/sci/ - Science & Math

hey sci, i'm currently writing physic engine and i just figured that i don't know how impulses in uncompressable liquid work.

say we have 1000 km undeformable pipe, closed at one end and filled with uncompressable liquid. now we apply pressure to liquid at open end, and what exactly happens? i take it impulse travels in liquid somehow, no?

The UFO phenomena is ultimately social psychosis(it's like witches and succubus from dark ages), and old guy from oppic is just that- old mad man. Besides, we can't find any evidences of trans-galactic civilization, and that probably means Great Filter. I assume that Great Filter is simple realization, that our so called "sentience" is just chemical process in brain. It deems all struggle senseless and crushes civilization. We will be able to watch the results here on earth with neuroscience progress.

There aren't any highly developed lifeforms out there, guys.
