Wouldn't patients lying flat in bed all day experience a similar issue?

What I also don't understand is that E. coli can make you sick if it already lives in your guts. It seems counterintuitive to me that eating your own faeces can make you ill. Even though that's an image I don't want to have on my mind.

>That said, cooking things kills bacteria, so you're not at risk for not deveining.

Then why are slaughterhouses so under scrutiny to prevent fecal contamination?

How can you prove anything is zero? Even for the photon mass the best we have is an upper limit of 10^-18 ev/c^2.

Clearly all the dna of eukaryotes is so related that it cannot be due to chance. But could it be that archae and bacteria formed from separate abiogenesis events?

Or could eukaryotes have formed multiple times? We know that encapsulation of bacteria to form organelles has occurred at least twice, namely for mitochondria and for chloroplasts. Could it be that different eukaryotic kingdoms have mitochondria that are not related?

>If the conditions necessary to spawn life essentially produced a population, rather than an individual, then I don't know that we'd be able to tell the difference without seeing it in action.

Yes this is essentially what I meant, the question whether all life comes from one single cell, of if at some point the conditions were such that many cells formed that were very similar, maybe even with similar dna that was being copied, floating around.

Can't it be that this happened multiple times, but that the resulting biochemistry was so similar that we can't tell? If the ocean was filled with particular building bricks, the optimal results would all look similar right?

I don't know if this completely what you mean, but laser works by stimulated emission of photons, since they like to be in the same quantum state.

OK, but I need 2500 kcal per day to function. If I don't eat carbohydrates, what am I going to replace them with?

Which, even it biologically makes sense, is hypocritical. Can't have one without the other.

Some people think that because of this it is morally worse if women die than men. E.g. when Russia commits terrorist attacks in Ukraine, it is stressed more if women died in the attack.

If a family member is going through a long death bed I sometimes feel relief when they're finally dead. The pain is sharp and intense in that moment. But the months or dread and anticipation can really wear you out.

Survival doesn't mean it is likely to infect. Even if you can demonstrate that the virus stays intact in a dried blood stain, it is extremely unlikely to make it's way into your circulation from there. Since if you touch the dried stain, not much material will stick on your hands, and even if you managed to bring a few virus particles to your mouth by accident, it is not very contagious via the oral route (compared to direct blood contact or vaginal or anal intercourse).

Although is there a practical purpose for this? Only case I can think of where you would intentionally subject humans to more than a few G is in fighter jets. But couldn't we replace those with drones that can make 50 G turns?

Even better, once you take into account time dilation, the distances you can cover with such a manoeuvre in a certain amound of proper tine are equal to the classical calculation. Meaning in 1 human lifetime with 40 years 1G acceleration and then deceleration, you would cover almost 1700 light years in 80 years of proper time. Of course that means everyone you knew on earth is dead.

A neutron bomb is a type of nuclear bomb designed to generate a high neutron flux, rather than a high explosive power. Since neutrons don't carry an electric charge, they can penetrate many materials more effectively than charged particles, which are slowed down by all the electrons. This means a neutron bomb produces a lot of radiation that can effectively penetrate buildings and even tank armour, killing many people from radiation poisoning while creating a relatively small explosive yield. This would make it suitable as a tactical nuclear weapon, meant to eliminate armoured divisions while limiting infrastructural damage.
