Synopsis:
The ultimate cause of the trouble is revealed to be an experimental space-warp machine of Ray Palmer's assistant. The gathered JLA and JSA hold the Anti-Matter Man at bay until The Atom (Ray) and The Spectre can re-align the two Earths to their proper times and spaces -- The Atom (Ray) turning off the machine, and the Spectre using his enormous magicks to realign the Earths back to their proper spots.
