Star Trek Science, Listening to Pando. May 12, 2023, Part 2

Star Trek’s Science Advisor Reveals The Real Astrophysics On Screen Few pop culture properties have lasted quite as long as Star Trek. A dozen Star Trek television shows have aired over the last sixty years—not to mention countless movies, novels, and comic books. Science concepts have always been integral to the Star Trek franchise: from warp speed travel to dilithium. But how much does the series actually accurately depict? Ira speaks with astrophysicist Dr. Erin Macdonald, science consultant for Star Trek about the legacy of the franchise, and how accurate the science is within the series.   Listen To The Largest Tree On Earth For this story, we’re taking a trip to south central Utah and into the Fishlake National Forest to visit the largest tree on earth, an aspen named Pando. The strange thing about Pando is that it doesn’t really look like the world’s biggest tree. It has rolling hills with thousands of tall, lean aspens swaying in the wind. But Pando is there, hiding in plain sight. All those tree trunks you see aren’t actually individual trees. Technically, they’re branches, and that’s because Pando is one massive tree—sprawling more than 100 acres, with 47,000 branches growing from it.   There is a lot to learn about Pando, and our guests turned to sound to understand the tree better. Together, they created an “acoustic portrait” to hear all the snaps, splinters, and scuttles that happen in and around the tree. Ira talks with Jeff Rice, a sound artist and co-founder of the Acoustic Atlas at the Montana State University Library, and Lance Oditt, executive director of the non-profit Friends of Pando, which is dedicated to preserving the tree.   Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
