Does Wolfram believe in supersymmetry? Do the particles mass vary or are they exactly the same all the time? Gravitational mass always the same in the history of the universe? Is the inertia mass always the same, how does that work? What is category theory? Is it possible to make a lens/ camera for wifi? What would differ from a regular cmos digital camera. Can there be a 'pinhole' wifi camera? What would happen if you live streamed a video from a vessel that is going near the speed of light? Would it be slowed down? What's up with the muons discovered?

What is beta decay? I'm confused about the mass of quarks inside of protons/neutrons, somewhere I saw numbers of only a few electrons and the rest is binding energy? Do you think you'll be able to wirelessly "charge" your house in your lifetime? [like Tesla's wireless electricity experiment but practical] Didn't Tesla invent wireless electricity? Does solar count as wireless charging? Can human electro magnetic field interfere with electricity? What is something you have recently changed your perspective or opinion about? "I've answered why there is something instead of nothing, tune in next week" View Less »

What are the biggest differences you notice about how physicists think vs. how mathematicians think? A typical text file is a few KB, a typical audio file is a few MB, a typical video file is a few GB. What would a typical file size be for smell, taste and touch? Is there a reason why a quantitative change leads to a qualitative change? Do you think there is a market for small rockets in Europe? Would those LEO satellites block out sunlight? If we keep getting more precision with atomic clocks, can we use a set of well placed atomic clocks to use gravity's effects on time to create a 3D map of some region of space (say to spy in a room, or see into the ground) to make out things with a centimeter feature?

Is there any experiment in computation similar to Miller - Urey experiment? Can there be life inside a solid? Will it be possible in the future to create an atmosphere on a planetary scale? Why can electromagnetic waves transfer in space while sound waves can't? Could the physics project predict a phenomenon that can't be observed by humans but would be "faster than light"? What about low frequency electromagnetic waves from giant electromagnets ULF could they be sent and detected like from giant coils? Do you think AI based government and regulation of economy will be a reality in this century? View Less »

When an electron moves from one energy level to another and it releases a photon, is the direction of the photon random? Can you please explain inertial and non-inertial reference frames? What are their implications? Why do humans have an appendix even though it is unnecessary? Why do we have folds in our ears? Why do we have folds in our ears? View Less »

Why does Occam's razor work? Stephen, do you know how to cook? How would you explain the goal of your physics project to a 5 year old? Yuval recently indicated that the next pandemic (crisis) will be an attack on the internet. What do you think? What did you think about that strange shaped asteroid passing the solar system, which caused speculation it was an interstellar voyager? Going back to the original thoughts of the "net" but based on new but now almost existing tech/Software? The important part of the attack on the Iranian Uranium system was that it was done through the electric grid and not the "internetgrid". Explaining how that is relevant and possible would be enlightening to many. That can be made a mainly physics answer. In the Wikipedia article for Outmuamua they say "it did exhibit non‑gravitational acceleration" - what does that mean? View Less »
