Betulkah maklumat yang dinyatakan oleh para saintis bahawa bumi sebenarnya berbentuk seperti ubi kentang, bukannya berbentuk sfera sebagaimana yang dipercayai sebelum ini?
Scientists have unveiled the most accurate map ever produced of the Earth’s gravity. It seems it is shaped not like a sphere but a potato. A precise model of Earth’s geoid is crucial for deriving accurate measurements of ocean circulation, sea-level change and terrestrial ice dynamics. The geoid is also used as a reference surface from which to map the topographical features on the planet. In addition, a better understanding of variations in the gravity field will lead to a deeper understanding of Earth’s interior, such as the physics and dynamics associated with volcanic activity and earthquakes.
