Q&A 114: Why Isn't There A Microscope On Mars? And More... Featuring Stella Kafka from AAVSO

In this week's questions show, I explain why it doesn't make sense to send a microscope to Mars, how we could use a black hole to see a reflection of Earth and see dinosaurs, and why we don't just send a solar sail down to the Sun. Featuring Stella Kafka from the American Association of Variable Star Observers https://www.aavso.org/ 00:42 Why no microscopes to Mars? 02:38 Could we see a reflection of Earth? 04:37 Send a solar sail to the Sun? 07:03 How will red dwarfs die? 08:51 Do radio telescopes have pixels? 10:58 Do aliens have to be close to detect us? 13:21 Will civilizations want to settle every star? 15:17 What is expanding in between space? 17:18 Will we get out of balance with nature? 21:42 Do black holes come in different shapes? 24:03 How could a civilization go extinct? 26:37 Are there models for dying stars?
