Women gain just as much muscle mass from strength training as men, relative to what they started with. But because they usually start from a much lower baseline, their overall strength will still be lower than that of a comparably trained man.

So you're telling me, if I was loud enough in space I could breathe fire?

So substitute the words "evolved for" for "designed for" and the statement stands.

A black hole has a mass and deforms spacetime, a chair has a mass and deforms spacetime. The chair might have a more complex internal structure (we are not sure, because we can't check for black holes), but why would that be relevant to call it a physical object? A black hole is obviously there in space, so it's a physical object.

I’m a little rusty on this aspect but I’ll try to explain how things work which may help you answer things better for yourself. we have multiple antibody types making up our immune system. Some of these cells are in constant rotation and react to a broad range of things, they are first line of defense. There are also antibodies for specific antigens and these can take time to make, if you’ve never had exposure to a disease it would take the body a little extra time to ramp up and attack. Some immune cells have longer memories and can be stored away in our lymph nodes until needed leading to a faster response.

The stuff we have vaccines for are diseases that our body makes the memory cells for. Viruses like the one that causes flu constantly change their surface proteins over time which is why we need new ones so frequently, we don’t have the cells to fight the new strains. Some infections can completely wipe out immune systems memory leaving us more vulnerable as we have no/limited immune memory and would have to rebuild it.

There is no way to generally enhance, though limiting stress etc will help your cells do their jobs better in mounting a defense.

If you moved that tuning fork directly into a pocket or air, would it produce its tone?

Exactly, evolution doesn't design anything. Natural selection just results in certain traits that lead to survival of the species. In a different environment, humans may have evolved differently.

> I’m assuming you’re also gassing off water vapor and other things into the vacuum from your skin, eyes, mouth, lungs, etc. which would cause a loss in temperature locally I think?

Absolutely. Due to the extremely low pressure in space, any liquid water would immediately evaporate, as the boiling point is inversely related to pressure. This will cause your surface temperature to drop. But as soon as that's over, your core temperature would probably offset that again.

Cold air is a killer of an external combustion system. You want to have the charge air pre heated already so you aren’t using the energy of the fuel to get the air up to combustion temperature and then heat the water.

This is covered in one of our FAQs that no one ever reads.

> an event on such a scale could cause sufficient particulate matter to enter the atmosphere that it could create a period of several years of insufficient sunlight reaching the surface of the earth to massively disrupt ecosystems and create a mass extinction event.

So the potential cooling effects of large explosive volcanic eruptions (e.g., events like the 1815 Mount Tambora eruption) are not disputed, but this is not actually relevant for Deccan Traps volcanism or the suggested kill mechanisms related to them. For the Deccan Traps as the cause of the K-Pg extinction, the kill mechanism may have been global warming from pulses of greenhouse gases released by the volcanism (e.g., Tobin et al., 2012) or a combination of this along with ocean acidification and ocean warming (e.g., Keller et al., 2020). I.e., flood basalt eruption and its effects do not equal large caldera eruption and its effects.

If you were wearing a space suit, you would hear yourself but others wouldn't. If you did not have a space suit, the air would rush out of your lungs the moment you opened your mouth. You might hear your voice up until the moment your lungs were empty (from inside your head), but no one else would.
