Carl .’s Cosmic Breakthrough

Contents

Dirac’s colleagues did not believe in antimatter when he first published his radical ideas. Then, in 1932, physicist Carl Anderson was examining the tracks made by cosmic rays in a cloud chamber, an instrument that detects high-energy particles following the trails they leave as they pass by steam wave. Its path was bent in a magnetic field indicating that it was positively charged. He named it the positron. This is Dirac’s antielectron.

Create antimatter

Today, antimatter is mainly found in cosmic rays – high-energy extraterrestrial particles that form new particles as they enter Earth’s atmosphere. For more than 50 years now, laboratories such as the European Organization for Nuclear Research (CERN) located on the Swiss-French border near Geneva have regularly produced antiparticles. In 1995, CERN became the first laboratory to artificially create anti-atoms.

Destruction

One of the more impressive finds – explored in many sci-fi adventures – is that antimatter and matter explode on contact. Because these annihilation produce energy in the form of radiation and particles, scientists can use instruments to measure the “wreckage” of these collisions. Even so, scientists still send observatories into space to look for them, just in case.

Antimatter and the Big Bang

At that time, matter and antimatter existed in equal amounts because the law of nature required matter and antimatter to be formed in pairs. there are 1,000,000,001 seeds. Matter and antimatter cannot tolerate each other’s presence. Instead, they annihilate each other in a flash whenever they come into contact. All that’s left behind is the tiny fraction of matter that goes on to make up stars, galaxies, planets, and even you. Some think it broke the laws of physics in those first few seconds. Some speculate that annihilation never happened and that antimatter lives somewhere in a part of the universe that we can’t see.

Where is antimatter?

Most scientists believe that slight differences in how matter and antimatter interact with the forces of nature could explain why the universe prefers matter. The “violation of charge parity”, which is an example of the type of asymmetry between particles and their antiparticles, describes how they decay. Physicists have confirmed the existence of this asymmetry in the behavior of exotic particles known as kaons and B mesons, but they have never found it to be common enough to explain why the universe is broken. dominated by matter. , is a base called LHCb. It is one of four large particle physics experiments that monitor the collisions of particles in the Large Hadron Collider at CERN, a particle physics laboratory located on the border between Switzerland and France near Geneva (see website LHC).
