Why do you think God created the universe to look so old
if it’s only something like 10,000 years old at most?
Objective
Tonight’s Homework
To see timescales for the
universe in a scale that makes
a bit more sense
Finish your calendar by Friday
Cosmic Calendar
It’s hard to get a sense
for just how long the
history of the universe
is. For the rest of today
and tomorrow you’re
going to work with your
friends to create a
cosmic calendar. This
calendar will compress
the whole history of the
Universe down to just
365 days, like the one
shown at right. On your
calendar, make
December big since
most events in the
relative history of the
universe have only
happened very recently.
