That is how hard they make it, they consistently remove evidence about the past. I fight with the conspiracy theorists .... I fight with with people who claim to be scientists, ... When does reality win? I fight with UFO believers...
You fight everybody.
If you had evidence, you would win the fight.
You make absurd claims about science the, when you are called to account, you wander off into nonsense.
You seem unable to understand that you are simply wrong.
How do you explain the observation that you think that science was better years ago- but nobody else thinks that?
If you think you are the only one who is right- well, let's just say there are words for that.
Lastly, I'm not going to let this (repeated) bit of dangerous nonsense pass.
You say"During hydronic pipe freezing operations using very pure liquid CO2, being poured onto a hot water pipe that was leaking, I was in a cloud of CO2 and water vapor for some time with no ill effect."
Well, if there was no air, you would be dead.
Also, liquid CO2 does not exist at atmospheric pressure. your stupidly dangerous claim to have been pouring it is physically impossible.
It's not impurities in the gas that make the difference. It's the volume and how much air it gets mixed with.
Your statement clearly belongs in the "that can't be true" forum.
Others will judge on the issue of who is a fool- but anyone who implies they don't need air to breathe looks that way to me.
You are playing dangerous word games. You claim that my understanding that basic science was better years ago, is only understood by me, and that some large body of amazingly intelligent sorts that account for everyone else do not feel that way. Well if this large body of geniuses exist they should try building something of quality. Or some of the things we built in the 50's.
As far as needing a medium to remove carbonic acid from your lungs you certainly do. As far as needing 21 percent oxygen, some deep sea sub experiments put that into serious question.
Cowardice and intelligence are on two different ends of the spectrum.
