  • The bottom-most bridge was built around the 12th century. How the hell they managed to build stuff like this way back then staggers me.

    I find it hard to relate with this sentence. That’s just 3 bridges on the top of what seems like a natural rock formation, right? With 2 being arches and the top one being a modern-ish structure.

    No matter how deep it is, it’s narrow enough to just move a prebuild wooden foot bridge used for people to go around constructing the thing.













  • This is a nice example that also makes me think more questions.

    • Will the hole punching be forward or backward?
    • Assuming infinite deceleration, for an observer on the other end of the barn, will the barn be punched through, before or after the pole-pusher has stopped?
    • For the pole-pusher, will the barn be punched through, before or after it has stopped?

    Gets more interesting

    The only time any information can be encoded onto entangled particles is when they’re created.

    If that were the case, then we aren’t really doing FTL communication, unless we manage to entangle them at a distance. No?

    OIC, it’s still useful if we want to make a secret key and send it somewhere. Then both sides can take a reading sometime in the future and they can then use whatever cluster of entangled particles they saw, as the symmetric key.
