From Chapter 3 (page 50 of the paperback edition) of Communion of Dreams:
Apparent Gravity was the third major application of the theories set forth in Hawking’s Conundrum, the great opus of Stephen Hawking which was not published until after his death in the earlier part of the century. He hadn’t released the work because evidently even he couldn’t really believe that it made any sense. It was, essentially, both too simple and too complex. And since he had died just shortly before the Fire-Flu, with all the chaos that brought, there had been a lag in his theory being fully understood and starting to be applied.
But it did account for all the established data, including much of the stuff that seemed valid but didn’t fit inside the previous paradigms. Using his theories, scientists and engineers learned that the structure of space itself could be manipulated.
In the news today:
Stephen Hawking’s ‘breathtaking’ final multiverse theory completed two weeks before he died
A final theory explaining how mankind might detect parallel universes was completed by Stephen Hawking shortly before he died, it has emerged.
Colleagues have revealed the renowned theoretical physicist’s final academic work was to set out the groundbreaking mathematics needed for a spacecraft to find traces of multiple big bangs.
Currently being reviewed by a leading scientific journal, the paper, named A Smooth Exit from Eternal Inflation, may turn out to be Hawking’s most important scientific legacy.
I frighten myself sometimes.
Farewell, Professor Hawking. Challenged in body, you challenged us with your mind.

An international team of scientists from the Search for Extraterrestrial Intelligence (SETI) is investigating mysterious signal spikes emitting from a 6.3-billion-year-old star in the constellation Hercules—95 light years away from Earth. The implications are extraordinary and point to the possibility of a civilization far more advanced than our own.
The unusual signal was originally detected on May 15, 2015, by the Russian Academy of Science-operated RATAN-600 radio telescope in Zelenchukskaya, Russia, but was kept secret from the international community. Interstellar space reporter Paul Gilster broke the story after the researchers quietly circulated a paper announcing the detection of “a strong signal in the direction of HD164595.”
Huh.
Even if it is a signal directly beamed at us, it would require a Kardashev Type I civilization (about 200 years beyond where Earth is currently). If it is just beaming off in all directions, it’s another whole magnitude of power — about a Kardashev Type II.
Huh.
Yeah, I’d say it warrants paying attention to.

Oh, this is just delightful:
Here there be robots: A medieval map of Mars
Recently I’ve been really into old maps made by medieval explorers. I thought it would be fun to use their historical design style to illustrate our current adventures into unexplored territory. So here’s my hand-drawn topographic map of Mars, complete with official landmark names and rover landing sites.
Go check out the whole thing, but here’s a glimpse of the map itself (which is much larger on the original post):
You can even support the artist and buy a copy! Quick, before they’re all gone!

You should read this: Born to Be Conned. Seriously, it’s a very good examination of the human tendency to construct narratives to explain the world around us, and how that trait can easily be manipulated and used against us. Here’s a good passage, explaining why we’re susceptible to grifters of every sort:
Stories are one of the most powerful forces of persuasion available to us, especially stories that fit in with our view of what the world should be like. Facts can be contested. Stories are far trickier. I can dismiss someone’s logic, but dismissing how I feel is harder.
And the stories the grifter tells aren’t real-world narratives — reality-as-is is dispiriting and boring. They are tales that seem true, but are actually a manipulation of reality. The best confidence artist makes us feel not as if we’re being taken for a ride but as if we are genuinely wonderful human beings who are acting the way wonderful human beings act and getting what we deserve. We like to feel that we are exceptional, and exceptional individuals are not chumps.
The piece also reminds me a lot of Carl Sagan’s The Demon-Haunted World, because of this insight:
Before humans learned how to make tools, how to farm or how to write, they were telling stories with a deeper purpose. The man who caught the beast wasn’t just strong. The spirit of the hunt was smiling. The rivers were plentiful because the river king was benevolent. In society after society, religious belief, in one form or another, has arisen spontaneously. Anything that cannot immediately be explained must be explained all the same, and the explanation often lies in something bigger than oneself.
I don’t mean to pick on religion here, just to point out that this is a very human trait. In fact, I have often wondered whether it is a defining human characteristic, something which could easily set us apart from other intelligent species. It’s fairly easy to imagine how intelligent, sophisticated, technologically-advanced civilizations could be constructed by species which don’t have this human gift for storytelling. You can, after all, have curiosity and scientific inquiry, art and poetry, even narrative and historiography, without having something like literary fiction.* I think that it might be interesting to write a science fiction story/series based on the premise that humans become the storytellers of the galaxy, because of our unique ability to create explanation narratives unrelated to reality.
How very meta.

From Chapter 3 of Communion of Dreams:
Apparent Gravity was the third major application of the theories set forth in Hawking’s Conundrum, the great opus of Stephen Hawking which was not published until after his death in the earlier part of the century. He hadn’t released the work because evidently even he couldn’t really believe that it made any sense. It was, essentially, both too simple and too complex. And since he had died just shortly before the Fire-flu, with the chaos that brought, there had been a lag in his theory being fully understood and starting to be applied.
But it did account for all the established data, including much of the stuff that seemed valid but didn’t fit inside the previous paradigms. Using his theories, scientists and engineers learned that the structure of space itself could be manipulated. The first major application led to practical, safe, and efficient fusion power. Rather than forcing high-energy particles together, the forces keeping them apart were just removed. Or, more accurately, the manifestation of space between them was inverted. It took very little energy, was easy to control, but only worked in a very localized fashion
Then there’s this excellent non-technical explanation of a new theory of Shape Dynamics. An excerpt or two:
Their latest offering is something called “shape dynamics.” (If you’ve never heard of shape dynamics, that’s OK—neither have most physicists.) It could, of course, be a dead end, as most bold new ideas in physics are. Or it could be the next great revolution in our conception of the cosmos. Its supporters describe it as a new way of looking at gravity, although it could end up being quite a bit more than that. It appears to give a radical new picture of space and time—and of black holes in particular. It could even alter our view of what’s “real” in the universe.
* * *
In most situations, shape dynamics predicts what Einstein’s theory predicts. “For the vast majority of physical situations, the theories are equivalent,” Gryb says. In other words, the two frameworks are almost identical—but not quite.
Imagine dividing space-time up into billions upon billions of little patches. Within each patch, shape dynamics and general relativity tell the same story, Gryb says. But glue them all together, and a new kind of structure can emerge. For a concrete example of how this can happen, think of pulling together the two ends of a long, narrow strip of paper: Do it the usual way, and you get a loop; do it with a twist and you get a Möbius strip. “If you glue all the regions together to form a kind of global picture of space and time, then that global picture might actually be different.” So while shape dynamics may recreate Einstein’s theory on a small scale, the big-picture view of space and time may be novel.
Another prediction come true?
Not really — there were intimations of this theory when I was working on CoD, and it is a *very* long way from being accepted as valid, as the Nova article discusses.
But still …
