    Sammanfattning : General relativity (GR) is the standard physical theory describing gravitational interactions. All astrophysical and cosmological observations are compatible with its predictions, provided that unknown matter and energy components are included. These are called dark matter and dark energy.

  3. 2. Symmetries and black holes in Hassan–Rosen bimetric theory

    Författare :Francesco Torsello; Edvard Mörtsell; Mikael von Strauss; Stockholms universitet; []

    Sammanfattning : The Hassan–Rosen bimetric theory is an extension of general relativity which considers the interaction between two metric fields defined on the same differentiable manifold. Self-accelerating cosmologies are exact solutions of this theory, and this makes it interesting to explore. LÄS MER
