Unstable isotopes Memes

The number 0.000000000000000000000866 seconds is precisely the half-life of Hydrogen-5, one of the most unstable isotopes known to science. Turn your back for a fraction of a nanosecond and—poof—half your sample's gone. That side-eye from the dog perfectly captures the existential disappointment of nuclear physicists everywhere. You spend months setting up your experiment, blink once, and your research subject has already transformed into something else entirely. Just another day in isotope studies where your specimens have the staying power of free pizza in a graduate student lounge.
