DISCOVERING THE LIGHT OF LIFE
... light. • "You are the light of the world. A city on a hill cannot be hidden. Neither do people light a lamp and put it under a bowl. Instead they put it on its stand, and it gives light to everyone in the house. In the same way, let your light shine before men, that they may see your good deeds and ...

... 3C 273 is clearly a very luminous object indeed. Its light output corresponds to 1014 times that of the Sun. Most quasars do not radiate substantially in the radio part of the electromagnetic spectrum, and are called radio quiet quasars. A small fraction, of which 3C 273 is a member, do, however. Th ...

... According to GR, mass tells space-time how to curve, and the curvature of space-time (gravity) tells mass how to accelerate. The Sun, having a certain mass within a certain volume, will cause space-time to warp. This is why the positions of the stars near the edge of the Sun are different during a ...
