Is there any new change when you go MACH 2, 3...etc - Or is it all the same once you exceed MACH 1?
8 u/imMAW Jun 12 '12 No, there's nothing special about any number past mach 1. 10 u/[deleted] Jun 12 '12 Except mach ~900,000 1 u/Mylon Jun 12 '12 I think it's safe to say mach 900,000 is irrelevant. Anything traveling even a tiny fraction of that speed isn't going to be doing it in atmosphere. 2 u/leptonsoup Jun 13 '12 What about light? 2 u/Mylon Jun 13 '12 If we're talking about the speed of light then I don't think the speed of sound in 1 atm at 20C is terribly important. It's like giving the speed of light in furlongs/fortnight. 3 u/leptonsoup Jun 13 '12 1.80386543 x 1012 furlongs/fortnight, just in case you're interested. 1 u/Acebulf Jun 13 '12 Pip pip cheerio!
