Stephen Wolfram Q&A, For Kids (and others) [May 22, 2020]

81 min • 25 september 2020

Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series.

Questions include: How far away are we from a new propulsion system that could take us to another galaxy? - What about a "railgun" in space that also launches rockets? - Micro nuclear explosions? - Does the sun emit EMP pulses, and if so how are satellites protected? - If light is made of light, how can it go around anything? - Can you build a satellite with off the shelf electronics (such as raspberry pi) by providing enough CPU redundancy and some basic shielding? - What additional shielding technologies do you think we need to best overcome space radiation that astronauts face when headed to Mars? - What are the unique properties of element 115? - How do I win the fight against the fear of learning something if it looks really intimidating? - Gravity affects photons but photons have no mass? Or is this a case of energy equals mass?
