    Space bending is a general relativity thing, which isn’t really related much to how mirrors work.

    Regarding the medium bit, photons being absorbed and remitted can’t explain how light moves slower in glass. This is just an extremely popular myth. Photons are only absorbed by atoms at very specific frequencies. Also, the entire reason glass is transparent to begin with is that it’s not absorbing the photons (requires too much energy to bump the electron’s energy level so the photon isn’t absorbed and it keeps on trucking). Also photon absorption and remission is stochastic so there’s no way to control the direction it happens in or how quickly it happens. Random directions of remitted light would make glass translucent, not transparent. So for a few reasons, that’s not how it works.






  • Jobs was an asshole to his colleagues and he made grave mistakes about how to treat his own cancer which led to his death.

    But with that being said, he helped make Apple, left Apple to make NeXTSTEP, then when Apple was in the dumps they re-hired him, at which point he turned the ship around and put Apple onto the path to becoming the hegemon it is today. Apple’s well-being appears to have had a clear response to Jobs’s presence. So while he may have been an asshole, but he was at least a functional asshole who got stuff done professionally.

    That’s pretty much the exact opposite of what Elon is doing with Twitter.
