It's pretty bad. Someone on a recent "space" thread remarked that he was afraid that Voyager 3(?) was going to puncture the heliosphere. I'm almost completely sure he was joking, but my first reaction was "like worrying about it will make a difference." [chuckle]
Me, I don't know what the big deal is anyway.. I have more important things to worry about Pluto (Like I was going to visit there in the first place)...
I know a guy who swears up and down that the space shuttle pokes holes in the atmosphere on every launch. I tried to explain it to him by dropping a rock in the lake and asking him to find the hole be he couldn't grasp the similarities between air and water.
He gets mad because I walk behind him and act like I'm choking from walking in the hole he makes when he walks.
