I would add "at any given point". Our technological civilization grew in just about 3k years (give or take, add a zero, divide by ten, it won't change the weight of the argument by much), there is no way to say how long it will survive but I am rather pessimistic and I don't think it will last...

Interesting approach, and definitely good candidate for something that can be turned into a detection technique. I feel like it is kind of a measure of "how thermodynamically impossible is to see the molecule produced by a natural, abiotic process" (yes, very handwavy, but I am sure it is the...

(emphasis mine) Yes, we haven't seen anything that can't be explained as a natural process (there are some strange observations, but they are random and inconclusive) - but how much have we seen? Can be that the advanced life is quite common, as opposed to intelligence capable of producing...

To some extent: your guesses are as good as ours. First of all: as I already signaled there is no way to add enough protons through irradiation to make observable difference in pH. Other than that - what happens is not much different from what happens during nuclear fusion, where instead of a...

Something like that. Try to estimate forces involved between - say - millimole of protons and millimole of electrons separated by 1 meter. Or just watch any video about Kelvin water dropper, while it is not about irradiating solution the general principle - of water becoming charged - is very...

No, I mean "any glass that is SiO2 based" - which in practice means all of them. Sure, there are differences, but as long as we are talking about laboratory glass (as opposed to "any glass container sold for general public") they shouldn't matter. Disclaimer: all possible warnings about...

And there is no way to help without any information about the enclosure itself.

Acids do have a common characteristic - they produce H+ when dissociating, and H+ is an oxidizing agent (mildly strong), but their other properties vary, which often makes one better for a specific task than others. Silicate glass is in general good for all acids with an exception of...

And how do you judge, if the answer is beyond your knowledge?

They won't. The process has already started.

Several processes - one is that at some point "all questions were already answered", quite often it was enough to google for problem to find several discussions and explanations. Second is that demographics changed - people asking questions expected more and more to be treated nicely, so started...

Someone liked my post and it appeared in my feed. Interestingly, there is a paper now suggesting I was right and it is an artefact of the metrics used when training: https://www.arxiv.org/pdf/2509.04664

At some point search for better solutions becomes quackery.

Pretty easy to build using any programmable microcontroller. Start with an Arduino, as it is cheap and probably the easiest due to tons of tutorials.

Wow. Last number I heard about was around 200.
