\u2013\u00a0Ba\u015fka nelerden olu\u015fuyorsunuz?<\/em><\/strong><\/p>\n

\u00a0\u2013\u00a0<\/em><\/strong>Sizi atomlar\u0131n toplam\u0131 olmakla itham etsem, nas\u0131l hissederdiniz?<\/p>\n

\u2013\u00a0Tabii ki hakl\u0131s\u0131n\u0131z. Densizlik etti\u011fim i\u00e7in kusuruma bakmay\u0131n, amac\u0131m sizi k\u00fc\u00e7\u00fck g\u00f6rmek de\u011fildi. Bize kendinizden s\u00f6z etmek ister miydiniz?<\/em><\/strong><\/p>\n

\u2013 Elbette, g\u00f6rd\u00fc\u011f\u00fcn\u00fcz gibi, bir ba\u015ftan bir ba\u015fa yakla\u015f\u0131k 100.000 \u0131\u015f\u0131k y\u0131l\u0131 uzunlu\u011funday\u0131m ve orta b\u00f6lgemdeki g\u00f6be\u011fim hari\u00e7 d\u00fcze yak\u0131n\u0131m. Buna ek olarak, en basitinden s\u00f6ylersek, \u00e7evremde geni\u015f bir k\u00fcresel da\u011f\u0131l\u0131m g\u00f6steren b\u00fcy\u00fck bir halem var.<\/p>\n

\u2013\u00a0I\u015f\u0131k y\u0131l\u0131, \u0131\u015f\u0131\u011f\u0131n bir y\u0131lda seyahat etti\u011fi mesafe midir?<\/em><\/strong><\/p>\n

\u00a0\u2013\u00a0<\/em><\/strong>Evet, yakla\u015f\u0131k olarak 9,5 trilyon kilometredir. Yakla\u015f\u0131k 10 milyar y\u0131ld\u0131z, geni\u015f hidrojen bulutlar\u0131, karadelikler, k\u0131rm\u0131z\u0131 devler, beyaz c\u00fcceler, say\u0131s\u0131z G\u00fcne\u015f Sistemi, y\u0131ld\u0131zs\u0131z devasa gezegenler, n\u00f6tron y\u0131ld\u0131zlar\u0131, pulsarlar, g\u00f6remedi\u011finiz madde, manyetik alan ve zengin yap\u0131lar i\u00e7eriyorum; en belirgin \u00f6zelli\u011fim de, b\u00fcy\u00fck spiral kollar\u0131md\u0131r.<\/p>\n

\u2013\u00a0Nas\u0131l ve nerede bi\u00e7imlendi\u011finizden s\u00f6z eder misiniz?<\/em><\/strong><\/p>\n

\u2013 Her \u015fey Evren \u00e7ok gen\u00e7ken ve h\u0131zla geni\u015fliyorken ba\u015flad\u0131. O zamanlar, yani yakla\u015f\u0131k 10 milyar y\u0131l \u00f6nce, Evren b\u00fcy\u00fck oranda hidrojen, biraz helyum ve \u00f6nemsiz birka\u00e7 \u015feyden daha olu\u015fuyordu; hepsi bu kadard\u0131. Evren \u00e7ok s\u0131k\u0131c\u0131 olacakm\u0131\u015f gibi g\u00f6r\u00fcn\u00fcyordu; s\u00fcrekli geni\u015flemekle me\u015fgul karanl\u0131k bir uzay. O ilk g\u00fcnlerden bizim bug\u00fcnk\u00fc ko\u015fullar\u0131m\u0131z\u0131 tahmin etmek, daha a\u011fa\u00e7 dikilmeden, yapra\u011f\u0131n\u0131n nereye d\u00fc\u015fece\u011fini \u00f6ng\u00f6rmeye benziyor.<\/p>\n

\u2013\u00a0Ne oldu?<\/em><\/strong><\/p>\n

\u2013 Evren geni\u015flerken i\u00e7indeki hidrojen d\u00fczg\u00fcn bir da\u011f\u0131l\u0131m g\u00f6stermedi. Baz\u0131 b\u00f6lgelerde toplanm\u0131\u015ft\u0131; buralarda \u00f6teki b\u00f6lgelerdekinden yaln\u0131zca k\u00fc\u00e7\u00fck bir miktar daha yo\u011fundu.<\/p>\n

\u2013\u00a0Plajda insanlar\u0131n grupla\u015fmas\u0131 gibi mi?<\/em><\/strong><\/p>\n

\u2013 Evet, bir farkla, atomlar do\u011fan\u0131n yasalar\u0131n\u0131 izler, toplumsal yasalar\u0131 de\u011fil.<\/p>\n

\u2013\u00a0Elbette, peki sonra ne oldu?<\/em><\/strong><\/p>\n

\u00a0\u2013\u00a0<\/em><\/strong>Sonra Evren\u2019in geni\u015flemesi \u00f6nemsiz hale geldi; y\u00fcksek yo\u011funluklu b\u00f6lgeler, kendi k\u00fctle\u00e7ekim alanlar\u0131n\u0131n etkisiyle \u015fekillenmeye ba\u015flad\u0131lar. Tabii ki, i\u00e7 i\u00e7e ge\u00e7mi\u015f \u015fekillenmeler vard\u0131; b\u00f6ylelikle g\u00f6kada olu\u015furken, y\u0131ld\u0131zlar ve g\u00fcne\u015f sistemleri de olu\u015ftu.<\/p>\n

\u2013\u00a0Yani olu\u015fumunuz b\u00f6ylece tamamland\u0131?<\/em><\/strong><\/p>\n

\u00a0\u2013\u00a0<\/em><\/strong>Hay\u0131r, hen\u00fcz de\u011fil. Bu g\u00f6kada k\u00fc\u00e7\u00fckt\u00fc ve ilk g\u00f6kadalar\u0131n \u00e7o\u011fu gibi, yaln\u0131zca yakla\u015f\u0131k 50 milyon g\u00fcne\u015f k\u00fctlesindeydi. Bununla birlikte, yak\u0131n \u00e7evresinde onun gibi \u00e7ok say\u0131da g\u00f6kada vard\u0131. Bunlar giderek birbirlerine yak\u0131nla\u015fmaya ba\u015flad\u0131lar. Birka\u00e7 milyar y\u0131l i\u00e7inde de b\u00fct\u00fcnle\u015ftiler ve\u2026 \u0130\u015fte kar\u015f\u0131n\u0131zday\u0131m.<\/p>\n

\u2013\u00a0G\u00f6r\u00fcyorum, ama sizin b\u00fcy\u00fck sarmal kollar\u0131n\u0131z\u0131 da merak ediyorum.<\/em><\/strong><\/p>\n

\u00a0\u2013\u00a0<\/em><\/strong>Onunkiler \u00f6yle, benimkiler de\u011fil. Ger\u00e7ekte olan \u015fudur: \u00c7evremde bir yo\u011funluk dalgas\u0131 yay\u0131l\u0131r, bu s\u0131rada gazlar\u0131 bir b\u00f6lgede s\u0131k\u0131\u015ft\u0131r\u0131r, bir ba\u015fkas\u0131nda seyreltir. Y\u0131ld\u0131zlar bir sarmal kol b\u00f6lgesine girerken yava\u015flarlar ve birbirlerine do\u011fru itilerek yak\u0131nla\u015f\u0131rlar. Bu harika s\u00fcre\u00e7, yeni y\u0131ld\u0131zlar\u0131n do\u011fumunu tetikler.<\/p>\n
