After a full day in a clean suit, there’s nothing like …

a dip in the hot tub.

NASA astronomer Andrew Booth spends his days working with lasers, developing some of the word’s most advanced telescopes. When he gets home from work, he loves to pour a glass of wine and slip into the hot tub.

And ponder some of the weirder aspects of astrophysics.

Orbital Path host Dr. Michelle Thaller (who happens to be married to Booth) rather avidly shares this enthusiasm.

For Orbital Path’s first adventure in Hot Tub Physics, the topic is: The weirdness of light. And something called interferometry. And telescopes that don’t work unless a single particle of light can be two places at exactly the same time.

Which raises the question: Are we living in a parallel universe?

Join us in the hot tub as we get wet and weird (the water’s just fine)!

Orbital Path is produced by David Schulman and edited by Andrea Mustain. Production oversight by John Barth and Genevieve Sponsler. Hosted by Michelle Thaller.
