Under the given assumptions (a) Assume that all of the atoms in the universe are hydrogen atoms in stars. The normal matter can cool and become a dense galaxy, but the dark matter has a harder time clumping together, and is therefore located in a much larger 'halo' around the visible part of the galaxy. Pages 182. Raymond. The IAU goes on to say that a planet is anything that’s big enough so that its gravity molds itself into a ball. So if you have ever read that our brain connections outnumber the stars in the universe (perhaps here or from this book), I hope you frowned in skepticism. Computer models that scientists have made to understand galaxy formation indicate that galaxies are created when dark matter merges and clumps together.
