Approximately 27% of the universe is made up of dark matter, a mysterious and invisible substance that does not emit, absorb, or reflect light, making it impossible to detect directly with current telescopes. Although it cannot be seen, its presence is inferred through its gravitational effects on visible matter, such as stars and galaxies. Dark matter plays a crucial role in the formation of large-scale structures in the universe, influencing the way galaxies are held together and how they collide and merge. Scientists estimate that dark matter outweighs ordinary matter by a factor of five, making it a key component in our understanding of the cosmos and an area of intense research as physicists strive to unlock its secrets and understand its true nature.
