To Get an Understanding of the Speed of Earth's Rotation

"One second after the sun sets where you are, the sun will set
approximately two blocks away. So, nightfall is moving at about two blocks
per second or 750 miles per hour, which is just about the speed of sound."

At the North·Pole, 6 months pass before night returns.
Night “falls� at zero miles per hour.

It's actually a tad faster than the speed of sound ... that's why
no one has ever heard the Sun farting ....

In Equador, it's a lot faster and straight down. Compared to other
latitudes, there's a saying "the sun doesn't set, it crashes."

Wow. They take a statement that may be true for a specific latitude
at a specific time of year, and extrapolate it into something glaringly
inaccurate, where nightfall only moves at 75% of the speed at which
Earth rotates. Impressive.

I never thought of it like that. I will have to work that into a
conversation in the next week. Thanks.
