Hi there, everyone! Well, do you know what is 0.000000000000000000247
? If you don't, I will tell you. 0.000000000000000000247 second, also known as 247 zeptoseconds
is the short period of time (it is how long does it takes a single particle of light to pass through a molecule of hydrogen). Physicists have measured the shortest span of time ever. And this is it -- 0.000000000000000000247 second (a.k.a 247 zeptoseconds).
