    Halley’s Comet only happens every 76 years? Wording could be better there. Halley’s Comet can only be seen every 76 because that’s when it passes earth. That doesn’t mean it ceases to exist during the rest of the time.

    @Pelahnar Unless you believe in the quantum mechanical principle that something only exists when it’s observed (to be fair, astronomers can observe both the comet and its gravitational effects even when it’s not visible to the unaided eye)
