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

Questions include: What is dark matter? - Why is the Sun's corona hotter than its core? - Are white holes only theoretical or are they real? Is a black hole a sphere with condensed light and matter? or does all that light and matter go somewhere? - A question from 8 years old boy from Houston enjoying this stream but can't stop himself from asking: is it possible now to clone a dinosaur (given that proper quality DNA material will be found)? - How can we tell the difference between science and pseudoscience? - In convection, what drives the flow of air/fluid in the first place? is it just the potential energy stored in the temperature gradient? - Is there any possibility of creation of dark matter in fusion reactors like tokomak? - Why is the moon the same size as the sun? [from what we see on Earth] - What do you do for fun?
