New results from the Hubble Telescope, released in April 2019, have deepened the puzzle of the expanding universe.
但经过了几十上百亿年的膨胀,不断增长的暗能量开始让宇宙膨胀缓慢加速。
But eventually, after numerous billion years of expansion, the growing abundance of dark energy caused the expansion of the universe to slowly begin to accelerate.
广义相对论为各类的发现奠定了基础,如大爆炸、宇宙膨胀和黑洞等。
General Relativity laid the foundation for all kinds of discoveries, such as the Big Bang, the expansion of the universe and black holes.
在成为科学传播者之前,我花费了15年时间研究星系演化、暗物质性质,以及宇宙膨胀。
Before becoming a science communicator, I worked for 15 years researching the evolution of galaxies, the properties of dark matter, and the expansion of the universe.
而这种暗能量与“正常”物质施加的引力相反,导致宇宙膨胀加速。
And this Dark Energy exerts a force opposite to the attractive force exerted by“normal” matter, causing the expansion of the universe to accelerate.
The High-Z Supernova Search Team was an international cosmology collaboration which used Type Ia supernovae to chart the expansion of the universe.
普朗克的数据表明,确认宇宙膨胀理论的光模式实际上是由太空尘埃引起的。
The Planck data suggests that light patterns that confirmed the cosmic inflation theory were actually caused by space dust.
据研究人员说,其中一个说宇宙膨胀速度比另一个快了近10%。
One says the universe is expanding almost 10 percent faster than the other.
如果宇宙膨胀的速度是光速,那么宇宙的半径就应该是137亿光年左右。
Even if the space expanded at the speed of light, the radius of the universe should have been about 27.4 billion light years.
如果宇宙膨胀速度比预想更快,那就意味着它能更快地达到目前的大小,因此应该相对年轻一些。
If the universe is expanding faster, that means it got to its current size more quickly and therefore must be relatively younger.
梅尔基奥里说,宇宙膨胀的传统模型暗示宇宙应该是平坦的。
The conventional model of the universe's inflation, Melchiorri said, suggests that the universe should be flat.
毕竟它们是科学家--宇宙膨胀率的计算会根据我们测量它们的方式而不断改变不同的数值。
They're scientists after all- calculations of the rate of expansion of the universe keep turning different values depending on how we measure them.
年,两个独立的天文学家小组发现宇宙膨胀的加速与均匀分布的暗能量的存在是一致的。
In 1998, two independent teams of astronomers discovered that the universe's expansion was faster, consistent with the existence of a uniform contribution from Dark Energy.
他们在1998年推断,宇宙膨胀正在加速,而非如同预期的减速,让人们对天体物理学的传统思想改观。
In 1998 their conclusion that the Universe's expansion was speeding up, rather than decelerating as expected, took a hammer to conventional thinking in astrophysics.
如果宇宙膨胀得比预期的快,这意味着它可以更快地达到当前的大小,所以它应该相对年轻。
If the universe is expanding faster than previously thought, that means it got to its current size quicker and therefore must be younger.
但当提及宇宙膨胀的速度有多快速这个问题时,一些新的宇宙学的测量结果却是让我们倍感困惑。
But when it comes to the question of how fast our Universe is expanding, some new cosmological measurements are making us ever more confused.
他们都试图确定哈勃常数,这是一个描述特定时刻宇宙膨胀率的参数。
They both sought to determine the Hubble constant, a parameter that describes the rate of expansion of the universe at a given moment.
报道称,还有超过50万人试图下载这篇题为《宇宙膨胀的属性》的论文。
More than 500,000 people have also tried to download the paper, titled“Properties of expanding universes”.
与此同时,哈勃和美国天文学家MiltonHumason在ApJ上发表了关于宇宙膨胀的新结果。
In the meantime, Hubble and the American astronomer Milton Humason published new results on the expansion of the universe in the Astrophysical Journal.
