On this episode of StarTalk Radio, we’re celebrating you! The fans! Neil deGrasse Tyson and Chuck Nice are answering a special batch Cosmic Queries submitted by some of our most supportive fans.

Before we dive into questions, Neil and Chuck reflect on IQ tests. What happens when the person taking the test is smarter than the person who wrote the test? You’ll learn what it was like for Neil to be a student. Then we dive into the questions. Why are there so many spirals in nature? Neil tells us about his experiences filming Cosmos in a redwood forest and seeing spirals along the trunks of trees. You’ll learn about spiral galaxies and “density waves.”

Then, we investigate the rise and fall of the Arecibo Observatory. Neil gives us a history lesson on the significance of the telescope and it’s functionality. We discuss the slow demise and eventual shut down of the telescope. You’ll also learn about the Five hundred meter Aperture Spherical Telescope in China that’s currently the world’s largest filled-aperture radio telescope. Neil also explains why the plight of the Arecibo Observatory is a metaphor for science in America.

We ponder if machines can ever truly make art. Neil gives us his definition of art and why he thinks the only way for a machine to make art is to be a genuine artificial intelligence. What’s the most fascinating thing we’ve discovered in the known universe? Neil tells us why you can’t beat black holes. You’ll hear how scientists first discovered signatures of a black hole. All that, plus, discover more about the expansion of the universe and if it will end with the annihilation of spacetime.
