In this week’s Questions and Answers show, I explain how astronauts are trained to deal with medical emergencies if the Universe is expanding smoothly or chaotically, and what would survive longer, a white dwarf or a red dwarf?
01:34 [Tatooine] What if there’s a medical emergency on the ISS?
04:13 [Coruscant] Could we see before the Big Bang?
09:28 [Hoth] Are there stars below the Earth too?
12:22 [Naboo] Is there a way to see something moving faster than light?
15:00 [Kamino] Why is the SLS fuel tank orange?
16:30 [Bespin] Could Titan serve as a fuel depot?
18:19 [Mustafar] Would the expansion of the Universe eventually spaghettify all matter?
21:37 [Alderaan] If you rode a space elevator, wouldn’t you fall back down?
23:36 [Dagobah] What lasts longer, a red dwarf or a white dwarf?
25:44 [Yavin] Would I like a solution to dark matter or dark energy?
26:41 [Mandalore] Why doesn’t the Moon fall down to the Earth?
28:28 [Geonosis] Has anyone actually tried going the speed of light?
29:20 [Corellia] How could we broadcast our existence to aliens?
