Discussion Overview

The discussion revolves around Einstein's theory of relativity, specifically addressing the concept of time dilation relative to velocity and the implications of different frames of reference. Participants explore the nuances of how time is perceived differently depending on the observer's frame, including scenarios involving accelerated motion.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant argues that if time slows down relative to velocity, then from the perspective of a rocket traveling away from Earth, time on Earth would also appear to slow down, suggesting that time does not actually slow down but rather depends on the chosen frame of reference.
  • Another participant points out that there are many discussions on this topic, referencing the "twin paradox" and emphasizing that the frame undergoing accelerated motion is the one that experiences time dilation, indicating that the frames are not equivalent.
  • A later reply reiterates that while acceleration is a factor, both frames could experience time differences when they reunite, suggesting that the relationship between acceleration and proper time is more complex than initially presented.

Areas of Agreement / Disagreement

Participants express differing views on the equivalence of frames in the context of time dilation, with some asserting that the frames are not equal due to acceleration, while others challenge this notion, leading to an unresolved debate.

Contextual Notes

The discussion highlights the complexity of time dilation and the role of acceleration, with participants acknowledging that assumptions about frames of reference and their effects on time are not fully resolved.

(move this to my other question please)
As Einstein said that time slows down relative to velocity and he also said that all frames are equally important, then how is the following correct.

If I were in a rocket traveling away from Earth at a distance of V and the Earth was the frame of reference, I would be movinig away at a higher speed and therefor my time would be going slower. But, if the rocket was the frame of reference then the Earth would be moving at a speed of V (where both V's equal the same number). So, in relation to the rocket as the frame, the Earth's time is slowing down so the times even out and become locked, indefinately, so time doesn't slow down at all. This is proven by Einsteins own thought. So time never slows down as it just depends on the frame.

there are dozens and dozens of this same question...do a search for many discussions here . ..TWIN PARADOX...should turn up many.

It is the frame that undergoes accelerated motion which is the "slow" one...the frames are not equal.

This is broadly correct. But both frames could accelerate and still show a time difference when they get back together. It's not the acceleration per se that causes the differential proper times.
