- But then we need to explain why Omega started out very close to 1 in the early universe. 但是另一方面我们需要解释为什么欧米加在早期宇宙中开始非常接近1。
- Similarly, the densest regions of the early universe are the smallest protogalaxies. 同样的,早期宇宙密度最高的区域是最小的原星系。
- This transition took place some 10~(-5)s after the Big Bang in the early universe in an inverse direction. 这一过程与大爆炸理论预言的宇宙在最初的10~(-5)s内发生的相变过程相同,但方向相反。
- Such terms would be negligible in the early universe but would speed expansion later on. 这些项在宇宙早期可以被忽略,而在后来则可以用来加速膨胀。
- Adams agrees."It could be there's some event that happened in the early universe that's [undetectable]," says Adams. 亚当斯同意克劳斯的观点,说:“事情可能会是这样的:早期宇宙中发生过某个情况,只是不可探知罢了。
- The role of collisions in clusters may help scientists understand the evolution of galaxies in the early universe. 星系团里的碰撞事件所扮演的角色,或可帮助科学家了解星系在早期宇宙中的演化。
- Helium produced in the early universe, for example, makes up about 24 percent of the total matter. 例如,在早期宇宙所产生的氦,约佔了所有物质的24%25。
- Such a device would look back at the early universe to the time when large-scale structures such as galaxies and stars formed. 通过这种望远镜,人们可以回顾宇宙的早期形成时期直到大规模天体结构如星云和恒星形成的时期。
- Such waves would be coming from the early universe, which we don't know much about, so we can't predict the amplitudes well. 这些波来自我们尚不太了解的早期宇宙,因此还不能很好的预测其振幅。
- Thus, we can conceive of the early universe as a pile of overlapping grapefruits that stretches infinitely in all directions. 因此,我们可以把早期宇宙想成是水果摊上一堆往各个方向无穷延伸的葡萄柚。
- The simulation reveals how pre-stellar gases would have actually evolved under the simpler physics of the early universe to form this protostar. 模拟揭示了宇宙中分布的气体,如何在早期宇宙中相对简单的物理机制的作用下形成这种原恒星。
- China's earliest university----Tianjin University. 中国最早的一所大学天津大学
- We will have a better understanding of how matter behaves at the unfathomably high temperatures and pressures of the early universe. 同时,我们将进一步了解物质在宇宙初期不可思议的高温高压下,是如何表现的。
- And by comparing the heights of the two peaks, cosmologists can gauge the relative strengths of gravity and radiation pressure in the early universe. 并且,从两峰之间高度的比较,宇宙学家得以测度早期宇宙中重力与辐射压力的相对强度。
- The early universe, even if it is only a centimeter across, has exactly the same number of microstates as the entire observable universe does today. 早期宇宙即便仅有一公分大小,它所包含的微观态应等于今日可观测宇宙所拥有的微观态数目。
- The wealth of data from these experiments is already forcing theorists to reconsider some cherished ideas about matter in the early universe. 以往,大部份的计算都将自由的夸克与胶子当成理想气体而非液体来处理。
- The wave that causes the region to reach maximum negative displacement exactly at recombination is the fundamental wave of the early universe. 能使该区域于再复合时达到最大负位移的波,就是早期宇宙的基频声波。
- We started early in order to arrive before dark. 为了在天黑前到达,我们很早就动身了。
- When the hot plasma of the early universe emitted the radiation we now see, it was receding from our location at about 50 times the speed of light. 当早期宇宙的热电浆发出我们现在所看到的辐射时,它正以大约50倍光速远离我们的这个位置。
- All previous ideas of galaxy formation had assumed that gas in the early Universe simply condensed to form stars and galaxies. 所有先前的星系形成观点都假设:在早期的宇宙中气体凝结形成了行星和星系。
