It has been shown that above 100 GeV in energy, intermediate vector bosons behave like photons. What is the significance of this in the early universe?
A)Light (the cosmic microwave background radiation) was emitted by the weak interaction.
B)Above this energy matter behaved like radiation: the radiation-dominated era of the early universe.
C)The weak and electromagnetic interactions were unified.
D)The strong force separated from the electromagnetic force.

Question

Quizplus · Accepted Answer

The unification of weak and electromagnetic interactions is known as electroweak force, which is significant in the early universe as it played a crucial role in the formation and evolution of the universe. At high enough energies, the intermediate vector bosons of the weak force behave like the photon of the electromagnetic force, indicating the unification of the two forces. This unification could have occurred during the early universe when the temperature and energy were high enough for the electroweak force to be dominant.
