So called fat tailed distributions are a random walk. It’s just that their sample distribution is a power law (no mean hence fat tail). Example of which is a Lévy flight: a random walk with a heavy tail.
That’s not at all why drugs work quickly through the nose - it has absolutely nothing to do with nerve endings, it has everything to do with a large surface area of mucus membranes allowing quick uptake into the venous system.
apparently, turkeys have a pretty understandable language. There's a documentary, My Life as a Turkey [1]; he was able to decipher what each call meant (e.g. which squawk meant "snake" and which one meant "eagle"). So, if you were walking with a turkey, and you saw a snake and wanted to warn it about it, you could, in theory, communicate with it.
Yep any size particle should. But gravity is described by classical physics through general relativity. When you have situations of very small quantum scales and large gravitational fields both general relativity and quantum field theory don’t work well together. This is a big problem in physics.

This company did a slight pivot to building autonomous collectors anchored in rivers which have the most plastic dumped into them leading to the ocean.
