Light speed relative to universal speed

Click For Summary

Discussion Overview

The discussion revolves around the concept of light speed in relation to a proposed "universal speed through time." Participants explore the implications of this idea, questioning its validity and clarity, while also discussing the nature of time and relativity.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • One participant suggests that a photon travels at "relativistically zero velocity" relative to the universe's speed through time, seeking confirmation of this idea.
  • Another participant expresses confusion about the term "universe's speed through time" and questions the meaning of "the universe" and its perception of time.
  • Several participants indicate that they find the original proposition nonsensical or difficult to understand, particularly due to a lack of clarity in the accompanying diagram.
  • One participant interprets the diagram as illustrating a simple relationship between the speed of light and the passage of time, suggesting that it may not be as profound as implied.
  • Another participant proposes that the diagram's elements symbolize "universal change," attempting to clarify its meaning for others.
  • A later post introduces a perspective that connects the speed of light to the existence of dimensions in spacetime, suggesting that time travel leads to parallel universes, although this view is not directly related to the original question.

Areas of Agreement / Disagreement

Participants generally express disagreement and confusion regarding the original proposition and its implications. There is no consensus on the validity or clarity of the ideas presented.

Contextual Notes

Some participants note the lack of labels in the diagram, which contributes to their confusion. The discussion also highlights varying interpretations of relativity and the relationship between speed, time, and universal change.

Light speed relative to universal speed...

HI guys,

Just a simple request for confirmation that I have it right.

It may seem so obvious to you but to me I just need to confirm with currently held thought ( this forum ) that the photon travels at relativistically zero velocity with the universe's speed through time...

The diagram I think shows this fundamental clearly enough. Is the diagram correct in it's proposition?
( the figure given for 'c' is relative to ambience of course)

Thanks

makes sense to me but I am no graduate of relativity
 
What's the "universe's speed through time?" More particularly, what's "the universe," and how can it perceive time?

It makes no sense to me.
 
whitelighter,

Integral said: "It makes no sense to me"

I will raise that to the level of a postulate and say that the sense of your post is a universal constant, equal to zero in all frames of reference. :wink:
 
It makes no sense to me.

Integral, from the other posts I have seen you obviously are a member of some esteem and maybe I can learn from your opinion.

To me this contention is just utilising relativity to describe the "Time Continuum" and suggests another approach to the way relativity can be applied...

Can you explain why this contention is nonsense as this would help me understand my own error of "looking"?

(BTW I have tried to find whitelighter but he/she appears to be no longer a member of this board)
 
Unfortunately when I say "this makes no sense to me" That is what I mean. I am unable to understand the meaning of his picture. He really does not label the bars that appear. If you can explain to me what those are supposed to represent, perhaps I could begin to relate this to what I do understand.
 
I think the diagram is probably just to simple and we are looking for more than it is...

It obviously shows a spread of time (10 seconds) as an example.

It shows that a photon travels 3M kms in that 10 seconds and that the universes changes in that same 10 seconds...

And that's it...nothing more

Self evident and not all that profound I might add.

But where is see the value is in the combining of "c" with the contention that because "c' is the threshold that time may reverse if exceeded may lead to the idea that velocity beyond stationary will create time slowing effects.

"because a relatively stationary universe is already at 'c'..." "that velocities beyond "stillness" will produce time distortion effects

Anyway that's what I understand from his/her POV on relativity...I have no idea how this may or may not effect the understanding of anything...to me it's just an abstraction and is valued as such.
 
those little boxes I would presume are symbolising universal change.

is that of any help Integral?

b = magnetism

--------------------------------------------------------------------------------

The speed of light directly supports how dementions there are in space time that's why when you time travel you go to a parallel universe. Speed of light is in increments of 8 the speed of light is only for finding new dementions not for traveling. Look up Quantum time port where time and space are the same place. Who cares about the speeed of light. Time is controlled by the speed of b = magnetism
