Question

The question explores the fascinating realm of time perception in the context of General Relativity and thermodynamics. The idea that moving away from an observer at high speed might result in the observer going backward in time is debunked, emphasizing that observers would instead experience disagreements in space-time coordinates and clock rates. The discussion extends to Einstein's views on Thermodynamics, highlighting the significance of Brownian Motion in supporting Boltzmann's ideas about the existence of atoms.

In the realm of thermodynamics, the relationship between time, information, and entropy is expounded. The assertion that time is about information and correlations spreading out is explained, drawing on the concept of isolated quantum systems and their wavefunctions governed by Conservation Laws. The time-independence suggested by the Wheeler-DeWitt equation is presented as a crucial step in reconciling Relativity and Quantum behavior.

The narrative delves into Feynman's perspective on antiparticles and their behavior resembling particles, seemingly going 'backwards' in time. The rejection of this notion's physical reality by Feynman and its acceptance by Wheeler, particularly in the context of the One Electron Universe, adds depth to the exploration.

The metaphor of a sea of ripples, quantum interference, and the analogy of an isolated quantum system with full dimensionality further enrich the discussion. The concept of higher dimensionality, linked to the Conservation of Information and the 'No Hiding Theorem,' is introduced, providing a theoretical framework for understanding the asymmetric symmetry in the direction of time.

The TL;DR section succinctly summarizes the key points, emphasizing that while specific perspectives might suggest objects going backward in time, signals cannot, given the concentration of information required for true backward time travel, leaving no trace. The reference to the Andromeda 'paradox' adds a real-world dimension to the theoretical discourse, challenging perceptions of time in relative motion. What does an observer perceive when someone moves away at high speed according to General Relativity?

a. The observer sees the moving person going backward in time.

b. The observer sees the moving person getting younger.

c. The observer sees the moving person aging more slowly or quickly.

d. The observer experiences time stopping altogether.

Answer 1

According to General Relativity, when someone moves away at high speed, the observer perceives the moving person aging more slowly or quickly due to time dilation.

Step-by-step explanation:

According to General Relativity, when someone moves away from an observer at high speed, the observer perceives the moving person aging more slowly or quickly. According to General Relativity, when someone moves away at high speed, the observer perceives the moving person aging more slowly or quickly due to time dilation.

This is because in the presence of gravity or high speed, time dilation occurs, causing a discrepancy in the passage of time between the observer and the moving person. The stronger the gravity or the higher the speed, the greater the difference in the perception of time between the two observers.
