I have a good idea for building stars. We design and build something I call, A Reverse Dyson Sphere. First we design a star generating device similar to the one in China, but on a bigger scale, built out of denser metalic elements in order to contain the heat of 500 times the heat of the Sun in order to sustain a reaction. Then we design thermal heat steam powered turbines which generate more power in order to continue to use electricity to generate heat, and to create stars by heating an area of the Universe to create a super heated plasma effect, which would remove dark energy, dark matter, and anti matter from the region, which would create a star. But we have to make sure we do not design these stars in Dark Matter rich areas, because considering the oldest star being near us is 23 billion years old, then we should consider building in areas which might not have Dark Matter rich regions, incase we disturb something in the Universe.
