Infinite Past and Future: Surprising Consequences of Time Dilation

Click For Summary

Discussion Overview

The discussion revolves around the implications of time dilation in the context of different reference frames in relativity. Participants explore the concept of how one frame can perceive another frame as being in the past or future, and the potential existence of a frame representing an infinite past and future.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that time dilation implies the existence of a frame system that represents both infinite past and future, based on the equation t=t0×γ.
  • Another participant challenges the idea, stating that a frame encompasses the entirety of space and time, and cannot simply be in the past or future of another frame.
  • A third participant acknowledges the complexity of the original post and notes that while different frames can cover space and time differently, the origins can be shifted into the future or past in flat spacetime.
  • A later reply agrees that the idea is not inherently wrong but describes it as "utterly impractical."

Areas of Agreement / Disagreement

Participants express disagreement regarding the interpretation of how frames relate to past and future. There is no consensus on the implications of time dilation as proposed by the original poster.

Contextual Notes

The discussion includes varying interpretations of reference frames and their relationship to time, with some participants finding the original post difficult to understand. There are unresolved aspects regarding the practicality and implications of the proposed infinite past and future frame.

From the equation of time dilation we can deduce a consequence that surprise me . If we know that in our frame system is future and in other frame system is past , and from pointview of the other frame system must be another frame system that is past from our pointview and so on from the equation t=t0\times\gamma where \gamma is einsteinian invariant we can get the following consequence : In our universe must be a frame system that is the infinite past and future. What do you think ? What is wrong and right on this idea ?

Hi GoldNow! :smile:

I'm finding it difficult to understand what you're saying, but if you mean that one frame can be in the past or future of another frame, that's not correct.

A frame covers the whole of space and time.

Two different frames cover the whole of space and time differently, like two different coordinate grids.

Yes, but in flat spacetime the origin certainly can be shifted as far into the future or the past as you might like. I am not sure if that is what the OP intended or not, it is hard to read.

Not wrong but utterly impractical.
