Understanding the problem

Read the background

Planar nearest-neighbor first-passage percolation with iid nonnegative nonatomic edge weights almost surely has no doubly infinite geodesic when the minimum of four independent weights has finite second moment.

Why it matters

If correct, resolves the planar no-bigeodesics conjecture under the stated moment condition.

What counts as progress

Are all bigeodesics absent in planar first-passage percolation under continuous weights?
