Final answer:
The provided information about relativistic quantum mechanics, which includes Einstein's theory of relativity, aligns with the concepts of relativity and points out the necessity of having a frame of reference to describe motion, similar to Descartes' views. It does not support the notion of absolute existence, as it emphasizes the observer's perspective in physics. d) It aligns with Descartes' views on motion is correct answer.
Step-by-step explanation:
The provided information discusses how relativistic quantum mechanics unifies Einstein's theory of relativity with classical mechanics or quantum mechanics. This unification is significant because it provides explanations for objects of all sizes and masses, which contributes to our understanding of the universe.
Particularly, it touches upon the nature of the laws of physics being the same in all inertial frames of reference, and the constancy of the speed of light according to Einstein's postulates of special relativity.
When addressing the question about absolute existence and relativity, the information supports the concept of relativity (option b), aligns with Descartes' views on motion and the necessity of a frame of reference to describe position or motion (option d), and hints at a universal applicability of physical laws, somewhat in the spirit of Advaita philosophy that talks about non-dualism or universality (option c).
However, it does not support the concept of absolute existence, as the theory of relativity itself is based on the premise that measurements and physical laws are dependent on the observer's frame of reference.
Therefore, the most fitting answer to the student's question appears to be option d - it aligns with Descartes' views on motion, as Descartes also discussed the relativity of motion and the importance of the observer's perspective when describing motion.
