    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.

      I agree. But don't forget if we can captured all the energy of our sun we can make a home base in another unhabitable planet, teraforming one of them and travel to outer solar system..so it means live in a planet with slightly darker after covered the sun, is a peace of an cake for humanity.

            3 minutes in and I can tell ya right now a Dyson Sphere isn't possible or ethical because you'd literally be destroying a planet to have the materials needed. So in the long run, it wouldn't be a worthy investment.

            Oh and one more thing, if a planet was to lose mass cuz of the deconstruction, it's orbit will be disturbed and throw it out of it's original orbit.

                                  If we disassemble Mercury would that not create a chain reaction of changed orbital trajectory for all planets? Hence destroying us all?

                                      You can't rail gun a satellite into orbit, it would come back and hit the planet, you need another velocity change at the to of the hyperbolic arc to get a stable orbit.

                                          wouldn't a dyson sphere pose gigantic problems by blocking sunlight ?

                                            Renewable energy is heavily green washed and is a step backward from nuclear energy, whose greatest danger lies in the lack of innovation and funding it deserves because of its stigma.

                                              have a question does the dyson sphere will block the light to us and make us die of cold ?

                                                if somehow we managed to collect the unlimited energy, so do you think we can find a solution for immortality?

                                                  The problem is we can suck all the energy out of the sun and possibly run out.
