The birthday paradox seems relevant here as well: With 23 people, your chance of having a "collision" in birthdays is over 50%. With more objects in the sky, the chance of collision is likely greater than one would assume given the space they have to occupy.
- pastel8739 1y agoThough the birthday paradox is concerned with self-collisions, I think since these are explicitly collisions with other objects it feels less paradoxical to compute
- moralestapia 1y agoIt still applies. The classic scenario involves birthdays, a one-dimensional space that closes in itself; while this one is a three-dimensional space that is closed on two of them. Airborne objects also move so I don't know if that decreases or increases the probability of collisions, I guess it depends on how much correlation there is between their movements. It sounds like a fascinating thing to study!
