Join Robert Ehrlich on a lighthearted romp through the universe and get an intellectually exhilarating introduction to modern physics as you go! From the zany - How long a hot dog would you be? What kind of straws do they use in hell? How much hotter is the bottom of a waterfall than the top? When should you add cream to your coffee? On how big a planet could you hit a baseball into orbit? To the serious - How close could you get to Ground Zero and survive? How long has it been since the last mass extinction? How old is life on earth? How big is the universe? These bite-sized essays and cartoons entertain while they educate you about the sizes of stuff in the universe: how big, how small, how much, how far, how fast, how hot, how old - from the innards of atoms to the farthest quasars. If you ever wondered how fast you'd have to jump to survive in a falling elevator, The Cosmological Milkshake is the book for you!
