- We humans are so stuck in the middle of the cosmic scales — in average height, one-hundredth of one-septillionth (10^-24) the size of the observable universe, and with typical life spans of a couple octillion attoseconds. And an attosecond is an eternity compared with the lifetime of the elusive Higgs boson, a subatomic particle that exists for one-thousandth of an attosecond before decaying.2023 October 9, Dennis Overbye, “The Science Nobel Winners Were Short and Fast”, in The New York Times, archived from the original on 12 Oct 2023:
