However, fungi don’t stay still. Mycorrhizal hyphae die back and regrow so rapidly—between ten and sixty times per year—that over a million years their cumulative length would exceed the diameter of the known universe (4.8 × 1010 light years of hyphae, versus 9.1 × 109 light years in the known universe).
