The Basic Questions of Cosmologyogy. For instance, scientists want to know the average density of matter in the universe — that is, how much mass per volume exists if all planets, stars, gas clouds, and so on, were “ground up” and equally distributed in space.

At the end of 1995, Hubble’s discretionary time was used to observe one small area in the sky for 10 days.

The Search for Cosmic Numbers. is the Hubble constant, the measure for the rate at which the universe expands. The determination of this number is theoretically very simple. The redshift is plotted against the distance for a number of galaxies; this plot will show a linear relationship (the Hubble law), and the slope of that line gives the value for the Hubble constant.作者: Leaven 時間: 2025-3-25 18:28
Gravitational Lenses: Hubble’s Telephoto Lensnobody believed that such “minimal” effects could ever be observed in the universe. What would happen if the gravitational lens were caused not by a star but by a massive galaxy or even a cluster of galaxies? This should enhance the effect considerably.
