Neutrinos and the Day After Tomorrow

In Episode 178 of the Gerry Anderson Podcast, Chris Dale featured the film The Day After Tomorrow on his Randomizer segment. This is not the 2004 film about climate change. Instead, it was a 1975 segment of an American after school series called Special Treat, which offered educational programming aimed at teenagers. It appeared soon afterward on the BBC. The show was produced by Gerry Anderson and starred Nick Tate, Joanna Dunham, and Brian Blessed. The show was produced between seasons one and two of Space: 1999 and it shares models and props with the television show. One of the show’s goals was to introduce kids to Einstein’s theory of special relativity. Anderson apparently had the notion that he might turn this into a series, so wrote it in such a way that more episodes could follow the special.

I was intrigued by Dale’s discussion of the show on the podcast, so decided to seek it out. The episode is available on the DVD The Lost Worlds of Gerry Anderson, along with several other one-shot gems produced by Anderson. The Day After Tomorrow reminded me of what Lost in Space might have been like without the Robot or Dr. Smith. Two families travel in a near light-speed craft to Alpha Centauri and beyond. Of course, this becomes our “vehicle” for discussing the effects of special relativity. Nick Tate, best known as Alan Carter in Space: 1999, is the captain and he travels with his daughter. Brian Blessed and Joanna Dunham play a husband and wife scientist team with a son. Like the Robinson kids in the early episodes of Lost in Space, these kids are smart, but manage to avoid crossing over into the annoying territory that kids in science fiction shows have been known to do. Since this is 1975 and well before Brian Blessed became known for “Gordon’s Alive!” in Flash Gordon, he delivers a subdued and believable performance as a scientist.

While I was prepared to see the cast to discuss the wonders of Einstein’s theories, there was a moment that truly surprised me about two-thirds of the way into the show. Joanna Dunham’s character, Dr. Anna Bowen, is observing a red giant star when she warns that she’s detecting “massive neutrino emissions from the red sun.” A moment later, the sun explodes into a supernova! As it turns out, the notion that a supernova would be preceded by a neutrino burst is a theory proposed by my graduate advisor, Dr. Stirling Colgate, in a 1966 paper. This theory would finally be demonstrated in 1987 when a neutrino burst was detected just before Supernova 1987A was observed.

It’s hard to look at the special and say that it was full of groundbreaking or mind-blowing science. Mostly it seemed like a fun, action adventure show that tossed in some tidbits about special relativity. Still, writer Johnny Byrne had done some homework in astronomy to know that it had been theorized that a neutrino burst would precede a supernova explosion. As a science fiction writer, I know story and character come first, but I really do appreciate a moment like this when I see a writer going the extra mile to understand his subject matter.

  1. That seems cool seeing something in a science fiction show that came from a theory of one of your instructors! I just checked the Wikipedia article on “Supernova neutrinos,” and it has “Colgate and White, and independently Arnett identified the role of neutrinos in core collapse, which resulted in the subsequent development of the theory of supernova explosion mechanism.” It doesn’t have the first name of those three people, which it really should have. I can add them if I get the information and an authoritative source I can reference. (Article at

    So two questions:

    1) Do you have the full names (at least first and last name) of the three people mentioned?

    2) Do you know an online source that would have them and, if not, do you know a physically published source that does?

    As for *Lost in Space*, I saw the original, unaired pilot without Dr. Smith and Robot. It would have made for a very different series. (And of course the character of Dr. Smith changed radically early in the aired series.)

    • Thanks, Alden. I suspect the lack of first names indicates the article was written by someone in the field, We often refer to papers by the last name or names of the primary contributors. At any rate, the Colgate and White paper was by Stirling A. Colgate and Richard H. White. Here’s the link to the abstract at NASA’s Astrophysical Data System. At the link. you’ll find bibliographic information to the original article, which appeared in the Astrophysical Journal:…143..626C/abstract

      Arnett is W. David Arnett and I believe the paper they refer to in the Wikipedia article is this one:

      Arnett refers to a 1964 paper by Colgate and White. That appears to be an earlier version of the 1966 work, which both parties would have built on.

      Yes, I have a copy of the original Lost in Space pilot. It was a much more serious tone. The Day After Tomorrow does have a similar tone, but fewer giant cyclopes.
