Einstein’ın genel görelilik teorisi orta ölçeklerde (örneğin güneş sisteminde, dünyada) kütle-çekim etkileşimini çok iyi anlatmaktadır. Ancak, çok küçük ve çok büyük mesafelerde (mikroskobik boyutlarda ve galaksi, evren boyutunda) teorinin yetersiz kaldığı bilinmektedir. Bir kısım galaksilerdeki yıldızların dönme hızlarının izahı ve evrenin ivmelenerek genişlemesi, teorinin açıklayamadığı büyük ölçek sorunlarıdır. Diğer yandan kara deliklerdeki ve evrenin başındaki tekilliklerin izahı küçük ölçek sorunlarıdır. Bu sorunlar nedeniyle, teorinin daha tutarlı bir teori içine yerleştirilmesi beklenmektedir. Projede genel görelilik teorisinin özelliklerine sahip ama özellikle küçük mesafelerde daha tutarlı bir model oluşturmayı öngördük ve bunu gerçekleştirdik. Oluşturduğumuz modelin bir kısım kara delik tipi ve enflasyon kozmolojisi çözümlerini inceledik. Beklediğimiz gibi, modelimiz genel göreliliğe kıyasla daha iyi sonuçlar vermektedir. Örneğin, statik, küresel simetrik çözümlerin tekillik sorunu çözülmektedir.

Black hole collisions at the speed of light Şentürk, Çetin; Karasu, Atalay; Department of Physics (2010) The main purpose of this work is to study the collision of two black holes and the energy loss due to the gravitational waves emitted during this collision in the framework of general relativity. For this purpose we first study plane wave geometries and their collisions. More realistic collisions are the pp-wave collisions. As an analytic treatment of this problem, we investigate the head-on collision of two ultra-relativistic black holes. Treating the problem perturbatively, we extract the news function to...
Gravitational Waves and 2.5 PN Gravitational Wave Memory Uçanok, Onur; Tekin, Bayram; Department of Physics (2020-9) Since the discovery of general relativity, the Einstein field equations have explainedmany phenomenon (e.g. precession of orbits) and predicted others (e.g. gravitational lensing, gravitational time dilation and black holes). Among its many predictions,the wave-like nature of the linearized theory has garnered a lot of attention due to the possiblity of gravitational wave propagation; their effects, their observability andthe complicated nature of gravitational radiation. Many scientists (that can be foun...
Kerr black holes and their generalizations Cebeci, Hakan; Karasu, Emine Ayşe; Dereli, Tekin; Department of Physics (2003) The scalar tensor theory of gravitation is constructed in D dimensions in all possible geometries of spacetime. In Riemannian geometry, theory of gravitation involves a spacetime metric g with a torsion-free, metric compatible connection structure. If the geometry is non-Riemannian, then the gauge theory of gravitation can be constructed with a spacetime metric g and a connection structure with torsion. In non-Riemannian theory, connections may be metric compatible or non-metric compatible. It is shown that...
Gödel Spacetime Kavuk, Mehmet; Sarıoğlu, Bahtiyar Özgür; Department of Physics (2005) In this thesis properties of the Gödel spacetime are analyzed and it is explicitly shown that there exist closed timelike curves in this spacetime. Geodesic motions for massive particles and light rays are investigated. One observes the focusing effect as a result of the solution of the geodesic equations. The time it takes for a free particle released from a point to come back to its starting point is calculated. A geometrical interpretation of the Gödel spacetime is given and the question of what the Göde...
A physical model for dimensional reduction and its effects on the observable parameters of the universe Karaca, Koray; Bayın, Selçuk; Department of Physics (2005) In this thesis, assuming that higher spatial dimensions existed only during the inflationary prematter phases of the universe, we construct a (1+D)-dimensional (D>3), nonsingular, homogeneous and isotropic Friedmann model for dimensional reduction. In this model, dimensional reduction occurs in the form of a phase transition that follows from a purely thermodynamical consideration that the universe heats up during the inflationary prematter phases. When the temperature reaches its Planck value Tpl,D, which ...
