Can virus or bacteria survive a PPO2 over 30?

As for decompression, it seems quite likely that bacterial cells would undergo explosive decompression. I wonder about viruses though. A typical bacterial cell is in the range of 2-5 microns long. A corona virus is in the range of 0.125 microns. I wonder if this size would render it too small for bubble development?

Maybe, but that is still nearly unimaginably larger than Nitrogen and Oxygen molecules. I can design a pressure vessel with a tiny port for a microscope if anyone can get a grant.

True, unless you suffer from isolation-induced intellectual curiosity.

We were recently discussing the physics of long-lamented beer bong festivities and college-borne inner ear games, where:

Δy = v0 sinθ t – 1/2gt2²

Where y = -1.0 m, v0 is initial velocity; v0sinθ is the initial velocity component in the vertical, θ is the initial, eh, 30 degree angle of launch, g is the acceleration due to gravity (-9.8m/s2²) and t is the period of travel.

Ahhh, the covidiocy . . .

Thanks, it's been a while; thought I forgot something, from all of the dissipation . . .

Like someone said sometime, if I were out of gas, I'd suck a donkey's behind if I thought it'd give me the gas I needed to survive.

I am so stealing this!!!

Indeed it is, but the nuclei or nanobubbles required for bubble formation are probably half the size, or more, of the virus itself. Of course there is still a lot we don't understand about this, but it's fun to think about. I'd love to see the pressure vessel!

I doubt that bubble formation is a factor. The effect of explosive decompression is just that, explosive. Hyperbaric docs have used terms like hamburger and gruesome to describe the victims of pressure vessel failures during sat dives. Thankfully I've never seen it. Space between molecules relative to pressure is a constant.

Depends on how deep I am and how close to NDL. Could be I would make an attempt at CESA first

I'm a KISS kinda guy. Gas? Go for it, no matter how. No gas? Get the eff out of Dodge one way or another.

When we talk about tissues in multicellular beings, or even single cellular, the physics can start to be very different relative to things (viruses) that are barely bigger than bubble nucleation substrates. For perspective, a typical human cell is 100 microns, bacterial cell is 3 microns, and a virus is .15 microns. But indeed, I'm speculating. As I mentioned before, I would expect that the high oxidative environment would be at least as detrimental to bacteria and viruses prior to decompression.
