Ten Issues for Hard Science Fiction

Monday, September 8th, 2008

There are a number of issues that continue to keep coming up in hard science fiction, or any science fiction trying to get the facts right.   I just helped my collaborator here a few days ago answer a reporter’s questions on one of these (humans expelled into space without space suits).   These things should always […]

Science Fiction in Science

Wednesday, September 3rd, 2008

Sometimes I tell people that I write science fiction for Tor and the Astrophysical Journal. That’s tongue in cheek, mostly, but there is a lot of stuff that scientists work on that is, for want of a better term, “science fiction.” Except that it’s very well-informed with science and worked out in some detail. It’s […]

What is a Quasar?

Friday, August 22nd, 2008

When I travel and meet a lot of new people, they often ask what I do. When I tell them that I’m an astronomer, and they don’t immediately mumble something about liking astrology or make some other outrageous statement as sometimes happens, they’ll often follow up and ask what, specifically, is my specialty. “Quasars,” I […]

Rocket Scientists Are Stupid Smart People

Wednesday, August 20th, 2008

OK, maybe, maybe not, but Robert Lemos writing for wired.com, playing up the hyperbole, makes them sound like it with this pronouncement: Rocket Scientists Say We’ll Never Reach the Stars. Which I don’t think anyone quoted in the article ever quite says. Never say never, especially in cases of engineering. It isn’t impossible to reach […]

Online Astronomy Resources for Writers

Tuesday, August 5th, 2008

I throw a lot of links at the writers attending the Launch Pad Astronomy Workshop for Writers. I usually do it on the fly before a lecture, or embedded within lecture slides. It made sense to pull them out and to put them in one place with a little organization. The idea is that these […]

Star Colors

Tuesday, July 29th, 2008

Phil Plait at Bad Astronomy addresses the question of why are there no green stars.   It’s a nice post and brings together astronomy and biology in interesting ways, and reminds me of the posts I did a couple of months ago for a friend who’d just sold a story about life on a world orbiting […]

Why Do We Crave Stories?

Friday, July 25th, 2008

Earlier this week, award-winning sf writer Nancy Kress (who is attending Launch Pad next week, by the way) wrote a short post about “the point of fiction.” I agree with her that a primary point is indeed “to decide what matters.” Last night, I was starting to reread Robert McKee’s excellent book, Story: Substance, Structure, […]

Does Science Fiction Dampen Interest in Space Exploration?

Monday, July 14th, 2008

Here’s the brief article quoting Buzz Aldrin: I blame the fantastic and unbelievable shows about space flight and rocket ships that are on today.   All the shows where they beam people around and things like that have made young people think that that is what the space program should be doing. It’s not realistic…if you […]

Black Hole to Eat the Earth?

Saturday, June 21st, 2008

The Large Hadron Collider (LHC) is going on on-line and will produce the most energetic man-made collisions ever created.   There have been concerns that this will produce various doomsday scenarios, but as Dennis Overbye writes in the New York Times citing a recent safety report, the particle accelerator isn’t going to create a runaway black […]

Top 10 SF Movie Lists and the Top SF Movie of All Time (Can You Guess It?)

Wednesday, June 18th, 2008

First, I am providing my own personal list in response to yesterday’s American Film Institute list. I’m going to overlook some questionable science in a few movies, and not overweight the science. I am going to leave out fantasy, including superhero movies and Star Wars — mitochlorians or whatever they were called does not make […]

Absolute Hot?

Tuesday, June 10th, 2008

Okay, I thought this idea was dumb before I read the article. There’s an interesting discussion to be had about extremely hot temperatures, which I didn’t appreciate until I read it. Share/Bookmark

Green “Stars” for Real?

Tuesday, June 10th, 2008

In light of the recent posts about the red M stars, as red as they’re perceived to be anyway, I wanted to bring up the issue of the non existence of green stars. A star with the appropriate temperature, not too dissimilar from that of our own Sun, has a spectrum that peaks in the […]
