-
The actual process used by the scientists, called attosecond absorption spectroscopy, is about as fiendishly complicated as its name, so let's take this slowly.
-
Through a process called attosecond absorption spectroscopy, researchers were able to time the oscillations between simultaneously produced quantum states of valence electrons with great precision.

If you slowed down time so that an attosecond lasted for 1 second, that second would last for 30 billion years – more than twice the age of the universe.

Faster camera shutters used to be enough, but recently lasers have let physicists break the femto- and attosecond barriers, compressing the temporal resolution of images down to the time it takes light to cross a hydrogen atom.
