      Did you see what that type X civilization did with the magnetic fields of the black hole at the center of the milky way?

      I always thought Dyson Spheres were art project BS for advanced civilizations. If you are that advanced you can get energy better ways.

      We are literally on the edge of greatness. All we need is a push. I suggest the government work with NASA to invent an alien invasion set for the next 100 years. All the best technology has been based on war

              Could we entangle subatomic particles in Earth orbit, then shoot those particles into the sun, while the entangled particle is inside some reactor in Earth orbit?

                                    He cant be farthur from the truth, humanity is supposed to already be in space but it seems like we are regressing back to the racism filled 1800s and waging war over stupid junk, and worrying about down to earth junk. And money......that stupid word "money". The reason we cant go anywhere its because of "money" money does not make the world go round and its not a necessity to live you take it out of the picture who knows what people could accomplish. But still we idolize that green piece of paper. Well when we end up destroying ourselves when we run out of energy lets see how well your stacks of GREEN PAPER keep you alive then.

                                                                                What if this channel is an alien organization with higher intelligence and its trying to give us these tutorials and explain stuff to us so that we can use the knowledge and build stuff so that we can finally expand
                                                                                But that’s just a theory
                                                                                A film theory!!!
