So many sounds from space are modified in some way e.g. If returned to a normal atmosphere fairly quickly, a person would survive with few if any irreversible injuries after an accidental exposure to vacuum. Unfortunately, those movies and TV shows (and video games) give the wrong impression about what it's like to be in space. This is something that most of us already know. There aren't traditional sound waves—vibrations in a medium like air—in a vacuum, so screaming is probably a waste of breath. their frequencies are brought into the range of human hearing, or they are 'sonifications' of data i.e. A fresh and vacuum unbaked o-ring will contain contaminants trapped within its bulk. The results will surprise and delight! They were in no danger of losing their air right away, but they had to go to some effort to get it plugged safely and permanently. There is a erroneous, but persistent, belief that the N 2 molecules will sorb to the surfaces and thus provide a barrier layer to reduce the sorption of water molecules onto the surface. However, the evaporation process cools down the remaining nitrogen, allowing it to … But as said by @Peter Shor, if you, by some means , could decrease the internal pressure of the bubble to such an extent that it becomes equal to surface tension factor, then the bubble will exist i.e. Achieving extremely high vacuums is tough, as Professor O'Brien points out. You might think that dropping things in a giant vacuum chamber would be the ultimate in coolness. Even at low voltages, electricity can in fact travel through a perfect vacuum.

The unfortunate space traveler wouldn't be able to hold their breath for long (if at all), because it would cause lung damage. There is a great deal of data based on long-duration flights by such astronauts as Mark Kelly and Peggy Whitman, but the life sciences experts at most space agencies need a lot more data to understand what will happen to future travelers. He then turns a valve to seal the disks shut, and now they cannot be … Backfilling a chamber with dry nitrogen (N 2) instead of ambient air is a well known and accepted procedure to produce a faster pumpdown time after opening the chamber. So, if you want your bubble to exist in the chamber, there must be some mechanism to nullify the outward pressure of the bubble; otherwise it'll burst. There's actually evidence for that happening from an astronaut who experienced it.
