As you see from the picture, atoms are mostly empty space.

Yet people say fluids can not be compressed.

How much force would be needed to compress water, and overcome the strong force?

>> No.1316466

Well if nothing (as far as we know) can compress a liquid than wouldn't it make sense that fluid is a force?

>> No.1316470

>fluids can not be compressed

It's an approximation. If fluids really couldn't be compressed, there would be no sound.

>> No.1316946

Mandatory:
I was born in a water moon. Some people, especially its inhabitants, called it a planet, but as it was only a little over two hundred kilometres in diameter, 'moon' seems the more accurate term. The moon was made entirely of water, by which I mean it was a globe that not only had no land, but no rock either, a sphere with no solid core at all, just liquid water, all the way down to the very centre of the globe.

If it had been much bigger the moon would have had a core of ice, for water, though supposedly incompressible, is not entirely so, and will change under extremes of pressure to become ice. (If you are used to living on a planet where ice floats on the surface of water, this seems odd and even wrong, but nevertheless it is the case.) The moon was not quite of a size for an ice core to form, and therefore one could, if one was sufficiently hardy, and adequately proof against the water pressure, make one's way down, through the increasing weight of water above, to the very centre of the moon.

Where a strange thing happened.

For here, at the very centre of this watery globe, there seemed to be no gravity. There was colossal pressure, certainly, pressing in from every side, but one was in effect weightless (on the outside of a planet, moon or other body, watery or not, one is always being pulled towards its centre; once at its centre one is being pulled equally in all directions), and indeed the pressure around one was, for the same reason, not quite as great as one might have expected it to be, given the mass of water that the moon was made up from.

No, it doesn't.

Also a nickle-size is small time. I was bedridden most of last december, the whole of january and half of february because I had a boil the size of my palm and fingers in the middle of my back.
Surgical debridement under local anesthetic was fun.
Less fun was getting my bandages changed daily or two times per day, each time getting a wad of antibacterial tape crammed into the hole in my back so the boil would drain properly. No anesthetic during the cramming, instead a lot of bitemarks on an old belt I started to keep with me for the purpose.

pic related, the boil is well on it's way to healing and the hole left after debridement is almost closed.

Shit that sucks, man! The pain I went through sucked enough.

It didn't hurt like... bad, it felt more like extreme pressure I guess. Wish I wasn't drunk during. I think it decreased my pain threshold.

I had a friend who got a boil on his ass. IMHO, the worst place to get one, because you can't exactly sit on anything else.

It's okay. I have a sense of humour about myself. Part of why the bandage change was so painful was that even with my teeth clenched from pain, I couldn't stop laughing.

the proof of this can be found in coulomb's law , or simply the fact that sound travels trough water , so it must be compressible , else there would be no audible sounds underwater

Every time I laughed during the cramming, I would move a little and the metallic pin they used would scrape along the sides or move the wad of tape around in the hole.

During the two months it took to heal, I wasn't really able to do much else than take my meds and sleep. Not directly because of the boil, but because I was so fucking exhausted after the bandage change.

This question is not as retarded as it seems first. But long before any force compressing the water would be in the order of strong interactions, you would have a few phase changes inbetween

At some point, I guess, the temperature/pressure would be so high to ionize that shit to a plasma.

Well basically if under enough pressure the hydrogen bonds are overcame and the atoms are forced closer together than they noramlly would be.
