Discussion Overview

The discussion revolves around the implications of relativity on the perception of dimensions, particularly in relation to the extra dimensions proposed by string theory. Participants explore how relativistic speeds might affect the visibility or size of these dimensions.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests that as an object moves faster, all dimensions of time, including the extra dimensions from string theory, might change in size relative to the observer.
  • Another participant counters that it seems unlikely for extra dimensions to expand from the observer's viewpoint, noting that relativistic speeds typically cause spatial dimensions to contract rather than expand.
  • A different viewpoint mentions that while one length dimension contracts in the direction of travel, all other spatial dimensions, including the extra dimensions, remain unchanged from the perspective of the moving observer.
  • There is speculation about the possibility of extra dimensions being time dimensions and how time dilation might affect their size, though this remains uncertain.

Areas of Agreement / Disagreement

Participants express differing views on how relativistic speeds affect dimensions, with no consensus reached on the implications for extra dimensions in string theory.

Contextual Notes

Participants acknowledge various assumptions about the nature of dimensions and the effects of relativity, but these assumptions remain unresolved and are dependent on interpretations of string theory and relativity.

I was just think about relativity, and as you move faster how distances and the amount of time seems to change as you speed up. This means that all dimensions of time (including the extra 6 from string theory that are extremely small dimensions) would seem to change as you move faster. so, I was wondering if something is moving fast enough the extra 6 space dimensions, ussually two small to be seen, might change in size relative to you, making them large enough to be visible? Correct me if I am wrong about any of the above thoughts, including any misunderstandings I have of rletivity. Thanks for input.

An interesting thought. It would seem unlikely that the extra dimensions expand from the observer's viewpoint, as travel at relativistic speeds will tend to make spatial dimensions smaller, not larger. At near-light speeds, lengths contract and time dilates.

However, I recall reading once that in some models of string theory, one or more of the extra dimensions might be an extra time dimension. If this is correct, then perhaps time dilation will cause this extra dimension to expand. But that's pure speculation, of course. I don't even know what that would mean in terms of observing or measuring the change.
 
When you speed up to almost light speed, the stationary observer sees your clock appearing to slow down and ONE length dimension shorten, namely the one in the direction you're going. All other spatial dimensions are unchanged, including the six extra dimensions from string theory. As far as your concerned, everything is fine.
 
That makes sense.
