1x0 Posted March 25, 2015 Author Posted March 25, 2015 Yeah, like the natural numbers can't be infinite because the number 5 exists. What does "the moment of reality" even mean? LOL Now for the whole universe.
Strange Posted March 25, 2015 Posted March 25, 2015 (edited) LOL So you agree you made a laughably stupid and incorrect claim. Good. Now for the whole universe. There is no "now" for the whole universe. Really, don't you think you should learn a little basic maths and physics before making all these claims? Edited March 25, 2015 by Strange
1x0 Posted March 25, 2015 Author Posted March 25, 2015 There is no "now" for the whole universe. Why not?
Strange Posted March 25, 2015 Posted March 25, 2015 Why not? Relativity of simultaneity. http://en.wikipedia.org/wiki/Relativity_of_simultaneity
swansont Posted March 26, 2015 Posted March 26, 2015 How and why? If time has an starting point how can it be infinite in an observed moment of reality? "how can it be infinite in an observed moment of reality?" wasn't the original question. That's just you moving the goalposts. If time has no end, it is infinite, as Strange has more than adequately explained.
ajb Posted March 27, 2015 Posted March 27, 2015 (edited) Why not? Getting technical you can sometimes have a notion of 'now' through a space-time if the space-time is globally hyperbolic. Loosely, this means the space time can be foliated by constant time slices. The FRW solutions are globally hyperbolic, so you can make sense of 'now' throughout the Universe.
