The invisible field that gives our entire universe its weight
In short: Without a specific subatomic interaction, electrons would lack mass and atoms could never form. This means you, the earth, and every star in the sky would cease to exist as we know them. It all comes down to an elusive particle known as the Higgs boson.
In 1964, physicists Peter Higgs and François Englert proposed a groundbreaking solution to a fundamental mystery: why do some particles possess mass while others, like photons, do not? They theorized the existence of the Higgs field, an invisible energy field that permeates the entire universe. Mass is gained by particles through engagement with this field, where greater interaction levels result in increased weight.
The Higgs boson is the quantum manifestation or excitation of this field. To visualize it, imagine a room full of people representing the Higgs field. If a person (a particle) enters and starts to dance, others move in response—this movement is what grants the particle its mass. Because it acts as a force carrier, the Higgs boson is unique; it is the only elementary particle with zero spin, making it a quantum mechanical equivalent to having no angular momentum.
Despite being a theory for decades, the work was so significant that Higgs and Englert were awarded the Nobel Prize in Physics in 2013. The hunt for physical proof led to the construction of the Large Hadron Collider (LHC) at CERN, the world's most powerful particle accelerator. On July 4, 2012, researchers finally confirmed the boson's existence, a discovery that completed the Standard Model—the primary scientific description of the subatomic world.
The Higgs boson is remarkably heavy for an elementary particle, with a mass of approximately 125 billion electron volts. This makes it roughly 130 times more massive than a proton. By confirming the Higgs field, scientists proved that mass is not an inherent property of matter but rather a result of constant interaction with the fabric of space itself.
