The 5th state of matter
Beautiful filament-systems are often shown by the astonishing development of the modern astronomy. Most of these filaments have an exact circular cross section. Filaments have the same interesting characteristics from a diameter of 0.01 mm to that of many 1000 of light-years. Filaments are incorrectly seen to be of plasma, however, particles move in only one direction in them, often against gravity. In this non-thermal (fifth-) state of matter, particles have up to 1016 -times higher energy than those in the hottest stellar plasma. The corona-problem and hundreds of other problems of astrophysics are solved at once.
