Picture of the day
If you knock on the door, and you're in a vacuum, does it make a sound?
Well, inside the space station, it does. Unless, of course, the airlock has been bled of air. Then . . . no.
Assuming the vibration doesn't travel past the airlock. If it did . . . probably.
Unless, of course, nobody was in a position to hear it. In that case, does it still make a sound?
Audio at 11. Or not.
Reporting from space . . . well, not actually from space . . . more like the voiceover booth at the end of the hall . . . well, not exactly at the end of the hall, more like just before you get to the end of the hall . . . Hank Kimball, Eyewitness News.
