Large Hadron Collider


The LHC is the culmination of many years of work by many different scientists, no one person invented it. 

First of all lets know a little about "LHC"

 * The Large Hadron Collider is the world’s most powerful particle accelerator and it’s about to start operating in a tunnel that runs beneath parts of Switzerland and France. Operated by CERN – the European Organisation for Nuclear Research – the LHC will produce very high-energy particle collisions.
If you want to know how the molecules that make up your body stick together in the way they do; how the sun shines; why the sky is blue; why water is a liquid at the temperatures found on Earth or even why you don’t fall through the floor when your atoms are mostly empty space — the answers are contained within the equations of the Standard Model.

How big is the LHC........?

* It’s 27 km in circumference.

It is the most accurate and successful description of the natural world we have, and as such it is one of the great achievements of 20th Century science.
It does, however, make a very weird prediction that, until yesterday, was merely conjecture.
The Standard Model says that empty space is not empty. Instead, it is crammed full of Higgs particles.
Every little cube of space in front of your eyes now, every little cube of space inside your body and every little cube of space everywhere in the universe is literally full of them.

The reason you are solid, at the deepest possible level, is because the particles that make up your body are constantly bumping into the Higgs particles, zigzagging their way through the universe and in doing so acquiring mass.
 
If they didn’t do this, you wouldn’t exist
.

So how did these Higgs particles get there?


They are what is called a condensate, and their emergence is similar to the appearance of ice crystals on a cold window pane on a winter’s night.

As the universe cooled after the Big Bang, the Higgs particles condensed seemingly “out of nothing” in the same way that the ice on your window appears “from thin air”.

The ice doesn’t really appear out of nothing, of course. What happens is that as the temperature drops, it becomes favourable for the water droplets in the air to change into ice.
