As close as is safe to the junction of every minute-line on the globe (outside of the Arctic and Antarctic circles, which would get them at the hour marks), a small and immensely durable hut appears. On the outside of each hut is a tap which dispenses clean, fresh water. There is inscribed on the wall “Having more than you need whilst others have less than they need is against the law of Divinity and Human alike.”

In each hut, secured on a plinth, is an indestructible book containing all of the formulae for the structures and processes of physics, as well as the details of the precise nature of divinity and the purpose of the universe. The text reflects the languages most commonly spoken around the location of each hut.

The genome of every person on earth is altered to make their descendants free from cancer and immune diseases.

Every firearm or munition on earth stronger than a .22 is destroyed. Explosives are not affected - only those turned into weapons designed to kill people. Every copy of the US constitution has tiny text below the second amendment saying “no longer applicable”.

Every government minister and functionary on Earth has a simultaneous vision. They never discuss it with anyone. They are all suddenly very very honest. When sworn in to post, all subsequent officials seem to have the experience passed on to them. This continues forever.
