        Perhaps we also have a barrier that prevents us from seeing more of our universe like the ice that could be preventing life under the ice on the rogue planets from seeing more.

              But don't stable ecosystems need producers e.g. plants to absorb light for oxygen release??
              Biological organisms need oxygen in (aerobic) respiration to release energy for metabolic processes.

                                i dont know if this is possible, but if it takes billions of years for the core to freeze, wont life have enough time to slowly adapt to colder and colder until it can live without a core?
