Heya! I need some good links to articles on dark matter that are easy to understand and are worth reading. Stuff on neutrinos,, hot dark matter, cold dark matter...and mass to light ratios. tanxy.
Dark matter is a type of matter that makes up about 85% of the total matter in the universe. It does not emit or absorb light, making it invisible to telescopes and other instruments used to study the universe.
Regular matter, or baryonic matter, is made up of particles such as protons, neutrons, and electrons. Dark matter is believed to be made up of non-baryonic particles, which do not interact with light or other forms of electromagnetic radiation.
Scientists study dark matter through its gravitational effects on other objects in the universe. By observing the way galaxies rotate and how light bends around them, scientists can infer the presence of dark matter.
Some theories suggest that dark matter is made up of weakly interacting massive particles (WIMPs), while others propose that it is composed of axions, a type of hypothetical particle. Other theories suggest that dark matter could be made up of primordial black holes or other exotic particles.
Studying dark matter is important because it can help us better understand the structure and evolution of the universe. It can also provide insights into the fundamental laws of physics and potentially lead to new discoveries and technologies.
