Ever feel like you're drawn to something inescapable? That's similar to a gravity well! Imagine space as a stretched-out sheet, and massive objects like planets and stars create dips in it. These dips are gravity wells. Anything that gets too close rolls down towards the object at the bottom.
The deeper the well (meaning the more massive the object), the harder it is to escape. Earth's gravity well is substantial, keeping us firmly grounded. Black holes, on the other hand, have infinitely deep wells – nothing, not even light, can escape their pull once it crosses the event horizon.
Understanding gravity wells helps us understand how planets orbit stars, how galaxies are formed, and even the strange behavior of black holes. So next time you stumble, remember you're just experiencing the pull of Earth's ever-present gravity well!
