Gravity is completely dominated by other forces, to such a degree that it seems plausible to me that an essentially indistinguishable pebble could exist in a universe with a very different gravity law
Doesn’t this depend heavily upon the sensitivity and discrimination of our observing phenomena, as well as whether we examine the pebble as a static, frozen moment or as a phenomenon occurring in time?
For the pebble to truly be completely identical, you might need for it to be embedded in a completely identical cosmos. How small does the difference have to be before it distinguishes one from the other, and do the effects of any one thing on the rest of the cosmos (and vice versa) ever drop to nothing?
