"Scientists had theorized that as the core of Mercury cools, it contracts, and the whole planet shrinks."
Messenger has sent back pictures showing 'wrinkles' on the surface of the planet and what scientists are calling "The Spider", a series of wrinkles that radiate out from a crater-like formation, most likely what used to be a volcano.
Why is this significant? Because this is a side of Mercury that has never been seen before. These pictures throw off all theories that have been known about the planet. It's making everyone reassess.
It also proves how little we know of the universe itself. All we can do is make educated guesses at most things-sometimes it turns out right, sometimes not. And, sometimes, what we thought was right turns out not to be right at all, but so far from what we originally thought.
There's just so much we don't know.
