Its mechanism doesn't stop. But to you, observing it from elsewhere, it appears
as if it has stopped.
Anything that keeps time appears to run slower when it's near a large mass.
The nearer it is to a large mass, the slower it appears to run.
It has been said, and it's technically correct, that your head is older than your
feet. Your feet are closer to the Earth's mass, so that part of you ages slower
than the part of you that's farther from theEarth's mass.
The "reason" is found in the theory of Relativity.
If you were to throw a clock into a black hole, the extreme gravitational pull would distort the perception of time on the clock. As the clock approaches the black hole's event horizon, time would appear to slow down for an observer outside the black hole. Eventually, the clock's information would be lost beyond the event horizon.
When a star of sufficient mass stops producing energy, it will collapse into a black hole.
Subjective time wouldn't seem to change as you fell into a black hole.. if you were able to survive a fall into a black hole while clutching a clock it would seem to run normally. However, to a distant observer, they would notice that clock seem to dim and redshift, with the clock itself slowing down and dragging to a halt as you approached the event horizon.
To wind up a 3-hole Gilbert clock, first locate the winding arbor keyholes on the clock face. Insert the winding key into each keyhole and turn it clockwise until you feel resistance, indicating that the clock spring is fully wound. Be careful not to overwind the clock, as this can damage the mechanism.
a black hole is your answer and it is because when a main sequenced star collects to much energy the gravity stops and forms a black hole
When a black hole spits something out, it is called a "black hole jet." This process occurs when matter falls into a black hole and is ejected back out in powerful streams of particles and energy. The exact mechanism behind this phenomenon is not fully understood, but it is believed to be related to the intense gravitational forces and magnetic fields near the black hole's event horizon.
As with most questions about black holes, there's not really a simple answer to that. In practice, if you dropped an actual clock (or any other material object) into a black hole, tidal forces would tear it apart long before it reached the event horizon, let alone the singularity. From the point of view of an outside observer (which is what I assume you're interested in), the clock would appear to be running slow before it was torn apart. If we imagine a magic clock with infinite tensile strength, it would appear to get slower and slower as it approached the event horizon, and would finally stop just as it reached the horizon.
When the star stops producing energy, there is no more radiation pressure to offset the gravitation. In this case (if the remaining mass of the star is big enough), it will collapse to a black hole.

One common term used is black hole evaporation. This relates to a mechanism wherein the black hole's mass is gradually lost through Hawking radiation; but the rate of loss is inversely proportional to the black hole's size and thus accelerates as it shrinks. At the moment it vanishes it is thought to do so with a burst of gamma radiation; the Fermi space telescope is intended to search for such gamma flashes.
In a black hole, time dilation becomes more extreme the closer you get to the center, known as the singularity. At the singularity, time dilation becomes infinite, meaning that time effectively stops for an outside observer. This occurs due to the massive gravitational pull of the black hole, warping space-time to such an extent that time ceases to flow as we understand it.
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.
