Gravity holes: How UT's experimental mission uncovered secrets of our planet

AUSTIN (KXAN) -- A 'gravity hole' on Earth? Earlier this summer, researchers with the Indian Institute of Science published a paper exploring one of these 'gravity holes'. Found all over the planet, these are spots on the planet's surface where there is less gravity than in other spots.
