Dark Matter


Dark matter is a form of matter thought to account for approximately 85% of the matter in the universe. Its presence is implied in a variety of astrophysical observations, including gravitational effects that cannot be explained by accepted theories of gravity unless more matter is present than can be seen. …

Baryogenesis


In physical cosmology, the baryon asymmetry problem, also known as the matter asymmetry problem or the matter-antimatter asymmetry problem, is the observed imbalance in the baryonic matter (the type of matter experienced in everyday life) and antibaryonic matter in the observable universe. Neither the standard model of particle physics, nor …

The Early Universe and Matter


Lasting around 370,000 years. Initially, various kinds of subatomic particles are formed in stages. These particles include almost equal amounts of matter and antimatter, so most of them quickly annihilate, leaving a small excess of matter in the universe. At about one second, neutrinos decouple; these neutrinos form the cosmic …

Multi-messenger Astronomy


Multi-messenger astronomy is the practice of synthesizing these various messengers from violent astronomical events such as Gravitational waves, Cosmic rays, UHE neutrinos, and electromagnetic waves (gamma-ray, X-ray, Radio, etc).
