All concrete collapsing, massive drops/increases in pressure that can shatter your eardrums, untreated metals cold welding, full UV rays going through an Ozone layer that no longer exists, planes fall out of the sky... oh and yeah the Earths mantle just fucking collapsing in on itself and essentially dissolving as its composition has an enormous amount of oxygen

Do you mean every atom of oxygen or just the oxygen in the air? The scenario will be very very different.

  1. Only air O2 is missing for 5 seasons: I think the consequences are pretty minor. There will be no difference in air pressure if the gas mixture is the same everywhere which can be assumed. The lack of oxygen is not problematic for humans and all animals if I'm not missing something. The radiation poisoning without atmosphere is unpleasant but five seconds are not enough to cause long term damage. The plains and birds will see a 20% drop in pressure but aerodynamics is not my field of expertise so I don't know how bad that is.

  2. All Oxygen is gone for five seconds: apocalypse but you won't notice because your body just lost most of its mass and all of its functions in an instant.

Yeah, I suppose all the water everywhere just be hydrogen. I wonder if this would make us all explode, since H2 is gaseous at room temp. Also get a little heat as it goes from atomic to molecular hydrogen.

I suppose it depends on what happens to the lipids that form our cell membranes, whether we explode or just kinda dissolve and fall apart. I'm thinking dissolve now, kinda like a Thanos snap, just leaving behind something like soot.

It wouldn't explode, you need an oxidizer for that. But yeah, we would all dissolve into a pile of goo, since the lipid bilayer of the cells would lose their hydrophile component, probably leading to something similar to soapification, and even if that doesn't kill us, our DNA would degrade in an instant, since oxygen is the binding element between the phosphor atoms which hold the nucleotides together.

Explode doesn't imply combustion...

you are right of course, my hollywood damaged brain made the shortcut from explosion to combustion so naturally that i didn't even realize i added an step lol
