Just a layman's question about dark matter. Dark matter, like regular matter, is associated with the gravitational force. Dark matter attracts other dark matter as well as regular matter. Regular matter attracts dark matter also. With that said, wouldn't dark matter be all around us? Wouldn't it be part of the Earth, or at least the solar system? Also, since dark matter doesn't interact with regular matter in any way except through the gravitational force, maybe the center of planets and stars contain large amounts of dark matter? The dark matter wouldn't bond chemically to regular matter and would presumably just float on by, straight to the center of large objects. I would think this would be the case, especially since there is supposed to be at least 5 times the amount of dark matter in the universe as regular matter. I'm sure I'm missing something fundamental about the nature of dark matter, so any explanations will be appreciated. Thanks.
