Did We End The Universe Prematurely By Observing It?


Short answer: no, this is just technobabble.

Less short answer: outside of sci-fi, quantum "observations" have nothing to do with whether a human brain perceives them, and humans are very unlikely to have produced any kind of particle/force interaction so novel to the universe that it creates a species of quantum wavefunction collapse that hasn't happened trillions of times before.

There's about a million fictional allusions to this idea, perhaps best exemplified by a line from an Aeon Flux episode: "Light, in the absence of eyes, illuminates nothing." It's fun idea and a great plot device, but unserious.

Here's the classic "quantum observation" experiment. Note that the results have nothing to do with whether a human happens to be standing there watching it.
