In this week’s episode of StarTalk Radio, Neil deGrasse Tyson and Chuck Nice are back together again as they answer fan-submitted questions that take us across the universe and back. Coming to you from the Cosmic Crib, a.k.a. Neil’s office, our duo is ready for any cosmic quandaries thrown their way.
Find out why the death of the universe will happen “not with a bang, but with a whimper. And not in fire, but in ice.” Ponder if you can have a universe inside another universe. Discover more about the cosmic microwave background. Explore the concept of the holographic universe. (If you want more on the holographic universe, be sure to check out our show from a few weeks back, Cosmic Queries – Out There, where Janna Levin and Neil cover the topic in greater depth.)
Learn more about the entwinement of time and space and why one can’t exist without the other. Unpack gravitational redshift and time dilation, and investigate whether or not outgoing electromagnetic signals from celestial bodies can be slowed down by time dilation. Find out more about merging black holes and Hawking radiation.
Investigate the science behind electron microscopes and why they allow us to see farther down than light-based microscopes. We calculate how a wheelchair would function in zero gravity, and take a look at the Fermi paradox and “the great filter.” Lastly, Neil strongly advocates for common core math in schools. All that, plus, Chuck and Neil ponder if the urge that causes us to explore might also be the same urge that destroys us in the end.
Please join us tomorrow night for Cosmic Queries – Across the Universe at 7pm ET right here on our website, as well as on Apple Podcasts, Google Play Music, SoundCloud, Spotify, Stitcher, and TuneIn. If you’re an All-Access subscriber, you can watch or listen to this episode ad-free at 7pm, too.
That’s it for now. Keep Looking Up!
