Why is Light Speed Invariant & Finite?

Click For Summary
SUMMARY

The discussion centers on the concept of light speed being invariant and finite, specifically emphasizing that infinite speed is unimaginable and leads to logical contradictions in physics. The speed of light is established as 299,792,458 m/s, and the necessity for a universal speed limit across different reference frames is highlighted. The conversation concludes that questioning the fundamental nature of speed and the laws of physics leads to unanswerable inquiries, reinforcing the idea of a fixed value for light speed.

PREREQUISITES
  • Understanding of the theory of relativity
  • Familiarity with the concept of reference frames
  • Basic knowledge of the speed of light as a physical constant
  • Awareness of the implications of infinite speed in physics
NEXT STEPS
  • Research the implications of Einstein's theory of relativity on speed limits
  • Study the concept of reference frames in physics
  • Explore the significance of the speed of light as a universal constant
  • Investigate philosophical questions surrounding the nature of physical laws
USEFUL FOR

Physicists, students of physics, and anyone interested in the fundamental principles of speed and the laws governing the universe.

I think infinite speed is unimaginable. If something is moving at infinite speed, we can't find it at all because it has moved to infinity. Furthermore, when the maximum speed is limited, a reasonable inference should be that observers in different reference frames should find the same one speed limit. It would be unimaginable and incomprehensible if observers in different frames of reference could get different speed limits, which would mean different places in the universe have different laws of physics, unless it was deliberately arranged by the creator.

This post is not about why the speed of light is equal to 299 792 458 m/s, there must be a fixed value anyway.

But then again, the above point of view is of course just my ignorant imagination. I hope to get more in-depth and intelligent comment or response from the experts here.

Your question is unanswerable: it amounts to asking "why are the laws of physics what they are?".
