Blackbody radiation explained

A major problem facing scientists in the s was to explain blackbody radiation. Like a metal, it will conduct an electric current, but nowhere near as efficiently. It was Kirchhoff who took first two steps in this direction. Some, like glass, seem to absorb light hardly at all—the light goes right through. At even higher temperature, the objects actually glow, like the heating element of toaster or red-hot electric stove burner. So, any light undergoes multiple reflection inside the sphere, actually, cannot exit through the hole. Their results would tell us much about the thermal history of the Universe.
