Pressure is from anything with weight applying a force, so an atmosphere has a certain amount of pressure depending on the volume and mass of the atmosphere, right. And in space there is no pressure or atmosphere and the no pressure is why you practically explode if unprotected, your cells pop and it is nasty. So every time in a show the atmosphere is vented in a ship, the people in the room should practically explode right, why and if not, explain please.

I would say in this situation venting the atmosphere would mean venting what we need to survive. Which would be similar to putting a bag over your head and tieing it around the neck. It wouldn't create a vacuum but would remove the air so you can not breath. What you are suggesting is more along the lines of depressurizing or completely exposing to space.Last edited by Jeffer; 07 June 2010, 03:13 PM.Duct tape is like the Force.

The idea of people exploding in a vacuum is a myth. People have survived exposure to extremely low pressure and even vacuums. Animal experiments show that it would take about 90 seconds of exposure to vacuum for it to be fatal.
It would take extremely rapid decompression for the alveoli, eardrums, and sinuses to pop, and the blood vessels to rupture.
