Why is the speed of light absolute?

Click For Summary
The discussion centers on the concept of the speed of light being absolute in the context of special relativity, contrasting it with the non-absolute nature of other speeds. Participants express a desire for a deeper philosophical or physical explanation for why light's speed is universally constant, as opposed to merely accepting it as a postulate based on empirical evidence. The conversation touches on the implications of Lorentz invariance and the nature of spacetime, suggesting that the speed of light may be a fundamental property rather than a derived one. There is also a consideration of how mass affects the speed of objects, with a focus on the unique behavior of massless particles like photons. Ultimately, the quest for a satisfying explanation of the absolute nature of light's speed continues, highlighting the complexity of reconciling intuitive understanding with established scientific principles.
