To be pedantic, the crystal is the rectifier in a crystal radio. Tuning was (or is, since there are still people out there playing with these things) still usually done via a normal tuned LC circuit. But yeah, we've gotten a lot better at rectifying too.
But we do use crystals for generating a stable frequency reference, which is then used in tuning.

Another theory I have is that truly sufficiently advanced societies stop giving a shit. They figured out how to be in equilibrium with their resources and are capable of being happy that way. Giving shits about things is one of the big reasons we have wars and other potentially civilization-ending possibilities. Even if we are able to put 100 humans on a spacecraft for 100 years hurtling across the galaxy I'm pretty…
Well if a planet has a few intelligent species, the expansionist one would dominate the rest. If there is no expansionist species, after a time one will emerge due to mutation over time. Look at humans - there were a bunch of other intelligent species around the time humans came to the scene - we out expanded and outcompeted all them. Now of course this is just a sample of 1. But also seems kind of inevitable. So if…
Are there any good resources for someone to learn how to write some Numerical Relativity code?

The hull is in a vacuum, and so are the eardrums.
What part of the question or the premis stipulated that the eardrums are in vacuum? Who cares if the eardrums of a dead human vibrate? The hull and all other parts of the ship or suit around the eardrums would all also vibrate.
GP specifically said "hear things explode in space".

For such a species, there would likely be no selection pressure towards such a trait. I suspect it's actually the opposite: being less expansionist could have enough benefits that it would become widespread entirely through random mutations.
Infinite growth isn't possible, desirable, or even "natural".

The idea is that the eardrums are not vibrating due to the air - so such medium is irrelevant to the question. GP specifically said "hear things explode in space ".

One of the reasons I no longer ask questions on Physics stack exchange: 1. I asked "how powerful" such waves would have to be to be audible. 2. I directly linked to another question whose accepted answer said "these waves can wiggle your ear drum" 3. Got my question closed as a duplicate but the link was to different question that only asked "is it possible" (and accepted the answer "yes") without there being any ans…
Why would you ever consider asking an LLM a question like this though? They just make plausible-sounding things up, even if sometimes they're correct.

This is indistinguishable from my experience described above.

But surely it isn't wiggling the tissues by sound waves passing through matter, but by vibrating space time itself? The skull shouldn't be able to resist gravity waves any more than soft tissues or 10km of lead?
When a gwave passes through, since the space contracts or expands, you get changes in density, since bone and soft tissue are different densities, there should still be a pressure differential that can be heard.
