1. 1 Easy

   Which subatomic particle is nicknamed the God particle?

   Answer: Higgs boson

   Why: Leon Lederman wanted to call his 1993 book The Goddamn Particle, citing the particle's villainous nature and cost, but his publisher refused.

2. 2 Medium

   Which element has the lowest boiling point of all substances?

   Answer: helium

   Why: It boils at 4.222 kelvin and is the only element that will not freeze solid at atmospheric pressure however cold it gets.

3. 3 Hard

   How fast does a spinning black hole's ergosphere drag spacetime?

   Answer: Faster than light

   Why: Locally nothing outruns light, but seen from far away the ergosphere sweeps spacetime past light speed, so no object there can hover still.

4. 4 Easy

   Which physical constant represents the smallest possible unit of action?

   Answer: Planck constant

   Why: Its value is now fixed exactly by definition, and since 2019 the kilogram itself has been defined from it.

5. 5 Medium

   Which type of radiation has the highest energy and frequency?

   Answer: Gamma rays

   Why: Thunderstorms make gamma rays too: about a thousand times a day they flash out some of the highest-energy light found naturally on Earth.

6. 6 Hard

   Relativity makes GPS satellite clocks gain how many microseconds a day?

   Answer: 38

   Why: Weak gravity gains 45 microseconds a day, orbital speed loses 7; leave the 38 net uncorrected and GPS fixes drift about 10 km per day.
