  • 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.






  • She lived in the non-Jewish parts outside of the proper city and worked in an ex-Sowjet party building. When she arrived it still had Trotzki, Lenin and Stalin statues. And even then she couldn’t move freely and had to give the correct passwords when moving from one part of the city to another.

    And still life went on in Minsk. Most people there just had to keep on living. Farmers still regularly brought wares. Even theatres and cinemas were still working even when good food was scarce and expensive.

    She did mention seeing fires at night in the distance. That was officially attributed to the rebels. That was easy to believe for her since some of her colleagues died from hidden bombs.

    The closest she came to the actual crimes was when she got a new bed from the storage where all the furniture from the murdered people were stored. Though back then those were from “defeated Russians”.

    With the way she didn’t shy away from describing atrocities she did see (before the Nazis, from family members and of course during the war) I believe that she did not know what was happening in the ghetto. The way she wrote she didn’t even know when she wrote it that these people were killed right in the city. She (and me before you showed me) thought there was a camp near the city. But not a whole part of the city itself.

    I’d honestly like to see an editorialised edition of her memoirs published that showed what really happened around her. To put it all into perspective.








  • 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?
