Abstract
Electromagnetic waves propagated in cosmic space derive from a variety of mechanisms. The major contribution in the optical region of the spectrum is from radiation resulting from bound-bound electron transitions between discrete atomic or molecular states, free-bound transitions during recombination, and free-free transitions in the continuum. In the latter case, when for transitions between levels, radiation classified as bremsstrahlung results from the acceleration of electrons traveling in the vicinity of the atom or ion.

Notes
- 1.
The “island universes” concept was introduced by the philosopher Kant (1724–1804).
- 2.
A time frame study of the fields shows that the strength of the “static” component does vary slowly in time.
- 3.
The function δ 2(y) is to be interpreted as δ(y)T∕2π where T is the period of revolution.
- 4.
While P ω (0) has no rotation, P ω (1) does rotate.
- 5.
Long after the thermal plasma X ray burst, streak photographs show the Bennett-pinched exploded wire plasmas converging onto the centrally confined plasma because of the Biot-Savart attraction. The pinhole camera placed in front of the anode records a single “dot” of X rays.
