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: Could we be inside of a black hole? Can biological life survive? - Would something trapped in the liminal space between the event horizon and "singularity" eventually be able to escape? - In a black hole, does time stop? Is this a case for string theory? - What are the implications of a naked black hole (one without an event horizon) on the universe? - It is very interesting that the more the black hole "eats," the larger the surface gets. So what exactly is the singularity? - If matter and antimatter both have positive mass, then wouldn't Hawking radiation increase the mass of a black hole? - How small can a black hole be? "Micro-black holes," maybe? - Do you think it will ever be possible to reproduce a black hole situation in a lab for practical research/experimentation? - What is spinning in a spinning black hole? - Can black holes have a charge? Can the effect of the charge propagate out of the black hole if photons cannot escape? - Why are they named black holes and not after the name of the people who found/discovered this phenomenon? - Could lasers be used to display an advertisement (or perhaps a clock) on the Moon? Can high-bandwidth internet connections be bounced off reflectors on the Moon? - If the Moon is responsible for the tides, can the Earth be responsible for some micro-movement of moon dust? - Buying an ad that burns up upon reentry sounds incredibly wasteful. - Would the tea dumped into Boston Harbor during the Boston Tea Party have affected the underwater ecosystem? - How would biologists test for the effects of caffeine on fish? - Why are the elements on the Earth not more homogeneous? Why are there areas/mines abundant with certain metals? Is the heterogeneity of elements increasing or decreasing on Earth? Is this the same for other planets? Galaxies?
