Earth-15 is one of the many universes in the multiverse. For unspecified reasons in 1986 it became a dead Earth.[1]
History
At some point, this universe became a dead Earth.
In early 2018, Cisco Ramon vibed all of Neil Borman/Fallout's nuclear radiation to this Earth.[2]
A couple months later when Team Flash was dealing with the threat of a nuclear bomb exploding in Central City, Cisco suggested breaching the nuke to to Earth-15 before it detonated. However, because they'd been forced to operate in Flashtime to stop the nuke, this proved impossible as Cisco was ill-equipped to open breaches while moving at such high speeds.[3]
Over a year later when Team Flash needed to stop a virus made from the meta-human cure, Barry Allen suggested taking the virus to Earth-15.[4]
