But how to limit the age of the black hole? How to determine the type of black hole, was it originated yesterday or 13 billion years ago?

Simple

Objects have mass the more mass they have the more gravity they have

Gravity warps space and time

Imagine a bowling ball on a trampoline, the weight of the ball has warped the trampoline. And objects near the bowling ball will be drawn towards it.

If you throw an object up it will fall back down, as you lack the strength to beat the gravitational pull of the earth.

To break free of the earth's gravitational pull you would need to acceleration the object to a speed of 11 meters per a second per a second.

Objects that are more massive or have that mass more condensed will have a greater escape velocity.

For example the Sun's escape velocity is 400 metres per second per a second.

Now a blackhole is so massive and dense that the escape velocity is greater than the speed of light which is 300,000 metres per a second.

And since nothing can travel faster, nothing can escape, not even light, hence why they are black.

A teaspoon full of black hole matter weighs many times as heavy as Mt. Everest. That is how massive and dense they are.
