I have actually, but unfortunately it doesn't say much about dark matter.PeroK said:Have you looked at Introduction to Modern Cosmology by Andrew Liddle?
Perhaps there's no much to say. Not in a textbook. It's still in the realm of speculative research, isn't it?Floyd_13 said:I have actually, but unfortunately it doesn't say much about dark matter.
B. Ryden's cosmology text has a chapter on DM that is a bit more meaty than the equivalent in Liddle, plus a scattering of relevant discussions in other places, such as in the chapter on CMB temperature fluctuations.Floyd_13 said:I have actually, but unfortunately it doesn't say much about dark matter.
Dark matter is a type of matter that makes up about 27% of the universe. It does not emit or absorb light, making it invisible to telescopes. Its existence is inferred through its gravitational effects on visible matter.
Studying dark matter is important because it is a fundamental component of the universe and plays a crucial role in the formation and evolution of galaxies. Understanding dark matter can also provide insights into the nature of the universe and its ultimate fate.
Dark matter cannot be directly observed, but its presence can be inferred through its gravitational effects on visible matter. Scientists also use techniques such as gravitational lensing and studying the rotation curves of galaxies to detect dark matter.
Some current theories about dark matter include the WIMP (Weakly Interacting Massive Particles) theory, which proposes that dark matter is made up of particles that interact weakly with normal matter, and the MACHO (Massive Compact Halo Objects) theory, which suggests that dark matter is made up of massive objects such as black holes or brown dwarfs.
Dark matter is thought to have played a crucial role in the formation of the universe after the Big Bang. The presence of dark matter helps explain the distribution of matter in the universe and the formation of large-scale structures such as galaxies and galaxy clusters.
