The idea being implied was that light could actually be slowed by a strong enough force of gravity. ... This field would be so strong around and within a black hole that not even light could escape. ... The mass is measured by observing the speed with which stars and gas orbit around the center of the galaxy: the faster the orbital speeds, the stronger the gravitational force required to hold the stars and gas in their orbits (internet 1). ... In fact, researchers were able to measure the velocity within less than half a light-year of the center of the galaxy. ... The second discovery that sp...

Moreover, the intense gravitational field of the black hole prevents any light or other electromagnetic radiation from escaping. ... The Cauchy horizon is a light-like surface which is the boundary of the domain of validity of the Cauchy problem. ... The most defining quality of a black hole is its emission of gravitational waves so strong they can cause light to bend toward it. ... Propagating at (or near) the speed of light, gravitational waves do not through space-time as such -- the fabric of space-time itself is oscillating. ... When the star is passed on into the event horizon t...

Moreover, the intense gravitational field of the black hole prevents any light or other electromagnetic radiation from escaping. ... The Cauchy horizon is a light-like surface, which is the boundary of the domain of validity of the Cauchy problem. ... When the star is passed on into the event horizon the light that the star endures is bent within the current and therefore cannot be seen in space. ...
