Bishop James Ussher's estimate
age of the universe/creation, the beginning of time, as the night
preceding 23 October 4004 BC, according to the proleptic Julian
calendar. The speaker will not make fun of this serious Christian
scholarly estimate as is generally done now by the theologically
ignorant see http://en.wikipedia.org/wiki/James_Ussher. Come and celebrate creation day.
Galileo Galilei (see URL: http://en.wikipedia.org/wiki/Galileo) estimate of at least 20 million years
based upon fossils wood and fossil ammonites in Italy. Leonardo da Vinci discovery of mollusk
on the top of Tuscany mountains for another earlier age of the
earth estimate see URL: http://en.wikipedia.org/wiki/Leonardo_da_Vinci. The current best estimate of the age of
the universe, the dawn of time, of 13.75±0.11 Gyr (billion
years). What does this mean given that the earth, our
reference frame did not even exist during creation, and that the
proper time of a photon, particle of light is zero? The PowerPoint
used during the show in 2014.
