Science & Technology Q&A for Kids & Others:
Does gravity's strength cause a fundamental limit for the size a planet? What about a star? What about a black hole? What about a galaxy? What about the universe? Internal gas pressure and gravity are two main forces for star formation from nebulas. What was the pressure of the early universe vs. today? Just as a thought experiment. Can one stretch a vacuum beyond a "breaking point" similar to how matter can be compressed beyond a "breaking point" that leads to black holes? In both quantum field theory and general relativity, the zero-point energy seems to be arbitrary: you can add a constant to the equations and it will still be a valid solution. But in general relativity there seems to be a notion of absolute energy because of its gravitational effects. This zero point seems to be associated with flat space. Why is flat space non-gravitational, i.e. why is flat space the lowest possible energy state? Any ideas about "hacking nature" to gain powers (get infinite energy, travel faster than light, etc.). Do you think all these are possible at all? Can we really "hack" or "alter" the rules of nature? You can travel faster than light if the space between you and your destination changes; this happens quite frequently as the universe expands, and it's why we get measurements faster than the speed of light in space. It's just a fabrication. This brings up a related question. You cannot distinguish the geometry of empty space from that which has matter that is uniformly distributed. So it is perhaps uniformity that determines the geometry (without dark energy). But this assumes matter can be spread out like a fluid, instead of being discrete. So perhaps flat space is indeed the lowest-energy state. Uniform matter cannot exist because of the discreteness of matter, which leads inevitably to inhomogeneities. It's almost like you need to solve the puzzle of constructing the space you want to travel through before you can travel through it. Why is the refractive index for x-rays into matter smaller than 1? Does that mean that the speed of light for x-rays is faster in matter than in a vacuum? View Less »

Business, Innovation & Managing Life Q&A:
How do you prepare for your keynote talks about new technologies and Wolfram Language features? What barriers currently still exist that keep AR/VR from being widely useful in the workplace? One thing I genuinely appreciate about Stephen is his obvious incredible delight when explaining concepts, particularly related to science. Does he ever have to force it? Do you take part in clinical trials? Diagnosing is definitely a potential job for AI. Can Wolfram Language screen for diseases or illnesses? ​Is it possible to change human DNA by intention, I mean by eating foods or taking medicine? Do you try to convince your children to go to specific universities/schools, or do they decide by themselves without any impact from you? Multiple screens are nice, but I feel it's less productive sometimes. Sort of the same thing as multitasking being a myth. I feel like I am someone who has a lot of interests. I did my engineering degree a decade ago but I want to study mathematics, physics, philosophy and neuroscience too. Have you also been someone with diverse interests? If so, how do you manage them? I feel like I struggle with wanting to learn so much more—I feel like it's a lot better to be focused and simple-minded. Any tips for fixing a chaotic filesystem? My files are scattered everywhere. What do you do when you feel like you're stuck in the mud and can't get out? How do you write? How much do you use the mouse while writing in a notebook? Do you have any preferences in reading hard copy vs. digital? You should have an automatic email word cloud generator. Does UV hurt the paper? Physical books are heavy and bulky, while ebooks are never bigger than your favorite tablet! What is the oldest book you own? Do you think storage devices like tapes and punch cards might come back sometime? View Less »
