        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.
