The Large Hadron Collider is the most expensive and complex scientific experiment ever built. This video shows how the contraption accelerates and slams together subatomic particles and what comes out of the collision.

   Although the clip was interesting to not only watch, bit clear information was given.
   
   However, the side splitting laughter occurred when the credits rolled at the end of the clip.
   
   Watch the clip, especially the credit roll and read the sentence about particle abuse . . I hope the clip producers were having some fun, but if it’s a serious statement mandated by some authority, then I strongly suggest that somebody in charge needs to take a long vacation.

   The narrator's voice travels almost at the speed of the particles in the collider.

   1). Energy of Avogadro number of Curie photon or NAф photon at a distance of 1 meter is important. This is 165 Mev. If this distance consider as 1 cm, then we get 1.65 Tev. The CERN going to estimate the mass of Higgs particle and announced that mass of Higgs particle near by 126 Gev or 0.126 Tev [1]. My calculated value is about 13 times larger than the experimental value, though 126 Gev is not confirmed.
   2). During experiment, different type of mass of particles will be observed into the CERN equipments. When energy will differ, then the mass will differ. But there is a good relation between one to next particle. All sub-atomic particles, quarks are interrelated. Its relation will depend on the CURIE Particle which is unknown to scientific world. The energy of Curie particle is 165 Mev. The mass of Graviton particle is too small than a photon particle. Graviton particle is responsible to give birth a photon particle. Again, graviton particle is creating from black particles, so, in our universe, all stars, galaxies, particles are interrelated. All facts are written in the book Complete Unified Theory (Pages- 424, 1998).

   Somebody should tell the webmaster that the video is broken

   Someone might think "no particles were harmed" could be serious?

   Two gluons collide to create two gluons and two more particles? It seems the two particles would combine and annihilate each other so that the quantity of entities before and after collusions remains same. But if they do not combine then we have a way of splitting "nothingness" into two "somethings".
   
   (-- two 'opposite' somethings)

   I liked the video and the explanation, but someone should tell Rose Eveleth that talking so fast detracts, not adds, to the appeal. A more measured and more natural speaking cadence would allow the viewer to absorb more of the message. As it is a good schematic diagram and cartoon is wasted with the distraction of speed talking.
