In a New York Zeptosecond

As life speeds up in unprecedented ways, the New York minute is no longer a sufficient descriptor.

Meet the zeptosecond: “the time it takes a light particle to cross a hydrogen molecule.”  This is now “the shortest unit of time ever.” 

To put it in mathematical perspective, a zeptosecond equals “a trillionth of a billionth of a second.”  For those who prefer visuals, it’s “a decimal point followed by 20 zeroes and a 1.”

In any event, it’s fast.  Before you can say “Times Square,” it’s long gone.
