​​Could the expansion of the universe affect biological evolution? ​How much does the sky weigh? How much does the Earth weigh? What would happen if gravity on Earth changed to that of the Moon? What if gravity suddenly got stronger? So a full data memory card vs. a new, empty data memory card of the same kind: will there be a slight difference in weight due to the data filled? Do insects (e.g. ants, mites, etc.)/bacteria have brains? Assuming they do, do they have emotions? Do they feel pain? If they (in the case of bacteria) don't have a brain, what governs their behaviors? How was it discovered that caffeine could energize us? Is it all living things that experience these effects, or is it exclusive to humans? If electronics have coils and the brain has coils, should we be more conscious of signals in the air? Is there a reason for the food likes and dislikes that each person experiences? Can tastebuds be tricked? View Less »

​Is it possible to create more universe? Why does running my Waterpik interrupt Bluetooth connections? In third grade, I had an argument with a teacher. She said, "Before humans had language, they thought just like us." I argued that couldn't be true—instead, language gave way to complex thoughts. Was I right? Why do many medications have side effects? Why do we yawn? Are yawns truly contagious? Why do cats meow, why do dogs bark, why do birds chirp? Why can't AI help us to analyze animal sounds? Do photons run through antimatter? Does that make them matter? Is chemistry really just physics? Does brain size have any correlation to IQ? Well, the hardware of the brain is an ongoing process, especially in childhood. Nurture, environmental, social and natural circumstances can cause changes in brain hardware. Do bigger brains actually have more functional neurons, or are they just more spread out? Would all whales speak the same whale language? A friend had a bird that learned to imitate their microwave alarm. View Less »

Why is it important that the periodic table is structured as a table rather than a list of elements? Is the periodic table just the table for the current state? Since there weren't heavy atoms from the start (Big Bang), maybe in the far future everything decays and just the electrons survive. How certain are we that the Big Bang actually happened? What are the chances of the Big Bang theory being displaced in the future? What do you make of the very early galaxies seen by JWST, which seem too large to exist so early? Is it possible that the expansion of space due to dark energy could eventually be fast enough that even atoms and nuclei come apart? How is the temperature of cosmic background radiation measured? Is it just from the wavelength of the microwaves? View Less »

Congrats on the new blog post! Are there any dangers to these "custom" plugins? Allowing ChatGPT access to your computer seems like asking for an AI takeover. Is current tech like ChatGPT going to be able to answer every question imaginable? Are you worried about being replaced by AI? A caveat, though: LLMs can quite easily be asked to write in any nonperfect way we want! What are some ways LLMs can be improved? Do these improvements require advancements in technology that haven't yet been made? One thing that worries me about LLM is that right now, many people are using LLM as a "source of truth" or even "references" to their arguments. Perhaps the only real way for an AI to make those value judgments is for it to be able to model its own possible future states and decide for itself? Asking for ChatGPT to write less formally makes me think of the evolution of music genres, i.e. electronic music is now "not perfect" on purpose. We're gonna one day find out that these livestreams are like a really advanced Turing test being conducted at Wolfram, and both Stephen and the moderators in the chat have been AIs all along.

In quantum chromodynamics, what is color confinement? How did we discover strong nuclear force? Is there a finite number of sub-atomic particles? Or will we forever find new unique ones? How do detectors sense the presence of these particles? For example, if a microphone has a diaphragm detecting vibrating air, what is the diaphragm of this detector? View Less »

If you ask the AI the exact same question several times, will it give the same answer or will it change it based on some random function? Or do the neurons change during self-learning and change the answer? Do you think at any point we will create an AI factory? Like specialized AI algorithms that create other AIs (which can do very well one specific task)? Any thoughts on using physics simulations vs. the real world to teach robots? Is it computer power then that speeds real progress? What do you think about sources of energy now and in the future for developed and developing countries? What will happen when oil runs out? Will there be a shift to "clean" energy well before this happens? For nuclear energy, do the dangers pose a problem? Or do the pros outweigh the cons in this situation? Apparently the death rate for nuclear energy is around 0.04 deaths per terawatt-hour, which is similar to wind and solar. Nuclear is safer than coal, because people are more cautious when the stakes are higher. What do you think of small modular reactors? What is the connection between computational irreducibility and extracting usable energy? Can energy be "mined" with computation? Nuclear is not going to be a good thing until we have some way of dealing with the waste products. View Less »
