With normal physics, in a closed-curve hyperspherical universe with a static 4d radius of a few light years, you're looking at Olbers' Paradox within a few thousand years. Every line of sight leads to the surface of one of the stars eventually, and therefore the entire sky radiates as much energy as a stellar surface. Everything gets baked, melted, and turned into a plasma in fairly short order.With Grandfather's tech, handwave handwave, you can just divert the excess starlight somewhere. Maybe it's fed back into our universe, smeared out over a few cubic lightyears so that it's almost undetectable. Maybe he captures all the excess photons and converts their energy into strange matter and hot fudge sundaes. Handwave, handwave, handwave.On Thu, Apr 4, 2019 at 1:22 PM Phil Pugliese (via tml list) <xxxxxx@simplelists.com> wrote:After recent discussion about FTL travel, I started thinking about G'father's 'pocket universe/s'. (I think if there's one there could easily be more, who knows?)Anyway, the one we know of for sure in the TU has been in existence 100's of thousands of years, right?So the stars/suns contained in it have pumped out an unbelievably enormous amount of energy into a basically 'closed system'. (no 'expanding universe' here, AFAIK)So what happened to all that energy?Both 'conventional' & TU 'handwavium' speculation welcomed!TIA,-----
