Show Gravity Slowly Changing, Russ Scientists Discover Tlie force of gravity, which keeps rocks, houses, and men from flying off tlie rotating earth like water or mud flies from the rapidly turning wheels of an nuto, is changing noticeably no-ticeably In some places on our globe. A Soviet scientific expedition In the Caucasus has found unmistakable unmis-takable evidence in that region that over a period of years tlie pull at tlie earth's center on all matter .around It has varied. Objects whose mass has remained identical have fluctuated In weight. Since the pull of gravity comes from exactly exact-ly the center of the earth's total mass and becomes greater as this center is approached, it Is thought the variation detected must be due to gigantic shifts of matter under the earth's crust which result In moving the earth's center of gravity. grav-ity. It can easily be seen how such shifts would affect the weight of objects ob-jects when it is understood that the weight of anything is greater,, at the bottom of a mine than it Is at the surface of the earth. Likewise a man weighs more standing at the North or South pole than lie would weigh at the equator, partly because on the flattened pole he is nearer the center of the earth. Pathfinder Magazine. |
