During an earlier epoch the universe was filled with hot dense plasma. During this time the dominant structure forming force was electromagnetic. As plasma is prone to self organizing the remnant of this epoch can be seen in the largest scale structures in the universe namely filaments. As the universe cools and condenses however large plasma currents degenerate and gravity becomes the dominant force. There is also room for other fundamental forces to have dominated in even earlier epochs.
Certain cosmic objects appears to have needed more time to form than the age of the universe if gravity alone is the structure forming force.
Is there an astrophysical theory that holds that different fundamental forces dominated structure formation at different stages in the evolution of the universe?
