Is the Speed of Light Affecting Relativistic Phenomena?

Click For Summary

Discussion Overview

The discussion revolves around the implications of varying the speed of light on relativistic phenomena, exploring whether a smaller speed of light would make these phenomena less or more conspicuous. Participants engage with theoretical reasoning and interpretations of relativistic effects in comparison to Newtonian mechanics.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant suggests that if the speed of light were smaller, relativistic phenomena should be less conspicuous, aligning with Newtonian mechanics.
  • Another participant challenges this reasoning, indicating a potential confusion between the speed limit and actual speeds.
  • A different viewpoint posits that with a significantly lower speed of light (e.g., 10,000 m/s), relativistic effects would be more pronounced because achieving relativistic speeds would be easier.
  • Further clarification is offered that the statement about speed should reference the speed relative to the speed of light, which may clarify why lower speeds could lead to more noticeable relativistic effects.
  • Participants acknowledge corrections and express gratitude for clarifications, indicating an ongoing refinement of ideas.

Areas of Agreement / Disagreement

The discussion reflects disagreement regarding the relationship between the speed of light and the visibility of relativistic phenomena, with multiple competing views presented without a clear consensus.

Contextual Notes

Some statements rely on assumptions about the nature of speed and relativistic effects, and the implications of changing a fundamental constant like the speed of light are noted as potentially complex and not straightforward.

if the speed of light were smaller than it is, shouldn't relativistic phenomena be less conspicuous than it is? the smaller the speed, the closer it should be to Newton mechanics...
however my textbook says that it shoud be more conspicuous...
does anybody know what's wrong with my reasoning?

Well what is your reasoning?

You seem to be mixing up the speed limit of something and somethings actual speed.
 
my reasoning is that relativistic phenomena should be less obvious if the speed of light were less than it is...
 
If the speed of light would be 10 000 m/s, the relativistic effects should be MORE obvious than they are now, because it would be easier to achieve relativistic speeds.
 
asdf1, that's a conclusion, not a reasoning

ok, i think i got messed up~
thanks for correcting! :)

It should be "the smaller the speed relative to the speed of light, the closer it should be to Newton mechanics"...and this way of stating it makes it clearer why the effects of relativity would be more conspicuous if the speed of light were lower (although as this page points out, the idea of changing a dimensionful constant like the speed of light may not be very meaningful).
 
thank you! :)
