  • Yeah I figured it maybe also had something to do with the distribution of matter throughout the universe. We assumed when we made predictions of the distant past that the supermassive black holes at the center of galaxies were the same mass as they are today, but if they were less massive then it might help explain why black holes didn’t gather as much material into it’s orbit as we would have thought.

    I think you’re right though that it has more to do with the negative pressure that space and the black holes seem to exert although I must admit I don’t really understand what that means or how you would get a negative pressure from a black hole or from space.

    “dark” in scientific terms just means unexplained. We’re very, very, very, and I cannot stress this enough… VERY sure that dark matter and dark energy exist, but they will remain “dark” until we discover what they are/what’s causing the effects that we see. Aether was just unfounded non-sense that was based on practically nothing.

    Cool animation! 10/10 style points!

    For those unaware, Adobe changed their terms of service recently to say that if you agree to the terms then they officially own anything you create using their software and can use it however they want. Specifically this line:

    you grant us a non-exclusive, worldwide, royalty-free sublicensable, license, to use, reproduce, publicly display, distribute, modify, create derivative works based on, publicly perform, and translate the Content.

    This probably means that Adobe has built some kind of backdoor into their programs to access your files and send it off to their servers. Pretty shitty of them!


  • For example, carbon dating took discoveries including counting tree rings to determine a tree’s age, the origins of all the radiation on Earth – spoiler: it was the Earth itself, but also cosmic rays which was the important bit, nuclear half-lives and creating a chart of specifically useful half-lives for historical dating, the discovery of a rare isotope of carbon which can only be made by cosmic rays (carbon-14) as a near perfect clock for human timescales, how to build a sensor that can read faint carbon-14 radioactivity while filtering out all the radioactive noise from the environment, making another chart of expected radioactive readings based on geographical location including the depths of the ocean, and of course not to mention all of the archeological data used to calibrate all of the charts and devices used in the process.




  • Being excited about being wrong because either way it’s information

    This literally is the basis of science that I think a lot of people misunderstand. Science doesn’t prove anything conclusively. What scientists try to do is disprove the leading theory and when they can’t, it adds to the pile of evidence that increases the likelyhood of the leading theory being correct. Even things that we’re very, very, very sure are correct are still like 99.99999999999…% confirmed.

    A good example that’s often used to show how it’s more important to try to disprove a theory rather than trying to prove it is the existence of black swans. It was long thought that all swans were white and every time someone saw a white swan, that idea was reinforced. But when someone actually went out of their way to go looking for a black swan, they found a bunch of them!





  • I ran Ubuntu for a couple of years, and then I switched to PopOS because I didn’t like the direction that Ubuntu was going.

    imo Pop takes everything that made Ubuntu great and makes it better. It’s not bleeding edge though, but it is stable if that’s what you’re looking for.

    I recently made the switch over to an Arch based distro for the first time ever (Garuda Linux is the distro) and I’ve absolutely loved that change too. I feel like Garuda at least, I can’t speak for all Arch based distros, but Garuda is very user friendly, sleek with KDE apps including Plasma, and very powerful. I like to game on my laptop and have definitely noticed some framerate increases after switching to Garuda.
