If the surface were that hot, would sea creatures still want to live on it? I have no idea what their range of tolerance is, but I'd assume that they're well adapted for living on relatively cool rocks. And if it's not that hot, then it seems like there's not a cooling problem.
(To be clear, I'm speculating without any real knowledge of this subject, and welcome the inevitable corrections.)
- Etheryte 6y agoThe ocean is host to a very wide number of creatures and bacteria, some live in arctic cold waters, others on volcanic vents, and every range in between. There's a good saying for this, roughly translated, that nature doesn't love an empty spot — if one type of plant or bacteria won't live in an area, someone else will quickly settle in.
- shuntress 6y agoI am familiar with that sentiment expressed through the phrase "nature abhors a vacuum"
- smaddox 6y agoThe irony is that this phrase predates the Torricelli experiment, in which he used a glass vial and mercury to produce a vacuum, and the eventual discovery that the vast majority of nature is a vacuum (outside of the atmosphere of planets and stars).
- freehunter 6y agoAnd if it wasn‘t for gravity, everything inside the atmosphere of planets and stars would be rushing to fill that vacuum. Nature abhors a vacuum, but that‘s only tempered by the fact that there are more powerful forces than vacuums.
- skosch 6y agoThat's not quite right. Even if there were no gravity or other forces, there would be no incentive for matter to go in one direction vs another, regardless of the distribution of matter around it. Over time you'd get a uniform-ish distribution, but that's a question of statistical mechanics, not one of pressure differences. On earth, matter only rushes to fill vacuums because the surrounding air or water pressure pushes it in.
- jakear 6y agoVacuum doesn’t necessarily mean pressure-vacuum. It roughly means extreme concentration gradient, which is as you’ve described universal.
- xf00 6y ago> but that's a question of statistical mechanics, not one of pressure differences. My limited understanding was that 'pressure' is just a simplified way of speaking about statistical mechanics.
- smaddox 6y agoDon't forget, even within individual atoms, the overwhelming majority of the space is a vacuum.
- vkou 6y agoIf all of the matter in the universe were evenly distributed, it would be so close to a vaccum as to make no difference.
- taneq 6y agoIt also predates attempts to use dewatering pumps in mines, leading to the snarky variant “nature abhors a vacuum, but only up to 32 feet.”
- YawningAngel 6y agoWe have "nature abhors a vacuum" in English
- s_dev 6y agoI think these quotes are coming from either end of the spectrum of physics and biology and don't necessarily say the same thing.
- jakear 6y agoThe beauty of the phrase is that it’s universal.
- __MatrixMan__ 6y agoIs it? I want to talk with aliens as much as the next guy, but so far it seems like the vast majority of the universe is a vacuum--biologically speaking.
- TeMPOraL 6y agoThat's because there is not much stuff in the universe, and whatever there is, tends to cluster together under gravity. But within such a cluster, if you create empty space, something will want to rush to fill it in.
- pegasus 6y agoPhysically too. But it's a question of perspective: glass half-empty or half-full. Are planetary systems plentiful? It seems so, as a ratio of all star systems - as far as we know at least. Definitely not, as a ratio of the total volume of space. Similarly, the idea that we are mostly vacuum, because the elementary particles are so small compared to the size of molecules, etc. But that doesn't much change our intuitions about solidity vs. emptiness in every day life.
- jakear 6y agoThe way I see it, space is a life-vacuum, and human nature is to abhor that, as evidenced by the long-standing goal we have of interplanetary/intergalactic settlements. Which is to say: you’re thinking on the wrong timescale. Just wait and see. :)
- LinuxBender 6y agoThe best resources for this would be the sites that talk about the marine life around nuclear power plants. I do not have links handy, but those would be good places to start.
