they practice space walks in a swimming pool
cause that is where their space walks will actually take place
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
