Today EVSN look at what tree rings can teach us about past earthquakes, & how well machine learning can identify life, like trees, from carbon-rich materials that were never alive to distant galaxies and spinning black holes. We even take a deep dive into anti-matter.
Is light made of waves or particles? Is matter made of waves or particles? What does it mean for matter to “wave”, anyway?
Why are matter and antimatter symmetric? What happened in the early universe to make matter win? Do we have any clue as to why? What do puppies have to do with it? I discuss these questions and more in today’s Ask a Spaceman!
