“The largest prime number in the world”

Investigator Leslie Lamport writes: ” I heard this today on public radio’s Marketplace:

“A discovery of a lifetime (at least for the math geeks among us):
the largest prime number in the world.”

“This raises the interesting question of which prime numbers are in the world, and which only occur elsewhere.”

Other news outlets are reporting the same thing. The Kansas City Star goes farther:

“In the last seven years the University of Central Missouri has found the largest prime number in the world three times.”
