Kosmologi fisik |

Dalam kosmologi fisik, inflasi kosmik atau inflasi adalah pengembangan eksponensial alam semesta muda dengan faktor 1078 untuk volume, yang didorong oleh kepadatan energi vakum bertekanan negatif.[1] Periode inflasioner meliputi bagian pertama periode elektrolemah setelah periode penyatuan agung. Periode ini berlangsung dari 10−36 detik setelah Ledakan Dahsyat hingga 10−33 dan 10−32 detik. Setelah periode inflasioner, alam semesta terus mengembang, namun dengan laju yang lebih lambat.
Istilah "inflasi" juga merujuk kepada hipotesis bahwa inflasi pernah terjadi. Hipotesis ini pertama kali diusulkan pada tahun 1980 oleh fisikawan Amerika Serikat Alan Guth.[2] Teori ini juga diusulkan oleh Katsuhiko Sato pada tahun 1981.[3]
Teori inflasi menjawab permasalahan klasik dalam kosmologi Ledakan Dahsyat: mengapa alam semesta tampak datar, seragam, dan isotropik, sementara berdasarkan fisika Ledakan Dahsyat, alam semesta seharusnya melengkung dan beragam? Inflasi juga menjelaskan asal usul struktur kosmos yang besar.
Sementara mekanisme fisika partikel yang menyebabkan terjadinya inflasi masih belum diketahui, gambaran dasarnya memungkinkan beberapa prediksi yang telah dipastikan melalui pengamatan. Maka, inflasi saat ini dianggap sebagai bagian dari kosmologi Ledakan Dahsyat. Partikel atau medan dasar yang diduga menyebabkan terjadinya inflasi disebut inflaton.
Catatan kaki
[sunting | sunting sumber]- ^ Liddle and Lyth (2000) and Mukhanov (2005) are recent cosmology text books with extensive discussions of inflation. Kolb and Turner (1988) and Linde (1990) miss some recent developments, but are still widely used. Peebles (1993) provides a technical discussion with historical context. Recent review articles are Lyth and Riotto (1999) and Linde (2012). Guth (1997) and Hawking (1998) give popular introductions to inflation with historical remarks.
