most solids and liquids are practically incompressible (when comparing with gasses). there is a relationship between bulk compressibility, shear stress and youngs modulus for solids, which can be extended for liquids. It does not work for gasses

Along with the people pointing out conductivity.
Who says water is not compressible? Takes a lot of energy, but the big bang didn’t happen in a sea of water.

My oceanography textbook said so. You’d think the ocean people knew about water. Must be more propaganda from big compress to sell more compression.

To be fair, ive seen what the ocean can do to carbon fiber tubes. If it can do that and still not compress, its pretty damn incompressible.

Yeah, it’s been 15 years since I’ve taken oceanography, but the density of water is determined by its temperature.
Gradually_Adjusting@lemmy.world 5 days ago
Density is certainly changeable in water with temperature, but density isn’t exactly the same thing as compression.
TIL A waterjet cutter pressurizes the water to something like 90,000 psi and it gets about 14% more dense. I always thought those things just had the water highly pressurised, but not actually compressed.

I want to posit that because water isn’t compressible at forces we experience commonly, it doesn’t mean it isn’t compressible. For 99.999% of the water rules we concern ourselves with water should be considered incompressible, but there are exceptions to every rule
