And vice versa! The more you try to compress water, the closer you "push" it towards 3.98 centigrade. That's why water stays liquid below a certain depth, for example in the sea. Without that fact, water would freeze at higher pressures and no life would have developed in the ocean depths.
- Traubenfuchs 2y agoWhat does that mean for extreme environments like… a black hole? Water gets sucked in, experiences ultimate gravity and compression bringing it close to stopped time… at almost perfect 3.98?
- remuskaos 2y agoWell, no, for more than one reason. First, for the water, time doesn't stop. Chances are it wouldn't even know it surpassed the event horizon (you know, if it could actually experience anything). For an external observer, it would crawl to a halt just outside the event horizon until it simply fades from vision. Then gravitational tidal forces aren't strictly a uniform compression, on the contrary. Since gravity increases by 1/r^2, the part of the water drop that's closest to the black hole would experience largest force. That tears everything apart, so the water would be more dispersed instead of compressed. While I haven't done the math (and don't know if I even still could), I'd assume that gravity would quickly overcome Van Der Waals forces that holds the water molecules together, so it'd probably closer to water vapour than liquid. And lastly, once it finally reaches the singularity, all bets are off. As far as I'm aware we have no idea what happens to matter in a singularity apart from contributing to its mass.
