Glad to hear that...since you apparently can't read very well for understanding anyway: > You're right, Mike: Sound really *does* travel through space. I never said that. If you think I did, please quote where you think that was. Outer Space is not a perfect vacuum (closer in space even less so)...if it was, the Bussard Ramjet would be total fantasy, and the guy who was doing studies of shockwave propagation in intersteller media (resulting from large explosions, such as nova and supernova events) out at NRL about 20 years ago would have been wasting his time. The density is very low (perhaps as low as one hydrogen atom per liter), and in space no-one can hear you mumble, but that doesn't mean that with enough speed you won't notice it, or that if you move fast enough you can't collect a fair bit of mass ahead of you, or that if that mass impacts on your hull at very high speeds it won't transfer enough kinetic energy to cause compression waves in the air inside and make eardrums signal an event...unless you've done the math to show that this can't happen? -- Mike B. -- Mind like a steel trap: once it closes, nothing gets in!
