A huge ‘bridge’ of invisible ‘dark matter’ has been detected holding two galaxy clusters, Abell 223 and Abell 222, together.
The filaments are thought to be a ‘glue’ that holds huge galaxy clusters together, but dark matter is extremely difficult to detect, as it does not emit any radiation.
Instead, the ‘bridge’ was detected by the gravitational ripples it caused in space, distorting the light from nearby stars as it arrived on Earth.
