    If humans want to expand into space, it will take us incredible amounts of energy. How do we do that? Easy: we will just use the sun’s energy by realizing the most ambitious construction project in history. This is how it works.

      why bother with cloth when you could PRINT MONEY? Simply make a mobile game and ask money for it in return. That trick always seems to work and is completely legal.

                  Dyson Sphere, or breaking down mercury seems so complicated, nstead, to start.. Could we just transform the surface of mercury into solar panels all along the sun facing side, and a death star energy ray on the other end to beam or zap back whatever we need?

                      Since my childhood, I have dreamed of exploring space and stars, but today, when I grew up, I knew how much I and humanity were far from this dream, but this did not affect, its still my dream.

                                      So. How about this?

                                      No sign of alien life + huge amount of "dark matter" remaining a mystery + billions of years to develop and build ➡️ perhaps some could be "hiding" by collecting the entire output of various celestial phenomena and using cover as a means of defense. Easiest way to cloak a star and maximize energy output.

                                                                                  @Vali Malheur I agreed to that but let's just play a game of hypothetical. If somehow we reach this advancement in engineering and in interstellar space travel how would programming chips not melt due to the radio active heat coming from the sun at such a close distance

                                                                                • Vali Malheur

                                                                                  William Woods assuming by then, we would be able to handle that.

                                                                                  My thoughts though are, how would the people who oversee the operation handle the heat (and low gravity) on a planet closest to the sun?
