Bir galaksiyi tartmak, \u00f6zellikle de i\u00e7inde otururken, kolay bir i\u015f de\u011fildir. Tucson Arizona \u00dcniversitesi\u2019nden astronom Ekta Patel, Live Science<\/i>\u2019a verdi\u011fi deme\u00e7te, \u201cABD n\u00fcfusunun bir n\u00fcfus say\u0131m\u0131n\u0131 yapmaya \u00e7al\u0131\u015fmak gibi, ama interneti kullanamazs\u0131n\u0131z ve ya\u015fad\u0131\u011f\u0131n\u0131z \u015fehri terk edemezsiniz\u201d diyor.<\/p>\n
Hi\u00e7 kimse Samanyolu\u2019nu kozmik bir \u00f6l\u00e7ekte tutamaz ve \u00f6ylece sonucu okuyamaz. Problemin bir k\u0131sm\u0131, bir galaksinin k\u00fctlesinin \u00e7o\u011funun g\u00f6r\u00fcnmez olmas\u0131d\u0131r. Patel, Samanyolu\u2019nun y\u00fczde 85\u2019inin hen\u00fcz tam olarak belirlenemeyen karanl\u0131k maddeden olu\u015ftu\u011funu s\u00f6yl\u00fcyor. Bu y\u00fczden galaksimizdeki y\u0131ld\u0131zlar\u0131 basit\u00e7e saymak, sorunu \u00e7\u00f6zmez.<\/p>\n
