If scientists find that the expansion of the universe has always been accelerating, they will have to completely revise their understanding of cosmic evolution
若科學家發現宇宙總是在加速膨脹，則他們必須修正其對宇宙演化的認知。 -
Another way to think of the problem is in terms of cosmic expansion
思考這個問題的另一個進路，就是宇宙膨脹。 -
Cosmic expansion has got its groove back : once thought to be winding down, it is actually speeding up
宇宙膨脹也因此重獲律動：當你認為它應該變慢時，實際上卻變快了。 -
Cosmic expansion continued to cool the gas, so one might expect that the cosmic gas would still be cold and neutral today
宇宙膨脹持續冷卻這些氣體，因此我們預期這團宇宙氣體在今日仍然應該保持著低溫與電中性的狀態。 -
Cosmic expansion had diluted the density of the gas to the point where collisions were too infrequent to equalize the spin and kinetic temperatures
宇宙膨脹至此，已將氣體稀釋到一定的程度，使得原子碰撞不再頻繁地讓自旋與動力溫度相等。 -
Like darwinian evolution, cosmic expansion provides the context within which simple structures form and develop over time into complex structures
宇宙的膨脹就像達爾文的演化論，對于簡單的結構如何逐步發展形成復雜的結構，提供了可循的脈絡。 -
You will probably die long before your alter egos come into view, but in principle, and if cosmic expansion cooperates, your descendants could observe them through a sufficiently powerful telescope
也許你早在見到另一個你的很久以前就死了，但是原則上，如果宇宙膨脹的方式肯配合，有一天你的後代子孫，應該可以用夠強的望遠鏡觀察到他們。 -
In recent years researchers have calculated that if a value called omega, the ratio between the average density of the universe and the density that would halt cosmic expansion had not been within about one quadrillionth of one percent ; does anyone know hot to write that number
聽著，最近從事研究的人計算到，若一個值稱為亞米加，宇宙平均密度與停止宇宙擴張的密度的比例，少於百分一的千萬億分一。誰知道這怎麼寫？
