fields in order to contain a fusion reaction – an accomplishment that would lead to a tremendous change in power consumption and an abundance of energy.
According to his bio in a recently published paper on a new Plasma Compression Fusion Device, which could transform energy production, Dr. Pais is a mechanical and aerospace engineer working at the Naval Air Warfare Center Aircraft Division (NAWCAD), which is headquartered in Patuxent River, Maryland. Holding a Ph.D. from Case Western Reserve University in Cleveland, Ohio, Pais was a NASA Research Fellow and worked with Northrop Grumman Aerospace Systems. His current Department of Defense work involves his "advanced knowledge of theory, analysis, and modern experimental and computational methods in aerodynamics, along with an understanding of air-vehicle and missile design, especially in the domain of hypersonic power plant and vehicle design." He also has expert knowledge of electrooptics, emerging quantum technologies (laser power generation in particular), high-energy electromagnetic field generation, and the "breakthrough field of room temperature superconductivity, as related to advanced field propulsion."
Suffice it to say, with such a list of research credentials that would make Nikola Tesla proud, Dr. Pais seems well-positioned to carry out groundbreaking work.

The patents won't necessarily lead to these technologies ever seeing the light of day. The research has its share of detractors and nonbelievers among other scientists, who think the amount of energy required for the fields described by Pais and his ideas on electromagnetic propulsions are well beyond the scope of current tech and are nearly impossible. Yet investigators at The War Zone found comments from Navy officials that indicate the inventions are being looked at seriously enough, and some tests are taking place.

If brute force doesn't work, then look into the peculiarities of nothingness. This may sound like a Zen koan, but it's actually the strategy that particle physicists are using to find physics beyond the Standard Model, the current registry of all known particles and their interactions. Instead of the usual colliding experiments that smash particles against one another, exciting new results indicate that new vistas into exotic kinds of matter may be glimpsed by carefully measuring the properties of the quantum vacuum. There's a lot to unpack here, so let's go piecemeal.
It is fitting that the first question asked in Western philosophy concerned the material composition of the world. Writing around 350 BCE, Aristotle credited Thales of Miletus (circa 600 BCE) with the honor of being the first Western philosopher when he asked the question, "What is the world made of?" What modern high energy physicists do, albeit with very different methodology and equipment, is to follow along the same philosophical tradition of trying to answer this question, assuming that there are indivisible bricks of matter called elementary particles.
Deficits in the Standard Model
Jumping thousands of years of spectacular discoveries, we now have a very neat understanding of the material composition of the world at the subatomic level: a total of 12 particles and the Higgs boson. The 12 particles of matter are divided into two groups, six leptons and six quarks. The six quarks comprise all particles that interact via the strong nuclear force, like protons and neutrons. The leptons include the familiar electron and its two heavier cousins, the muon and the tau. The muon is the star of the new experiments.
For all its glory, the Standard Model described above is incomplete. The goal of fundamental physics is to answer the most questions with the least number of assumptions. As it stands, the values of the masses of all particles are parameters that we measure in the laboratory, related to how strongly they interact with the Higgs. We don't know why some interact much stronger than others (and, as a consequence, have larger masses), why there is a prevalence of matter over antimatter, or why the universe seems to be dominated by dark matter — a kind of matter we know nothing about, apart from the fact that it's not part of the recipe included in the Standard Model. We know dark matter has mass since its gravitational effects are felt in familiar matter, the matter that makes up galaxies and stars. But we don't know what it is.
Whatever happens, new science will be learned.
Physicists had hoped that the powerful Large Hadron Collider in Switzerland would shed light on the nature of dark matter, but nothing has come up there or in many direct searches, where detectors were mounted to collect dark matter that presumably would rain down from the skies and hit particles of ordinary matter.
Could muons fill in the gaps?
Enter the muons. The hope that these particles can help solve the shortcomings of the Standard Model has two parts to it. The first is that every particle, like a muon, that has an electric charge can be pictured simplistically as a spinning sphere. Spinning spheres and disks of charge create a magnetic field perpendicular to the direction of the spin. Picture the muon as a tiny spinning top. If it's rotating counterclockwise, its magnetic field would point vertically up. (Grab a glass of water with your right hand and turn it counterclockwise. Your thumb will be pointing up, the direction of the magnetic field.) The spinning muons will be placed into a doughnut-shaped tunnel and forced to go around and around. The tunnel will have its own magnetic field that will interact with the tiny magnetic field of the muons. As the muons circle the doughnut, they will wobble about, just like spinning-tops wobble on the ground due to their interaction with Earth's gravity. The amount of wobbling depends on the magnetic properties of the muon which, in turn, depend on what's going on with the muon in space.
This is where the second idea comes in, the quantum vacuum. In physics, there is no empty space. The so-called vacuum is actually a bubbling soup of particles that appear and disappear in fractions of a second. Everything fluctuates, as encapsulated in Heisenberg's Uncertainty Principle. Energy fluctuates too, what we call zero-point energy. Since energy and mass are interconvertible (E=mc2, remember?), these tiny fluctuations of energy can be momentarily converted into particles that pop out and back into the busy nothingness of the quantum vacuum. Every particle of matter is cloaked with these particles emerging from vacuum fluctuations. Thus, a muon is not only a muon, but a muon dressed with these extra fleeting bits of stuff. That being the case, these extra particles affect a muon's magnetic field, and thus, its wobbling properties.
