with divers pretending to be in space

and thats a vasume over his entiure body not just a small hole

a small hole to a perfect vacume is not that dangerious

vacuums are extremely powerful

they can be yes

they work the opposite of water

they can be extremely dangerous

a vacume is a lack of pressure

like water

go deep enough you have massive amounts of water on you piling on you

with a vacuum its the opposite

pushing

with a vacume its not exactly opposite but a lack of pressure

a vacume is relative

its a lower pressure

a pure vacume is zero pressure

the stronger the vacuum the more stuff wants to fill it

yes

a perfect vacume vs sea level pressure will be 14 psi of air pressure trying to push you thru the small hole

thats tiny

barely any force

altho yes the water on the surface of your skin does boil

keep in mind that in the vacuum of space, if it was real, would be much stronger than this example

false

not much stronger

that almost near perfect vacume

well even if it was half of sea level

a pure vacume will only doubble the force

notice that pressure = force per area

thats a large area on that cylendar

large area = large force

small area = small force

yes

even space isn't a perfect vacuum

yes

if it actually exists, which it doesn't

but its damn near close to it
