"We might unwittingly create the first sentient robots."

http://io9.com/5931389/why-our-current-missions-to-space-could-create-sentient-robots

"Space is the domain of robots. NASA is about to land the semi-autonomous robot Curiosity on Mars within the next few days, where it joins its two less-sophisticated robot brethren, Spirit and Opportunity. There's a good reason why these rovers are the first Earthlings first to set foot — or rather, tire treads — on Mars.

"Even the simplest robot can survive in space better than a human can. As we program more and more of our smart machines to explore space, we might discover a lot more than microbial life in the waters of Europa. Instead, says celebrated science historian Richard Rhodes (author of The Making of the Atomic Bomb), we might unwittingly create the first sentient robots."

Hawking on time travel

It really is that simple. If we want to travel into the future, we just need to go fast. Really fast. And I think the only way we're ever likely to do that is by going into space. The fastest manned vehicle in history was Apollo 10. It reached 25,000mph. But to travel in time we'll have to go more than 2,000 times faster. And to do that we'd need a much bigger ship, a truly enormous machine. The ship would have to be big enough to carry a huge amount of fuel, enough to accelerate it to nearly the speed of light. Getting to just beneath the cosmic speed limit would require six whole years at full power. 

The initial acceleration would be gentle because the ship would be so big and heavy. But gradually it would pick up speed and soon would be covering massive distances. In one week it would have reached the outer planets. After two years it would reach half-light speed and be far outside our solar system. Two years later it would be travelling at 90 per cent of the speed of light. Around 30 trillion miles away from Earth, and four years after launch, the ship would begin to travel in time. For every hour of time on the ship, two would pass on Earth. A similar situation to the spaceship that orbited the massive black hole. 

After another two years of full thrust the ship would reach its top speed, 99 per cent of the speed of light. At this speed, a single day on board is a whole year of Earth time. Our ship would be truly flying into the future. 


The slowing of time has another benefit. It means we could, in theory, travel extraordinary distances within one lifetime. A trip to the edge of the galaxy would take just 80 years. But the real wonder of our journey is that it reveals just how strange the universe is. It's a universe where time runs at different rates in different places. Where tiny wormholes exist all around us. And where, ultimately, we might use our understanding of physics to become true voyagers through the fourth dimension.

Shared Worlds

Thinking of shared worlds again ... playing Fallout 3 and a new D&D 4E campaign has me itching to world-build. I think my perfect vision is a wiki based around a concept that would be split into different eras or specialties -- and four or five writers would contribute, each specializing in a corner of the universe that may or may not overlap with the others. One of the basic rules would be that whatever you did had to build on what someone else did, but not negate it.

It would have to be a group that worked together well, that was keyed into the same ideas and wanted similar things from the project. There would bound to be disagreements, but hopefully the wouldn't turn nasty, and would ultimately lead to something even better than what was there before.

The ultimate goal would be to have a world that any of the contributors could then set stories within -- novels, screenplays, games or whatever they wanted to write.

I started something with this basic idea with Pato -- god, about a year ago now. But I haven't ever been entirely comfortable with the "hardware" issue -- with the wikis that we found, and with my own capabilities of building it. So I've tended to let the actual wiki sit, even as I keep taking notes on the world and even writing stories set within that world.

Anyway. I've got airships and tentacles on the brain these days.

Everything I Know About Time I Learned From Steve Miller

I was just reading A Brief History of Nearly Everything, particularly a chapter that dealt with the age of the universe -- where I'm at right now some scientist or other has speculated that the universe is 20 billion years old. And it got me to thinking -- probably too simplistically -- but it got me to thinking, how can we really think about "years" on a scale like that?

Because a "year" is the time it takes for the earth to travel around the sun. But if the earth is, what, 4.5 billion years old, or something like that -- how can we measure years before the earth existed? If there was no earth to travel around the sun, I mean. If "time" is relative to gravity, if time is relative to movement through space -- I don't know if we can think about "20 billion years" once we're talking about something off of the planet earth, can we? I mean relative to us, sure -- it takes 76 years for Haley's Comet to swing within viewing distance of the earth. But that's 76 years for *us* -- if we were to attach a pocket watch to Haley's Comet, would it calculate the same amount of time?

I think I've read that if you take an airplane from, say, New York to Los Angeles -- when you get off that plane you're a little younger than the folks you left behind in New York, by virtue of the speed you've traveled through space. Space meaning physical space, not outer space. So if even *that* movement alters one's own perception of time...

I guess ultimately what I'm saying is, how can we talk about "20 billion years" when there haven't BEEN 20 billion years -- meaning, 20 billion passages around the sun by the earth?

And somewhat separate -- what if the earth has made some passages around the sun, or WILL make some passages around the sun, either faster or slower? Is it still a "year"? Are we really talking about "20 billion theoretical revolutions around the sun"? We already have a concept of a "Martian day," since it's something like 23.5 hours as compared to our 24 hours ...

I realize I'm thinking myself in circles, and I just got out of bed to type this as a means to not forgetting all about it in the morning. I'm not a stupid guy, but once you start talking about physics or astronomy I get easily confused. I'll just post this, move it to the back of my brain for now, and then go back to reading.

Interlude 2

There was something I wanted to share with you, but it doesn't seem like I really can. (But then that's what this blog has become, yeah?) It would seem like I was being petty, or that I felt things that I really didn't, or that I didn't feel things that I really did.

I won't quote it exactly, since that's not the sort of thing I believe in tonight. But it's a sentiment expressed in Michael Ondaatje's DIVISADERDO: "Romance is romance, and not a promise of permanence."

And I guess that's true. I guess objectively I believe that. And I guess (all the same) that you (once again, as always, I) never really think it will happen to (me).

The New Messiah

from the So I Won't Lose It Dept....

The Beat's look at the cancellation of DC's Minx line.

...another lesson in how Comics Just Don't Get It, burying Minx comics in with the graphic novels and manga, instead of fighting to get them in with the YA titles. I can attest to the fact that Barnes & Nobles have a graphic novel section in their childrens' departments -- it's young readers stuff, to be sure, not young adult -- but this reminds of how books like ULTIMATE SPIDER-MAN were supposed to reach audiences AMAZING SPIDER-MAN couldn't, but just wound up being bought by the same folks who liked Spider-Man to begin with.

More and more I'm thinking: Comics Yay, The Comics Industry Nay. But then I guess sales trends will take care of that.

(Also? The new Jenny Lewis cd is my new girlfriend.)

Command D

So I won't lose it: a run-down on KAMANDI. I love the "world name" Kirby came up with -- "Earth, AD."

#7: Robots Conquer Earth

6 Ways to End a TV Series.

Worldbuilding

Found via Warren Ellis -- it's from M. John Harrison's blog:

"Every moment of a science fiction story must represent the triumph of writing over worldbuilding.

"Worldbuilding is dull. Worldbuilding literalises the urge to invent. Worldbuilding gives an unneccessary permission for acts of writing (indeed, for acts of reading). Worldbuilding numbs the reader’s ability to fulfil their part of the bargain, because it believes that it has to do everything around here if anything is going to get done.

"Above all, worldbuilding is not technically neccessary. It is the great clomping foot of nerdism. It is the attempt to exhaustively survey a place that isn’t there. A good writer would never try to do that, even with a place that is there. It isn’t possible, & if it was the results wouldn’t be readable: they would constitute not a book but the biggest library ever built, a hallowed place of dedication & lifelong study. This gives us a clue to the psychological type of the worldbuilder & the worldbuilder’s victim, & makes us very afraid."
