Dark Matter
Dark matter is an invisible, non-luminous substance that makes up about 85% of the universe's matter, inferred from its gravitational pull on visible objects like galaxies and galaxy clusters. It doesn't interact with light or electromagnetic forces, serving as a cosmic scaffolding that helps explain phenomena such as the rotation speeds of galaxies and the large-scale structure of the universe, though its fundamental composition remains a tantalizing enigma for physicists today.
Did you know?
Despite being essential to our understanding of the universe, dark matter has never been directly observed or detected in a lab, with experiments like the Large Hadron Collider failing to find evidence of its particles after billions of dollars and decades of research. This elusive stuff is estimated to make up 27% of the universe's total mass-energy, potentially consisting of exotic particles that could rewrite physics if ever identified.
