He has claimed that by slowing down light by way of an optical illusion, the light can then be bent around an object to 'conceal' it.
他称，通过一种光幻觉可以使光线变得迟缓，从而光线可以弯绕着物体而达到“隐形”效果。
The spray of light scattered forward by these fields could push the object backward, against the movement of the beam itself.
光穿过这些场产生衍射，发散如喷雾状的衍射光向前方传播，因此对物体产生了一个与光束传播方向相反的推动。

Redshift refers to what happens when light seen coming from an object is proportionally shifted to appear more red.
红移是指当一个天体发出的光线看起来成比例地更偏向红色。
Researchers have known for a long time that blasting an object with light can push the object away.

As for the Comet Hopper, if it gets the green light, it will be visiting an object that's like a time capsule from the earliest days of the solar system.
至于彗星跳跃者，如果它拿到了许可，将会造访一个类似时间囊、形成于太阳系系统早期的物体。
To accelerate an object to the speed of light, you'd need nothing short of an infinite amount of energy.
为了把一个物体加速到光速，你需要的简直是无限的能源。
This oddly shaped object is Saturn's moon Calypso, brought to light in a new high-resolution picture released March 26, 2010.
实际上，照片上这一形态怪异的物体是土星的卫星卡里普索。
And if there are multiple light sources, why does each object only cast one shadow?
而且如果说有多个光源的话，为什么每个物体只有一个影子呢？
Even invisibility now looks almost possible using a new type of material that can direct light to flow around an object as though it were not there.
甚至隐形现在也几乎成为可能：一种新型材料可以引导光线在物体四周流动，使得物体看起来就像不存在一样。
When light passes near a massive object, its path gets bent, like a car driving on a curved, banked road.
当光线接近一个巨大物体时，光的路径会变弯，就像汽车在弯曲的车库道上行驶一样。
However, if you shine a laser at the surface of an object, the way the light is reflected back can be used to gather information about the same features.
然而，如果采用激光对物体表面进行照射，那么光线反射回来的方式能用来收集具有相同特征物体的信息。
But others object not to the price but to the quality of the light, which has a different spectrum from the one they are used to.
也有人不是对价格高而是对此灯发出的光的质地持异议，因为其光谱与人们已习惯的不同。
Cloaking used special materials to deflect radar or light or other waves around an object, like water flowing around a smooth rock in a stream.
做这件斗篷的材料很特殊，能使包括雷达或光波在内的各种波遇到物体后发生偏转，就象溪流遇到光滑的石头那样。
When light bounces off of an object, it does so at an infinite number of angles.
光线从某一物体上折射时，会沿着无数不同的角度散开。
The direction of light reflected from an object depends on its alignment.
光线的方向会根据对象的位置发生反射。
