Before a nanosecond, the next smaller unit of time is a picosecond, which is one trillionth of a second (10^-12 seconds). Following that, there is a femtosecond, which is one quadrillionth of a second (10^-15 seconds). These units are often used in fields like physics and chemistry to measure extremely fast processes.
