Click For Summary
The discussion revolves around the complex nature of light, particularly its dimensionality and mass properties. Participants debate whether light is two-dimensional or zero-dimensional, with some asserting that it cannot be seen in three dimensions unless reflected. The conversation touches on light's lack of rest mass while acknowledging its energy-related mass, leading to confusion over definitions of mass in physics. There is a consensus that the understanding of light remains controversial, with many theories and definitions existing without a clear resolution. The dialogue highlights the ongoing struggle to reconcile these scientific concepts, suggesting a need for clearer definitions and understanding.

Don't mention it, Pete. Thank's for discussion.
You're welcome.

Just one last note. There are many people who claim that mass, m, always means 'rest mass' and that is what the entire physics community means when they use this term. I've composed a list of counter examples to dispel this myth. See
