| Supermassive Black Holes - 超大质量黑洞 - 14 | ||||||||
| It means that Silk and Rees theory may be right and if it is also right that supermassive black holes helped trigger star formation, then it must mean that all giant black holes and their galaxies are connected from birth. | |||||||||
| Supermassive Black Holes - 超大质量黑洞 - 13 | ||||||||
| Silk realized that the energy from this newly formed quasar would create intense temperature changes in the surrounding gas. This would cause the gas around the black hole and its newly formed quasar to condense into stars, which means, in effect, th | |||||||||

| This correlation is the most important thing weve learned about supermassive black hole so far. Astronomers are always looking for correlations. Whenever you find one thats really tight like this one, its a sign that there is some basic physics there | |||||||||
