    The article states that this matter is at “temperatures of around 1 million degrees Celsius”. This seems incredible, if true. Is my expectation of how temperature works in a near-vacuum simply flawed? Google seems to say the average temperature of space is around 2 Kelvin. How can 30% of ordinary matter be almost as hot as the sun, but apparently not affect the average?

    >>Ordinary matter, or "baryons," ...

    Whoa. Leptons are ordinary matter too. Electrons are leptons.
