Despite the universe’s apparent stability, having existed for 13.7 billion years, several experiments hint at a precarious state, teetering on the precipice of a catastrophic event. This instability is attributed to the Higgs boson, a fundamental particle crucial to our understanding of mass and interactions in the universe. The Higgs boson interacts with a field, known as the Higgs field, responsible for the masses of all particles. This field pervades the universe uniformly, ensuring consistent observations of particle interactions across vast distances. However, the Higgs field might not be in its lowest possible energy state. This implies a potential for a dramatic change in the laws of physics, as the field transitions to a lower energy state, similar to water transforming into vapor. Such a phase transition would create bubbles of space with drastically different physics, altering fundamental properties like electron mass and interactions. While measurements from the Large Hadron Collider suggest this event could occur in a few thousand billion billion years, it’s crucial to remember that the universe is considered meta-stable, with the world’s end not imminent. Quantum fluctuations in the Higgs field could trigger bubble formation, but these events are incredibly rare. However, strong gravitational fields or hot plasma can enhance the likelihood of bubble formation by providing energy. This raises a critical question in cosmology: could the extreme conditions shortly after the Big Bang have triggered such bubbling? Interestingly, the early universe’s high temperature stabilized the Higgs, preventing a catastrophic phase transition. Our research explored a specific source of heat, primordial black holes, which could constantly induce Higgs bubbling without the stabilizing effects of the early universe. These black holes, formed from the collapse of dense spacetime regions, can be incredibly small, even as light as a gram. Unlike stellar black holes, they evaporate over time due to quantum mechanics, emitting Hawking radiation. This evaporation process makes them behave like impurities in a fizzy drink, accelerating bubble formation. However, the absence of such a catastrophic event implies that primordial black holes are unlikely to have existed. This finding effectively eliminates cosmological scenarios that predict their existence, unless evidence of their past existence is found in ancient radiation or gravitational waves. Such a discovery would suggest a deeper mystery surrounding the Higgs boson, implying the existence of unknown particles or forces that protect it from bubbling in the presence of evaporating primordial black holes. Ultimately, this exploration reveals our ongoing journey of discovery about the universe, from its smallest components to its grandest structures.
