There's No Such Thing as Gravity--The Earth Sucks

by: William C. Robertson, Ph.D.

What happens when you drop an object on the ground? Though it might not be obvious, the object speeds up as it falls. That means it's accelerating and there must be a force acting on it. The force that's acting on it is--all together now--gravity. In this chapter, you will learn that the only force acting all the time is gravity.
