    But then there’s the guy who added all the mass and energy of the observable universe, calculated its’ Schwarzschild Radius, and came up with 13.8 billion light years.

    There’s also how our observable universe’s Hubble Horizon acts like a black hole event horizon, the way in which even the speed of light is insufficient to escape beyond.

    A lot of the math inside a black hole is eerily similar to the math of our own horizon, as traced by the age of the universe plus the speed of light.



  • I watch a lot of science channels and videos on YouTube, there’s just so much extraordinary content out there, going deep into the math and formulas of cosmology and physics.

    Sooner rather than later, the algorithm started pushing this woman’s videos on my homescreen. She most definitely leans towards the clickbait titles and bombastic controversy, two things that I hate, so it was again time to take out the digital machete and hack away at the algorithm, as I do nearly every day. But then she just keeps on popping up in other people’s videos and podcasts, some trustworthy content creators seem to have a high regard for her academic work.

    But just like assholes like James Woods or Joe Rogan have made themselves unbearable for me, even retroactively, just their presence and voice take me out of whatever I’m watching, put me in a bad mood, so too it is with Hossenfelder. In an age of the digital smorgasbord, a never-ending stream of science and math educational content of a high level and mind-blowing quality, I can survive and thrive just fine while avoiding the assholes.




  • Take it one level lower on down, when you’re the size of an electron, orbitals are wild, turbulent places, sometimes sharing electrons which also often get zapped by light, so they jump to a higher orbital, then they randomly spit out that photon and reappear back down… all the orbitals of a molecule violently jiggling all the time.

    Take photosynthesis. Simply put and to oversimplify but it’s essentially accurate, a photon hits an electron bullseye in a leaf molecule, which sets off a wave of energy in motion, breaking up molecules, reassembling them into sugars and waste product (oxygen).
    A red photon raises an electron one orbital up, that sets off one process at a certain level of energy. A blue photon raises an electron two orbitals up, that sets off another process at twice the energy level.







  • Many horrible things that were preventable, happened.
    But you know why what happened?

    It was the very same mediocre electoral stupidity we see today, the precious, lazy assholes, easily-manipulable into inaction, who latched onto the murdoch/limbaugh/drudge report propaganda of the time.

  • This was originally a Warhol idea, wasn’t it?
    A six hour film of the Empire State building, as the day goes and the lighting changes, I think it was meant as like a window from an apartment or office right in the thick of Manhattan.

    Truth be told, I don’t hate the idea. Currently, it could be a framed digital screen on a loop, or showing a webcam feed. Why not a live view of Istanbul, or of the Moroccan desert?
