As we have explained before, scientists understand that a vast percentage of the matter in the creation is something they call dark matter. The simplest way to understand dark matter is to realize that when something is spinning around a core, there must be a force to keep the spinning mass from flying away because of centrifugal force. The dark matter mystery is the unknown quantity preventing spiral galaxies like the Milky Way from flying apart.
If you spin a child around so fast that their feet come off the ground, you must hold their hands tightly. If you let go, they would fly off away from you. Stars going around the center of a galaxy also have to be held by some force. The stars move so quickly that no known force could keep them where they are. That means there is a gravitational force we can’t see holding the stars in their position. We refer to the mass that exerts that gravitational force as dark matter.
Astrophysicist Peter van Dokkum of Yale University has announced the discovery of a galaxy known as DF2, which has stars and star clusters moving at a very slow pace around the core of the galaxy. In all other galaxies having stars at the same distance as stars in DF2, the stars are moving three times as fast as the stars in DF2. That can only mean that there is less dark matter in DF2.
This discovery increases the dark matter mystery because it appears that dark matter is not constant in the cosmos. The amount of dark matter in a galaxy depends on what is needed to keep everything moving at a speed that produces stability in the galactic system. There is a great deal of debate about this discovery, but it appears that the design of galaxies has a new variable that is critical to their existence. That critical factor is how much dark matter has been supplied to keep the system stable. God has tools affecting the creation that we are just beginning to understand. The role of dark matter is only one of those.
