Every 27 Million Years

How long do we have left?

It appears that Nemesis may be off the hook, however...

BTW, I wonder if I should start working on bomb shelter before the next mass extinction hits.

Postulated extinction cycles
Extinction event - Wikipedia, the free encyclopedia

It has been suggested by several sources that biodiversity and/or extinction events may be influenced by cyclic processes. The best-known hypothesis of extinction events by a cyclic process is the 26M to 30M year cycle in extinctions proposed by Raup and Sepkoski (1986).[48] More recently, Rohde and Muller (2005) have suggested that biodiversity fluctuates primarily on 62 ± 3 million year cycles.[49]

When is the next one due?
