India successfully launched Chandrayaan-2 orbiter mission and lunar surface spacecraft on Monday.
According to scientists at Yale University America and Eurasia will crash into each other over the North Pole in 50-200 million years time. A supercontinent last formed 300 million years ago, when all the land masses grouped together on the equator as Pangaea, centred about where West Africa is now. After looking at the geology of mountain ranges around the world, geologists had assumed that the next supercontinent would form either in the same place as Pangaea, closing the Atlantic Ocean like an accordion, or on the other side of the world, in the middle of the current Pacific Ocean. Scientists at Yale University analysed the magnetism of ancient rocks to work out their locations on the globe over time, and measured how the material under Earth’s crust, the mantle, moves the continents that float on its surface. They found that instead of staying near the equator, the next supercontinent, called Amasia, should form 90 degrees away from Pangaea, over the Arctic. How scientists say at first have to fuse the Americas together, then those would mutually migrate northward leading to collision with Europe and Asia more or less at the present day North Pole, Australia would continue with northward motion and snuggle up next to India. Scientists call this model orthoversion, as opposed to introversion, in which the supercontinent forms where Pangaea was, or extroversion, in which it moves round to the other side of the world, staying on the equator.
