  • This is all correct and is commonly known as redshift or blueshift. It’s the same idea as when a car or train passes by and you hear the pitch get higher as it approaches you, and then lower as it leaves you.

    To add to it though, stars themselves (regardless of our perspectives on them) do come in different colors. Betelgeuse is an easy star to find in the night sky that has a distinctly redder color compared to most stars. It’s the left armpit star in the constellation Orion.

    Stars have different colors based on many factors like their composition and how hot they burn.









  • Yes please! Lemmy.world and lemmy.ml shouldn’t make up the majority of my feed.

    I think best case scenario, you have themed instances based around art, tech, politics, news, gaming, food, etc, and the largest communities are hosted there. Then you have “catch all” instances like lemm.ee which federate with everything, there can be as many of these instances as needed as the user base grows. These types of instances should be where the bulk of the new user accounts go, assuming just an average user looking for a /all replacement. Curated instances like beehaw allow for a more fine-tuned experience, but should still function basically as a catch all and not as “hosting the content” instance.

    However I understand that building up to that is damn near impossible with the current infrastructure. We would basically need a means to migrate an entire community to a new instance, while simultaneously updating everybody’s subscriptions to reflect the new home of the community.



  • None of this applies to the average user though.

    The vast majority of devices sold come with Windows or MacOS, so you’re suggesting that the average Joe should wipe their drive, pick a distro, and self-install and maintain a new operating system.

    You and I know that it’s not as difficult as it sounds, but that’s asking a lot from people who can’t even bother to reboot their system when there’s been an update pending for 10 days.
