A new study suggests that invisible clumps of dark matter roaming the universe may be disrupting binary stars, offering scientists a potential way to reveal the elusive entity’s true nature. Despite mounting evidence for dark matter, its exact nature remains a mystery, with scientists exploring alternative models beyond weakly interacting massive particles (WIMPs). Among these models is the ultralight dark matter particle, which possesses wave-like properties and can form giant, invisible waves called solitons.
