MODEL DINAMIKA ALAM SEMESTA DENGAN TEORI BSBM DAN GAS CHAPLYGIN

Abstract

Model alam semesta ini dibangun dengan sumber dinamika berupa densitas medan skalar, densitas radiasi dan densitas energi gelap yang dalam hal ini dikaitkan dengan gas Chaplygin. Aksi dibangun dengan mengintegrasikan teori BSBM dengan model gas Chaplygin. Model matematika yang diperoleh kemudian dianalisis dengan menggunakan sistem dinamika. Trajektori dari model yang dibangun menggambarkan bentuk kestabilan dari model. Nilai eigen yang negatif berkaitan dengan kestabilan dari sistem dan sebaliknya harga eigen positif berkaitan dengan ketidakstabilan. Nilai medan skalar bervariasi sesuai dengan perubahan waktu. Waktu dalam model ini bukan merupakan waktu nyata (waktu kosmik), hanya sebagai parameter yang mengaitkan bahwa nilai medan skalar bervariasi terhadap waktu. Hal ini mengindikasikan bahwa konstanta struktur halus memiliki nilai yang tidak konstan atau dengan kata lain nilainya bervariasi. Hal ini sesuai dengan hasil pengamatan bahwa konstanta struktur halus memiliki nilai yang tidak sepenuhnya konstan.
