Discussion Overview

The discussion centers around the concept of the speed of light as a conversion point for energy, exploring various interpretations and implications of this idea within the framework of special relativity and the expanding universe.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Mathematical reasoning

Main Points Raised

  • One participant challenges the notion that the speed of light is the ultimate conversion point for energy, proposing instead that this point relates to a hypothetical speed equal to the distance around the universe without taking time.
  • Another participant emphasizes that Einstein's equation is derived from the postulates of special relativity, suggesting a foundational basis for the discussion.
  • A different participant argues that if the universe is expanding, then the rest energy of any mass would be constantly increasing, which could conflict with the first law of thermodynamics.
  • Concerns are raised about the mathematical implications of defining a speed that corresponds to traveling around the universe in no time, with references to limits and infinity.
  • One participant mentions a resource for understanding the derivation of E=mc², indicating interest in further exploration of the topic.
  • Another participant notes that, according to special relativity, time would stop for an object reaching the speed of light, implying that it could traverse the universe's perimeter instantaneously.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between the speed of light and energy conversion, with no consensus reached on the validity of the proposed alternative interpretations or the implications of the universe's expansion.

Contextual Notes

Discussions involve assumptions about the universe's finiteness, the implications of its expansion, and the mathematical treatment of speeds approaching infinity, which remain unresolved.

I don't see eye to eye with einstein on this one. how is light speed the conversion point to energy. I think the conversion point for pure energy is at a speed equall to the distance to come all the way around the perimeter of the universe and not take time to do so. So, hypotheticaly speaking, you would see a blur all around the edge of the universe for less than a second.

Einstein did not just concoct this equation because he felt it was pretty. This equation is derived from the two postulates of special relativity.

Darn I just went off on someone for bad grammar and I just reread my last post and it is sprinkled with mistakes. Disregard the last post and read this one...

Since the Universe is expanding, the perimeter of the Universe is constantly changing; which by your reasoning, means that the rest energy of any mass is constantly increasing (because we think the universe is expanding not contracting) That, of course means the 1st Law of Thermodynamics would be broken. Besides if you try to figure out what the "speed equal to the distance to come all the way around the perimeter of the universe and not take time to do so" is you will get infinity. You are dividing a finite number (assuming the Universe is finite which makes sense otherwise how could it expand)by 0 which is basically undefined. But if we put on our calculus hats then we can more or less say it is infinity (calm down math nuts what I meant to say was that the limit as the denominator approaches 0 is infinity).

Besides Chroot is correct.
 
Hmm? Did I miss something?

Anyway, a good website on E=Mc2's derivation:

According to special relativity time will stop if anybody reaches the speed of light (C). If I'm right then it would take no timefor the body to go around the parametre of the universe in no time.
