What defines a black hole as being a black hole is it's event horizon. This is a sphere where time is thought to come to a stand-still. What occurs inside this sphere is impossible to determine as nothing that is inside ever gets out.(the radius of the sphere is called the Schwarzschild radius) > > To > > > give you something closer to home to see my point consider the earth. > > Time is operating at a slower pace at sea level than it is on the top > > of Mr Everest.

Precisely gravity is slowing time down. A sidelight I should have used the north and south poles in my presentation as these are the only points on the earth that reain still wth respect to each other and so leave the effects of Special relativity out of consideration. In actual fact Special relativity slows clocks down more on Mt. Everest compared to sea level than gravity slows time down at sea level with respect to Mt. Everest time. So the clock on Mt. Everest would be moving slower than sea level clocks. Antarctica -south pole is sufficiently higher above sea level compared to the north pole to see just the effect of gravity on time. > > In other words, may be the "needles" (in whatever form) are just > heavier and therefore move slower? needles? > > > Since I don't accept the reality of event horizons your fisrt > > question is off the mark and would be better posed to someone who > > believes they exist. > > To your second point the speed of light is taken to be 300,000 km > > per sec in the near perfect vacuum of space.

No matter which frame you measure the speed of light, no matter how much one second in one frame differs from one second in another in each and every frame light travels at the same speed-not just 300,000 km per sec in a vaccuum. Light travels at a different speed in each different medium. These speeds are constant in every frame as well. The speed of light is constant in all medium in all frames.

By the conservation of momentum law, anything a'falling at can fall out if the interaction has finite mass and entropy. Therefore, any body or wave can leave the EH as easily as it went in. > > Physics FAQ: Are There Any Good Books on Relativity Theory? > > http://math.ucr.edu/home/baez/physics/Administrivia/rel_booklist.html > > Time in different frames is slower or faster than in other frames. slower or swifter freer or faster Glue is fast; rockets are swift; birds are quick; pizza is speedy; motes are fleet. > In GR terms the Schwarzchild radius of any mass is like the speed of > light is to mass in SR terms. > The closer a mass gets to being inside it's Schwatzchild radius the its -Aut

At an 'event horizon' the rate of flow of time is zero. Time dilation is perspective dependent. If you don't know what that means, you certainly don't understand relativity. Black holes are "observed"--that is their "paw prints" are observed, as Neil deGrasse Tyson likes to say, all over the cosmos from invisible binary stars to Sag A* and galaxy after galaxy and quasars.
