With reasonable assumptions about latitude and body shape, how much time might she gain them? Note: whatever the answer, sunrise always comes too soon. (Also, is it worth it if she throws up?

Description

Angular Momentum is the force upon an object having a certain velocity while spinning. You may remember the certain strain when a spinning yoyo returned into your hand, giving it that much "slip" to discomfort you. The energy of that momentum does that. Angular Momentum is also forced upon the Earth, as it is spinning 24 hours a day, 7 days a week. This 24/7 rotation enables us to have a clock. Hence, we say that the Earth is running "clockwise".

In the comic, Megan tries to work against this (massive) energy. She is spinning counter-clockwise, thus generating energy to stop the Earth from moving. It is obvious that she (as one human being) will not succeed in stopping the Earth getting it's cycle, let alone she generates "clockwise" energy from the other half of her spin. But the romance part is also obvious. After all, who wouldn't want to be longer with the one they truly love?

Randall states the obvious in the Image Text: while not being able to reverse time, enjoy your night time. Sunrise comes too early.
