Another attosecond; that's how time works.
The metric prefix "atto" means 10^-18. The next smaller prefix, which may be what you meant to ask, would be "zepto" for 10^-21, followed by "yocto" for 10^-24. No smaller prefixes are formally defined, but a "Planck time" is about 5 x 10^-44 seconds, and is believed to be the smallest physically meaningful unit of time.
What else can I help you with?
What comes before an attosecond?
A nanosecond comes before an attosecond and before a nano second is a millisecond and before that is a second
What is an attosecond?
An attosecond is an SI unit of time equal to 10 ^ -18 seconds.
What is less than a femtosecond?
Attosecond
What is smaller than a attosecond?
a zeptosecond
What is a Atto Second?
An attosecond is 1x10-18 seconds
What is equals shorter than a nanosecond?
Examples: -- picosecond -- femtosecond -- yoctosecond -- attosecond
What are the other smaller units of second?
Split second, milli, micro, nano, pico, femto, attosecond etc.
What is an extremely fast unit of time?
An attosecond is an extremely fast unit of time, equal to one quintillionth of a second. It is used to measure processes on the timescale of atomic and subatomic interactions.
What is the scientific prefix of 10 to the negative 18th power?
The prefix that means one quintillionth, or times ten to the negative 18th power, is atto-. Examples: An attometer is a quintillionth of a meter, and an attosecond is a quintillionth of a second.
What is shorter a microsecond or a nanosecond?
An attosecond is one quintillionth (10 to the power of minus 18) of a second. As of 2006, the smallest unit of time that was directly measured was on the order of 1 attosecond (10−18 s), or about 1026 Planck times. In physics, the Planck time, (tP), is the unit of time in the system of natural units known as Planck units. It is the time required for light to travel, in a vacuum, a distance of 1 Planck length. The unit is named after Max Planck, who was the first to propose it.
