As others have pointed out there may be some numbers that are off at the very end of the big scale stuff. That doesn't mean this whole thing is "theories". What do you even mean by that anyway? If you want to get all technical and argue semantics, then yes, "most" was a poor choice of word. "some" of it was theories. Nobody has measured the galaxy, and that approximation can not be proved, thus it is a theory. | ||

You realize you can never measure something with 100% accuracy unless you define you unit by what you are measuring, all other measurements are subject to error. | ||

this topic is something i think about really often and even read crazy theoretic physics books in my free time. if you are really into those ideas i have to add some great stuff which blows your mind: 1. the millennium simulation http://www.mpa-garching.mpg.de/galform/press/ go check the site and make sure u look at the pics in highest res. than take some time to think about it and once you start to scratch the wohle thing your mind will go boooom (i recoment downloading the [poster.ps.gz, A0, 280 MB] its really worth it!) one thing more to note: when u look at those pictures keep in mind that each tiny spot of light is a whole GALAXY! (most amazing after seeing the zoom in/out youtube video!) 2. to go into it deeper i would recoment reading that: http://en.wikipedia.org/wiki/General_relativity and read it often, like OFTEN i think i read it through a bazillion times to get rdy for next point (i admit u have to be insane to go further in freetime but i know im crazy  3. next step is based on basic grasp on relativity and how you can "visualize" it: Imagining the tenth dimension part1/2 Imagining the tenth dimension part2/2 If you got so far -> some help: remember to imagine any dimension above the 3rd with the help of the second ("fold" the lower dimension to get into a higher one). this is so important to understand anything above 5th/6th. without the "folding" my brain told me after 6th: "lol wut?i can haz cookiez? after all that mindblowing stuff go back and watch the whole "how big is our universe" again!!!! who needs drugs when wiki and youtube can do better for free!
