At this point, maybe this is the only thing that can bring us together.
Over the next 300 million years, all the Earth’s continents will smash together and form a new supercontinent called Amasia, closing the Pacific Ocean in the process.National Science Review"Over the past two billion years, Earth’s continents have collided together to form a supercontinent every 600 million years, known as the supercontinent cycle," said study lead author Chuan Hung in a
. "This means that the current continents are due to come together again in a couple of hundred of million years’ time."To establish a timeframe, the researchers used 4D geodynamic modeling of the Earth’s tectonic plates, determined to find out why previous supercontinents formed in completely different ways.
Of those ways, introversion is one of two main models, and occurs when continents close over an internal ocean that was formed when the previous supercontinent broke apart. On the opposing end is extroversion, which has the continents closing over the external, former superocean. If that bit of rocky history could be cleared up, the researchers could better predict the next supercontinental assembly.
"The resulting new supercontinent has already been named Amasia because some believe that the Pacific Ocean will close when America collides with Asia," said Huang. "Australia is also expected to play a role in this important Earth event, first colliding with Asia and then connecting America and Asia once the Pacific Ocean closes."
If they hold up, these are remarkable findings that provide a glimpse of the planet’s future. But it's still only
