Using space telescopes like Fermi to look for gamma rays or antimatter produced when dark matter particles annihilate each other in deep space.
Massive concentrations of dark matter warp the fabric of space-time. Light traveling from distant galaxies bends around this invisible mass on its way to Earth, creating visual distortions that allow scientists to map where the dark matter resides.
Unknown; it is not made of the same protons, neutrons, and electrons (baryonic matter) that make up stars, planets, and human beings. La materia oscura
A hypothesized type of neutrino that does not interact via the weak force at all, making them harder to detect than regular neutrinos. 🛰️ Current Search Efforts
Scientists deduce the presence of dark matter by observing its immense gravitational pull on visible cosmic structures. Key lines of evidence include: Using space telescopes like Fermi to look for
In the 1970s, astronomer Vera Rubin discovered that the outer edges of spiral galaxies rotate just as fast as the centers. According to standard physics, the outer edges should fly apart unless held together by a massive, unseen halo of matter.
While many theories have been proposed, the exact identity of the dark matter particle remains undiscovered. The most prominent candidates include: Unknown; it is not made of the same
is one of the most profound mysteries in modern astrophysics and cosmology. Though it makes up about 27% of the universe's total mass-energy budget —outmassing normal, visible matter by a ratio of roughly 5 to 1—we cannot see it directly. 🌌 What is Dark Matter?
