If dark matter is evenly distributed throughout the galaxy then how much should be within the orbit of neptune?
Dark matter is a type of matter that does not emit or absorb light, making it invisible to telescopes. It is believed to make up about 27% of the universe and has a gravitational pull on other matter, including stars and galaxies. While dark matter does not directly affect the solar system, its gravitational pull can influence the orbits of planets and other objects within the system.
Scientists use a variety of methods to study dark matter within the solar system. One method is to observe the effects of dark matter on the motions of stars and galaxies. Another method is to look for the gamma rays produced when dark matter particles collide and annihilate each other. Additionally, scientists are conducting experiments with detectors placed on Earth, searching for dark matter particles passing through our planet.
It is currently unknown if dark matter is evenly distributed within the solar system. Some theories suggest that dark matter is distributed in a smooth halo around the galaxy, while others suggest that it may clump together in certain areas. More research and data is needed to fully understand the distribution of dark matter within the solar system.
While dark matter is a significant component of the universe, it is currently not possible to harness it for energy. Dark matter particles are difficult to detect and interact very weakly with regular matter, making it challenging to harness its energy. However, scientists continue to research and explore the potential applications of dark matter in the future.
Dark matter's weak interactions with regular matter make it unlikely that it would have a direct impact on the Earth or other planets within the solar system. However, its gravitational pull can indirectly affect planetary orbits and potentially contribute to the formation and evolution of the solar system. Further research is needed to fully understand the effects of dark matter on the solar system.
