This blog post explains why the Higgs boson is called the ‘God particle’ and its scientific significance in an easy and interesting way.
Confirmation of the Existence of the God Particle, the Higgs Boson
“Confirmation of the Existence of the ‘God Particle’ Higgs Boson” was a headline frequently seen on October 4, 2013. An international research team, including the University of Tokyo and the High Energy Accelerator Research Organization (KEK) in Japan, discovered the existence of the Higgs boson, and news and real-time search rankings were filled with stories about the Higgs particle. Let’s explore the Higgs boson, dubbed the “God particle,” which ignited the scientific community and earned the 2013 Nobel Prize.
What is the Higgs boson?
To understand what the Higgs boson is, we must first understand the fundamental forces of nature and the building blocks of matter. Nature contains gravity, the weak force, the electromagnetic force, and the strong force. The Standard Model, currently used by the scientific community, analyzes the building blocks of matter by considering the origins of these forces. The Standard Model posits that dividing matter further yields atoms, which are composed of protons, neutrons, and electrons. Dividing these further reveals a total of 17 fundamental particles: six heavy quarks, six light leptons, four force-carrying particles, and the Higgs boson. This Standard Model has been established as the most reliable theoretical framework through extensive experimental verification, and current scientific understanding is based on it. Among these particles, the Higgs boson is the one responsible for imparting mass to the other 16 components.
The Discovery Process of the Higgs Particle
The 16 particles, excluding the Higgs particle, had already been discovered through experiments. Therefore, scientists from various countries conducted experiments using particle accelerators to discover the final particle, the Higgs particle. A particle accelerator is a machine capable of accelerating objects to extremely high speeds. Using this machine, two objects were accelerated to extremely high speeds, collided, and the resulting particles were analyzed, leading to the discovery of the Higgs boson. Although particles thought to be the Higgs boson had been detected before October 4th, there was no certainty. This time, it was proven with over 99.99% probability that it was indeed the Higgs boson, making the discovery official.
The Value of the Higgs Boson Discovery
As mentioned above, the current scientific community is based on the Standard Model. While using the Standard Model, no situations deviating from it had arisen, so it was thought to be correct, but there was no evidence to prove its accuracy. Then the Higgs boson was discovered, providing evidence that the Standard Model is accurate. Consequently, the scientific achievements to date have gained validity. Stephen Hawking even remarked, “If the Higgs boson hadn’t been discovered, the scientific community would have been happier.” This is because if the Higgs particle had not been discovered, the Standard Model would not have gained certainty. If the Standard Model were incorrect, it could have led to a reversal of all previous scientific content—essentially, the scientific community could have been turned upside down. Thus, the discovery of the Higgs particle conferred validity upon the scientific community’s existing work and marked a significant milestone, drawing a line in the sand for science.
Mass Assignment by the Higgs Particle
As mentioned above, the Higgs particle possesses the property of assigning mass to matter. In reality, it is not the Higgs itself that assigns mass to matter; rather, the Higgs particle emerges during the process of mass assignment via the Higgs mechanism. The Higgs mechanism is a highly complex concept, which can be explained using an analogy involving magnets. Magnets possess polarity, which arises because the electrons within the atoms of the magnet align in a specific direction. This polarity causes objects to stick to the magnet, and force is required to separate them. This force can be viewed as mass. In other words, when one particle possesses a specific directionality, it attracts surrounding particles, and in this process, mass and the Higgs particle emerge. Therefore, discovering the Higgs particle allows us to glimpse how matter acquires mass.
The God Particle?
The Higgs particle is often called the “God particle.” This term reflects the scientific community’s philosophy regarding existence. The scientific community considers that which possesses mass to exist. Therefore, the Higgs boson, which endows matter with mass, creates the existence of matter. This entity that creates, or generates, matter corresponds to God, leading to the Higgs being called the “God particle.” These aspects have sometimes caused the discovery of the Higgs boson to clash with religion.
The Higgs Boson and the Origin of the Universe
The discovery of the Higgs particle also significantly impacted our understanding of the origin of the universe. Immediately after the Big Bang, the early universe was extremely hot and dense, and all particles existed without mass. As time passed, the universe expanded and cooled, allowing the Higgs field to form. Through this field, particles acquired mass. This process played a crucial role in determining the structure and properties of the universe. Therefore, the discovery of the Higgs boson extends beyond a mere physics achievement; it provides crucial clues for explaining the origins of the universe and our very existence.
Conclusion
We have now explored the Higgs boson. Discovered on October 4, 2013, using a particle accelerator, it plays the role of imparting mass within the Standard Model, which currently describes the scientific world. As the last particle predicted by the Standard Model to be discovered, its confirmation proved the model itself and validated the discoveries of the scientific community to date. Due to its role in giving mass to matter, it has also been dubbed the “God particle.” We hope that understanding the discovery of the Higgs boson, which has made such a significant mark on science, will help you grasp the scientific world more familiarly.
