For some reason they don't mention in the description that most or all of these games are not videogames, they are tabletop role playing game manuals. (The digital downloads are .pdf files)
Nothing wrong with that of course, but it certainly seems like an important detail.
Yes, the speed of sound in an object is how fast neighboring atoms can react to each other, and not only is that information (therefore limited to C already) but specifically it's the electric field caused by the electrons that keep atoms certain distances from each other and push each other around. And changes in the electric/magnetic fields are famously carried by photons (light) specifically - so even in bulk those changes move at the speed of light at most
I didn't see anything about port knocking there, it rather looks like it has the opposite focus - a quote from that page is "features that support widespread scanning of many machines are supported, while in-depth scanning of single machines aren't."
Expanding a little on the last part, Earth's orbital velocity is about 29.8 km/s so that's the speed at which we would suddenly be leaving the former location of the solar system in a direction that depends on what time of year it happened. Regardless of direction though, the escape velocity of the Milky Way around where we are is about 544 km/s so there's no way we'd be leaving the galaxy. On the other hand the plane of the galaxy is only about 6 degrees off from the galactic center at the moment, so if this happened at the right time of year (don't know when that is) we could launch somewhat towards the core. We would not however get very close to it because the sun's own orbital velocity is about 230 km/s so we'd still be in close to the same galactic orbit overall, just potentially a bit more eccentric.
There used to be pornlemmy but it died (and was too restrictive in my opinion)
I don't know why not the one you named, as far as I know it's the only remaining general porn instance. There's just a few scattered communities on other general instances, and there are specialty instances like your own.
There's also a bit on Mastodon but mostly reposting from reddit.
Friction (as in the atmosphere) would matter a lot in this case. Bread is low density and would have a rather low terminal velocity. Basically doesn't matter how high you drop it from.
(until high enough that you are letting the burn part happen on the way down, but then it's difficult to capture that energy)
