Itching, faraday cages, mermaids  

Is there a way i can prove the earth is spinning? Where would a helium balloon go in space? Can you eat spider venom?

Stomach butterflies, baby hair, making gold

Human superpowers, remembering dreams, asdteroids  

Is it possible for humans to have superpowers? Should we just let asteroids hit the earth so we can make use of the precious elements they contain? Why do I always wake up before reaching my destination?

Multiverses, string theory, global consciousness  

Professor Brian Greene, Theoretical Physicist and String Theorist from Columbia University joins Dr Karl and Zan to answer all your multiverse and string theory questions.

Seeing the same colours, downward bubbles, space elevators  

Dr Karl and Zan are joined by Bubble Physicist Dr Helen Czersky to answer your questions like: why stout bubbles go down, whether or not we'll ever see space elevators and whether we all see the same colours.

Spaghettification, multiverses, the end of space  

Dr Karl and Zan are joined by Astrophysicist Professor Lisa Harvey-Smith to answer your star based questions like: Where does space end? Is it possible there are multiple universes? What is Spaghettification?
