I am learning about blackbody radiation. I am confused about two different statements from two different sources:
Source 1 says that
"All atoms/molecules above room temperature are accelerating at different rates. Accelerating charges emit e-m radiation and hence all objects above room temperature are continuously emitting (and absorbing) e-m radiation of a whole range of different wavelengths, a continuous spectrum."
Source 2 says that
"If the body is at a temperature above $0$K, as it must be, then its atoms and molecules have some energy. For a solid, this means the atoms and molecules are vibrating back and forth. Since this implies they are accelerating back and forth, and accelerating charges emit electromagnetic radiation, it follows that all objects are always emitting."
To summarise, source 1 says all objects above room temperature emit EMR, while source 2 says that all objects above $0$K emit EMR. Which is correct?
