aleph_1 Posted January 28, 2013 Report Share Posted January 28, 2013 Dark matter/energy is just as mythical as Vulcan. It results from an inability to reason from effect to cause, either due to a lack of data or to the insufficiency of current theories. We apply the label "matter" because there seems to be missing mass within galaxies. No, light cannot account for the missing matter. Also, there is no reason to hypothesize the existence of a boundary to the region in the universe where the galaxies reside. No such boundary has ever been observed.

ruveyn1 Posted January 28, 2013 Report Share Posted January 28, 2013 At the moment "dark energy" is just a placeholder for something we do not understand. You have have to call it something so "dark energy" is the current name of the I don't know what that seems to be causing the universe to expand at an accelerating rate. ruveyn1 Quote Link to comment Share on other sites More sharing options...
Grames Posted January 29, 2013 Report Share Posted January 29, 2013 Grames in post 11 said The appeal of this theory is that the underlying existent treats all of the many paths the same without weighting the classical ones more heavily than paths that violate conservation of energy, the least distance principle, or what have you. The underlying existent does not somehow have built into it a priori knowledge of what it is supposed to do, rather much of what we recognize as laws of physics simply falls out of the constructive and destructive summation of all the paths How here do you mean "the underlying existent treats..."? I understand this theory in more laymens' terminology as " a canonball will travel every possible trajectory including the one observed, because String Theory somehow postulates multiverses and since infinity can happen an infinite amount of times , basically you saw one of them." How is what you are, postulating, or quoting, essentially different or is it the same thing ? In path integral computations all of the paths are within the same universe. Bowling balls are not a good tool for understanding by analogy as bowling balls are too big to be considered quantum scale. Quote Link to comment Share on other sites More sharing options...

ruveyn1 Posted January 30, 2013 Report Share Posted January 30, 2013 Entities are entities at any scale. But physical laws are scale dependent. At the atomic and subatomic level entities do not behave according to classical laws. ruveyn1 Quote Link to comment Share on other sites More sharing options...
