The universe is what...about 13.7 billion years old? Perhaps within a respective cycle this is but a drop in a bucket or a grain of sand on a beach of time relative to the duration of the cycle. Perhaps there are already existing black holes much, much larger than the one at the center of the Milky Way or any other galaxy we can see.
There are, but not the size of what you suggested earlier. Plus they are expected to give off radiation over time, reducing their mass and causing them to shrink, making it unlikely for them to ever join together in huge numbers to form one massive one of that scale. Plus black holes do not suck in objects like a vacuum cleaner, they act like any other object that gravitates does.

And how is it that you're such an expert on the nature of black holes?
I am not an expert, I merely know the basics from reading up on them and learning here on PF.
