A fan asks if, from a cosmic perspective, entropy will eventually give way to equilibrium, or is the order of the Universe just Newtonian? To answer this Cosmic Query, Neil deGrasse Tyson explains to Chuck Nice how a system’s source of energy is what determines order, complexity and entropy. On a comically related note, Neil and Chuck discuss the Nobel Prize-winning discovery of blue LEDs.
Confused about gravity waves and gravitons? You’re not alone! Especially since we’ve never directly detected either one. But, as Neil deGrasse Tyson says to Leighann Lord in answering a fan’s Cosmic Query, “We’ve got top people working on it.” Find out about LIGO (the Laser Interferometer Gravitational Observatory) and how we’d know if a gravity wave passed across us. You’ll also hear about how a scientist from Bronx High School of Science won the Nobel Prize in Physics for using binary pulsars to measure gravity waves.
Stop me if you’ve heard this one: Bill Nye the Science Guy and Astro Mike Massimino get into an elevator with a Congressman… No, it’s not a joke, but it is the subject of a fan’s Cosmic Query. What do you think they would tell that legislator about why it’s so important to fund space exploration and NASA?
A fan wants to know how long before we can mount a manned mission to explore Titan, Saturn’s largest moon. Bill Nye, the CEO of the Planetary Society, and NASA astronaut Mike Massimino, discuss practical issues like radiation shielding and bone loss. But it’s comic co-host Eugene Mirman‘s suggestion that Astro Mike calls “genius.” Decide for yourself in this StarTalk Radio Cosmic Query “Behind the Scenes” video.
A fan wants to know what Cubesats are and how they work — and so does comic co-host Eugene Mirman. Luckily for them, and us, guest host Bill Nye the Science Guy and NASA astronaut Mike Massimino are both big fans of the little satellites and have the facts at their fingertips.
In this Cosmic Query, a fan asks about the worst-case scenario for misuse of a warp drive. Sure enough, astrophysicist Neil deGrasse Tyson comes up with one involving backwards time travel that creates a timeline-destroying paradox. Then it gets really weird, when Neil and co-host Eugene Mirman talk about altering history, killing grandparents, sex and jumping out of closets. Watch for yourself.
A fan wants an explanation of magnets and magnetism, but little did he know his Cosmic Query would be answered by none other than Bill Nye the Science Guy. Bill was our guest host for this episode, along with guest NASA astronaut Mike Massimino and comic co-host Eugene Mirman. Find out how Earth’s magnetic field arises and helps protect our atmosphere, and why Mars’ lack of magnetic field contributed to its loss of atmosphere.
Is the expansion of space accelerating? If so, could it someday exceed the speed of light? What would happen then? Find out when astrophysicist Neil deGrasse Tyson and comic co-host Eugene Mirman answer a fan’s Cosmic Query in this StarTalk Radio “Behind the Scenes” video.
