Question on #physics, specifically Einstein's equivalence principle that you can't tell if you're in a 1g gravitational field or undergoing 1g acceleration in a rocket or similar:
1: Most rocket accelerations etc are linear. Hold your arms out and drop two coins, they land *directly* "beneath" your hands.
2: You can't have a perfectly linear gravitational field, as far as I know? Drop two coins on Earth, they both land *slightly* closer to your feet because it's a radial field.
