A new study suggests that dark matter may interact with regular matter through forces beyond gravity, based on the uniform distribution of stars in ultrafaint dwarf galaxies.
Dark matter, thought to be five times more massive than regular matter, helps hold galaxies together and explains puzzling star movements.Why is the dark matter called “dark”? Is it because it holds some evil cosmic forces or shady secrets that scientists don’t want us to know? Well, such fancy assumptions may sound intriguing to a conspiracy theorist, but they’re far from the truth.
Dark matter does have mass though, and mass creates gravity. This means dark matter can pull on or interact with regular matter and vice versa. Such interactions are rare, and gravity remains the only known force that makes the two forms of matter interact.It is believed that dark matter constitutes roughly five times the mass of regular matter in our universe. It helps keep galaxies together and explains some movements of stars that wouldn’t make sense based on visible matter alone.

Origins of variability in X-ray photons from a symbiotic binary star as revealed by dimensionality reductionSymbiotic binary stars are a type of binary star system that consists of a compact star (such as a white dwarf) and a red giant star. In these systems, a compact star accretes materials from a red giant star and produces soft X-ray photons.
