A team of geophysicists at ETH Zurich in Switzerland has made a baffling discovery while analyzing earthquake waves to calculate the internal structures of the Earth. They found areas in our planet’s interior that appear to be the leftovers of submerged tectonic plates deep below large oceans and far away from plate boundaries — nowhere near where scientists expected to find them. It’s an intriguing finding that suggests a “lost world” may be lurking deep below the Pacific Ocean. But researchers
