value: by averaging over many structures
type: OTHER
Source sentences:
text: Stuart Samuel also suggested that the experiment did not actually measure the speed of gravity because the effects were too small to have been measured.
text: This effect is not detectable for any one structure since the true shape is not known, but can be measured by averaging over many structures.
text: Even if the multiple images are too close to each other to be resolved, the effect can still be measured, e.g., as an overall brightening of the target object; a number of such "microlensing events" have been observed.
text: GB-B used four spherical gyroscopes and a telescope, housed in a satellite orbiting 642 km (400 mi) above the Earth, to measure in a new way, and with unprecedented accuracy, two extraordinary effects predicted by the general theory of relativity (the second effect having never before been directly measured):
text: Designing a physics experiment involves a basic choice: maximize the effect to be measured, or minimize the “noise” that obscures it.
