Subnodes, Emily Quang here.

Science fiction is all about alternate realities.

Undiscovered worlds, warped timelines.

It feels especially apt this year when we're dreaming about what might be in store next year

and maybe even the year after that.

And while we're at it, why stop at this galaxy?

We thought this week we'd bring you a very special lineup devoted entirely to science fiction.

Strap on your gravity suits and polish your lightsabers.

It's about to get real nerdy.

We're going to start with one of our favorite episodes from earlier this year where Jeff

Brumfield and I dissect what some science fiction movies get wrong about the science of

space propulsion.

Happy science fiction week, Earthlings.

You're listening to shortwave from NPR.

Well, well, well.

NPR science correspondent Jeff Brumfield, guess you decided to poke your little head up again

for another shortwave episode.

Emily, it's been too long.

And today I'm pleased to tell you I've got something fun to talk about.

Thank goodness.

Okay, let's go.

So, to get things going, just start by telling me your favorite sci-fi shows or movies.
