像这样的伪时间和旅行每天都在发生并被我们人类的探测工具(仅举几个例子,如哈勃空间望远镜、设置在夏威夷的一部庞大的凯克望远镜和钱德拉X射线观测卫星)拍摄下来。
Pseudo-time travel like this happens every day, with pictures taken by the Hubble Space Telescope, the mammoth Keck telescopes in Hawaii and the Chandra X-ray Observatory satellite to name just a few.
宇宙里资格最老的居民被称作UDFy-38135539,不过科学家怀疑他作为纪录保持者的头衔——之前是被一个伽马射线暴持有的——不会持续很长时间。
The universe's most senior citizen is called UDFy-38135539, but scientists suspect its title as record-holder -- previously held by a gamma-ray burst -- will not last.
由于按照这一构想,该公司为控制X射线强度而开发的技术将要作出调整,以适应控制质子射线强度的需要,因此该公司还需要再过一段时间才能决定这是否可行,而一旦能下定决心,癌症放射治疗的创伤性就将大大减弱,而疗效则会大大增强。
It will take a while to determine whether this will work. But if it does, radiation therapy for cancer could become a lot less traumatic and a lot more effective.
