Duplicate Universe phenomenon

The Duplicate Universe phenomenon is a phenomenon where an alternate universe like ours exists, but with tiny added changes. Various people began recalling memories of a Plinka, and a person titled "Boyfriend" who ran a country called "Boyfriendpore" despite no person or country existing. While originally observed as a Mandela Effect, it was revealed that an alternate universe does exist with those properties, discovered by the AUFM. Scientists are trying to gain access to such universe, but with no or minor breakthroughs. Currently, 2 hair samples of both entities are being used to construct an identical or near-perfect match to those entities. Along with that, scientists discovered other universes with differing yet similar properties. The Flopsworn are also trying to open a time rift to those dimensions, but with no luck either. The most recent breakthrough was when scientists managed to recover a flooparoid photo of one of the universes. It shows a strange building, named "S ERM KET". The meaning behind it is unknown.
