As per NASA, Here's the Best Way for Humans to Conquer the Galaxy

A team of Chinese researchers won a NASA contest to design the best possible method for humans to colonize the galaxy. His plan for the construction of an interstellar human civilization can be seen in the animation above.
The competition consisted in solving a complicated problem of geometry and creation of routes with limited resources. NASA asked participants to imagine that, in 10,000 years, humans have all decided together to go to the stars. But there is a trap:
"Although technologies and knowledge have progressed dramatically," NASA wrote of this imagined future, "we are still subject to the tyranny of inertia and stay away from the almost instantaneous space travel represented in a fantastic way in science fiction. However, huge steps have been taken in the ability to live in space, so that the ships of the self-sufficient settlers can travel through space for hundreds of thousands of generations, making it possible for humans to reach and establish other star systems. " . [The 9 most intriguing planets on Earth]
Competitors were asked to plan a human expansion in these circumstances from our home solar system on the edge of the Milky Way galaxy. A colony ship (whose route is represented by a line on a map) could be directed from any solar system to another. Once that ship arrived, more ships could leave that new solar system, unfolding in multiple directions. NASA judged the proposals based on the number of systems they reached, the extent of the area they covered and the little energy they spent to spin their boats.
The winners were a team called NUDT-XSCC, whose members were from the Faculty of Aerospace Science and Engineering of the National University of Defense Technology and the State Laboratory of Astronautics Dynamics of China. They became the tenth winners of the NASA Global Pathway Optimization Contest and will present an article on their results in August at the Astrodynamics Specialists Conference in Maine.
