Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series, also available on YouTube here: https://wolfr.am/youtube-sw-qa

Questions include: Can you explain neutrino messaging and whether it's feasible to build a neutrino messaging system or neutrino internet? - Is the results we see in particle physics valid even outside our gravitational field? The elementary particles we discover in our accelerators, could they be bounded to the physics we see at earth. Other "things?" produced in space? - Why should gravity, which is considered to be a very weak force compared to the others, have any significant effect on high energy particle physics experiments? -I have a question relating to thermodynamics. How could we detect and remove the impact of Refrigeration and Air Conditioning indoors on outdoor global temperature, significant? - Can we build a giant magnifying glass and put it in orbit to create a death ray? - A related question does a magnifying glass steal energy from the surrounding? - Can you name any technologies that were fragile and unreliable 50 to 100 years ago but are extremely reliable and widely used now? Are there any early-stage fragile technologies today that have the potential to be widely used 50 years later? -Is there anything that is the opposite? Something that is fragile today that was stable a century ago. Does technology universally get better always? - What will be the next advancement in microprocessors? 3D lithography?
