Convection is a common process in nature, and occurs when warmer air or liquid lies under a cooler layer. This is what happens in a coffee cup: the coffee on top is cooled by evaporation, and since cooler is also heavier, gravity pulls it toward the bottom.
In the Western Pacific around New Guinea, there’s a watery hill almost 250 feet high. This isn’t a hill on the ocean floor, it’s a hill in the ocean’s surface itself.
Earth’s gravitational field is always pulling us toward the center of the Earth.
The Appalachian Mountain range has a strange bend in it caused by the gravitational pull of certain underground rocks.
Galaxies such as ours probably host several black holes. Not only that, but some of these black holes likely wander around the galaxies’ edges.
Fountain pens use four components to get ink to flow.
Our current jetpack technology only allows for a dangerous thirty-second ride.
We explain the difference between a scientific law and a scientific theory.
