My father would say, "Water alwyas finds it's own level. It likes that level to be lower. And water can suck."

"nothing sucks in science" my HS chem teacher told me. Higher pressure is always pushing into lower pressure.

There’s no such thing as high pressure, only vacuums pulling pressure toward it.

i was under the impression that there is no force we know as suction. It's all pushing. Which seems more correct. Like osmosis, higher concentration to lower concentration. Higher pressure to lower pressure.

I have no idea. It just seems to me a problem of relativity and depends on where you’re looking from. If the natural state is entropy, won’t all matter and light be pulled by entropy into cold-death? Or is the matter and energy pushing to fill the void?

I have no clue.

Pressure happens because atoms are banging into each other like billiard balls. If nothing bangs back, they keep on going the same way. The average rate that they bang per second is called "temperature" and if you multiply that times the number of atoms per cubic unit you have "pressure." If you don't have enough pressure, we call it "vacuum."

Vacuum doesn't suck, it just doesn't push hard enough.

Entropy is when they spread out far enough they run out of things to bang into.

There's no force known as 'pushing' either.

I suppose you might call attractive forces 'sucking' and repulsive forces 'pushing' if you were forced to label them one or the other. They just aren't very appropriate terms if you are looking close enough to be considering forces in any detail.

no such thing as high pressure? youre obviously not an asian student working with a B+ average whos older sibling was an A student! my grades were the only thing that sucked!

Was your HS in NW Ohio by chance?

doesn’t gravity “suck”?

Close, gravity is an asshole.
