We construct the first four-dimensional multi-black hole solution of general relativitywith a positive cosmological constant.
The solution consists of two static black holes whose gravitational attraction is balancedby the cosmic expansion.
These static binaries provide the first four-dimensional example of non-uniqueness ingeneral relativity without matter.
