Physicist James McCanney and Plasma Physicist Dr. John Brandenburg

I listened to Coast To Coast AM and heard an interview with physicist James McCanney, not Briane Greene.
He talked about Comet Elenin.
I also heard an interview with plasma physicist Dr. John Brandenburg, not Brian Greene.
He talked about Einstein's theories.
He talked about his own theory that connects electromagnetism and gravity.
I enjoyed both interviews.
