| − | :Seconded/thirded. Capillary action isn't even what they were expecting. The small amount of water in the lower recepticle indicates they correctly ''filled'' the tube, but then as the longer length drained it did not then induce further flow up and over through the shorter length. e.g. nature no longer abhored the resulting vacuum (or there was increased negative-pressure vapourisation, beyond that previously expected, or other method of seepage 'airlock'-breaking) and thus the short-end also drained straight back out again instead of becoming a potentially self-sustaining inflow to the whole siphoning setup. | + | :Seconded/thirded.

| − | :::Indeed, even having an especially large diameter "tube" (/pipe etc) can allow air from the bottom to flow up to the peak & break the siphon effect. For reliable results, the lower end needs to be kept immersed or the hose needs to be relatively small in diameter.

| | :While the capilliary action element ''could'' induce the start of a rather limited 'empty' siphon setup to start (maybe, I'd have doubts about the 'fluid friction' actually acting against the gravity-feed part, once the surface-tension bit has "climbed the mountain" and started to merely seep out of the other end, almost incidentally, for a sufficiently thin tubing where CA is a significant factor), this suddenly failing for whatever reason (surface-tension effects being nullified) wouldn't then send a token amount of water into the low bucket, nor particularly stop unrelated siphon-flow from continuing properly (in fact, suddenly 'interaction-free' liquid and tubing might siphon ''faster'', with effectively zero fluid boundary effects dragging on the induced flow). | | :While the capilliary action element ''could'' induce the start of a rather limited 'empty' siphon setup to start (maybe, I'd have doubts about the 'fluid friction' actually acting against the gravity-feed part, once the surface-tension bit has "climbed the mountain" and started to merely seep out of the other end, almost incidentally, for a sufficiently thin tubing where CA is a significant factor), this suddenly failing for whatever reason (surface-tension effects being nullified) wouldn't then send a token amount of water into the low bucket, nor particularly stop unrelated siphon-flow from continuing properly (in fact, suddenly 'interaction-free' liquid and tubing might siphon ''faster'', with effectively zero fluid boundary effects dragging on the induced flow). |

| | Of course, if some physical law would actually stop working, people wouldn't be confused. They would drop dead. Due to physical laws working on level of elementary particles, every change would have lot of different effects ... and living organism live only thanks to being very carefully balanced in lot of regards. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 20:49, 12 May 2023 (UTC) | | Of course, if some physical law would actually stop working, people wouldn't be confused.

| − | :(I get that reference... :) However, launching off that to say: ) There's an old (short?) story... H.G. Wells era, possibly, but not him I think... where someone (who happened to be the first decent but amateur astronomer to get a cloudless patch of sky, one night) realises the Moon is in the wrong place, and the news then reaches (and troubles) the professional community who get a chance to observe/notice the change for the first fime and confirm it.. A 'glitch' seems to have passed through space and moved/retimed it, for a limited time, before it later snaps back to where (in the orbit) it now should be.
| |
| − | :The trace of the glitch are seen further afield (implying a 'beam' of 'wrongness'), and ultimately it spawns something like Experimental Theology whereby observations of such clear "hand of the Creator" changes (implying we're essentially in a simulated universe being operated by a 'universal programmer', but in pre-computer terms) merge or muddy the boundaries between scientific rationalism (which clearly falls short) and religious philosophy (where undeniable 'proof' of something godlike is now suddenly an ironically confounding factor).
| |
| − | :Cannot remember much about where I read it, I may be presuming some details about it that aren't actually there (even removing obvious mix-ups with similar brands of tale) and my Google-Fu fails to establish any obvious online reference to it (even just title+synoposis), so instead I'm setting down the 'spoilers' without reservation.

| − | I think if I added it to the article body it would get reverted, but the content seems very similar to how AI media produced delusional worlds for so many factions of people. It is not at all a big stretch to imagine people stepping into a metaverse or matrix where they aren’t sure what is real and physical laws match their intuition more than is actually correct.

| − | ::There is Slate that turn into lava spontaneously after lying around for thousands of years. I think the area they are in is called "Smoking Hills". There was recent research why that slate does this while in much the rest of the world slate is just flat, black rocks. I still believe this title text is about plutonium, though, as that slate produces so much heat, that one still hasn't managed to measure how hot it gets - but it produces that heat not for an near-infinite duration.--[[User:Gunterkoenigsmann|Gunterkoenigsmann]] ([[User talk:Gunterkoenigsmann|talk]]) 01:48, 14 May 2023 (UTC)
| |
| − | :::The only {{w|Smoking Hills}} that came to mind was natural shale-fires (chemical burning, and not hot enough for remelting to magma/lava.
| |
| − | :::Possibly there is a {{w|natural nuclear fission reactor|situation}} where it has done as you say (in some natural mass of rock, spotted somewhere in this planet's lithosphere, or elsewhere out there), but given the fine line between nicely sustaining and runaway chain-reactions, I'm not sure how easy it is for nature to 'engineer' a way to land on the {{w|Corium (nuclear reactor)|middle ground}} and not go supercritical.
| |
| − | :::In order for accumulating ores to not just start a low-level fizzle (as above), over millenia, you might need separate ore-patches either side of a fault to come together in a suddenish techtonic slip, rather than a slow buckling of layers to increase effective ore-densities. And then you've got earthquakes, already, so not sure if the very low-grade nuclear explosion that is awfully close to being possible in this chance contrived example (at one end of the probability curve, unless U<sup>238</sup> content is somehow preferentially leached out?) is going to be noticable.
| |
| − | :::But ''just'' hot enough for lava? If not already close to melting, anyway, under local temperatures and pressures? Not sure we've seen anything like it, even if it is technically feasible given enough happenstance setups by geology(/exo-geology), since planets formed.

| − | ::::Any sufficiently large rock containing sufficiently high concentrations of radioactive materials (such as the Earth) will partially melt. The energy is released slowly by decay not through fission. The large size ensures that the center is well enough insulate that slow heating accumulates until it reaches lava temperatures. The finite size ensures that enough heat leaks out that the magma does not become gas.[[Special:Contributions/162.158.158.170|162.158.158.170]] 18:29, 16 May 2023 (UTC)
