What Is The Universe Made

The composition of the universe is a complex and fascinating topic in cosmology. According to our current understanding, the universe is primarily composed of the following components

Dark Matter: Dark matter is a mysterious, invisible substance that makes up a significant portion of the universe's mass. It does not interact with light or other forms of electromagnetic radiation, which is why it's called "dark." Its presence is inferred from its gravitational effects on visible matter, such as galaxies and galaxy clusters. Dark matter is believed to play a crucial role in the structure and evolution of the universe.

Dark Energy: Dark energy is another mysterious component of the universe. It is thought to be responsible for the accelerating expansion of the universe. Unlike dark matter, dark energy is not a form of matter but rather a property of space itself. It exerts a repulsive force that counteracts the attractive force of gravity, leading to the universe's expansion.

Ordinary Matter: Ordinary matter, also known as baryonic matter, includes all the visible matter in the universe, such as stars, planets, galaxies, and everything made up of atoms. This accounts for only a small fraction of the universe's total mass-energy content, roughly around 4-5%.

In summary, the universe is primarily made up of dark matter and dark energy, which together constitute the vast majority of its content. Ordinary matter, including everything we can see and interact with, makes up a relatively small portion of the universe. Understanding the nature of dark matter and dark energy remains one of the most significant challenges in modern cosmology and astrophysics
