Huge black hole losing gravity ?

[Hiker]

Could a black hole be so big that even gravity could not escape ? Why not ? And if it happends, let's say when 2 huge black holes merge ?

1) When small black holes merge I suppose some of the very dense staff in between is in a "weak" gravity field (both huge gravity fields get substracted from each other when they spin arroun to merge), so it probably inflates toward more traditional material, so a sort of explosion probably partly responsible for the enrgy fields the melting send away.

2) If the melting result get suddenly a critical mass that even gravity could not escape we may have an external layer exploding or folding on itself because not attracted by the center anymore! And many other strange phenomenons, by definition It could not grow bigger, because anything coliding would push the equivakent mass outside, passing the no gravity layer and exploding back to something more like standard matterial so the outer layer of the huge black hole could process this transformation in a way allowing the exedent mass of the original black hole coliision to explose back visibly into space, plasma again, we may have a new big bang from a huge black hole!

What causes matter to fall into a black hole? Gravity, so you're asking if gravity can escape gravity..

Merging black holes just makes a larger one, more mass means more gravity.

Yeah, I was wondering why the gravities of 2 black holes would cancel each other out

Gravity does not ``cancel out''. Never.

The only way to ``remove'' gravity is to find something with negative mass.

Gravity is a field. This field, like the electromagnetic field, the Higgs field, and others, permeates all of space.

Gravity will always be able to ``escape'' from a black hole, just like the electric field will always be able to ``escape'' if the black hole is charged, and the magnetic field will always be able to ``escape'' if the black hole is charged (or has charge separation) and is spinning.

Now gravitational waves might not be able to escape, just like electromagnetic waves can't escape.

But the constant force component of any field will always be able to escape.
