It blew my mind when I discovered the mitochondria was once a different organism we just absorbed forever

I’m not going to pretend I’m an expert on pressurization but I am an airline pilot and our charts agree with Wikipedia that it’s about 6-9 seconds of useful consciousness.

I assumed that was obvious. I should know better.

I think it is important to mention it is a VERY BAD thing for a fetus to develop outside of the uterus.

There are interviews about it.

I just want to do my own further research. Do you have a source? Thank you 😊

That's not what happens in real life. Vacuum will fuck with your bodily fluids, causing bruising and bleeding, but it won't explode out of you. The human body is actually pretty good at containing pressure.

The water wouldn't freeze very quickly at all.
Vacuum isn't cold, it has an absence of temperature. There is nothing for the water to transfer its heat to directly, so it would only cool by radiation, which is slow.

Explosive decompression really isn't a thing. You need pressure differentials much higher than one atm to cause that sort of force.
Air isn't sucked out of you instantaneously, that's not how fluid dynamics work, you'd need a much higher differential for it.
Estimates generally give about 15-30 seconds before loss of consciousness, depending on how oxygenated your blood is.

You generally have about three minutes before brain damage due to oxygen deprivation.
You'll also not lose consciousness that quickly. Most estimates give up to 30 seconds, which will depend on how oxygenated your blood is at the time.

Yes, but boiling does not mean hot. It would be boiling at the same temperature, or cooler, as it was before the suit was opened

A large portion of our DNA is endogenous retroviruses, and it increase from say fish-amphibiam-lizard/snake-bird/dinasour(probably)-mammal-placental mammal-primate-human. It helps reshuffle DNA and insceases errors and mutations, which requires the development of better DNA repair functions to survive and increases the speed with which new adaptations emerge. Which is why say an alligator or a bird is pretty close to it's relatively distant ancestry and we're pretty different then our relatively close ancestry, with adaptations such as increase salt intake and decreased water requirements compared to chimps and banobos, nerve activated water grip mode for our digits, more efficient sweating for heat reduction and our very high endurance and more efficient bipedal walking, jogging and running.

The part I don't understand is they keep holding off on making more for some nebulous future project.

Or a fraternal twin situation where one twin is a normal, healthy, viable fetus and the other twin is a complete mole which turned cancerous (called a choriocarcinoma). This is a fast-growing, aggressive cancer that quickly spreads beyond the uterus, particularly to the lungs. The very first thing that needs to be done to treat it is to evacuate the contents of the uterus, and that means terminating the healthy fetus. And there are so many places in the US where that wouldn't happen. She'd just have to wonder if the growing mass would kill the fetus in time for her to get treatment and start chemotherapy, or if it would be too late. But as long as that fetus had a heartbeat, its life would be prioritized higher than hers.
