From John Marshall
Michael Brooks asks whether we could destroy the fabric of the cosmos (2 May, p 35). Do we have here a solution to Fermi’s paradox concerning the lack of signs of extraterrestrial life?
If measuring and collapsing a fundamental quantum state destroys the measurer, then each civilisation would be the only life form in a universe that should be teeming with life – until they make that fateful measurement.
