Equal mass means equal gravitational pulls...so unless they collide they would just orbit each other. While no theory precludes it you have to figure that the chances of them colliding isn’t very likely at all.

Orbiting isn't special when objects have equal mass. Objects of unequal mass orbit each other too, and just like objects of equal mass, "unless they collide they would just orbit each other." Or, be so remote from each other that "orbit" doesn't happen.

I do agree with your "probability" aspect of merging equal masses, just because of the diverse range of object masses.

At any rate, the initial question just had to do with merging black holes, which presupposes collision, and I wanted to clarify that given a collision between two black holes, the relative masses don't prevent merger. I think the logic is that once two event horizons meet, merging is inevitable. Neither object can escape the other.

Equal mass means equal gravitational pulls.

Considering that each black hole is pulling in 'matter' as quick as it can, how likely is it that they have the 'same' mass ?

Going to the other end of the theoretical chalkboard, how can a HOLE have MASS ?

They would orbit until the event horizon of one
is reached.

The question is can a stable orbit be maintained?
As the “hole” continues to pull in mass the EH would
continue to grow thus eventually degrading any orbit?

Does this mean at some point there will be only two
black objects in this universe? And what happens
when there is only one??? Critical mass?? and big bang?

Makes you wonder what kind of energy is released when
two reach that point??

Question for scientific minds.
If you and your flashlight had no mass and you turned
it on would you be moving at light speed?

>> so unless they collide they would just orbit each other.

That supposes blacks holes translate in space and would couple despite the momentum of one or both. Are the gravitational properties of two proximate black holes known or theorized?
