At its finest scale, we should be able to probe down the "Planck length" which measures 10-35 meters. But the GEO600 experiment detected noise at scales of less than 10-15 meters.

要验证这一点，我们需要深入到普朗克尺度(10 - 35米)进行探测，而GEO600实验中探测到的噪音尺度为不到10 - 15米。

Currently, only one spacecraft inhabits L2: the US space agency's WMAP probe (which is making observations on which Planck hopes to build).

The energy that would be needed to probe the granularity of space is known as the Planck energy.

Details of these predicted variations have been confirmed by the Wilkinson Microwave Anisotropy Probe (WMAP) and other experiments, and will be further tested by the Planck satellite, data from which is currently under analysis.
