It is good asking the question what causes quantum fluctuations. Quantum fluctuations are caused by the initial singularity. The initial singularity fluctuates itself so not to be by itself. The purpose of the initial singularity is companionship. Companionship being a synonym for friendship and love. But in most simple terms; the purpose of the singularity is love.
