In other words, a LOT.
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.
Max Planck was a full professor at the University of Berlin when he noted that black body radiation could be easily explained if one assumed that light could only exist in discrete "chunks" equal in energy to a constant times the frequency of that light. At the time he published his work, and for many years afterwards, Planck felt it was only a mathematical curiosity; it was only later that he concluded that these quanta (later called photons) were a real, physical entity.
The fastest unit of time measurement is Planck time, which is the time it takes for light to travel one Planck length in a vacuum, approximately 5.39 x 10^-44 seconds. It is considered to be the smallest meaningful unit of time in physics.
Currently, the Planck length is believed to be the smallest meaningful unit of length in physics. It is thought to represent the scale at which classical notions of spacetime cease to be valid, and quantum effects dominate. However, due to the limitations of our current understanding of physics at such small scales, it is uncertain if anything smaller than the Planck length exists.
For a young and healthy human; 20000 times per second.
One second contains approximately ( 5.39 \times 10^{42} ) Planck times. The Planck time, which is about ( 5.39 \times 10^{-44} ) seconds, is the time it takes for light to travel one Planck length. Therefore, when you divide one second by the duration of a Planck time, you arrive at this vast number.
There are one quindecillion (10^48) yoctoseconds in a yottasecond.
Planck's Constant is dimensionally equal to Angular Momentum. The unit is Joules second.
Max Planck had four children.
1059 (1E+59), there are 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 Planck Lengths in a Yottameter.
Many arxiv papers state that the Planck length is the smallest argue convincingly that lengths below the Planck length cannot be measured.
Planck discovered the energy for electromagnetic waves to be Energy=hf. The energy is Planck's Constant times the frequency of the wave.
between 15 and 20 times a second.

a femto second is 1000 times smaller 10-15 an atto second is 1000000 times smaller 10-18 According to current thinking, one Planck time = 5.39 * 10-44 seconds is the smallest unit of time that it will ever be possible to measure.
The smallest unit of time is a Planck Time. It is approximately 5.39124 x 10^-44 second.
