DARK ENERGY and DARK MATTER

Dark matter and dark energy are two of the most mysterious and intriguing topics in modern physics. Despite their apparent invisibility and elusiveness, scientists believe that they make up the vast majority of the universe. 

Dark Energy and Dark Matter

DARK MATTER:

 Dark matter is a type of matter that cannot be detected through electromagnetic radiation because it does not interact with light or any other form of electromagnetic radiation. It is believed to be present in the universe because of the gravitational effect it has on visible matter. In other words, visible matter seems to be affected by a gravitational force that is much stronger than can be accounted for by the visible matter alone.

This suggests that there must be some invisible matter that is exerting the additional gravitational pull. The existence of dark matter was first proposed in the 1930s, but it was not until the 1970s that its existence was widely accepted. 

 Scientists believe that dark matter makes up about 27% of the universe, while visible matter makes up only about 5%. The rest of the universe is believed to be made up of dark energy, which is even more mysterious than dark matter.

Dark Energy

 Dark energy is a type of energy that is thought to be responsible for the accelerating expansion of the universe. In other words, the universe is expanding at an ever-increasing rate, and this expansion is thought to be driven by the presence of dark energy. Like dark matter, dark energy cannot be detected directly. Instead, its existence is inferred from the observed expansion of the universe. 

 Scientists believe that dark energy makes up about 68% of the universe, which means that only a tiny fraction of the universe is made up of visible matter. This has led some scientists to suggest that we are living in a "dark universe," where most of the matter and energy is invisible and undetectable.

 Despite the fact that dark matter and dark energy are still largely mysterious, scientists continue to study them in order to gain a better understanding of the universe. They are using a variety of methods to try to detect and measure dark matter and dark energy, including gravitational lensing, which involves observing the distortion of light as it passes through a massive object, and the observation of the cosmic microwave background radiation, which is the afterglow of the Big Bang.
