... Gravitational waves interact only very weakly with matter. Therefore, we need very sensitive detectors and an effective data analysis method to dig out the signal from the noise. For this, we need an accurate model of the signals we want to find. They can be described by a handful of parameters: the ...

Microlensing - Caltech Astronomy
... Microlensing refers to the special case of GRAVITATIONAL LENSING where the multiple images produced are too close together on the sky to be observed as separate images. However, the lensing can still be detected because these multiple images appear as a single object of increased apparent brightness ...

General Relativity Einstein`s Theory of Gravity Paul Woodward
... He went on to generalize the concept of a straight line. Not a straight line in space, but a straight line in space-time. In Galileo’s world, and also in the world of special relativity, a straight line is the path followed by an object moving at a constant velocity and not acted upon by any force. ...
