Daniel and Kelly’s Extraordinary Universe Listener Questions #34
6 snips
Mar 31, 2026 They unpack why morning fog forms, exploring condensation, dew point, and the conditions that make mist cling to low ground. They tackle animal balance and circulation by asking whether bats and geckos get dizzy and what prevents blood pooling. They dive into exotic spacetime: Cauchy horizons, light cones, and why rotating black holes challenge predictability.

Why Morning Fog Forms
- Fog forms when air cools below its dew point and water vapor condenses into tiny droplets visible as fog.
- Clear nights, light winds, nearby water or recent rain make cooling effective so moist air reaches saturation and produces morning fog.
How To Spot Foggy Morning Conditions
- To predict morning fog, look for recent rain or nearby water, clear nights, light winds, and cool ground.
- Those conditions let warm moist air cool efficiently to the dew point so condensation (fog) appears by morning.
Dew Reveals Tiny Morning Worlds
- Kelly Weinersmith loves walking hay fields at dawn to see dew-highlighted spider webs and tiny morning worlds invisible later in the day.
- She compares that micro-universe to discovering features you miss at everyday scales.
