Science isn't about doubting all previous results.
If there is an emergent result that challenges previous understandings then that's what you doubt, until more experiments confirm the validity of those results. Once those results are sufficiently confirmed then doubting them becomes silly.

Doubting all previous results impedes progress, so there's no logical reason to do so.

From doing some reading it appears to be so.
The Gemini spacesuit was designed so that the helmet would rotate as the astronaut turned his head because the helmet fitted to the head. Later space suits had larger helmets that allowed the astronauts to wear headsets under them and turn their heads freely in the helmet.

Soda cans are actually have a fairly high internal pressure, so it's quite likely it would explode. See

tires
reading the sidewall of your tire you will notice it says something like max 45 psi or something close enough to that. Atmospheric pressure at sea level is about 15 psi. So if you took a tire inflated to 45 psi into space the 15 psi pushing in would be gone and youd be left with the absolute pressure in the tire relative to the vacuum which is 45+15=60 psi. The tire might pop at that increased pressure. Or you could just inflate it to 30psi (gage pressure) at sea level, so that the absolute pressure relative to the vacuum of space would be 45 psi (absolute pressure) and within the material tolerances so it wouldnt pop.

its not even that different from the pic on the left except instead of bubbles venting into the ocean you have gas venting into space. and instead of a tube pumping air from the surface you have compressed air tanks pushing air into the suit.

Most clearly seen at :49 to :52 seconds, the Gemini helmets did turn when the head turned.

It seems so fucking odd to me that people think a suit with a head that turned is somehow impossible, could not have been real, but NASA would fake one for some reason. That just makes zero sense.
