Final answer:
The concept of an object being in 'limbo' if its distance from another is changing is incorrect; such a condition is described as relative motion in physics. Measurements of distance and displacement vary depending on the frame of reference, as shown in Special Relativity with the example of length contraction for a moving muon.
Step-by-step explanation:
The statement that an object is in limbo if its distance from another object is changing is False. The term "limbo" does not correctly describe such a condition in physics. Instead, when the distance between two objects is changing, they are said to be in relative motion. For instance, if we discuss the concept of length contraction in Special Relativity, we deal with measurements of distance and displacement in reference frames. An object may record a non-zero distance while maintaining a displacement of zero if it returns to its starting point after moving. In contrast, an object may record a non-zero displacement while its distance from reference points, such as start and end points, remains unchanged.
These concepts are also evident when discussing frames of reference involving movement, such as a muon moving relative to the Earth. According to the Earth-bound observer, the proper length Lo is measured because the points where the muon is produced and decays are stationary relative to the Earth. However, to the moving muon, these points appear to be moving, and thus the muon measures a different length, denoted as L, which is shorter than Lo due to length contraction.
