What causes black body radiation? I don't think it's the electrons being exited and falling back because the result of that would be the emission spectrum of the element...

Black body radiation is the electromagnetic radiation emitted by an object that absorbs all incoming radiation and reflects none. It is a type of thermal radiation, meaning it is caused by the heat of the object.
Black body radiation is caused by the thermal energy of an object. When an object is heated, its atoms and molecules vibrate and produce electromagnetic radiation. The frequency and intensity of this radiation depend on the temperature and surface properties of the object.
The color of an object does not affect its black body radiation. The frequency and intensity of the radiation are solely determined by the temperature and surface properties of the object. However, the color of an object can affect how much radiation it absorbs and reflects, which can impact its temperature and therefore its black body radiation.
It is called "black" body radiation because an ideal black body is an object that absorbs all incoming radiation and reflects none. This means that the object would appear completely black to an outside observer. In reality, there are no perfect black bodies, but many objects can come close to exhibiting black body radiation, such as stars and planets.
Yes, black body radiation can be controlled and harnessed to some extent. For example, in photography and thermal imaging, black bodies are used as reference objects to calibrate the measurements. In addition, black body radiation is also used in various industrial and scientific applications, such as in the creation of infrared lamps and in the study of the properties of materials at high temperatures.
