A friend of mine emailed me to ask about something he remembered Timothy Leary saying in a speech 30 years ago: “Our enemy is gravity. That’s why we die. We are all fighting the earth’s gravitational pull. We will live forever, once we escape the pull from Mother Earth.” Leary had some kooky ideas for […]

The other day I linked to this story from the Economist called “Publish and Be Wrong.” They were making the criticism that scientists may be overselling their results to get into the most prestigious journals, and hence the top journals were more likely to be publishing “wrong” results. Well, I have been thinking more about […]

I double majored in college in electrical engineering and space physics, before going on to get advanced degrees in astronomy. I made a conscious choice to pursue science rather than the more lucrative engineering. Why does this matter? Why should you care? I am interested in the issue of politics and science, and the more […]

Over at sfsignal.com, there’s a new Mind-Meld topic I’m participating in: Q: Astronaut Buzz Aldrin said fantastic space science fiction shows and movies are partly responsible for the lack of interest in real-life space exploration among young people. Do you agree with this assessment? Why? In addition to myself, participants include Larry Niven, David Brin, […]

According to this article: NASA has commissioned a specialist to recreate the smell of outer space – which has been described as being similar to fried steak and hot metal. Too bad there’s not another presidential debate, or we could hear about the money John McCain will save us by stopping such foolishness. (Sorry for […]

Really interesting stuff on James Nicoll’s blog: The facts are wrong Gene Ward Smith asks what looks like a reasonable question on rec.arts.sf.written The mass-luminosity relationship for main-sequence stars was known [during] all of the Golden Age, and hence it was [known] that all of those sfnal Rigellians and Denebians were nonsensical, Was this simply […]

James Harris calls for more real science in science fiction, and discusses how there’s science as fantastic as science fiction already out there to inspire and to steal from. Steal is my word, not his, but it’s a time-honored tradition in the fiction business and the sincerest form of flattery. I remember reading about how […]

This is my opinion. I like to think it’s well-informed as an astronomer and science fiction novelist who spends way too much time thinking about such issues, but the fact is we’re too ignorant on this topic to speak with a lot of authority. If nothing is there, we won’t find anything, for instance. But […]

In my post about Ten Things I Hate About Science Fiction I wrote: 4. Inconsistent or illogical time travel. It seems like writers just make up rules for time travel that make no sense a lot more often than other types of stories. I mean, WTF was with that fading photograph in Back to the […]

There’s a basic misconception floating around out there about the size of the universe. Astronomers trying to be accurate are probably guilty for some of this because we always hedge our bets. We know that the universe is big, really big, from Douglas Adams. He’s right, but there’s a difference between infinitely large and really […]

It seems that massive Earth-like planets exist in other star systems, rocky bodies with masses several times higher than that of the Earth. Some scientists are trying to understand the geological structure, volcanism, outgassing, and plate tectonics. This is probably more detail than you might need to write a story, but thinking about these details […]

One of the other issues I didn’t mention yesterday that comes up in hard science fiction is figuring out the parameters for artificial gravity. It’s relatively straightforward. Here’s the amazing scene approaching the orbiting space station: It’s possible to calculate the gravity on board the outer ring. Wikipedia provides the necessary information in its article […]
