In the study of the universe, the expansion of the universe means that: A. The space between galaxies remains the same over time B. Galaxies are moving closer to each other, reducing the space between them C. The space between galaxies is constantly increasing D. Galaxies are disappearing, ...
解析 B。解析:宇宙膨胀(the expansion of the universe)意味着星系之间的距离在增加(the distance between galaxies is increasing)。选项A说宇宙变小是错误的;宇宙膨胀时恒星之间距离是增大而不是靠近,选项C错误;行星也不是朝着太阳移动来体现宇宙膨胀的,选项D错误。

But it wasn't! I have no idea what you mean. "The expansion of the universe" is standardly defined, in cosmology, to mean "the expansion of the congruence...
Cosmic expansion just means that the distance between galaxies is growing with time. Even an infinite space can become bigger. Welcome to the paradoxes of infinity. Infinity gets much weirder though. As you travel with your sp...
The present rate of the expansion of our Universe, the Hubble constant, can be predicted from the cosmological model using measurements of the early Universe, or more directly measured from the late Universe. But as these measurements improved, a surprising disagreement between the two appeared. ...
Why is the Universe Expanding? Scientists believe that the expansion of the universe began with the Big Bang and is still expanding now. They postulate that the Big Bang occurred due to a large amount of energy being packed into a small point in space. When the explosion occurred, it caused...
THE expansion of the universe expected by theory has been strikingly confirmed by radial velocity observations of the spiral nebulae, which, we may remark, is discussed by Dr. R. O. Redman elsewhere in this issue (p. 836), but a serious difficulty immediately arises. The expansion is so ...
