Information relativity theory solves the twin paradox symmetrically

摘要

The twin paradox is one of the most fascinating paradoxes in physics. In special relativity, the paradox arises due to the nonexistence of a preferred frame of reference, resulting in both twins observing that he or she is younger than the other twin. Nonetheless, it is commonly agreed that the "traveling" twin returns younger than the "staying" twin. The prevailing solution is obtained by deviating from the relativity principle and assuming that the "staying" twin's frame is preferred over the "traveling" twin's frame. Here, I describe a newly proposed relativity theory, termed information relativity, and show that it solves the twin paradox symmetrically, with the twins aging equally.
