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.
