Particles and anti-particles differ only by charge (electricity). Their separation at an event horizon results in Hawking radiation (as I understand it). In that sense electricity does escape and black holes do dissipate.
And matter cannot be "infinately (sic) condensed." That claim makes no sense.
The big bang theory suggest that it can up to the threshold when everything in existance is packed so tightly, it explodes.
Think of it this way, the laws of physics allow for something called a white hole. We havent seen one, but they predict it did play a part in the creation of our universe.
White holes in essence, spit things out, where black holes suck things in and condense.
Now we know black holes collide and consume eachother, making an even larger black hole, we've seen this happen.
Eventually, in x years the entire universe is destined to be consumed by black holes, and those block holes will all combine to create one huge black hole.
Now some scientist think that this is the big bang, when that black hole reaches its threshold capacity, and starts spewing shit out.
Whatever the case, the whole big bang theory relies on matter being able to be compressed to as far as we are concerned, infinite, and there may not even be a number we can type out in a million years to represent this. And once it reaches that near infinite threshold, it explodes.
