Anti-matter Content of the Tunguska Meteor

COWAN et al.1 have advanced the hypothesis that the 1908 Tunguska meteor explosion resulted from the anti-matter content of the meteorite. Although their analysis indicates a probable upper limit of 1/7 for the anti-matter content of the Tunguska meteor, this result depends to a large extent on the validity of certain assumptions used in the calculations.

A Meteor's Flash and Explosion

AT 8.52 p.m. (Dublin time) of yesterday, Tuesday, September 13, my wife and I while walking home were startled by a sudden bright flash like lightning, but slower and more regular in its movement. Simultaneously an intensely brilliant meteor shot majestically across the sky from north-north-west towards south-south-east, passing near, but to the eastward of, the zenith in its route. It seemed to take its origin from between the Pointers and the constellation Perseus, and died out at a height of 25° or 30° above the horizon.
