CERN

The world’s most astonishing science experiment at CERN explained.

At the borders of France and Switzerland lies CERN, humanity’s grandest scientific venture. Deep underground, there stretches a 27-kilometer loop beneath local communities. Within this loop, scientists have constructed a large, blue tunnel that one could crawl through. Inside this tunnel, they’ve installed two pipes kept colder and emptier than outer space. Through these pipes, tiny particles, smaller than atoms, are propelled in opposite directions. Accelerating relentlessly, they reach speeds nearing that of light before colliding with tremendous force.
