 Scientist turns around to the Virtuous Pupil for a possible answer, but all he receives is the usual blank look. So he turns back to the table and resumes, "This 'around'! Because if you have a time machine and you want to witness the impact, you don't know the exact date and hour of the impact. You don't know if it was 80,436,239 years ago or 79,734,127 years ago. So, the only way for you to witness it is to go back exactly eighty-million years ago, check for missing dinos, and then do another jump in time, forward or backward, looking for the recent signs of an asteroid impact. And you keep doing these smaller and smaller jumps for shorter and shorter periods, closing in every time on the impact event and checking each time: 'Dinos? No? Jump back! Dinos? Yes? Jump forward!' until you are lucky to find that special day. Then you take a spot with a nice view near the future crater and wait the entire day."

"Wait the entire day," the Virtuous Pupil repeats. "Got it!"

The Master Scientist turns around to see if the kitty was paying attention or is just repeating the last words.

"The same problem presents itself with the extinction of humans. We know an extinction happened 'around' ten-million years ago. We know it happened extremely fast, but we don't know the exact date. Some of the professors love the dramatic idea of a cataclysmic, flash extinction, while most of the realistic ones prefer the idea of a long extinction spread over a couple of centuries. But the problem remains the same: the 'around factor!

"Because the distance in time is so long, we don't know the precise time when the extinction started and when it ended; otherwise, we would send you straight to that date. So, you will have to jump forward and backward in time until you will find the period of the extinction."

"Jump forward and backward. Got it!"

The Master Scientist is becoming annoyed by these last words repeats—and his squinty eyes are showing it fully.
