Science & Technology Q&A for Kids (and others) [June 9, 2023]

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 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 taste buds be tricked?
