Here is a simple expression of what LHC and CERN stands for.
Theory
You are seeing a house. You wanted to know it is made of what material. You have two practical options. One is to ask the maker and the other is to break the walls and see the building materials. (In fact, there is one more way. Just leave these two ideas and simply start making theories on the building blocks of the house like most philosophers do
)
You don't know who made this house. Then what is the other option? Break it and watch.
Practice
Think of a small sugar cube as house and you wanted to know with what it is made. On examination, you learned that it is made up of carbon, hydrogen and oxygen atoms (C6 H12 O6). Now the question is that what makes a carbon atom? (Of course, you can go for other two also). It is made up of protons, neutrons and electrons according to the present scientific knowledge. Now you are interested in proton only. What makes a proton? We will call them with many different names, say X and Y. Now you think about X (or Y). What makes this stuff?
Thinking why we have to question that further? It is the basis of science and reasoning. You must be always ready to change even your very basic beliefs about the universe when the right time comes.
So what with CERN and LHC?
They are doing the above said experiment in a real laboratory setup. They use proton beams (lead ions) and hope to find out what makes a proton.
So what makes a proton?
Wait untill we are able to make another LHC hopefully by CERN itself in future.
And finally?
