I can't find anything to back this, but I think his suit was damaged.

... he was travelling so fast because he was in a virtual vacuum where there can be no sound anyway.....

You mean "no friction" from air resistance to affect his speed, right? Because as far as the sound is concerned, he wasn't in a vacuum because he had a helmet on for oxygen!

Anyway, the suit he was wearing must have been slightly permeable or become damaged because his visor fogged up and he couldn't see the instruments. Even though the instruments would have been in front of the visor?

Right... he was in a vacuum which meant there was no wind resistance which meant he fell at whatever speed it was... It also meant that he had no control over his attitude and could not remain stable as he could lower down...

He did of course have oxygen in his helmet otherwise he would have died.

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'.

As for his visor, they had problems with the visor heating before he even left the capsule - as the rabbit says, the visor would therefore have been very cold and his breath would have frosted on it...

His suit would not have been permeable or all the oxygen in it would have escaped into the vacuum and it would not have inflated when they de-pressurised the capsule.

OK?

Don't worry, we're used to you posting things that you can't back up....

The visor would have been very cold, so the water vapour in his breath would have condensed when it touched it.

But there shouldn't have been a temperature change within his suit which would allow condensation to happen, surely?

It's like when the windscreen in your car steams up.

I have never seen her post a car!

There was "atmosphere" in his suit which would support sound waves. That's why they could hear him for most of the time.

Do you even read what people post on here...?

Of course there was 'atmosphere' (air) in his suit otherwise he would have been dead...

The point is that going beyond 'the speed of sound' does not limit in any way, shape or form the ability to communicate... Something that you claimed to be unable to understand in your OP.

I'm sorry, is this the five minute argument or the full half-hour....?

Do you? since I already informed you of that fact!

Right... he was in a vacuum ...

No he was NOT! He had oxygen in his helmet. So HE was not in a vacuum as regards him generating sound - speaking. Which is what we are discussing as emanating from his mouth - soundwaves - and passing down a microphone through oxygen and not a vacuum. Or was his mouth in a vacuum? Along with your brain.

You're being exceptionally obtuse today....

We started this argument because you couldn't get your head around the concept of the speed of sound....

You clearly thought that it would be impossible to be heard because he was travelling faster than the speed of sound...

Now that it has been pointed out to you that the speed of sound has no baring whatsoever on the ability to hear him you have gone off on this bizarre tangent about the atmosphere in his suit...

To reiterate:

The one and only reason vacuum was mentioned was in relation to the reason why he could fall so quickly. In a vacuum, with no air resistance he fell faster than at lower altitudes when the increasing air pressure (the increasing density of the atmosphere) slowed him down.

I did not claim that his suit contained a vacuum. On the contrary, I pointed out quite clearly that had it done so he would have been dead. I also pointed out that if the suit had been ruptured as you claimed he would also have been dead.

OK?

No, I was questioning why we lost sound (couldn't hear him speak through the microphone) around the time they were saying he was reaching the speed of sound.

Not quite right. Try an explain the sonic boom effect and then you might have an inkling of where I was going.

Now that it has been pointed out to you that the speed of sound has no baring whatsoever on the ability to hear him you have gone off on this bizarre tangent about the atmosphere in his suit...

This is complete nonsense. I was talking about his internal environment the whole time. He wasn't SHOUTING the information out into space, was he?

To reiterate:

I'm the one who told you about the air resistance affecting his speed and nothing to do with the internal environment where the soundwaves of him speaking were being generated!

I did not claim that his suit contained a vacuum. On the contrary, I pointed out quite clearly that had it done so he would have been dead. I also pointed out that if the suit had been ruptured as you claimed he would also have been dead.

I had to point it out to you that he had oxygen in his mask. I didn't say the suit was ruptured, but possibly damaged since it was misting up his visor. Something which should NOT have happened. Or do astronauts go around with little wipers inside theirs?

OK?

No. The density has suddenly increased in here today.
