Edwin Hubble, whose discovery ___ the expansion of the universe, was an important astronomer. A. proved B. proves C. has proved D. had proved 相关知识点: 试题来源: 解析 A。解析:Edwin Hubble的发现证明了宇宙的膨胀,这是过去发生的事情,所以用一般过去时,prove的过去式是proved。反馈 收藏...
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。

The expansion wouldn’t be able to accelerate anymore, 此时扩张无法再加速了, but the universe would keep getting bigger. 但宇宙会持续变得更大。 Clusters of galaxies would separate. 一群一群的银河会分离开来。 The objects within the galaxies– 在银河中的物体—— suns, planets, and solar systems...
A finite lifetime of the Universe is transformed to an infinite lifetime for these observers including elementary particles.Paul Smeulders现代物理(英文)Smeulders, P., 2013, `Why the expansion of the universe appears to accelerate', Journal of Modern Physics 4(6), 780-783, viewed 12 February ...
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. ...
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 matter to be released and spr...
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 ...
If the expansion of the universe continues to accelerate, 如果宇宙的扩张继续加速, it will eventually overcome not only the gravitational force – tearing apart galaxies and solar systems– 这个拉力最终不仅会克服重力影响——导致银河系和太阳系分离—— ...
