On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Paul Mecurio (  / paulmecurio  ) answer your Cosmic Queries on planets and more from the YouTube Studios in New York City.

We start with one of the most inciting questions: if we had an ocean or bath tub large enough, would Saturn float? Neil tells us about the interplanetary workings of Saturn and why a “piece” of Saturn would float in a puddle of water. You’ll hear why Saturn’s rings might only be temporary. We discuss the density of water and the science of building boats. Discover more about the Titanic and the density of ice.

Then, we explore the world of neuroscience. Neil tells us why he loves tracking the progress of modern-day neuroscience. We ponder if eventually psychologists will be replaced by simple brain adjustments once we can locate what parts of the brain cause certain emotions and behaviors. Find out the history behind the phrase “we only use 10% of our brains” and how it’s been flipped from the original statement.

We discuss if Jupiter is a failed star. Find out what our solar system would be like if we were a two-star system. Learn more about thermonuclear fusion. We dip into tidal science and investigate tidal bulges, the Moon’s relationship with the tides, and we explain why we’re actually traveling “through” low tide and high tide. All that, plus, Neil shares why putting humans on the Moon was the valuable cosmic perspective we’ve encountered yet.

Recorded at YouTube Space NY.
