1. How good is the Large Hadron Collider? In short, it may be the greatest experimental tool in the world. It is essentially a 26.6 km long particle accelerator. In circular orbit, it allows scientists to accelerate protons to near the speed of light and make them collide. With the help of this machine, scientists clearly observed the formation of quark-gluon plasma, confirmed the existence of particle supersymmetry, and discovered the Higgs boson, a god particle that won the Nobel Prize in physics for its discovery. You already know its ability to find and observe microscopic particles.
Second, in this ghost hunting experiment, scientists first analyzed the possible forms of ghosts. If a ghost exists, it must carry some information, and if this information wants to stay in this world, it must have some medium as a carrier. This carrier can be energy, substance or even a mixture of the two. The first thing to look for is the ghost in the form of energy. If the ghost exists in this form, its every action must consume energy, even produce sound and light, all of which can be easily detected by LHC.
As a result of the experiment, nothing was found. Scientists try to prove the existence of ghosts from a physical point of view. Unfortunately, the most advanced instruments in the world have not found any special ghost particles. Moreover, there are no known particles that can simulate the existence of tentacles with mathematical models like ghosts, resulting in reasonable correlation. In other words, ghosts do not exist.
In fact, scientists have long pointed out that the existence of ghosts violates the laws of thermodynamics, and this alone is enough to prove that ghosts do not exist. If a ghost must live in the cracks, it probably exists in the form of imagination. According to statistics, more than 40% of British people believe in ghosts. In the United States with advanced technology, this figure is as high as two-thirds. Perhaps the public will find Nie Xiaoqian's story more interesting than the discovery of the collider.
