The gist of this particle is how the galaxy gains power maintaining its normal function.
At the beginning, the author points out his or her main point and mentions a recent fruitful and valuable research finished recently. In that study, researchers have taken lots of time to use stimulation of several galaxies, including milky way which we live in, to figure out the process of energy formation in galaxy, because in real world, this kind of process may take so many billions of years that a single scientist can't find out the result only be observation during his or her whole life.
Then, the author mentions conventional and common-shared theory on this point to make a contrast to the latest finding, which is totally opposite to the early one and finds the galaxy formed and maintained by the "cold material" which is unlike to the "hot one" in the early theory.
Moreover, the author specifically and definitely describes the stimulation part in the recent research. In this part, according one researcher, it's hard and time-consuming to stimulate the precise movement of inter-and-intra each particles, because there are a huge number of particles in a real galaxy and so are the stimulated one.
Finally, the author mentions the theoretical and practical value concerning the recent research.
