Light emitted in this environment will have a certain frequency, which is related to the time scale (or the gravity strength) of the environment.

在那样环境下所发射的光会具有一定的频率，这个频率是与环境的时间标度(或引力强度)有关。

Disable any services that are not needed, and consider an appropriate execution frequency for your environment for the services you do use.

禁用所有不需要的服务，并为使用的服务设置适合自己环境的执行频率。

When that light travels to a new environment, say to a telescope on Earth, where there is comparatively lower gravity, and time moves more slowly, the light's frequency will decrease.

当光运行而到达一个新的环境时，譬如到达了地球上的某个望远镜，由于地球上只有较小的引力，时间的流逝就会变慢，由此光的频率就会降低。

High resolution is achieved by measuring motion rather than radio frequency signals as wifi does, and is based on where and how the person moves through an environment over time.
