Well, That's Interesting: The Evolution of Galaxies

This might be part of the explanation for why the Galactic Federation of Grooviness hasn't visited us - and why there's so remarkably little evidence that ALF has a real-life counterpart.
"Today's Spiral Galaxies Were Once the Ugly Ducklings"
Space.com (February 8, 2010)

"Beautiful spiral galaxies grew out of odd shapes that astronomers say were the ugly ducklings of the early universe.

"It's long been assumed that galaxies grow over time, and shapes change. But the main construction phase for many modern galaxies was thought to have occurred close to the beginning of time, the first few billion years after the theoretical Big Bang 13.7 billion years ago.

"Contrary to this conventional view, nearly half of the spiral galaxies of today, like our Milky Way, had peculiar shapes just 6 billion years ago — more recently than had been thought, the study found.

"If confirmed, the finding highlights the importance to many galaxies of collisions and mergers in the recent past. It also provides clues for the unique status of our own galaxy, the Milky Way, researchers said in a statement...."

"...Although our own galaxy is a spiral galaxy, it seems to have been spared much of the drama; its formation history has been rather quiet and it has avoided violent collisions in astronomically recent times. However, the large Andromeda Galaxy from our neighbourhood has not been so lucky and fits well into the 'spiral rebuilding' scenario. Researchers continue to seek explanations for this."
Short version of the article: There were a whole lot more "peculiar" galaxies 6,000,000,000 years ago than there are now. Right around that time, apparently, something happened and the universe started having a whole bunch of spiral galaxies like the one we're in.

Except that ours seems to have had less of the violent activity that normally happened.

By coincidence(?), our sun and Earth formed roughly 4,500,000,000 years back - after the spiral-making events had started.

Maybe it really was a coincidence, with no cause-effect linkage. Or, maybe (really, at our current level of ignorance, this is all pretty much speculation) the universe hadn't gone though the processes it takes for sticky stuff on a wet ball of metal and rock to grow from things wriggling in tidal basins to us - until fairly recently.

With a 1,500,000,000 year lag time, there'd still be room for some seriously old races to be around.

Who knows, maybe that fellow in the magazine was right: and we haven't met E.T. because everybody dies off. Right after reaching the awful, terrible, wasteful and (here comes a frightfully important word) unsustainable level we awful, terrible, wasteful humans are at.

I'm not all that worried, myself. But then, I'm aware that human beings stopped being "sustainable" on Earth when some maniac got the idea of poking seeds in the ground and waiting for them to grow into plants we can eat.

The way I figure it, we're at least 1,000 times over the absolute maximum sustainable limit of this planet. That's assuming that homo sapiens sapiens is strictly and only an opportunistic omnivore, with adults weighing somewhere between a hundred and a hundred and fifty pounds.

Anyway: That article on galactic evolution was interesting.

A Planet is Not a Beach Ball - Quite

There's something to be said for stories that are strictly verbal - that exist as an ordered sequence of words, and nothing else. It's the sort of tale that was told before Homer cranked out the Iliad and Odyssey, and is still going strong - take a look at how Stephenie Meyer's and Steven King's books sell.

I'm trying a words-and-pictures approach to storytelling, though.

Which adds a whole new layer of complexity. That's good news and bad news. If I pull it off - with the assistance of my oldest daughter, who's a commercial artist - the end product will be memorable. One way or the other.

Planning for extensive visuals means that I'll need to collect source material. Some of that won't be too difficult, since I'm on Earth. Problem is, most of the settings aren't on Earth: and won't be built for centuries. Make that millennia.

Never mind the issue of making everyday technology of over a dozen centuries out not look like a cheap upgrade of those silver lamé leotards that were the latest thing in "futuristic" fashion a few decades back.

Then there are the planets.

For a words-only story, describing the look of a planet from several thousand miles out isn't all that hard. We've got close-up photos of quite a variety of moons and planets here in the Solar System: Everything from Mercury to Jupiter, and Earth to Enceladus.

