The law of truly large numbers (a statistical adage), attributed to Persi Diaconis and Frederick Mosteller, states that with a large enough number of independent samples, any highly implausible (i.e. unlikely in any single sample, but with constant probability strictly greater than 0 in any sample) result is likely to be observed.

The Rare Earth hypothesis uses the Goldilocks principle in the argument that a planet must be neither too far away from nor too close to a star and galactic centre to support life, while either extreme would result in a planet incapable of supporting life. [6] Such a planet is colloquially called a "Goldilocks Planet".
