The 550,000 miles of undersea cables that power the internet

A planetary system of undersea cables stretches across oceans, seas, and around continents... 550,000 miles (885,139.2 kilometers) of fiber optic communications cables that power the internet and more. The first was l...

Building the solar system to scale in the Nevada desert

"Every single picture of the solar system that we ever encounter is not to scale. If you put the orbits to scale on a piece of paper, the planets become microscopic and you won't be able to see them. There is literall...
