How big is the Large Hadron Collider?

The Large Hadron Collider is 8.6 千米

Introduction

Have you ever wondered about the grand scale of scientific experiments? How about one that’s almost as big as a whole city? Today, we are going to dive into the world of the Large Hadron Collider (LHC), the world’s biggest and most powerful particle collider.

What is the Large Hadron Collider?

The Large Hadron Collider is a marvel of modern science, situated deep beneath the border of France and Switzerland. It’s like an enormous underground racetrack for particles. Constructed by the European Organization for Nuclear Research (CERN), the LHC took 10 years to build, from 1998 to 2008, and involved over 10,000 scientists and hundreds of universities and laboratories from more than 100 countries.

Size and Structure

Now, let’s talk about the size of this scientific giant. The LHC is a massive tunnel, shaped in a ring, and it’s roughly 27 kilometers (or about 17 miles) in circumference. That’s longer than the entire island of Manhattan! And it’s not just long - the LHC also goes deep. It sits as far as 175 meters (or about 574 feet) below the ground. That’s deeper than the Eiffel Tower is tall!

  • The LHC is 27 kilometers in circumference. That’s like stretching a string all the way around Manhattan. - It’s buried 175 meters beneath the Earth. The Eiffel Tower could fit inside with room to spare!

Achievements

The LHC isn’t just big in size; it’s also big in scientific achievements. The first particle collisions were made in 2010, and they were done at an energy level four times the previous world record. Even more impressive, in 2012, scientists announced the discovery of the Higgs boson at the LHC. This tiny particle, often called the “God particle,” helps us understand why other particles have mass.

Upgrades and Improvements

After its initial successes, the LHC didn’t rest on its laurels. Between 2013 and 2015, the LHC was shut down for upgrades. When it started up again, it reached an energy level of 6.8 teraelectronvolts per beam, nearly double the energy of its first collisions. At the end of 2018, the LHC was shut down again for three years for further improvements, showing that even the biggest scientific projects can always get a little bit better. So, the next time you think about the Large Hadron Collider, remember - it’s not just a particle collider. It’s a giant ring buried deep beneath the earth, longer than Manhattan and deeper than the Eiffel Tower, pushing the boundaries of what we know about the universe.

Palm Jebel Ali
Palm Jebel Ali is the largest man-made island (not including islands like Flevopolder, where a region of the Netherlands was drained so there could be more land). Palm Jebel Ali is not complete. It is part of the Palm Islands and is planned to house 250,000 people!
Cruithne
Cruithne is known as Earth's second moon. It actually isn't Earth's moon. It just follows an elliptical orbit around the Sun that is near Earth's orbit, and its year is 364 days, close to Earth's year.
Central Park
Central Park, which is in New York City, is the most visited urban park in the United States! Did you know that 129[1] people actually live in Central Park? That's pretty cool!

Mount Everest
Mount Everest is the highest mountain on Earth at 8,848 meters. It is constantly growing, like children do. Not many people can climb it without using an oxygen tank.
Depth of the Mariana Trench
The Mariana Trench is a pretty deep trench. It is in the Pacific Ocean. Did you know that this lovely trench has been proposed as a site for dumping nuclear waste? That's a deep topic!
Halley's Comet
The actual size of Halley's Comet is quite small. The tail that it forms can be millions of kilometers in length! Halley's comet loses 10% of its mass for every thousand orbits.
