Well your density has certainly increased!

Or perhaps it is because you are trying to have an argument on a subject in which you clearly have no knowledge or understanding whatsoever?

Still trying to come to terms with him going faster than the speed of sound and his microphone not catching what he was saying because he was travelling beyond Mach I. Amazing!

Say what you like ...

There. In black and white. read the whole thread again...

And you replied (to my musings) with this nonsense:

Yes, that was a bugger for everybody that flew on Concorde too...

You then went on to say:

there was no atmosphere that could have supported 'sound'.

Which is why I told you that his helmet contained oxygen and was therefore not a vacuum.

The Concorde comment was perfectly valid (not nonsense) given your inability to understand the consequences of travelling faster than the speed of sound...

I was trying to explain to you, in simple terms that you might understand that it is perfectly possible to travel faster than the speed of sound and still be heard.

And reference my comment regarding the vacuum - you have deliberately misquoted it as you well know. here, I'll quote it in full: -

My point was that 'the speed of sound' is somewhat meaningless as it changes with altitude (and temperature I think) and there was no atmosphere that could have supported 'sound'.

You do yourself no favours by trying to conceal your ignorance in this way....

[Get Real!]

Yes, I for one am bound to lose much sleep tonight over the idiot's exact speed!

Right. Let's attack this from another angle.

The speed of sound is not a constant (as is the speed of light, supposedly). Sound is dependent on the atmosphere it interacts with. So, if the atmosphere and all its contents are travelling at a set speed because they are in an enclosed system, then the soundwaves impacting on that atmosphere (from someone speaking) would still be impacting on the contents of that atmosphere and still be creating sound. The external atmosphere (vacuum or not) would not be affecting the internal atmosphere moving around, at whatever speed, in the (perfectly) enclosed system and hence, irrespective of the speed of external factors, would not now be interacting with any soundwaves generated in the enclosed system forsooth to change their speed and whether they are detected or not by microphones or human ears.

Can some physicist, please, explain to me what is wrong with the above?

I'm not sure if you meant this as a serious reply or if a cat has wandered across your keyboard....?

If it was a serious reply, you appear to be arguing with yourself... I'm not sure what you are trying to achieve with this meaningless ramble...?

The bottom line is that you couldn't get your head around somebody being able to be heard while travelling faster than the speed of sound. I pointed out that they could.

I repeat again (because you really are hard of understanding this week) that the only reference that was made to a vacuum was to explain the speed that Felix achieved.

You can blabber on, miss-quote and obfuscate as much as you like but it won't change the above facts which are clear in this thread for everybody to read and check.

I'd suggest you don't keep replying to this thread which only keeps it at the top of 'recent Topics' and furthers your embarrassment.

Better to let it slip away into obscurity and hope that everybody forgets about it... Concentrate on keeping your bizarre, bigoted opinions about Greece on the top of the pile eh...?

[GreekIslandGirl]

... I'm not sure what you are trying to achieve ...

Correct. Thank you for your efforts, but why don't you let someone less clueless than yourself answer?

The problem is that I don't know the question - and I don't think you do either....

You just seem to keep blabbering on about vacuums and sound transfer therein - which has never been in question...

[GreekIslandGirl]

The problem is that I don't know the question ...

Correct. You lack experience on 'examination'.

Dismissed!

Miss-quoting again...?

You missed out the bit about you not knowing the question either...

What is the question that you are flailing around trying to find the answer for?
