In fact, I think they should have one person whose job is cleaning. I think It should be me. Free space rides, amazing photographs, and all the Tang you can drink. Do they still have Tang? If not, I wont go. now the maid has other duties too and u do not want to go there, neither do the astronauts. ---

Also assume that i’m inside a sphere that is surrounded by a vacume. where does teh sound energy go? \*\* If you were in the vacuum there would be no sound energy, since there’d be no air in your lungs to move your vocal chords. Assuming you had managed to get into the vacuum with full lungs (I don’t know whether you’d be strong enough to hold the air inside you without it being sucked out anyway), then the energy would be dispersed with your breath - agitated molecules of air would radiate outwards from you and bounce off the sides of the chamber. It wouldn’t be very loud. ---

I think the soudwaves would be absorbed by the wall material, and your body. Probably pretty loud for a bit though.
