    It’s only something we can speculate about. It represents a limit to our ability to gather any evidence that might validate those speculations. We can’t say what happened before it, because time itself was one of the things that popped out of the big bang. What would “before” even mean if time didn’t exist?

    Even if time and matter did exist in some sense, we can’t get any evidence for it. We can’t make any kind of useful theory about it. At best, we can make wild guesses.

    We could also just say “we don’t know what it was like”. Russell’s Teapot suggests we should instead say there was nothing, because we can’t prove there was anything.









  • We have a pretty good idea. Post-quantum crypto is a real thing. There are conferences in the field about it.

    Certain classes of problems are shown to be faster on quantum computers. One of them is factoring prime numbers, which is what our public key crypto is based on. Traditional block ciphers are also somewhat vulnerable, with their security is effectively cut in half. In other words, a 256 bit key is as secure as a 128 bit key. That solution is easy; we double the key size and call it a day. Public key crypto, however, is a bigger problem. Needed whole new algorithms.

    The big unknown is how powerful quantum computers will get. It’s going to take a lot of qubits to break public key crypto. It may be completely unfeasible to juggle that many qubits in superposition. It’s also possible it will only barely do it, in which case we can also increase the key size and call it a day. But post-quantum crypto is being worked on, just in case.

    Zoom is still bullshit. Their software has had all sorts of problems that don’t need QC to exploit.

    The scientific taxonomic system was made, in part, because traditional colloquial terms are a mess. For example, “daddy longlegs” refers to a type of spider in my area, but there are two other animals and three plants that it could refer to depending on where you grew up. Taxonomists saw that there are ten different standards, decided to make a new one to replace them all, and for once, it actually worked out for the most part.

    “Bug” is one of those old terms. It might have been mapped post hoc on top of the modern taxonomic system, but it didn’t start that way, and isn’t always used that way. I wouldn’t expect an entomologist to use the term at all in formal contexts.




  • They’re human. I don’t think it’s been fully covered how this happened, but there was one interesting piece that didn’t get published.

    It combines Lucas’ various other movies like THX-1138 and Indiana Jones. Earth is overrun with an AI-driven society in THX, and a group of humans get on a ship to escape. They fall through a wormhole and end up in the Star Wars universe, becoming the first humans there. Han and Chewie travel back through this wormhole, and crash land on Earth in a forest. Chewie survives, and him walking around starts a bunch of stories about Big Foot. Indiana Jones investigates, finds the remains of the Falcon and Han, and wonders why this guy looks familiar.

    I think American Gothic was in there somehow, too.

    Even if it did get published, I can’t imagine it being taken seriously as Legends canon. Chewie was already killed off in the Yuuzhan Vong stuff with Han surviving. But that’s the closest to an answer we ever got.

    As it stands, Courscant is often believed to be the original human homeworld in-universe, and whatever the truth is has been lost to time. Star Wars is interesting with how old the universe feels–which is more of a Tolkein-like property than traditional science fiction–and this is a pretty good example.
