[quote]consider this what if the objects themselves were expanding [u]all objects[/u] ...this would also include even the measuring devices...therefore it would be impossible to measure or even be aware of the expanding objects[/quote] If all objects in the universe are expanding, as space itself is expanding, the object has not changed in size (relatively) which is why you wouldn't be able to measure the difference - the net result concurs somewhat with your observation, and is more-or-less the truth. The following article is quite handy, and the explanation sounds blindingly simple... yet I marvel at the intelligence of those who [i]first[/i] wondered at, and developed an empirical methodology for the most profound aspects of our Universe. [url=http://en.wikipedia.org/wiki/Metric_expansion_of_space]Metric Expansion of Space[/url] On a side note, if you've ever wondered why the night sky isn't full of light ([i]effectively[/i] infinite space and all the matter in it, filling the sky an' all), it all seems to tie-in nicely with the [url=http://csep10.phys.utk.edu/astr162/lect/cosmology/expansion.html]expanding universe[/url], too... [quote]An infinite number of points is NOT impossible. In Continuous math you have infinite number of points on a curve.[/quote] ...and an infinite number of imaginary pink bunnies can exist too, but in the real world, there is no way to physically represent it. Infinity itself is as abstract and imaginary as 'zero', or a two-dimensional object (such as a circle). A rainbow may appear to be a perfect circle, but that is only as you perceive it - one imperceptible photon out of place and your crude human eye may still perceive what appears to be a perfect curve, but it's still a bombardment of the retina with a finite (though stonkingly vast) number of photons. _____ Thinking out loud: I remember reading once that a perfect crystal cannot exist as, by definition, it would be boundless, and that would leave no room for anything else in the universe. I wonder how profoundly impossible 'perfect' is; it's another relative or abstract concept, isn't it? Nothing is perfect. Loading...
