Dark matter is a mysterious substance that scientists have been trying to understand since the 1930s. Dark matter holds galaxies together and is spread throughout the universe. But researchers still don’t know much about it.
First, dark matter can be made up of different types of particles. They may interact with forces other than gravity. Physicists have proposed different types of dark matter, each with its own strengths and weaknesses.
WIMP is the most popular dark matter. Such dark matter can interact with any normal matter. However, detecting WIMP-type dark matter is difficult. Scientists have spent a lot of time and money trying to find this kind of dark matter. However, not much success was achieved.
There is a compact object called MACHO. This is the kind of dark matter scientists are exploring. One of the biggest challenges in studying dark matter is that it does not interact with light. Scientists have to rely on indirect evidence to study dark matter.
By studying the motion of galaxies, scientists can get an idea of dark matter. How galaxies rotate is measured. Scientists also try to find evidence of collisions between normal matter and dark matter particles. This is an important step in studying dark matter.
Finding dark matter is difficult, but scientists are still trying. Coolant tools are used in such experiments. Gaining important information about dark matter will lead to a better understanding of how the universe works at a fundamental level. As a result, new technologies and techniques for studying the universe will continue to be developed.
