According to special relativity, distances are relative, as people measuring distance from different reference frames come up with different measurements and are equal on footing as regards their results. However, my question is then: how can we even define a given length, for example, the Planck length to be 10^-33 cm, if it is also subject to special relativity and therefore not even an absolute reference? Also (this is more of a philosophical question), can length even be assigned as a quality of an object or is it just an illusion from our reference frame?
