Homework Statement
I am taking a course from the Teaching Company called the "Physics of History". Two statements by the teacher seem in conflict to me as an amateur.
1. The average temperature of the cosmos is about 3 degrees K.
2. Most of the material in the cosmos is in the form of plasma which is extremely hot.
I am pretty sure the answer might be difficult to explain to an amateur so a web reference would suffice, Thanks/
