Light from a source can be seen from a distance due to its ability to travel through space without significant absorption, while heat, primarily experienced as infrared radiation, dissipates more quickly and requires proximity to be felt. Infrared radiation is commonly associated with heat because it is emitted by warm objects and is the primary type of radiation we detect as warmth. Although distant stars emit heat, it is not felt without sensitive instruments, as the intensity diminishes over vast distances. The discussion highlights the differences in how light and heat propagate and are perceived. Understanding these principles clarifies why we can see light from afar but need to be closer to feel heat.
