What is the Largest Scientific Instrument in the World?

Answer:

The world's largest scientific instrument (and arguably the world's largest machine) is the Large Electron Positron Collider. It is a circular tube 3.8 m (12 ft 6 in) in diameter and 27 km (17 miles) in circumference. It is situated in a giant donut-shaped tunnel 100 m (330 ft) below the area around the Swiss-French border in Geneva. The machine began operating in 1989 and was officially closed down at 8 am on November 2, 2000. It was used to examine the smallest particles of matter by accelerating electrons and positrons that collided with each other. The collisions produced tiny sub-atomic particles and enabled physicists to study the fundamental nature of the universe.
