Title: Death of a blackhole
Post by: ukmicky on 18/02/2008 22:05:10

We all know that stars can be ripped apart by the tidal forces of a black hole ,however could the same happen to a small blackhole.

Hypothetically if a small black hole was caught equally between two large equally massed black holes circling around a common centre what would be the effect on the small one if it drifted into the Common Centre  ,could the small BH be ripped apart if the gravitational forces between  the two large ones was strong enough.

Or is the mass of a black hole concentrated and squashed into such a small area that the forces holding it together will counteract all possible external forces acting on it. [:-\] [:)]

Small black holes are in fact tougher than large ones becuse the gravity gradient at the surface of the event horizon is larger than that of a large black hole so small black holes would produce effects on the event horizon of a large black hole and not vice versa.

ok so change it to two small one's attacking one big:)

As Ive detailed in the thread "Is a black hole a Point" the formation and destruction of Black hole like object is what forms stars, solar systems even galaxy's.

Mergers of two black holes will end up creating a single black hole. However, the total gravitational energy of this new hole will be significantly lower than the sum of those of the two individual BHs. The resulting outburst of high energy photons may be detected as a gamma-ray burst.
This is one of the most promising theories as to why we see GRBs.
