Mesaj: <blockquote data-quote="Akademik Forum" data-source="post: 463670">...The basic idea of a brane world is that our three-dimensional universe is a subuniverse embedded in a larger space of four or more spatial dimensions. The three-dimensional universe is called a brane, and the larger universe is called the bulk. All known forms of matter and energy are stuck to our three-dimensional brane like a movie projected on a screen (or the shadow reality for Plato's prisoners in the cave). The exception is gravity, which permeates all of the higher-dimensional bulk.Let's think about the bulk suprauniverse of four spatial dimensions that may have existed before the big bang. We can imagine that this bulk universe was filled with objects such as four-dimensional stars and four-dimensional galaxies. "These higher-dimensional stars might run out of fuel, just as our three-dimensional stars do, and collapse into black holes"....Bu sorunun kaynagi da burasiymis : <a href="http://palgrave.nature.com/scientificamerican/journal/v311/n2/full/scientificamerican0814-36.html" target="_blank">http://palgrave.nature.com/scientificamerican/journal/v311/n2/full/scientificamerican0814-36.html</a> ve cevap dogal olarak run out of aciklandigi gibi. Zaten secenekleri okuyunca cevap acik bir sekilde buradayim diyordu.Gercekten de bu tarz sinavlara hazirlanirken rutin olarak okudugunuz makale, bildiri vb. yayinlarin yaninda Scientific American vb. kaynaklarin arsivlerine goz atip firsat buldukca okumakta fayda var gibi gorunuyor. Umarim sonuclar bu hafta aciklanir ve bizler acisindan iyi olur..</blockquote>
