Consideration of Works Past: The Stars My Destination


This book got me kicked out of a reading club.

 

Decades ago, I was interested in this woman. She was the kind of person that beautifies their environment. I admired that.

 

Anyway, she was in this book club and I was interested in her so I joined as well. We went through several books—some good, some not. One I liked was A Yellow Raft in Blue Water by Michael Dorris. They suggested I pick an SF book. Most of the books we'd been doing were a little tame and I thought to shake things up a bit. So, I suggested The Stars My Destination. It's a rough book but I figured they were up for it.

 

I was wrong. And was thoroughly excoriated. The girl I was interested in terminated whatever minuscule interested she had in me and I left the club. The moral of the story: TSMD isn't for the squeamish.

 

TSMD is about redemption and forgiveness. Books about such things usually talk about tame things: I was a neglectful father. I did something stupid and feel wretched about it. The problem is that most people don't really do much that really needs redemption and forgiveness. Our scale of what to feel guilty about is skewed. When somebody comes around who has really done something nasty, we like to think of them as unforgiveable. We want them to think of themselves as unforgiveable. Or, better yet, don’t think bad of themselves at all so we can feel good when bad things happen to them.

 

Forgiveness and redemption is, in my opinion, a peculiarly Christian notion. If you read the Greek plays, there is payback and revenge but it's all tied up in fate. The Greeks would have had no trouble understanding Karma. But Christ comes along and says you can be forgiven for your sins. This brings to the front the concept of redemption and creates a new class of stories. Of course, once you've introduced the idea of short-circuiting guilt, payback, and karma, you've created a means by which people can evade guilt, payback, and karma. People are fine with that in their own little club but not so much for outsiders. Hence, some things become "unforgiveable". That is, unless you join the club.

 

I don't read the gospels that way. From what I can see, all is forgivable if the heart is sincere. That's the way people emulate Christ. Of course, if one can emulate Christ effectively, one can be Christ. Every man can be his own Messiah. Which makes things all Gnostic—can't have that. And so, we're back to what is forgivable and what isn't forgivable.

 

That long little digression brings us to the interesting piece of TSMD: the character of Gully Foyle, the protagonist. Foyle is an intelligent but uneducated. Able but incredibly lazy. He is sparked to greatness for the sake of revenge. Foyle was abandoned in space and subsequently bends his efforts to finding who did this, why, and exact payback on them. However, when he finds those responsible, he finds he has transformed himself into a thinking animal and discovers he actually now has a sense of right and wrong. He also becomes a messianic figure in that he has determined how humans can teleport to the stars.

 

Hence the problem the book club had with this book. In pursuit of revenge, Foyle becomes a murderer, rapist, thief and traitor. He leaves behind him a trail of broken people. At the end of the book there is the implication is he will be—or, at least, can be—forgiven. (The book never actually reaches the point of redemption. It reaches a point where redemption is possible and stops. Something I like.) The book club didn't think he'd done enough, been punished enough, or refused the possibility that he would be able to do enough, to be forgiven. I didn’t agree and we parted ways.

 

What I learned from the book was that a dark protagonist could be interesting if that protagonist is honest about it. Modern SF has few characters like Foyle. Even the vampires, parasites that they are, have been prettified or made tragic. Foyle's character has muscle. He is not pleasant. He makes no apology for what he does and only comes to see himself as loathsome after he has changed himself. Even then, he doesn’t whine about it.

 

Alfred Bester wrote a slew of wonderful short stories and a handful books. Two of them, The Stars My Destination and The Demolished Man shook the foundation of science fiction. It was a new way to write SF stories. DM is more psychological and, in my opinion, not as good as TSMD. DM was written in 1953 and TSMD in 1955. While he continued to write short stories, he didn't do any novels until 1975 when his health began to fail. Unfortunately, they were not so impressive as his first two novels.

 

The Stars My Destination was never made into a film. Just for fun, I've played with writing a screenplay of it several times but never did any actual work.

 

Hey! Anybody out there in Hollywoodland! This one would be great.

Cheese Ends, 20220911

Random mutterings from science!

 

(Picture from here.)

 

Let’s start with the SLS—NASA’s Space Launch System.

 

The SLS was initially scheduled to launch at the end of August. This was cancelled because of a coolant problem with one of the engines. Rocket engines burn hot and hydrogen/oxygen engines burn really hot. To correct for this, the hyper-cooled liquid hydrogen is circulated through the engine bell prior to combustion. This has two positive effects: it keeps the bell cool and it pre-heats the fuel. Thus, not being able to cool the engine is a big deal. Scrub launch number one.

 

Launch number two was scheduled for early September. It also got cancelled because of a hydrogen leak. Hydrogen is such a small molecule that when it’s cold and under pressure it can escape easily. The SLS sits on the pad getting continuously topped up through fast disconnect valves. Just before launch, the valves disconnect and the SLS takes off. A little hydrogen leakage is accounted for but this was too much. Next launch is latter September.

 

The issues with hydrogen are well known—this was a continuing problem with the shuttle and the SLS is based on shuttle technology. Why base the SLS on technology from the seventies? Blame congress. We have to keep Morton-Thiokol in business.

 

Personally, I want the SLS to succeed. I like the idea of NASA having its own rocket and I hate seeing NASA used as a punching bag all the time. The glorification of SpaceX gives me heartburn. Often, it’s an excuse to say government can’t do anything.

