Proper & Mark Save the World

Every quantum experiment says you never actually die — you just slide into the universe where you lived. Proper and Mark follow the physics down the rabbit hole: if every choice splits reality, which version of you is reading this right now?

Proper and Mark take on the strangest radio signal ever detected — 72 seconds from deep space in 1977, never repeated, never explained — and why they don't buy the comet story.

Proper and Mark take on the only unsolved skyjacking in American history — the 1971 jump, the riverbank money, the suspects, the tie — and why they're convinced Cooper got away with it.

Proper and Mark launch Proper & Mark Save the World with a full deep dive on the Mandela Effect — the Berenstain Bears, the Monopoly man's monocle, the cornucopia that vanished — and why they don't buy the official explanation.
