Scientific paper

It is proposed that the 2.7-K microwave background may be the result of absorption and reemission of light from galaxies by graphite whiskers ranging in length from 0.1 to 1.0 mm. The growth of whisker grains condensing in intergalactic space on suitable seed nuclei is analyzed, and it is noted that the excess of carbon over oxygen necessary for such condensation could be produced by explosions of supermassive carbon stars in dense galactic nuclei. The mass density of such grains required to produce the observed microwave background is estimated to be of the order of 10 to the -34th power gm/cu cm.
