Abstract
Listening to echoes has long been a way to estimate distances, a technique
whose backbone is the time delay. The gravitational field also creates a
time delay, called Shapiro time delay, that helps us extract some
information from the field and is indeed due to the photon journey through
the field. Here, the ability of the Shapiro effect to distinguish naked
singularities from non-naked ones (black holes) is discussed. It is also
inferred that this time delay may be hired to compare the various types of
singularities with different dimensions. Besides them, the possibility of
detecting the rotation of the assumed objects through surveying the
gravitational time delay is also addressed.
