5.4 × 10 83 Qs (1.7 × 10 106 years): The approximate lifespan of a supermassive black hole with a mass of 20 trillion solar masses [21] 10 10 10 76.66 {\displaystyle 10^{10^{10^{76.66}}}} Qs: The scale of an estimated Poincaré recurrence time for the quantum state of a hypothetical box containing an isolated black hole of stellar mass [ 22 ...
1 microsecond – protein folding takes place on the order of microseconds (thus this is the speed of carbon-based life). 1.8 microseconds – the amount of time subtracted from the Earth's day as a result of the 2011 Japanese earthquake. [1] 2 microseconds – the lifetime of a muonium particle.
This timeline of the Big Bang shows a sequence of events as currently theorized. It is a logarithmic scale that shows 10 ⋅ log 10 {\displaystyle 10\cdot \log _{10}} second instead of second . For example, one microsecond is 10 ⋅ log 10 0.000001 = 10 ⋅ ( − 6 ) = − 60 {\displaystyle 10\cdot \log _{10}0.000001=10\cdot (-6)=-60} .
0.01 d (1 % of a day) 14.4 minutes, or 864 seconds. One-hundredth of a day is 1 cd (centiday), also called "kè" in tradidional Chinese timekeeping. The unit was also proposed by Lagrange and endorsed by Rey-Pailhade [5] in the 19th century, named "centijours" (from French centi-'hundred' and jour 'day'). kilosecond: 10 3 s: About 17 minutes ...
A timeline is a list of events displayed in chronological order. [1] It is typically a graphic design showing a long bar labelled with dates paralleling it, and usually contemporaneous events. Timelines can use any suitable scale representing time, suiting the subject and data; many use a linear scale, in which a unit of distance is equal to a ...
A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.

One kè was usually defined as 1 ⁄ 100 of a day until 1628, though there were short periods before then where days had 96, 108 or 120 kè. [7] A kè is about 14.4 minutes, or 14 minutes 24 seconds. In the 19th century, Joseph Charles François de Rey-Pailhade endorsed Lagrange’s proposal of using centijours, but abbreviated cé , and ...
