The longest path for land took longer to find needing 45 minutes. Both paths were found with the algorithm running on a normal laptop.

Back in 2012, a Reddit user posted a map claiming to show the longest straight line that could be traversed across the ocean without hitting land.

While they were at it, they found the longest straight path you could drive without hitting water.

The longest straight-line route possible without ever crossing a body of water. The algorithm groups similar paths into the same ‘branch,’ then evaluates the branches against each other.

Five years ago, a Reddit post mapped the longest continuous ocean route on Earth, following a straight line. Researchers recently proved that the calculation was correct.
