Nobel Prize for physics goes for creating attosecond pulses of light.
There's the same number of attoseconds in 1 second as there are seconds in the age of the universe. Crazy.
'The Royal Swedish Academy of Sciences has awarded the 2023 Nobel Prize in Physics to three scientists who used ultrafast pulses of light to do just that with a technique known as attosecond spectroscopy. Per the citation, Pierre Agostini, Ferenc Krausz, and Anne L'Huillier "have given humanity new tools for exploring the world of electrons inside atoms."'
