When you were a kid, did you ever try to crash two toy cars to see what happened? If so, you will understand the basic principle of a large particle accelerator (LHC).
LHC is a 27km long tunnel built by the European Nuclear Research Center (CERN) in the suburbs of Switzerland. Its task is to create collisions between two beams of particles moving at the speed of light. The data obtained after the collision will help researchers find the structure and origin of the universe.
Because of such a special responsibility, the LHC cannot avoid criticism and concerns about its safety.
CERN is creating a antimatter bomb?
Anyone who has read or watched the film adapted from Dan Brown's ' Angels and Demons ' novel knows the plot revolves around stealing a antimatter bomb from CERN in order to conspire to erase the Vatican. Surely you will worry how much this situation has in fact happened? It has some mistakes regarding the use of antimatter, both as a source of energy and as a weapon.
It is true that when antimatter is exposed to ordinary matter, both will cancel each other out and release energy. But CERN has confirmed that this energy is so small, so small that it almost does not exist. Scientists only recovered 1 part of the energy they invested in the collision when antimatter clashed with its " rival ". And with concerns about the ability to build a antimatter bomb, CERN said, if with current technology and work schedule, it would take them billions of years to produce enough antimatter to cause out an explosion equivalent to a nuclear bomb explosion.
Will reconstructing the black hole destroy the Earth?
When scientists at CERN said they could make microscopic black holes between particle collisions, many people were worried that the black hole would swallow Earth in the blink of an eye. According to Einstein 's theory of relativity , there are actually several possibilities for recreating black holes, but the good news is that these microscopic black holes will disappear almost immediately after forming. And if it lingers for a longer time, it will take billions of years for the tiny size to swallow a tiny grain of sand.
This also means that there is no way LHC will destroy the Earth.
Strange matter wiped out the universe?
In the last few years, researchers at Brookhaven Laboratories, New York, have created foreign matter at an unprecedented high temperature on Earth. Strange material theories say that it is 10 million times heavier than lead and was born in the Big Bang. From this result, it is concerned that the LHC may inadvertently create very small foreign matter particles, which in turn will then convert ordinary matter around it into objects. another strange substance, and it only takes a billionth of a second to make this transformation line transform the entire planet.
However, strange material assumptions are still speculative, so there is absolutely no practical basis to assume that the LHC will destroy this planet.
