The key development lies in the ability of the sphere, an optical device, not only to remain invisible itself but to slow light.

关键在于光纤球功能的开发，一种光学设备，不仅要保持自身的不可见性，还要能减缓光线。

The sphere, for instance, represents how space is bent around a star or other mass - light passing through this warped space bends in an effect called gravitational lensing.

作为例子，这个球面代表了恒星或其他质量附近的空间是怎样弯曲的-光通过这个扭曲空间所引起的弯曲称为引力透镜效应。

However, since the laser, being light, acts as a wave, the theory is that the sphere should end up in two places at once as a result.
