MRI expert Pierre-Marie Robitaille on the design flaws of COBE, WMAP, & Planck and the violation Kirchhoff's Law:
Here are his talks:
Pierre-Marie Robitaille: The Cosmic Microwave Background
Pierre-Marie Robitaille: On the Validity of Kirchhoff's Law
Robitaille holds the world record for highest resolution MRI imaging.
An interesting point he makes is that cosmological sources would not vary over time, yet the COBE, WMAP, and Plank data are highly variable.
Here are his papers detailing the design flaws of COBE, WMAP, and Planck:
