Today the Large Hadron Collider at CERN restarts doing its business: colliding particles. How this works is best explained in this video from PhD Comics. As the video says, having energy is like having money: you can buy stuff. It’s like going to a restaurant and being able to buy dishes you never had the money for; the nice thing is that you do not know what those dishes are: it is as if the ingredients had not existed before you had enough money to order those dishes.
And that is also why today is so important. Until today we have never had so much energy to magnify the behavior of Nature at very small distance. Such a behavior has only been present once in the history of the Universe, some 14 billion years ago, when the cosmos was so young it only measured a teeny tiny speck, smaller than anything you have a feeling for.
So today CERN brings us back to those times, to see what was there before our atoms even existed. Today we go witness an untold chapter of the tale of our Universe. Today we travel back in time, today we make history!