 

I don’t agree with that sentiment. For example, SpaceX has trumpeted it set the record of 40 missions this year. (See here.) No government can do that, right? Well, China launched orbital launch 36 and 37 recently. SpaceX may be the world leader in orbital launches but China is not far behind.

 

Moving on.

 

Bridgestone is moving away from using oil in the manufacture of its tires to using a plant called guayule. It takes on the order of seven gallons of oil for each tire and more than 2 billion tires are made every year. It is good news that Bridgestone (and other tire manufacturers) are moving away from oil. But 2 billion tires are going to require a lot of guayule.

 

This is an inherent problem with moving away from fossil material. When we pull oil out of the ground we’re taking advantage of millions of years of captured sunlight. It takes about 200 tons of plant material to make a gallon of crude oil. (I pulled this from here and combined it with here.) Using bamboo as an example, that’s about 28 acres over a season of about five months or 150 days. So, one tire, using seven gallons of oil, is on the order of 200 acres. You can imagine how much 2 billion tires is going to cost. (That does presume a gallon for gallon equivalent which may not occur.)

 

Those numbers weren’t in the article but it’s a problem. How to capture enough sunlight to drive civilization is a problem. One solution is for tires not to require seven gallons of anything. And maybe not require 2 billion per year.

 

On a similarly negative note, Greenland is going to raise sea levels.

 

A recent study has managed to model the quantity that is already baked in to Greenland glacier melting. They can’t say when it’s going to happen but by neglecting that aspect of things they can tell how much.

 

They did this by calculating how much of the Greenland ice is vulnerable to current conditions, current conditions not going away any time soon. This allowed them to calculate how much water would come from those vulnerable glaciers. The answer was enough to raise the world sea level close to eleven inches. When? That is not part of the study but warming is still increasing and we’re not close to stopping the problem.

 

On that happy note, another study has suggested it was actually hotter 55 million years ago than previously thought. This, probably not coincidentally, took place in or around the Paleo-Eocene Thermal Maximum, though the study doesn’t reference the PETM. The timing is about right in that the study takes place between 35 and 60 million years ago and the PETM took place about 55.5 million years ago.

 

The point of the study was that since the time was hotter with understood CO2 amounts, the environment might be more sensitive to CO2 than previously thought.

 

The technique was pretty interesting. The measurement was of carbon and oxygen isotopes in the shells of foraminifera. Earlier studies measured the oxygen/carbon isotope ratio directly. However, depending on temperature, isotopes “clump” together. Isotope clumping can be calibrated to temperature without the need of determining salinity or other factors. That’s the good news. Bad news is, of course, it was significantly hotter than previously estimated.

 

Let’s go to some not-quite-so-negative news prior to the finale.

 

This involves my favorite small animal, tardigrades. Tardigrades are tiny animals called “water bears” that live in water droplets in moss. Or salt or fresh water sediments. Or in deep sea trenches. They have my vote for the most likely alien visitor. They go from a normal moist environment to a tun state when that water dries up. When in tun, tardigrades can withstand vacuum, high impacts, etc.

 

Tardigrades dehydrate pretty much completely when going into tun and they stay that way until they either fall apart or get more water. It’s been a mystery how they do that.

 

In 2017, a paper demonstrated they used a disorder protein (“tardigrade-specific intrinsically disordered protein” or TDP) that suspends the cell so it doesn’t collapse when the water disappears. The new paper presents a different mechanism. Instead of suspending in a glassy TDP substance, the new paper suggests that “cytoplasmic-abundant heat soluble proteins” (CAHS) are responsible. These form gel-like filaments rather than glassy material. The filaments appear during dehydration and gradually disappear during rehydration.

 

What’s even more interesting is they spliced the CAHS genes into insect and human cells. The proteins behaved the same way in insect cells and had limited functionality in human cells.

 

Finally, not a down note but some sad news: Frank Drake, creator of the Drake Equation, has died.

 

Drake was 92 and died peacefully in California. He had a long and distinguished career independent of his famous equation as a radio astronomer. Asteroid 4772 Frankdrake is named after him.

 

The Drake Equation was an attempt to formalize the probability that there was intelligent life in the Milky Galaxy. It did not solve the problem. It only presented it as a mathematical proposition shown above.

 

Where:

  • N  : Number of detectible Milky Way civilizations
  • R*  : Number of suitable stars created every year.
  • fp   : Fraction of stars with planets
  • ne  : Number of habitable planets
  • fl    : fraction of planets where life actually appears
  • fi    : fraction of life bearing planets where intelligence appears
  • fc   : Fraction of those planets where a technology arises that can be detected
  • L   : Length of time a given technological civilization produces detectable signs.

We are only now getting a sense for some of these variables. R*, for example, depends on what kind of star we’re considering. If we’re only talking about G-type stars, like our sun, than that is one rate of formation. However, recently red dwarfs are also being considered since they are so long-lived. They have issues, too, like lethal solar flares. fp has some data, too, from the Kepler and TESS missions. We have an inkling of ne  in that we’re getting an idea of how many rocky planets might be in the habitable zone but no real idea if they're habitable. The rest are unknown. Thus, the Drake Equation is really a valuable mechanism for discussion and speculation.

 

Thanks, Frank. We’ll miss you.
