More than 5,700 Palestinians have been killed by Israeli airstrikes since the war began, according to the Hamas-run Ministry of Health in Gaza, the New York Times reported.
I would take this number always with a grain of salt.
Understandable, it's a claim made by a partisan faction after all. That said, according to this random X/Twitter account the IDF itself claimed two days ago to have made "over 10,000 targeted strikes" on Gaza since the beginning of the current conflict, so the casualty number given by Hamas works out to about 0.57 fatalities per strike, which doesn't seem like that outlandish a claim to me given how densely populated Gaza is.
Long to infinite timescales for it to crystallise, that is to solidify. This is explicitly noted in the abstract of the paper the article is based on. I understood the "short timescales" on which it "relaxes towards the liquid state" to mean more than one human life time based on figure 4 (the image also shown in the article), but not so sure about the 10ky cited in the OP though.
Yeah that might indeed be an urban legend, could be manufacturing artefacts as claimed here. However I will note that the version of it I am familiar with isn't about "bull’s eye marks, warps, and lines" as that article states, but specifically about old windows being thicker only at the bottom.
