    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 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.

                                            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.

                                                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.
