Abstract: (submitter) This book serves two main purposes: firstly, it shows, in a simple way, how the possible existence of an extra-spatial dimension would affect the predictions of four-dimensional General Relativity, a model known as the Brane world; secondly, it explains, step-by-step, a new technique called Minimal Geometric Deformation

Unveiling the Universe: Einstein's Theories and Beyond A little over a hundred years ago, Albert Einstein revolutionized our understanding of gravity with his general theory of relativity. "According to Einstein's theory, gravity is not a force but emerges due to the geometry of the four-dimensional spacetime continuum, or spacetime for

The prediction is that, if the edges of black holes really do defy general relativity and are fuzzy, then a series of echoes should be released after an initial gravitational wave burst. That's because the team predicts the fuzziness surrounding a black hole will act kind of like a hall of mirrors, trapping some of the gravitational waves

We present qualitative arguments in favor of an extension of the theory of the gravitational interaction beyond that resulting from the Hilbert-Einstein action. To this end we consider a locally conformal invariant theory of gravity, discussed some thirty years ago by Mannheim and Kazanas. We discuss its exact solution of the static, spherically symmetric configurations and, based on these, we

These observations match Einstein's predictions of how gravity bends light around black holes, as described in his theory of General Relativity. The echoes of X-rays from the disk have specific 'colors' of light and as the X-rays travel around the black hole, their colors change slightly. Because the X-ray echoes have different colors and

It was 100 years ago this month that Einstein delivered four lectures to the Prussian Academy of Sciences in Berlin, which culminated in his discovery of the general theory of relativity. Einstein's determined pursuit of mathematical equations that describe how the force of gravity works remains one of the most influential scientific discoveries of all time. If you're planning a party -- a
