Perhaps you’ve seen the video of George Hrab and me performing his song "Death from the Skies". And perhaps you’ve seen my own show, "Bad Universe".

Now, thanks to Dana Peters, you can see them together:

After all, these are the real ways the world will end.

How big a scifi dork are you? Probably not as much as Charmax76, who made this video called "Space Girl", from the song of the same name by The Imagined Village:

Wow. I like the song, but I love the graphics. I recognized something like 3/4 of those scenes, probably more. And I like the order she put them in: you see women in somewhat trivial roles at first, but as the video progresses they get tougher and tougher. Not always, but that’s the trend. That reflects TV and movies, I think, too. Again, not always, but women have much better roles in scifi than they did even 30 years ago. The way video ends is… well. It made me sad. Doctor Who fans know why.

Another very different but clever animation for this song is also online.

Tip o’ the spacesuit visor to Buzzfeed.

Two of my favorite things in the world are Doctor Who and My Close Personal Friend Adam Savage™. So what could be better than a video combining them, and throwing in two giant Tesla coils and a Faraday cage?

I think I have nothing to add to this.

As you might expect, I am not a big fan of ghost hunting shows. Stopping every ten seconds and dramatically whispering "Did you hear that?" is not exactly the best way to run a scientific investigation.

So I’m pleased to see satires and such of those programs, and I think the web comic Dork Tower does it pretty well here.

Man, there’ve been a lot of good sciencey skeptical web comics lately. Keep ‘em coming, folks. It’s one of the best ways to spread the word.

My pal Jennifer Ouellette, who writes the delightful blog Cocktail Party Physics, was recently interviewed at Tech Republic. As usual, she’s fun to read.

On that page they embedded the video of Jennifer when she appeared on Craig Ferguson’s TV show, which I totally forgot to do when she was on! So here’s the video of her talking about her book The Calculus Diaries:

See? Told you she was cool.

With the new series of Doctor Who premiering today, why not poke a little fun?

It took me a second to recognize the voice as David Hyde Pierce, and the words are from "Treasure Planet", which I thought was actually quite an enjoyable movie.

But as an astronomer myself, I have to question the word "useless". Why, we have many uses! We help keep the coffee and polyester industries afloat, for one. And without us, people with no actual sense of humor wouldn’t be able to say "So, what’s your sign?" when they meet us, which, let me tell you, is awesomely hilarious every single time we hear it.

Anyway, if you’re expecting more out of me today, you don’t know me very well because I’ll be camped out in front of the TV waiting for the new series to premier.

Trust me. I am a doctor.

Well, it’s been a while coming, but I’m pleased to let y’all know that the third and final episode of "Bad Universe" will air on The Discovery Channel tomorrow, April 19, at 11:00 a.m. Eastern (US) time — but of course, check your local listings.

The episode is entitled "Death Stars", and is about the effects of solar flares and nearby supernovae. Like the other two, this was a lot of fun to put together, though the trip to Sandia Lab still haunts me a bit… but I won’t give that away. You’ll just have to see. I actually haven’t seen the final cut since we put it together late last year, so to be honest when I watch it tomorrow it’ll be a bit like seeing it again for the first time.

Speaking of which, my daughter will be in school when it airs, so I won’t watch it until we can see it as a family. That means I won’t be live-tweeting or anything like that.

And to answer the inevitable question: I don’t know if the network is picking it up as a series or not. I expect the ratings of the airing tomorrow may play into that, so tell a friend! Or tell a few dozen.

I hope you like it, and have at least as much fun watching it as I did making it.
