An important distinction within quantum physics is that of discrete and continuous values. For example, much of the various spectra are composed of quantized energy shifts, creating ultimately discrete spectra. However, there does exist true continuous spectra. The example I want to focus on is that of the Sun's emissions. I understand that black body radiation plays an important role in the production of this continuous spectrum, but I want to know why. Can anyone help provide an in-depth explanation of this process, or link me to materials that do?
Greatest point of confusion: I struggle to understand the theory between what a blackbody actually is. The commonly used term of an idealized object provides no clarity.
