Galactic motion refers to the movement of galaxies in the universe. Galaxies are large systems of stars, dust, and gas that are held together by gravity. They can rotate, orbit around other galaxies, and move through the universe.
Galactic motion is explained by the laws of gravity and motion, as described by Isaac Newton's laws of motion and his law of universal gravitation. These laws state that all objects in the universe are attracted to each other by a force of gravity, and that the motion of an object is determined by the forces acting upon it.
The main factors that influence galactic motion are the distribution of mass in the universe and the gravitational forces between galaxies. The larger and more massive a galaxy is, the stronger its gravitational pull will be on other nearby galaxies, causing them to move in certain ways.
Dark matter is a type of matter that does not emit or absorb light, making it invisible to telescopes. However, its presence can be detected through its gravitational effects on visible matter. It is believed that dark matter plays a significant role in galactic motion, as it makes up about 85% of the total mass of the universe.
Studying galactic motion can provide valuable insights into the structure and evolution of the universe. By analyzing the movements of galaxies, scientists can better understand the distribution of matter and energy in the universe, the formation and growth of galaxies, and the overall expansion of the universe.
