The discussion centers on the complexities and implications of dividing by zero, particularly the assertion that expressions like a/0 are undefined. Participants explore the mathematical principles that lead to this conclusion, emphasizing that division by zero would result in every number being equal to every other number, undermining the usefulness of the number system. The conversation also touches on the historical context of mathematical definitions, such as the introduction of negative numbers and imaginary numbers, and how these concepts evolved. Additionally, there is debate about the nature of infinity, with some arguing that certain expressions involving infinity are indeterminate or undefined. The discussion shifts towards philosophical considerations of time and motion, with participants questioning the relationship between time and motion and whether time can exist without motion. Overall, the thread highlights the challenges of defining mathematical operations involving zero and infinity while also delving into broader philosophical implications.

Hey Alkatran, you ever going to concede the point in eot-cat-cit?

Alkatran said:
How do you know time is caused by motion? That makes very little sense. It makes more sense to say motion is caused by the passage of time.

yes, sort of. Actually it is impossible for creaters which are under time and motion, to knwo which one is more fundamental. But if nothing moves then there is no time.

if time is relative to the observer, then it is possible for time not to "flow" at all. like if u observe a foton, it does not have any "flowing" time at all

yes: time is relative. photons, for example, have infinite life, although can be created and destroyed.

This thread has completely digressed from the OP's question, which itself is not a brain teaser, but a question asking for clarification of the definition of the reals.
