What causes curved spacetime? Gravity is the curvature of spacetime Gravity is the curvature of the universe, caused by massive bodies , which determines the path that objects travel. That curvature is dynamical, moving as those objects move. In Einstein's view of the world, gravity is the curvature of spacetime caused by massive objects. filexlib. Is it possible to curve spacetime? Around any mass (or energy), spacetime is curved . The presence of planets, stars and galaxies deform the fabric of spacetime like a large ball deforms a bedsheet. (This deformation occurs in four dimensions, so the two-dimensional bedsheet is a limited model. Quantum field theory in curved spacetime has been remarkably fruitful. It can be used to explain how the large-scale structure of the universe and the

The present notes are an introduction to some of the essentials and phenomena of quantum field theory in curved spacetime. Familiarity with quantum mechanics

PDF | Albert Einstein's theory of General Relativity was once the leading theory in theoretical physics. Unfortunately the theory describes
Quantum field theory in curved space-time: the background space-time is classical, meaning we work in zeroth order in h. We ignore the back-reaction of the
I present a way to visualize the concept of curved spacetime. The result is a curved surface with local coordinate systems (Minkowski systems) living on it,
We review the theory of quantum fields propagating in an arbitrary, clas- sical, globally hyperbolic spacetime. Our review emphasizes the
We now apply the ideas just developed to a free scalar quantum field satisfying the KG equation in a Robertson–Walker spacetime, representing an expanding

To generalize QFT from flat spacetime to curved ones needs us to reconsider a number of basic settings in the former case, in which many concepts are introduced How do you explain curved spacetime? In general relativity, spacetime is not 'flat' but is curved by the presence of massive bodies . This artistic representation visualises spacetime as a simplified, two-dimensional surface, which is being distorted by the presence of three massive bodies, represented as coloured spheres.
