Welcome! If you're interested in particular subjects, may I recommend a Collection or few to follow? This is what I post:

+ The Ogg-Nat War -- This isn't your father's Martian Revolution. A worldbuilding exercise on the premise of genetically augmented Martians and Selenians versus "natural" Terrans. Regular postings. 

+ Kerbal Space Program -- My favorite video game, which I credit with rekindling my love for space and bringing my remaining brain cells back to life. Deprecated in favor of Space Gaming.

+ *Space Gaming* -- a catchall for all the space video games I play. Kerbal Space Program is at the top of that list, but other games with a space theme will make an appearance as I toy with them. Regular postings.

+ Space Science & Exploration -- Spacecraft, astronomy, planetary science, astronauts, and other related subjects. Regular postings.

+ Misc. Science & Technology -- Science/tech not directly related to space, more or less. Regular postings.

+ Such A Geek -- Also a nerd and a dweeb. Sometimes a dork, too. So anything from mathematics to comic books will wind up here. Regular postings.

+ Technology & Its Abuses -- Even with a broad concept of "technology" and "abuses," this winds up being about cryptography, cyber-crime, and information security, much of the time. Semi-regular postings.

+ Justice For All -- Documenting the tension between the promise and the reality. Regular postings.

+ Energy & Environmental Science -- Or, How I Learned To Stop Worrying And Love Runaway Positive Feedback Loops. Depressingly regular postings.

+ Me & My Odd Musical Tastes -- I love all sorts of weird shit. Lots of metal, but very eclectic overall. Semi-regular postings.

+ Weirdly Wonderful Ideas -- Mostly humor, usually kinda messed up, typically worth every moment. Regular postings.

+ Content Warning -- Self-explanatory. Hopefully, it'll be stuff that will be fun, like talking about sexy stuff. New.

+ Cantankerisms & Crankery -- Rantings, bitchings, and particularly salty language. Because that's what you have to do sometimes, damn it. Regular postings, sorry to say.

+ Happy Feet -- Shoes and boots. Because shoes and boots. Also, shoes and boots. Although I may fold this into Femmetasia since it's somewhat related. Semi-regular postings.

+ Femmetasia -- Exploring femininity as identity and empowerment. Also, awesome femme things. Semi-regular postings.

_ Bric-a-brac -- When I can't figure out where else to put it. Semi-regular postings.

“For the first time, we’ve been able to perform a direct test of General Relativity outside of our Solar System and get solid, informative results. The ratio of the Newtonian potential to the curvature potential, which relativity demands be equal to one but where alternatives differ, confirms what General Relativity predicts. Large deviations from Einstein’s gravity, therefore, cannot happen on scales smaller than a few thousand light years, or for masses the scale of an individual galaxy. If you want to explain the accelerated expansion of the Universe, you can’t simply say you don’t like dark energy and throw Einstein’s gravity away. For the first time, if we want to modify Einstein’s gravity on galactic-or-larger scales, we have an important constraint to reckon with.”

For many of the greatest cosmic puzzles today, you can either add two new ingredients, dark matter and dark energy, or you can seek to modify Einstein’s theory of gravity. While Einstein’s General Relativity has been confirmed spectacularly under a wide variety of circumstances, the only robust tests that are independent of dark matter or dark energy assumptions occur on scales of the Solar System or smaller. That’s only for distances that are a tiny fraction of a light year, and for masses no bigger than the Sun, which should trouble you when you’re making inferences about galaxies, clusters, or the entire Universe! But thanks to a very fortunate galactic system — a strong gravitational lens that is only 500 million light years distant — we’ve been able to put Einstein’s theory of gravity to the test for galactic masses and distance scales in the thousands of light years.

Was there ever any doubt that Einstein would win again? Here’s what happened, and here’s what it means for alternative theories of gravity!

New patch is up!

Just watched S3E11 of The Expanse.

How the hell do I even talk about this episode without spoilers?

I think I'm going to be sad for a bit.

I will add that they handled the effects of zero-g really well this episode -- good and bad.

Why do I feel like I missed an opportunity to declare a Personal Assistant Challenge? +Ian Mallett and +Sevoris Doe have both gone in, and now, instead of preparing for bed, I'm mulling my own twist.

The Black Hole's In Your Head
99 words

"Any progress translating the alien text?"

"Yes, sir. It appears to be a conjecture that claims that the multiverse was created by a cascade of hypermassive black holes which created bubble universes with their own smaller hypermassive black holes, with masses for each black hole dropping until you're left with countless universes that can only produce supermassive black holes, and that these are the only universes capable of evolving life and sentience."

"My god. Do you know what this means?"

"Uh, yes, sir. This alien race wrote bad science fiction."

" . . . What?"

"Or they had kooks. We're still investigating."

"Oh."

From the preface of A Martian's History of Mars by Augusta Pamphile-Chung, Two Moon Press, 2173:

The founders of the first Martian colonies swore that they would not repeat the mistakes of colonialism, even as they professed values that guaranteed the repetition. Thus fortunes sank into the corrosive regolith and thousands gasped in the thin air heedless of the expense. Intelligence and wealth alone were not enough to bring forth the collective will necessary to sustain the Martian project. In the end, the survivors were forced to acknowledge their fundamental interdependence as key to improving their odds.

Much ado has been made of their genetics, which was certainly an important factor. More interestingly, their genetics tended to favor certain balances of neurochemicals that made them more pro-social than average. Every survivor had at minimum one or two people whose assistance helped them survive at crucial moments. In the Martian psyche, rugged individualism suffered a fatal blow. Here, on a world barely more hospitable than the Moon and full of its own unique dangers, social cohesion was survival.

And thus many Martians swore, never again -- and assured themselves that the last mistake had been made. They were of course wrong.

Colonialism is not an isolated act of will among a small group of settlers, but an imposition from the outside. No colony has started without someone back home deciding that the situation at home warranted the trip. Perhaps there was a lack of opportunity or a sense of illiberty. Maybe there was a war, a famine, an earthquake, or some other calamity that created diasporas and refugees. Sometimes, you didn't have a choice, other than prison or execution or ongoing persecution. Whatever the case, the frontier looked better than back home. And so, Martian culture is ultimately built on the failings of humanity. Familial love for your fellow Martian is borne of multiple tragedies from which we are still healing.

But do not draw the wrong conclusion. Mars would have become the Other even if it started and remained as a monoculture. All colonies are, by default, the Other. Distance and slow travel times erode away similarities. Eventually, the rift between the original colonizer and the current colony is too great.

While it is difficult to predict when that rift between worlds becomes unbridgeable, it is increasingly difficult to claim such a bridge can be built with each passing season.

What impresses me the most about this video by +Hazard-ish is that this appears to be a 100% stock triple Mun landing. No Burn Together mod, only careful design and flight planning.
