  • Technically the visible universe extends only about 13 billion light years from us. We can just calculate where that stuff is now because of expansion. And as I wrote the area we’re aiming for will surely change drastically the further away it is.

    These journeys wouldn’t take billions of years for someone traveling near light speed because for them the lengths would shrink down so much that they’d be negligible. Of course once they had slowed down those billions of years will have gone by for everything outside the space ship. So it’s not good for missions where you want to return home to your family afterwards.


  • The big problem is energy. If we had almost infinite energy we could accelerate to a significant fraction of the speed of light at a leasurely 9.81 m/s² in about a year. The travel at almost lightspeed would feel instantaneous for us. Add another year to decelerate at the same rate. We could reach any point in the visible universe in 2 years.

    Our destination would just be drastically different from what we observed, depending on how far away it was.

    Oh, and apart from the tiny energy problem cosmic radiation will probably destroy our spaceship. I bet at relativistic speeds you’d even get enough neutrino collisions to make them a problem.





  • You can access all Nextcloud files over WebDAV. That is natively supported by many file browsers, including explorer.exe on Windows.

    And you can choose in the Linux client what folders to sync.

    What the Linux client (in contrast to the Windows client) does not support is having virtual files in a folder and only downloading files on demand.

    Apart from that, have you looked at Opencloud?







  • I think this way of speaking developed in the USA over the last 30 years or so.

    I saw a video about that a few months ago how people seem to put the sh sound into more and more places. Like they don’t say stormtrooper, they say shtormshrooper. Can’t find it anymore and don’t remember the channel.

    To me it sounds weird. We learned this as a distinct difference to German that it’s straw and not shtraw, like it would be pronounced in German.
