Before CERN had the Large Hadron Collider (LHC), that famous tunnel under France and Switzerland was home to the Large Electron–Positron collider (LEP). It was switched on 30 years ago in 1989. and the above video shows how the 27 km long tunnel was created in what is surely an engineering marvel of the 20th century.

The LHC will run for a few more decades but the big question is whether an even larger 100 km collider will be built at CERN in the future?

Alan Bernau runs Alan’s Factory Outlet in Luray, Virginia – supplying garages, carports and sheds. But he and his colleagues also have a keen interest in science and they have created a fantastic infographic about the composition of the universe that you can view on the company’s website.

It is called “The abundance of stuff in the universe” and Bernau told us: “It explores how much dark matter and dark energy make up the universe, as well as the elements that make up the small amount of matter scientists are able to see and study. We had a lot of fun putting it together and are proud of how it turned out.”

Other infographics made by the team include “The melting points of 80 elements, substances, and metal alloys” and “Artificial objects that humankind has left on extra-terrestrial surfaces“.