About 20 years ago, physicists at the Brookhaven National Laboratory detected anomalies in the muon's magnetic properties, larger than what theory predicted. This would mean that the quantum vacuum produces particles not accounted for by the Standard Model: new physics! Fast forward to 2017, and the experiment, at four times higher sensitivity, was repeated at the Fermi National Laboratory, where yours truly was a postdoctoral fellow a while back. The first results of the Muon g-2 experiment were unveiled on 7-April-2021 and not only confirmed the existence of a magnetic moment anomaly but greatly amplified it.
To most people, the official results, published recently, don't seem so exciting: a "tension between theory and experiment of 4.2 standard deviations." The gold standard for a new discovery in particle physics is a 5-sigma variation, or one part in 3.5 million. (That is, running the experiment 3.5 million times and only observing the anomaly once.) However, that's enough for plenty of excitement in the particle physics community, given the remarkable precision of the experimental measurements.
A time for excitement?
Now, results must be reanalyzed very carefully to make sure that (1) there are no hidden experimental errors; and (2) the theoretical calculations are not off. There will be a frenzy of calculations and papers in the coming months, all trying to make sense of the results, both on the experimental and theoretical fronts. And this is exactly how it should be. Science is a community-based effort, and the work of many compete with and complete each other.
Whatever happens, new science will be learned, even if less exciting than new particles. Or maybe, new particles have been there all along, blipping in and out of existence from the quantum vacuum, waiting to be pulled out of this busy nothingness by our tenacious efforts to find out what the world is made of.
Think of the nicest person you know. The person who would fit into any group configuration, who no one can dislike, or who makes a room warmer and happier just by being there.
What makes them this way? Why are they so amiable, likeable, or good-natured? What is it, you think, that makes a person good company?
There are really only two things that make someone likable.
This is the kind of advice that comes from one of history's most famously good-natured thinkers: Benjamin Franklin. His essay "On Conversation" is full of practical, surprisingly modern tips about how to be a nice person.
Franklin begins by arguing that there are really only two things that make someone likable. First, they have to be genuinely interested in what others say. Second, they have to be willing "to overlook or excuse Foibles." In other words, being good company means listening to people and ignoring their faults. Being witty, well-read, intelligent, or incredibly handsome can all make a good impression, but they're nothing without these two simple rules.
The sort of person nobody likes
From here, Franklin goes on to give a list of the common errors people tend to make while in company. These are the things people do that makes us dislike them. We might even find, with a sinking feeling in our stomach, that we do some of these ourselves.
1) Talking too much and becoming a "chaos of noise and nonsense." These people invariably talk about themselves, but even if "they speak beautifully," it's still ultimately more a soliloquy than a real conversation. Franklin mentions how funny it can be to see these kinds of people come together. They "neither hear nor care what the other says; but both talk on at any rate, and never fail to part highly disgusted with each other."
2) Asking too many questions. Interrogators are those people who have an "impertinent Inquisitiveness… of ten thousand questions," and it can feel like you're caught between a psychoanalyst and a lawyer. In itself, this might not be a bad thing, but Franklin notes it's usually just from a sense of nosiness and gossip. The questions are only designed to "discover secrets…and expose the mistakes of others."
3) Storytelling. You know those people who always have a scripted story they tell at every single gathering? Utterly painful. They'll either be entirely oblivious to how little others care for their story, or they'll be aware and carry on regardless. Franklin notes, "Old Folks are most subject to this Error," which we might think is perhaps harsh, or comically honest, depending on our age.
4) Debating. Some people are always itching for a fight or debate. The "Wrangling and Disputing" types inevitably make everyone else feel like they need to watch what they say. If you give even the lightest or most modest opinion on something, "you throw them into Rage and Passion." For them, the conversation is a boxing fight, and words are punches to be thrown.
5) Misjudging. Ribbing or mocking someone should be a careful business. We must never mock "Misfortunes, Defects, or Deformities of any kind", and should always be 100% sure we won't upset anyone. If there's any doubt about how a "joke" will be taken, don't say it. Offense is easily taken and hard to forget.
On practical philosophy
Franklin's essay is a trove of great advice, and this article only touches on the major themes. It really is worth your time to read it in its entirety. As you do, it's hard not to smile along or to think, "Yes! I've been in that situation." Though the world has changed dramatically in the 300 years since Franklin's essay, much is exactly the same. Basic etiquette doesn't change.
If there's only one thing to take away from Franklin's essay, it comes at the end, where he revises his simple recipe for being nice:
"Be ever ready to hear what others say… and do not censure others, nor expose their Failings, but kindly excuse or hide them"
So, all it takes to be good company is to listen and accept someone for who they are.
Philosophy doesn't always have to be about huge questions of truth, beauty, morality, art, or meaning. Sometimes it can teach us simply how to not be a jerk.
