@Chaj23 asked the Naked Scientists:
   
Wacky Q: space being a vacuum if a giant pipeline were constructed opening in space & on ground would the atmo be depleted?

What do you think?

NO

The pressure inside the pipe would be essentially the same as the pressure outside the pipe, and the air inside the pipe would behave identically to the air outside of the pipe.
