The Separation of Fundamental Forces in the Early Universe

As per the standard model of cosmology, the fundamental forces as we know them today were not always distinct. Early in the universe, just after the Big Bang, these forces were unified into a single force.
As the Universe cooled and expanded, these forces began to separate. This process is referred to as symmetry breaking.
The Strong Nuclear Force was the first to separate. This happened at an energy level of approximately 10¹⁵ GeV (Giga electron volts), a fraction of a second after the Big Bang.
The Strong Nuclear Force is responsible for holding the atomic nucleus together. It is the strongest of the four fundamental forces, but it has a very short range.
The separation of the Strong Nuclear Force marked a significant event in the early universe, leading to the conditions that would eventually allow for the formation of atoms.
The next force to separate was the Electroweak Force, splitting into the Electromagnetic Force and the Weak Nuclear Force. This happened at an energy level of approximately 100 GeV.
The Gravitational Force, although considered a fundamental force, doesn't fit neatly into this sequence as its unification with the other forces has not been conclusively established.
Scientists continue to study these early moments of the universe, and the separation of these forces, to better understand the fundamental workings of our universe.
