红移意味着类星体是非常非常遥远的天体,比我们观测到的最遥远的星体还要远。
The redshift means that the quasars are very far away, more distant than the most distant galaxies we can see .
他们发现的红移量,似乎是由引力所引起,其数量恰好与广义相对论的预测相符合。
The amount of redshift they found that appeared to be caused by gravity agreed exactly with the predictions of general relativity.
最近达到了红移为2的观测与过去一百亿年中暗能量一直大约在目前状态下相一致。
The latest observations, which reach a redshift of about 2, are consistent with dark energy having been around in more or less its current form for the past 10 billion years.
最遥远的爆炸光飞向地球时,被宇宙的膨胀拉长而呈红色——一种被称作红移的现象。
As light from the most distant explosions travels toward Earth, it is stretched by the universe's expansion so that it appears red, a phenomenon known as redshift.
结合对早期爆炸留下的红移现象的研究,推知宇宙诞生于约137亿年前,误差2亿年。
Combined with studies of the radiation left over from that primordial explosion, they have found that the universe was born 13.7bn years ago, give or take 200m years.
此外,由于宇宙膨胀,物体(比如恒星或星系)离开地球的速度,通过红移可以被算出来。
In addition, the speed at which an object such as a star or galaxy is moving away from Earth, because of the expansion of the universe, can be worked out from its red-shift.
广义相对论预言这种光的波长会因这些星系的质量而有少量的偏移,这种效应称为引力红移。
General relativity predicts that the wavelength of this light will be shifted by a small amount due to the galaxies' mass, in an effect called gravitational redshift.
类星体一种类似星体的物体,它有很大的红移并放射出大量的蓝光,而且经常还有无线电波。

GRB with redshift 6.3 has been detected recently, which indicates that GRBs now begin to serve as probes of the high-redshift cosmology.
利用哈勃空间望远镜可能会找到一些红移值达到10的星系,但这些天体应该很罕见并且极其微弱。
With the Hubble Space Telescope it might be possible to find some galaxies up to redshift 10, but these objects are expected to be very rare and extremely faint.
