A fan asks why wasn’t there enough pressure to create elements heavier than hydrogen and helium in whatever started the Big Bang? As Neil deGrasse Tyson explains to comic co-host Chuck Nice, the answer lies in the rapid expansion and temperature of the early universe. Neil talks about how stars create heavier elements, and why we have such high confidence in our understanding of conditions after the Big Bang.

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.

While covering the Orion launch for StarTalk Radio, our Social Media Coordinator Stacey Severn interviewed NASA astronaut Cady Coleman and asked her questions provided by our fans on Facebook. Cady discusses the role astronauts have in planning missions to the ISS and the Orion test flight, the biggest hurdle to establishing a permanent human presence in space, long term effect of zero gravity on astronauts, going to Mars, and what can be learned by playing with your food in micro-gravity.

What would our own personal timelines look like if we could step out of the dimension of time and look at our lives the way we currently look at our location in physical space? Find out in this video from Business Insider, when StarTalk Radio host Neil deGrasse Tyson discusses time, time travel, higher dimensions and how they’re depicted in the movie “Interstellar.” *Spoiler alert!*

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.
