Dark matter refers to substances that do not interact with electromagnetic radiation and whose existence can only be determined by their gravitational effect on other substances.

Dark matter is a type of matter that makes up about 85% of the universe. There is no definitive information yet about the nature of dark matter. It is thought that dark matter may be a new type of fundamental particle or a new configuration of known particles.

Direct observation of dark matter or its constituent particles is challenging due to their non-interaction with electromagnetic radiation. Efforts to detect dark matter focus on exploring potential effects beyond gravitational influence.

Compelling evidence supporting dark matter's existence includes the rapid rotations of spiral galaxies, surpassing the gravitational impact of visible matter.

Other indicators involve the movements of galaxy clusters, the distribution of heat and radiation post-big bang, and the expansion rate of the universe.

Notably, observations at the center of the Milky Way reveal stars and gas orbiting faster than expected, hinting at the presence of matter with a more significant gravitational effect than visible matter—a phenomenon not explained by a black hole composed of visible matter.

Despite ongoing research, the nature of dark matter remains uncertain. Proposing potential properties, it is envisioned as a substance with no electromagnetic interaction, possessing greater gravitational influence than visible matter and contributing substantially to the universe's composition.

Research on dark matter persists, driven by the prospect that understanding its nature holds crucial insights into the universe's formation and evolution. As dark matter comprises a substantial portion of the cosmos, ongoing efforts aim to unravel its mysteries and shed light on the fundamental forces shaping our universe.

If dark matter is a new type of fundamental particle, this particle would be expected to interact with other forces in addition to the gravitational effect. If dark matter is a new configuration of known particles, it is possible that this configuration interacts with other forces in addition to the gravitational effect.

To prove the existence of dark matter, it is necessary to directly observe dark matter or detect particles composed of dark matter. However, since dark matter does not interact with electromagnetic radiation, it is very difficult to observe it directly.

In order to detect particles consisting of dark matter, it is being investigated whether dark matter has any effect other than its gravitational effect.

The most important evidence showing the existence of dark matter is the rotations of spiral galaxies. Spiral galaxies have been observed to rotate much faster than the amount of visible matter.

This observation indicates the existence of matter that has a greater gravitational effect than visible matter.

Other evidence showing the existence of dark matter are: Movements of galaxy clusters, distribution of heat and radiation after the big bang, expansion rate of the universe after the big bang.

For example, at the center of the Milky Way galaxy there is a black hole composed of visible matter. The gravitational effect of this black hole causes the stars and gas of the Milky Way galaxy to orbit around it.

However, the stars and gas of the Milky Way galaxy have been observed to rotate much faster than the gravitational influence of a black hole composed of visible matter.

This observation indicates the existence of matter at the center of the Milky Way galaxy that has a much greater gravitational effect than visible matter.

Research on the nature of dark matter continues, as dark matter may hold important information about the formation and evolution of the universe.

Possible properties of dark matter are: Dark matter is a substance that does not interact with electromagnetic radiation. Dark matter has a greater gravitational effect than visible matter. Dark matter is a type of matter that makes up about 85% of the universe.

Research continues on dark matter, which is thought to constitute 85% of the universe.
