  • It’s exactly the same gravitational pull as the star that previously collapsed… (And I’ve not read the article (yet), this is just a personal nitpick that I’ve had for a LONG time).

    –edit after reading the article–

    In terms of inevitably falling into a black hole, it’s only the material that formed interior to three times the event horizon radius — interior to what’s known as the innermost stable circular orbit (ISCO) in general relativity — that would inexorably get sucked into it. Compared to what actually falls into the event horizon in our physical reality, the purported “sucking” effects are nowhere to be found. In the end, we have only the force of gravity, and the curved spacetime that would result from the presence of these masses, affecting the evolution of objects located in space at all. The idea that black holes suck anything in is arguably the biggest myth about black holes of all. They grow due to gravitation, and nothing more. In this Universe, that’s more than enough to account for all the phenomena we observe.

    That summary explains it better than I can.




  • There’s a lot of misinformation in this thread. Sure, they broke 22-bit RSA encryption. But here’s the thing - that’s proof that a suitably large quantum computer can break any size RSA encryption in the same amount of time it took to break 22-bit RSA encryption.

    Because of the way the annealing process works, it’s a known-time process, no matter how many inputs or q-bits are used. We don’t have the ability to create a computer with sufficient q-bits to break anything more than 22-bit at the moment, but current estimates are that in 10 - 15 years we will have enough to break 1024-bit.

    And it’ll take the same amount of time as this 22-bit process took.

    And that basically means we need new encryption processes within 10-15 years, that are quantum safe, or all our encryption is belong to whoever has these quantum computers.


  • In one sentence, you say, “just use a password manager”, on the next, “not really an improvement if you need extra software”. I’m not sure what argument you’re having, but neither one really addresses what this article is about.

    This keeps the passkeys in the password manager (I use dashlane, it rocks, and synchronises the passkeys just like the passwords), but this new protocol allows you to change and export the passkeys to other password managers, preventing vendor lock in and allowing for transfer to another password manager.

    Hope this clarifies things! And everyone should use a password manager of some kind; we should expect whatever site we’re using to be hacked, and the only way to be safe is to have a unique password per site.
