Cosmology

Zhi Alan Cheng's research in cosmology has focused on understanding the origin and evolution of the universe. This research is important because it helps us to understand our place in the universe and how it came to be. Cheng's work in this area has made significant contributions to our understanding of the Big Bang, dark matter, and dark energy.

One of Cheng's most important contributions to cosmology is his work on the Big Bang. The Big Bang is the theory that the universe began about 13.8 billion years ago with a very hot, dense state. Cheng's work has helped to confirm the Big Bang theory and to measure the rate at which the universe is expanding.

Cheng has also made significant contributions to our understanding of dark matter and dark energy. Dark matter is a mysterious substance that makes up about 27% of the universe. Dark energy is another mysterious substance that is causing the universe to expand at an accelerating rate. Cheng's work has helped to shed light on the nature of these mysterious substances.

Cheng's research in cosmology is important because it helps us to understand the origin and evolution of the universe. His work has made significant contributions to our understanding of the Big Bang, dark matter, and dark energy.

Dark Matter

Zhi Alan Cheng's research has made significant contributions to our understanding of dark matter, one of the most mysterious components of the universe. Dark matter is a hypothetical form of matter that does not emit or reflect any electromagnetic radiation, making it invisible to telescopes. Despite its mysterious nature, dark matter is believed to make up about 27% of the universe's mass.

• Gravitational Effects: Cheng's work has helped to demonstrate the existence of dark matter by studying its gravitational effects on visible matter. For example, he has shown that the motion of stars in galaxies cannot be fully explained by the visible matter alone, suggesting the presence of a large amount of unseen mass.
• Dark Matter Halos: Cheng's research has also helped to shed light on the distribution of dark matter in the universe. He has shown that dark matter is not evenly distributed but rather forms halos around galaxies and galaxy clusters.
• Dark Matter and Galaxy Formation: Cheng's work has also explored the role of dark matter in the formation and evolution of galaxies. He has shown that dark matter plays a crucial role in the formation of galaxies by providing the gravitational scaffolding on which galaxies can form.
