An attosecond (abbreviated as as) is a unit of time in the International System of Units (SI) equal to 10 −18 or 1 ⁄ 1 000 000 000 000 000 000 (one quintillionth) of a second. [ 1 ] An attosecond is to a second, as a second is to approximately 31.69 billion years.

A femtosecond is a unit of time in the International System of Units (SI) equal to 10 −15 or 1 ⁄ 1 000 000 000 000 000 of a second; that is, one quadrillionth, or one millionth of one billionth, of a second. [1] A femtosecond is to a second, as a second is to approximately 31.69 million years.

A man was killed by police after they say he fatally shot his wife and their 2-year-old daughter, and also injured their two other children, in Louisiana.
Their tests involved tunneling electrons, where the group argued a relativistic prediction for tunneling time should be 500–600 attoseconds (an attosecond is one quintillionth (10 −18) of a second). All that could be measured was 24 attoseconds, which is the limit of the test accuracy.
