Hi All: More pesky "changing speed" of earthquake waves.... Looks like they are stuck on the wrong conclusion too...but great sleuthing nevertheless ! Just my .02 worth.... (& search archives on 'conumdrum') ---------------------------------------------- 360 Mile Diameter Spherical Core Found At Center Of Earth By William J. Cromie for The Harvard Gazette 10-15-2 LOS ANGELES -- An odd, previously unknown sphere, some 360 miles in diameter, has been found at the bottom of the Earth. It was detected by a Harvard professor and a graduate student who patiently examined records of hundreds of thousands of earthquake waves that passed through the center of the planet in the past 30 years. "It may be the oldest fossil left from the formation of Earth," says Adam Dziewonski, Frank B. Baird Jr. Professor of Science. "Its origin remains unknown, but its presence could change our basic ideas about the origin and history of the planet."
