Fixed errors
[edit]The original reference link was dead, and some of the numbers and dates used based on that reference link were wrong. Using two new references, I fixed the dates and removed the dead link. Additionally, I cleaned up the writing a little bit. On the 82.2 seconds of human history figure, I used the conversion rate from the KGS of 146 calendar seconds per year for about 12,000 years (comes out to 12001.2). I hope that doesn't count as "original research", as I wanted maintain some of the previous editor's writing on that.
Arithmetic check
[edit]"A third analogy...includes the Earth's future, leading up to the Sun's death in the next 5 billion years. As a result, each month now represents 1 of 12 billion years of the Earth's life. According to this calendar, the first life appears in January, and the first animals first appeared in May, with the present day taking place on May 18. Even though the Sun won't destroy Earth until December 31, all animals will die out by the end of May."
Unless I've missed my mark, a not rare occurrence, something's either not clearly written or not right in the arithmetic. If "today" we are in the month of May, per this geologic calendar, we have another 7 months until the end of the "year" - and the end of the Earth. But the Sun dies in the next 5 billion years, i.e. within the "month" of May, since each "month" represents 12 billion years. The Earth is supposed to carry on without a sun in its solar system?
