As promised...we've got something new next week!

Mike is back after spending the last couple months at different jobs. Have you ever found a fossil? Do you know where your checked bag disappears to at the airport? We'll even put on a beekeeper suit! 

Look for the first two episodes next Thursday.

For our finale episode Mike gets perspective from a guest who's been somewhere that most of us will never get to go: space!

Commander Chris Hadfield is a retired astronaut who flew two Space Shuttle missions and also served as commander of the International Space Station. 

They're just like any other bill! Yet, they feel like a novelty. What makes them feel so special? 

Mike learns more about the curious currency from John Bennardo, who made a documentary on the $2 bill, and Heather McCabe who completed a project called, "Two Buckaroo," where she documented the reaction to spending them. 

You can check out John's film at 2dollarbillmovie.com

Remember Concorde? The supersonic passenger airliner from Air France and British Airways that flew twice the speed of sound? Its been retired nearly twenty years now, but there hasn't been anything like it since.

Three former British Airways pilots, Andy Mills, Richard Westray, and Mike Bannister, tell us what it was like to fly the thing!

Why are there so many stories about creature, places, and things we can't prove are real? 

Colin Dickey, cultural historian and author of "The Unidentified: Mythical Monsters, Alien Encounters, and Our Obsession with the Unexplained," explains our fascination with the unexplainable. 

What is time? Why do we have it? How come we're so bad at comprehending how it passes? Does time fly? If you're bored, does it slow down?

Sean Carroll at Johns Hopkins University, author of "The Biggest Ideas in the Universe: Space, Time, and Motion," spends some time answering Mikes big questions. 

And what about boredom and downtime? James Danckert, author of "Out of My Skull: The Psychology of Boredom," and Dr. Sandi Mann, author of "The Upside of Downtime," explain the two.

This week, we've got some listener questions!

How are flyovers at big events timed so perfectly? Captain Kyle Cassady, a B-2 Pilot at Whiteman AFB, tells Mike how they pull it off. 

We heard elephants are afraid of mice... Is that true? Patrick Wolff at Oakland Zoo answers.

And we talk with Hillary Clinton, Jennifer Coolidge and Cher! No. We talk to Rosemary Watson who is a singer, emcee and impressionist. How do people learn to do other people's voices?

Time to go back in time! You know that insult when we call someone "a Neanderthal" …does that really work? Were they actually dumb, or do they deserve some credit?

Anthropology professor and Neanderthal expert, Fred Smith, tells us just how close of cousins we are to them.

We're also going to travel into the future...with a company that's working on bringing a Wooly Mammoth (among other things) back from extinction. Ben Lamm, is co-founder and CEO of Colossal and, Dr. Andrew Pask, is a Professor in the School of BioSciences at the University of Melbourne, explain just how that could work.

Time to expand our minds a bit and tackle a big one. And it probably comes as no surprise that it's incredibly hard to describe "being you." 

Sue Blackmore, writer, lecturer and Professor at the University of Plymouth and 
Anil Seth, Professor at the University of Sussex and author of "Being You: A New Science of Consciousness," explain what there is to know about consciousness.

How can we get a feel for what colorblind people see? Marie Difolco with Colour Blind Awareness in the UK gives Mike an idea of the colorblind experience.

And, how do you gauge a "chance of rain" in the weather report? Alex Tardy, Warning Coordination Meteorologist at the National Weather Service in San Diego, explains what's known as one of meteorology's most misunderstood terms.
