The key of Quasars into the dark matter explains why is so poor in galaxies and also are so diffuse. ISSUES HIGH, THE PHILOSOPHY, OF COSMOLOGY, anyway we’ve never seen dark matter directly. We only believe dark matter exists because we can see how it affects “regular,” or baryonic, matter, an overarching name for subatomic particles such as protons, neutrons, and electrons. Scientists only speculate what dark matter is made of, which contains an odd number of valence quarks (at least 3) are the most obvious candidate for dark matter, as baryonic dark matter is observed in the form of planets, low luminosity stars, and diffuse gas clouds, by definition, baryonic matter should only include matter composed of baryons. Anyway, it should include protons, neutrons, and all the objects composed of them, but exclude as a study, electrons and neutrinos which are actually leptons. Our understanding of the formation and evolution of galaxies has improved significantly during the pa

Historic scandal of Indian removal, day to remember. 1825 Jan. 27; US Congress approves Indian Territory (present-day Oklahoma), clearing the way for the forced relocation of the eastern Indian tribes.

In 1368 rebel armies—led by Zhu Yuanzhang (1328–1398)—overthrew the Yuan, and Zhu established a dynasty he named Da Ming (“Great Brightness”). The only emperor in China’s long history to have been born to a peasant family, Míng Dynasty that ruled China for nearly three hundred years. Born to a family of poor peasant farmers and orphaned at the age of 14, Zhu eventually became leader of a rebel army, and began to make plans for the overthrow of the Mongol (Yuan) dynasty. In 1363, Zhu defeated his rival Ch'en Yu-liang in the Battle of Lake Poyang (鄱陽湖之戰), one of the largest naval battles in world history. Zhu and the rebel forces advanced on Peking, forced the flight of the Mongol emperor, and proclaimed the Ming Dynasty in 1368. The reign of the Hongwu Emperor is notable for his unprecedented political ref
