On Earth, much of the wrenching discomfort of emesis, apart from the sensation of nausea itself, is from the coordination of many muscles it takes to counter gravity.

Earth gravity and a line of horizon is how we, as Earth humans, are accustomed to gauging spatial orientation.
Vanna Bonta
But to return to Kepler, his great sagacity, and continual meditation on the planetary motions, suggested to him some views of the true principles from which these motions flow. In his preface to the commentaries concerning the planet Mars, he speaks of gravity as of a power that was mutual betwixt bodies, and tells us that the earth and moon tend towards each other, and would meet in a point so many times nearer to the earth than to the moon, as the earth is greater than the moon, if their motions did not hinder it. He adds that the tides arise from the gravity of the waters towards the moon. But not having just enough notions of the laws of motion, he does not seem to have been able to make the best use of these thoughts; nor does he appear to have adhered to them steadily, since in his epitome of astronomy, published eleven years after, he proposes a physical account of the planetary motions, derived from different principles.
Johannes Kepler
Gravity is a mutual affection between cognate bodies towards union or conjunction (similar in kind to the magnetic virtue), so that the earth attracts a stone much rather than the stone seeks the earth.
Johannes Kepler
Quaking muscles in the act of birth,
Between her legs a pigmy face appear,
And the first murderer lay upon the earth.A. D. Hope
Sometimes I think I would love to see … just to see the beauty of flowers and trees and birds and the earth and grass. … Being as I've never seen, I don't know what it's like to see. So in a sense I'm complete. Maybe I'd be incomplete if I did see. Maybe I'd see some things that I didn't want to see . . . the beauty of the earth compared to the destruction of man. You see, it's one thing when you are blind from birth, and you don't know what it's like to see, anyway, so it is just like seeing. The sensation of seeing is not one that I have and not one that I worry about.
