Nearby Intergalactic Mattertively easy to see. Therefore, if we wish to estimate the density of the universe, only taking into account the galaxies, we may get a lower limit below the true figure. It is thus important to find out what contribution may be attributed to sources other than galaxies, and in particular to gas, dust and other intergalactic objects.作者: 吞下 時(shí)間: 2025-3-22 05:19 作者: impaction 時(shí)間: 2025-3-22 11:42 作者: 拖網(wǎng) 時(shí)間: 2025-3-22 15:07 作者: Mnemonics 時(shí)間: 2025-3-22 20:17
