In the case of the Earth, this means you are repulsed toward the Earth by the weight of the column of space "above" you, and are only prevented from falling through the Earth by its density. The Earth is relatively equally displaced by the column surrounding it, meaning you do not notice this effect.
Gravity seems to come in waves because all things in the relevant column are moving, but the shifting of mass is almost unimportant to your perception because it is such a small value. The magnitude and frequency is such that it goes unnoticed to all but the most sensitive equipment.
.... completely no evidence available, but, it sounds kind of reasonable.

It doesn't make sense when you don't need an answer at that time. If you can find evidence, you should.
After a bit of classroom discussion, from which I abstained, the professor threw the book in the trash (clang! it was a metal trashcan) and gave a speech about how the analysis was gibberish, and how you can't just make up stuff about what a story says. He then walked us through how you might actually obtain useful insights about what the story means to say. It was apparent he gave that spiel every semester.
I'm glad I stayed; it was a good class.

There's an anecdote about a professor telling his students on the first day of a Psychology class, "some things about this field are obvious common sense — for instance, a baby won't recognize and prefer more attractive people as they're unaware of beauty standards."
The class all agrees, and the professor says "JK, babies actually do! Welcome to Psychology."
