Mysterious Dark Matter and Dark Energy

  The fact about the universe states that the universe contains mysterious dark matter and dark energy, which make up around 95% of its total mass-energy. This is an intriguing and still largely unsolved aspect of cosmology.

Dark matter is a type of matter that does not interact with light or other forms of electromagnetic radiation, so it cannot be directly observed. However, its existence is inferred by its gravitational effects on visible matter, such as stars and galaxies. Dark matter is believed to be much more abundant than visible matter, making up around 27% of the total mass-energy of the universe.

On the other hand, dark energy is an even more mysterious component of the universe. It is thought to be a type of energy that is driving the accelerating expansion of the universe, but its exact nature is not well understood. Dark energy is estimated to make up around 68% of the total mass-energy of the universe.

Despite their mysterious nature, the existence of dark matter and dark energy have been inferred through a variety of astrophysical observations, including the cosmic microwave background radiation, the rotation curves of galaxies, and the large-scale distribution of galaxies in the universe. Understanding the nature of dark matter and dark energy is one of the biggest challenges facing cosmologists today, and could potentially revolutionize our understanding of the universe.
