force, varying directly as the difference in temperature. Space, being a vacuum, lacks heat entirely. Its temperature is that of Absolute Zero.

To state the problem more simply: have you ever watched a pot of beans boil? A seething whirlpool is created; the beans seek the heat." "By golly!" said O'Hara.
