O d\u00f6nemde Ay\u2019\u0131n olu\u015fumuna ili\u015fkin iki temel teori vard\u0131. Birinci teoriye g\u00f6re Ay da t\u0131pk\u0131 D\u00fcnya gibi G\u00fcne\u015f Sistemi\u2019nin olu\u015fumu s\u0131ras\u0131nda gaz ve toz bulutundan, bug\u00fcn bulundu\u011fu yerinde olu\u015fmu\u015ftu. \u0130kinci teoriye g\u00f6re de Ay ba\u015f\u0131bo\u015f gezen bir g\u00f6kcismiyken D\u00fcnya\u2019n\u0131n k\u00fctle\u00e7ekim alan\u0131na girmi\u015f ve bug\u00fcnk\u00fc y\u00f6r\u00fcngesine oturmu\u015ftu. Bir ba\u015fka deyi\u015fle D\u00fcnya, Ay\u2019\u0131 kap\u0131p uydusu yapm\u0131\u015ft\u0131!<\/p>\n

Ay\u2019dan getirilen kayalar Ay\u2019\u0131n olu\u015fumuna y\u00f6nelik bu teorilerin s\u0131nanmas\u0131n\u0131 sa\u011flayacakt\u0131; hangisinin do\u011fru oldu\u011fu ortaya \u00e7\u0131kacakt\u0131. Ne var ki gelen kayalar iki teoriyi de ne tam destekledi ne de tam olarak \u00e7\u00fcr\u00fctt\u00fc. Bu kayalar D\u00fcnya\u2019dakilerden biraz farkl\u0131yd\u0131lar. \u00d6yleyse D\u00fcnya\u2019dakilerle ayn\u0131 s\u00fcre\u00e7lerden ge\u00e7erek olu\u015fmu\u015f olamazlard\u0131. Ayr\u0131ca Ay da D\u00fcnya ile ayn\u0131 \u015fekilde, onunla benzer bir s\u00fcre\u00e7ten ge\u00e7erek olu\u015fmu\u015f olsayd\u0131 t\u0131pk\u0131 onunki gibi b\u00fcy\u00fck\u00e7e bir demirden \u00e7ekirde\u011fi olmas\u0131 gerekirdi; ama yoktu.\u00a0 \u00d6te yandan Ay kayalar\u0131 meteoritlerden farkl\u0131yd\u0131lar ve D\u00fcnya\u2019daki kayalarla da bir\u00e7ok ortak y\u00f6nleri vard\u0131. O zaman Ay ile D\u00fcnya\u2019n\u0131n ortak bir ge\u00e7mi\u015fi de olmas\u0131 gerekiyordu. Zaten D\u00fcnya\u2019n\u0131n, yak\u0131ndan ge\u00e7mekte olan Ay kadar b\u00fcy\u00fck bir g\u00f6kcismini yolundan \u00e7evirip de kendi \u00e7evresinde d\u00f6nmeye zorlayacak bir k\u00fctlesi yoktu.<\/p>\n

Ne var ki Ay kadar k\u00fc\u00e7\u00fck bir g\u00f6kcisminin y\u00fczeyi do\u011fal olarak hi\u00e7bir zaman b\u00f6ylesine \u0131s\u0131nm\u0131\u015f olamazd\u0131. Ay\u2019dan gelen kayalar sayesinde Ay\u2019\u0131n k\u00f6keninin gizemi \u00e7\u00f6z\u00fclememi\u015f hatta tersine gizem biraz daha derinle\u015fmi\u015fti. Ay\u2019\u0131n D\u00fcnya kadar ya\u015fl\u0131 oldu\u011fu, Ay\u2019da hi\u00e7 su bulunmad\u0131\u011f\u0131, oradaki kayalar\u0131n D\u00fcnya\u2019n\u0131n mantosundaki kayalara benzedi\u011fi, \u00e7ok az demir i\u00e7erdikleri ve bir zamanlar Ay\u2019\u0131n y\u00fczeyinin t\u00fcm\u00fcyle eriyik oldu\u011fu anla\u015f\u0131lm\u0131\u015f oldu. Sanki Ay ile D\u00fcnya ayn\u0131 s\u00fcre\u00e7lerden ge\u00e7erek olu\u015fmu\u015ftu; ama sonra Ay \u00e7ok \u0131s\u0131nm\u0131\u015f, erimi\u015fti ve demir \u00e7ekirde\u011fini de bir \u015fekilde yitirmi\u015fti.<\/p>\n
