DIRECT OBSERVATION OF GRAVITATIONAL WAVES DIRECT
... nothing in this law that describes how the effects of gravity are transmitted from one place to another. In fact, according to this law, if we move one of the masses to a different point in space, then the other mass “knows” this instantly, and it reacts accordingly. This ability of gravity to a ...

Cosmic Hide and Seek: the Search for the Missing Mass
... gravity. We still see the effects of that force when we see red-shifted galaxies. Clumping. One of the problems with the Big Bang theory is its failure to explain how stars and galaxies could form in a young universe that was evenly distributed in all directions. What started the clumping? In a smoo ...

An introduction to the mechanics of black holes
... the behavior of solutions of hyperbolic PDE’s outside D + (Σ) is not determined by initial data on Σ. If no causal curves have past end-points, then the behavior of solutions inside D + (Σ) is entirely determined in terms of data on Σ. The past domain of dependence D − (Σ) is defined similarly. A Ca ...

Einstein`s Theory of Gravity

In other words, the presence of the gravitational field forces the space to be curved, i.e. there is a direct link between the presence of a gravitational field and the geometry of the space. 3.

SPACETIME SINGULARITIES: The STORY of BLACK HOLES
... to this curvature, the attraction caused by this singularity becomes irresistible - nothing can escape if it is too close. In essence, this tendency for the spacetime curvature to feed on itself and become infinite is why a black hole can form. Obviously this process will not work if we only start o ...
