Science & Technology Q&A for Kids (and others) [Part 129]

Stephen Wolfram hosts a live and unscripted Ask Me Anything about the history of science and technology for all ages. Find the playlist of Q&A's here: https://wolfr.am/youtube-sw-qa Originally livestreamed at: https://twitch.tv/stephen_wolfram If you missed the original livestream of this episode, feel free to submit a question you would like Stephen to answer in a future Q&A livestream here: https://wolfr.am/12cczmv5J 00:00 Start stream 00:58 SW starts talking 1:11-32:59 Why is it important that the periodic table is structured as a table rather than a list of elements? 33:11-51:55 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. 51:59-1:11:28 How certain are we that the Big Bang actually happened? What are the chances of the Big Bang theory being displaced in the future? 1:11:37-1:14:32 What do you make of the very early galaxies seen by JWST, which seem too large to exist so early? 1:14:42-1:17:54 Is it possible that the expansion of space due to dark energy could eventually be fast enough that even atoms and nuclei come apart? 1:18:03-1:22:19 How is the temperature of cosmic background radiation measured? Is it just from the wavelength of the microwaves? Follow us on our official social media channels.
