Rhondium sensor: Difference between revisions

A '''rhondium sensor''' was an ''ad hoc'' device built at least twice by [[the Doctor]]. As they were built from whatever materials were available at the time, the versions created by the [[Third Doctor|Third]] and [[Tenth Doctor]]s varied greatly in design. They were used to detect delta (or rhondium) particles. These particles indicated the presence of some kinds of space-time fissures.

In the case of the Third Doctor, the device alerted the Doctor to the use of the [[Sontaran]] [[Osmic projector]], itself a device that created a quantum tunnel that connected two disparate points in time. ([[DW]]: ''[[The Time Warrior]]'', [[MA]]: ''[[Lords of the Storm]]'') For the Tenth, the device detected the presence of a growing [[wormhole]] created by [[The Swarm (Planet of the Dead)|the Swarm]] which linked central [[London]] to the [[planet]] [[San Helios]].
