if a black hole which has a finite mass can create a huge well or dimple in space/time,then ,if it is possable, how much mass would be needed to rip space/time?

Actually a black hole has no finite mass... the laws of physics break down at the even horizon thus we cannot clearly define what it is. I believe that black holes already do break the fabric of time/space, if you think about it all black holes' mass are equal to each other from our prospective.
Actually, the expansion of the universe is accelerating. This is being credited to dark energy, though there is not much known about it at this time. If the universe continues in this manner, it will produce what's known as "the Big Rip." What then happens is speculative and I haven't seen much extrapolations on the question. This is one of the areas that is occupying my mind at this time.
Let's see... Ripping the fabric of space time, I would guess, would probably take as much energy as began the universe. Although, I'm curious, what a giant electromagnet would do connected to something like a nuclear reactor?
How do we know that it is possible, even in principle, for any process that takes place in space-time, to rip space time?
Firstly lets clear up that little point of infinite. At any given moment a Black Hole has a finite mass. Its mass can and has been calculated.
However it remains to be infinite in its ability to consume more... for infinity.
The big rip does suggest that atomic structuring and bonding of elements will fail as expansion overtakes integrity.. or do we just get bigger....?
As Tom stated a blackhole is formed when a given mass/energy becomes so dense that the gravitational field is strong enough to keep light from escaping.

Its even theorised that micro black holes can be created even at low energies, provided that the energy is concerntrated enough so that the escape velocity of the gravitaional field is greater than the speed of light.

The mass can be finite but the math predicts that the density of these objects becomes infinite creating what's known as a "singularity".

As Mario stated, we can only speculate on what happens beyond the event horizon of a black hole, since we have no way of recovering any form of data from within this region.
But Stephen Hawking has a theory about how these objects can actually radiate energy back into space
Hawking radiation - Wikipedia, the free encyclopedia
Whether or not these objects actually rip the "fabric" of spacetime is open to speculation. Many scientists suggest that if the conditions are right a "wormhole" may be created which can short cut across distant space by tunnling a hole from one region of space to another, in a sense ripping through the fabric of space.

What exactly does the question mean?
As I understand black holes, they are a one-way street - you can get it, but you can't get out. (Well, then there's Hawking radiation, but let's not worry about that for the moment). Would "ripped" spacetime mean you can't get in or out?
Proud advocate of the ATM idea that 0.999... is equal to one.
...OH, Dear me,. We seem to have some confusion... and its not mine.
This subject is of the ripping apart of space time as the inflation of the Universe continues to accelerate.
The cold death of the Universe.. might be a accurate extrapolation of the future state of this universe.
... and then a discussion of Black Holes and singularity science.
As a point of fact we know of 'Hawking's leak' and accept that it may well be so. That this is not this subject..
Other than the view that the super massive mass black hole may not be forever locked up.
All its mass at some time distant might actually leak away... To 'prove' or 'disprove' is a mighty subject..
This idea that the ever observed acceleration of expansion might leed to the ultimate fail of nuclear bonding.
Seems a leap of faith rather unscientific for me.. I know of NO actual abidance of such is observed.
Hence I cling to the Finite but unbound school of thought.
and I repeat my well known protest of fact.. The term 'Worm Hole' is a work of fiction presented by the wishful thinking of
Fiction writers... and worms... Show me some science that allows such a fiction to be real and I will recant my view..
That has not happened yet.
