in theory, how much force would it take to compress say 1,000 cubic metres of water into 10 cubic metres.
what changes would happen to the water?

You can't compress a liquid unless you heat it and turn it into a gas.

then you wouldn't be compressing a liquid.

the answer is a fuck of a lot.
it would probably become quite viscous

what started happening to the universe after the big bang?

As a chemical engineer speaking, you are wrong.
You can compress a liquid, but we're talking very minimal changes. No where near the amount that is being asked in this thread.
edit: the answer to the question though: more than is humanly possible

Google "allotropic ice"
Thank you, Kurt Vonnegut! :P

Yea, I know that you can compress it a tiny little bit, but I felt that saying that you can't compress it is enough without elaborating.

Don't make false statements cause you're too lazy to write 2 more sentences.

i've been on that page already.
came across this as well,
Hot ice
Hot ice is the name given to another surprising phenomenon in which water at room temperature can be turned into ice that remains at room temperature by supplying an electric field of the order of 106 volts per meter.[4]
weird science.

I think in theory you could compress it to the density of a neutron star.

You could, but then it wouldn't be water anymore. I believe he was making that distinction.

Why must divers come back up to the surface slowly and why do submarines have crush depth ratings if liquids can't be compressed?

yeah but the density change in comparison is minimal

Divers need to come to the surface slowly so they don't get the bends. This is from gases in the body forming bubbles in the blood and has nothing to do with compression of liquid.
Actually, both result from pressure and have nothing to do with incompressibility :icon32:

I remember reading somewhere an interesting fact about the universe. The amount of space between matter is so great, that if all the matter in the (visible) universe were squeezed together as tightly as possible (to the planck level), it would take up less space than the nucleus of an atom.
