Really enjoyed reading this. I wonder where the finer barrier is for star making like 12.998mj etc . I like thinking about whether a planet could become a star one day, gives me an idea for another story :) And still whenever i see deuterium crop up i remember that 1 in 6000 particles of water in a bottle will be a heavy hydrogen. mmm. haha... it blows my mind too much to try and imagine walking through fat gas :D
