Although space may appear to some to be the final frontier, scientists are still actively discovering new things about our own little planet, including the mysteries that exist beneath its surface.
A molten outer core surrounded by a highly packed ball of solid iron alloy has been widely accepted by scientists for more than half a century. However, new research provides a rare glimpse into the planet’s interior structure, far stranger than previously assumed.
Eratosthenes, a Greek polymath, made the first measurement of the distance around the Earth’s sphere more than 2,200 years ago, and it has been evident ever since that it must have a center.
For decades, we’ve known that we do not live on a disc but on a ball-shaped planet which goes hand in hand with the notion that Earth has a definite center.
