Learning Today: How Long Was A Dinosaur Day?

A day didn't used to be 24 hours. In fact, the rotation of the earth is slowing down. So back in the time of the dinosaurs, a day was only 22 and 1/4 hours.

So if you ever complain about there not being enough hours in a day, your solution is simple: travel back in time.

Found on the ever-enlightening, Dr Karl podcast (MP3 link).

Wouldn't you have to travel FORWARD? travelling back would give you less hours if I understand you correctly!