'Drawing' a picture of Distal in a reader's mind, all I'd have to do is use the trite "blue marble" description - or be creative and come up with something a bit less dusty.

No problem.

Distal? That's a planet that won't be found for quite a long time yet. Quite a bit like Earth, except for the parts that aren't.

My approach, so far, is to create photo-realistic images of Distal and other settings - for my daughter to use for reference, the same as she would for photos of the Great Pyramid in Egypt or a Louisiana bayou.

As a cartoon character said, "this has 'bad idea' written all over it." (Sam in Danny Phantom) Well, I'm giving this approach a shot, anyway.

Here's what I've got, so far.



Not bad, if I was trying for a beach ball. The colors and numbers were to let me see how a square array of pixels got mapped onto a sphere. That goal achieved, I refined the pattern a little, for more study:



So now I've got a beach ball that's got numbers and lines on it.

Not even close to looking like a planet.

But, I know what sort of distortions I'll be dealing with, stretching a flat graphic around a sphere. Now, to see if there's a fairly easy way to 'draw' on the sphere - and have software project what's on the sphere to a flat surface.

Not bad for part of an afternoon's work.

Eventually, I'd like to have three layers on the planet: glossy oceans, dull land, and clouds just a little over both. That's what I'd like to get - what happens, we'll see.

Epic Scale and Painting the Floor

I've got more of the "artistic temperament" in me than I like to admit. There are days when I quite simply don't feel like being creative. At all.

Today was one of those days.

But, my schedule said that I'd be writing this post: which meant that I had to come up with something, anything, today. I don't like deadlines, but they have their uses.

'Star Trek Syndrome', Cordwainer Smith, J.R.R. Tolkien and C.S. Lewis

Don't get me wrong: I was a great fan of Star Trek in the sixties. And I've enjoyed watching those movies and series of the franchise which I had means, motive and opportunity to see.

But the original Star Trek suffered from an affliction that's endemic to the various science fiction/speculative fiction/fantasy genres. Since Star Trek is a pretty big landmark on the American cultural landscape, at least, I'll pick on that venerable series and call this condition the "Star Trek Syndrome."

It's where stories with a setting 'in the future' are written with a general idea of what "the future" is like: but filling in details as the stories are done.

It can be done: and Star Trek was enormously successful. But I think that approach has intellectual landmines set under some of the well-traveled paths.

The original Star Trek series was set at some point in the future: they settled down to somewhere around 200 years. No problems there, as far as the technology was concerned. Not as far as I'm concerned.
Future Tech
Now, faster-than-light spaceships, transporters, sentient (and occasionally downright temperamental) computers? If the series had been set 20 years from now, I'd have felt my willing suspension of disbelief stretched to the breaking point. Beyond, if there wasn't some really good explanation: like a bunch of MIT students on break, stumbling on a spaceship that had crash-landed with most of the equipment in working order.

I've heard that the Romans reverse-engineered what for them was alien technology - a Phoenician ship - from a wreck they found. Ancient Romans were never really at home on the sea, and hadn't developed shipbuilding skills. They were, however, top-notch engineers: and with most of a working model to start with, they could fill in the blanks.
Future Astropolitics
Even as a teenager, though, I started wondering about the timeline of the United Federation of Planets. 200 years is a long time: but the implication in Star Trek was that we'd gone from living on one planet to having interstellar settlements and a political entity which included these grown colonies (and had members that weren't human).

In under two centuries. Well under two centuries.

That's fast work. Really fast work.

I think that a case can be made that a bunch of seriously ADHD humans barged into an existing interstellar community, decided it'd be great if everybody started living in peace, harmony and the human way - and got the United Federation of Planets going before older and wiser heads realized what had hit them.

But I'm getting off-topic. Nothing new there.
Cordwainer Smith, J.R.R. Tolkien, and C.S.Lewis
All writers, I think, are 'subcreators' to some extent. That is, they create a fictional world in which their characters act. The world of some stories are barely indistinguishable from present or past reality: the chief differences are the presence of the characters.

