According to the prevailing scientific understanding, the Big Bang theory suggests that the universe originated from a singularity—an extremely hot and dense state. However, it is not accurate to say that everything in the universe is created from a single fundamental particle.
During the early stages of the Big Bang, the universe underwent a rapid expansion known as cosmic inflation. Subsequently, elementary particles, such as quarks and leptons, formed in the hot and energetic environment. These particles combined to form protons, neutrons, and electrons, which later combined to form atoms.
As the universe continued to evolve and cool down, gravity played a crucial role in the formation of structures like galaxies, stars, and planets. In this process, various interactions and forces, such as the electromagnetic force and the strong and weak nuclear forces, came into play.
So, rather than everything in the universe being created from a single fundamental particle, it is more accurate to say that the universe emerged from a highly dense and energetic state and underwent a complex sequence of events that led to the formation of a wide array of particles, elements, and structures we observe today.
It's important to note that our understanding of the early universe and the processes involved is continuously evolving as scientific research progresses. The Big Bang theory provides a framework to explain the origin and evolution of the universe, but the details of particle physics and cosmology are still subjects of ongoing research and investigation.
