- I wish to gain a physical intuitive understanding as to why the scalar massless wave equation is conformally invariant.

It can be shown mathematically that the scalar massless wave equation is conformally invariant. However, doing so is rather tedious and muted in terms of physical understanding. As such, is there a physically intuitive explanation as to why the scalar massless wave equation is conformally invariant?
