Joseph B Posted July 10, 2011 Share Posted July 10, 2011 I never even thought about galaxy sizes before, it never crossed my mind they actually varied in size... Makes sense I suppose considering how it seems like every where you look in the universe, everything seems completely unique from each other.

neoadorable Posted July 11, 2011 Share Posted July 11, 2011 that last one is huge...it seems so bright, there may well be no night on any world there....kinda like our own galaxy's core. Link to comment Share on other sites More sharing options...
guru Posted July 12, 2011 Share Posted July 12, 2011 here what i dont understand .. they say universe is uniform in any direction you look, then you have such large variation in shapes and sizes of everything from starts to galaxies :unsure: Link to comment Share on other sites More sharing options...
neoadorable Posted July 18, 2011 Share Posted July 18, 2011 who says the universe is uniform every way you look? no, i think they mean the overall shape of the universe, which is currently not really known and still a theory. Link to comment Share on other sites More sharing options...
guru Posted July 18, 2011 Share Posted July 18, 2011 who says the universe is uniform every way you look? no, i think they mean the overall shape of the universe, which is currently not really known and still a theory. The observable matter is spread homogeneously (uniformly) throughout the universe, when averaged over distances longer than 300 million light-years. ... http://en.wikipedia.org/wiki/Universe observation not theory.. Its light has taken 349.5 million years to travel to Earth. IC 1011's calculated age is approximately 12.95 billion years http://en.wikipedia.org/wiki/IC_1011 Link to comment Share on other sites More sharing options...
neoadorable Posted July 19, 2011 Share Posted July 19, 2011 i guess think of the cosmos as either a sphere or a sheet of glass or a tube, so no matter where you stand, it's the same shape. but the stuff that's put on that sheet of glass or tube, or in that sphere, can be of all different manner of shapes and sizes due to the somewhat random makeup of natural forces and processes.

DocM Posted July 19, 2011 Share Posted July 19, 2011 An interesting current speculation is a membranous shell with "reality" consisting of holographic data points projected as 3D into its interior. This solves a lot of problems in physics. Some think that this shell is a dodecahedron. Link to comment Share on other sites More sharing options...

DocM Posted July 19, 2011 Share Posted July 19, 2011 It started with a 2003 article in Scientific American about how holographic data principles could explain a few problems - Teaser: http://www.scientificamerican.com/article.cfm?id=information-in-the-hologr-2003-08 Archived: http://sufizmveinsan.com/fizik/holographic.html and the idea of a dodecahedron universe - http://physicsworld.com/cws/article/news/18368 Then this happened in 2009 at a gravitational wave detector - http://www.sciencedaily.com/releases/2009/02/090203130708.htm And then this - http://www.sciencedaily.com/releases/2009/02/090203081609.htm That lead to this experiment starting construction in 2010 - http://www.wired.com/wiredscience/2010/10/holometer-universe-resolution/ and now theories are flying out of the labs, some blending holographic with dodecahedron and the idea of 3D space being a projection.
