What is Dark Matter?

Dark matter is a type of matter that does not interact with light, making it invisible to telescopes. Scientists have inferred its existence through its gravitational effects on visible matter. According to current estimates, dark matter makes up around 27% of the universe. Dark matter is believed to be made up of exotic particles that have not yet been detected, which do not interact with light or any other form of electromagnetic radiation.

 

What is Dark Energy?

Dark energy is an even more mysterious substance, making up around 68% of the universe. Scientists believe it may be a form of energy that permeates all of space, exerting a negative pressure that drives the expansion of the universe. It is not yet fully understood, but it is believed to be the force behind the accelerating expansion of the universe.

 

What is "Normal" Matter?

"Normal" matter is the matter that we can see and interact with, and it is made up of atoms composed of protons, neutrons, and electrons. This matter is found in stars, planets, galaxies, and other celestial bodies. However, "normal" matter only makes up a small fraction of the universe - around 5%.

Research on Dark Matter and Dark Energy

One of the main areas of research in cosmology is the study of dark matter and dark energy and their role in the universe. Scientists are trying to understand the properties of these mysterious substances and how they interact with normal matter. They are also trying to determine their impact on the expansion and fate of the universe.

 

In recent years, several experiments and observations have provided new insights into the nature of dark matter and dark energy. For example, the Planck satellite, which mapped the cosmic microwave background radiation, provided new constraints on the properties of dark matter and dark energy. The Large Hadron Collider (LHC) at CERN is also searching for evidence of dark matter particles through high-energy collisions.
