False. I said you can’t go below absolute vacuum. My post talked explicitly about going below ambient air pressure to create a relative (not an absolute) vacuum.

Source? (Absent a source, I’m guessing that should be 29.99 inHg, not PSI.)

False let me explain..
The atmospheric pressure at see level is 14.7 PSI.. so going by what he said you would not be able to go beyond zero PSI but we know you can go to at least -29.99 PSI so if you take away 14.7 PSI there is 15.29 PSI that would be below what he claims you can not go beyond..
I believe you are mixing non-interchangeable units again. Atmospheric pressure of 14.7 PSI is 29.92 inHg. You could reduce an atmospheric pressure of 14.7 PSI by nearly 14.7 PSI. You could reduce an atmospheric pressure of 29.92 inHg by nearly 29.92 inHg. Without a source, I have no reason to believe your unsubstantiated assertion that the lowest vacuum ever measured was 29.99 PSI.
Here’s an example from a source you love: Wikipedia! ""Below atmospheric" means that the absolute pressure is equal to the current atmospheric pressure (e.g. 29.92 inHg) minus the vacuum pressure in the same units. Thus a vacuum of 26 inHg is equivalent to an absolute pressure of 4 inHg (29.92 inHg - 26 inHg)."

Not the same. you do not feel the heat cause it isn’t there but the result of being burned is there..
What is "212%F"?
Again, GSpot, you are mixing different concepts. Of course, as you’ve done this before in the thread, I don’t know whether you are talking about boiling or evaporation. (GSpotMassagerS - A revolutionary theory about blisters)
But let’s break it down one more time. Boiling and burning are two different things. Reduce pressure enough, and you can boil water at temperatures that do not burn or cook. My example of the spacesuit failure is a case in point. If your spacesuit fails in space, your fluids may boil, but your body will not be burned. It’s called ebullism: http://en.wikip … g/wiki/Ebullism .
Hey, and here’s a bonus! Want to know what the pressure is where body fluids boil at body temperature? It’s 6.3 kPa (47 torr). (Note: kPa and torr are not interchangeable with PSI or inHg or mmHg.)
Note that 6.3 kPa compares to a normal atmospheric pressure of 101.325 kPa, so again, that’s a reduction in pressure far beyond the normal pumping vacuum range, once again showing that GSPotMassagerS’s revolutionary theory to be fundamentally flawed.

You’re mixing units again, in any case; PSI is different still from either inHg or mmHg.
