Great question! There is no scientific consensus on a specific end date for the world. However, a 1960 population study by Heinz von Foerster mathematically projected that human population growth would approach infinity on November 13, 2026 - but this was a symbolic warning about unsustainable growth, not a literal prediction of doom. Current UN projections suggest global population will peak in the 2080s. For Earth's ultimate end, scientific models suggest in about 1 billion years, increasing solar radiation will make the planet uninhabitable as oceans evaporate and oxygen disappears from the atmosphere.
