Time log of the happenings in the Universe,
from the Big Bang birth, to now, and onward to the predicted Dilute Death.
Clock - To cover a wide range in time, a 'logarithmic clock' will be used.
In this clock we measure 'log(time)', which is the normal (base 10)
LOGARITHM OF THE TIME IN YEARS SINCE THE BIG BANG.
Examples:
time ............................................N = log(time in years)
10 000 years =104 years =10N years where N=4, hence clock tick N =4 =log(10 000 years)
1000 years =103 years =10N years where N=3, hence clock tick N =3 =log(1000 years)
0.01 year =10-2 year =10N years where N=-2, hence clock tick N =-2 =log(0.01 year)
After each clock tick, the Universe is 10 times older than the previous tick.
Clock range: N=log(time)= -60 to -35 <--distant past
Clock range: N=log(time)= -35 to -10
Clock range: N=log(time)= -10 to +15
Clock range: N=log(time)= +15 to +40
Clock range: N=log(time)= +40 to +65
Clock range: N=log(time)= +65 to +90
Clock range: N=log(time)= +90 to +115 <--distant future