Even science fiction/speculative fiction/fantasy stories don't have to involve a great deal of work on the fictional world. There's quite a lot of off-the-shelf material.
  • Science Fiction
    • Ray guns
    • Space ships
      • With optional antigravity
    • Aliens that act like funny-looking human beings
    • Toxic waste that turns people into zombies
  • Fantasy
    • Swords
    • Horses
    • Flashy magic
    • Petty kingdoms
    • An economy that sounds feudal
      • Even if it isn't
Using any or all of these conventions doesn't make a story bad. Look at Robert Asprin's "Myth Adventures" novels: but then, he seems to have done some intense - and funny - analysis of fantasy's shopworn cliches.

Or take C.S. Lewis's Narnia stories. They're set in a fantasy world, and the seven of them add up to a tale that's epic in scope. But I think Lewis concentrated on the characters and plots - not on creating a heavily-detailed, internally-consistent, fully-formed subcreation. And they're good, solid stories, in my opinion.

The Middle Earth of J.R.R. Tolkien, I think, is more of a complete world than Narnia, with a more fully-developed history and set of interrelationships.

Then there's the universe of Cordwainer Smith. Particularly as it grew, it became more like the complexly-patterned world of Tolkien, than the slightly more generic land of Lewis's Narnia stories.

I like the work of all three. But I'm aiming at something closer to Tolkien or Smith, in terms of setting. What I actually accomplish - that's another matter.

Think, Plan, Then Write?

Comparing my productivity to that of #3 daughter, I may not be approaching this the right way. She's got a small but loyal fan base for her stories - which add up to a massive work - and has been making up the setting as she goes.

She's been doing what I'd call speculative fiction stories - with the same sort of issues when it comes to setting that I've got. But she's written quite a few stories. My output is - zilch, when it comes to something finished.

Like I said, I may be on the wrong track.

Or, not.

Like today.

Plan First, Then Varnish the Floor

In my youth, a stock cartoon situation was someone who had painted himself into the corner of the room - with nowhere to go. Some were funny, and all depended on the occasional lack of foresight that people exhibit.

Today, since my creative energies were nowhere to be found and my muse was on furlough, I decided to do a little research and review. I have a timeline for a particular setting that I'm rather fond of, I'd done some work on it late last year, and again this month: and it was time to go back and do a little checking.

Good thing I did.

I changed the names of several Chinese dynasties that don't exist yet (and probably never will - except in this 'future history'): for the better, I think.

Then, I took a look at the timeline I had for the future history as a whole, the voyage of one particular ship, and the transportation technology I'd assigned to this setting.

And found that I'd painted myself into a corner.

The times simply wouldn't work.
The Butler Couldn't Have Done It
It's like a ill-conceived old-fashioned mystery, where the master detective unmasks Jukes, the butler, as the murderer of Lord Thriply.

Just one problem: the author had demonstrated that Jukes had been several miles away, and couldn't have had an accomplice.

Dashing fine story, full of suspense and pathos, but the facts just don't fit together.
The Colony That Wasn't There Yet
I've got Our Heroes visiting a colorful, slightly exotic and - I hope - interesting world in one of the stories. A world where something like a quarter million people live. They're descendants of - well, that'll wait.

The point is, when I checked out the timeline: the original settlers would have arrived 10, maybe 20 years before the story starts.

They couldn't possibly have gotten to where they were - a small but thriving culture - in that length of time. Never mind the technology. The way I figure it, they'd need something like 200 years to grow from about a thousand people to a quarter million, building maybe a dozen settlements along the way.

If I'd already published something, I could have faked it - invoking some sort of technobabble as a solution.

As it is, I just shoved the story's date ahead by a couple centuries.

And, in the process of making the development of my 'space drive' - if not plausible, then internally consistent - I discovered another set of 'the butler couldn't have done it' situations.

That was good news, really, since I got an idea (born of desperation) for making a particular conflict into more than just one more 'space battle' built around 19th and 20th-century military technology that's been renamed.

It's late, and I need sleep.
