Stephen Wolfram answers audience questions about science fiction concepts as part of an unscripted livestream series.

Questions include: How long before we colonize Mars? - Why isn't a Tricorder available yet? - How would teleportation work if we could make it happen? - Why don't we have flying cars yet? - Can you explain the physical difference between a 1 volt and a 2 volt battery? - Can we manipulate the weather and formation of clouds in quantum state or create new kind of quantum equipment? - Is there any merit to discussion about such questions, given that actualization of our sci-fi dreams is never literal? - What are your thoughts on starshot projects that will attempt shooting satellites to the Alpha Centauri system with lasers? - Could a technologically advanced civilization arise on a planet completely covered in water? - Can a tardigrade survive on Mars? - Why aren't prehistoric animals resurrected yet? - Can you engineer a seed to grow a house?
