My understanding is that black holes have such a strong gravity that they suck everything remotely close to them in and now since about 2001 scientists have learned that black holes can move or float thru space, if this is true could everything in space eventually end as part of a black hole?

Since the universe is infinate this is impossible

It depends on a lot of factors. I have learned that many people believe and can theoretically prove that the universe is not infinite, despite what many people think--though this is often debated. Hypothetically speaking, I don't think that the entire universe coud become part of or be sucked into a black hole. True, black hoes don't let anything escape them, even light, but those objects have to be close enough to the black hole in order to be sucked into it (right on the event horizon of the black hole, and that it pretty damn close.) I have never heard of black holes being able to move around space, but even if they had the ability to do that, I don't think that they could suck everything around them into it, new stars are created every day and once it sucks in a few of them, there will be more to take their place. So, in a nutshell, no I don't believe that it is possible for everything to become part of a black hole, or be sucked into it. I like your question, though. I hope I helped answer it.

A black hole is an object predicted by general relativity,[1] with a gravitational field so powerful that even electromagnetic radiation (including light itself) cannot escape its pull.[2]
A black hole is defined to be a region of space-time where escape to the outside universe is impossible. The outer boundary of this region is called the event horizon. Nothing can move from inside the event horizon to the outside, even briefly, due to the extreme gravitational field existing within the region. For the same reason, observers outside the event horizon cannot see any events which may be happening within the event horizon; thus any energy being radiated or events happening within the region are forever unable to be seen or detected from outside. Within the black hole is a singularity, an anomalous point in space-time where all matter is infinitely dense and is infinitely compressed into nothingness.

Yes, black holes migrate around the universe, just as galaxies do. Everything is in constant motion. So, in theory, black holes could suck everything up like unmanned vacuums. But what is unknown is whether black holes can attain a critical mass, and no longer be black holes, such as a full vacuum bag. Also, when two black holes meet, they may tear each other apart, or become one big one. Who knows?

Except for known huge black holes at the center of galaxies, they are much smaller than the average star and there don't seem to be a whole bunch of detectable ones floating around on their own. I wouldn't worry too much about it.

Yes, in the very very long term (trillions of years in the future), pretty much everything will be inside the Black Holes that are now in the centers of galaxies.

The Universe is now believed to be infinite in size. Black holes cannot, even in billions of years, pull everything in.

In the very long term (millions of times the time since the Big Bang), all ordinary matter will indeed be contained within black holes.

Black holes are phantoms don't worry about them!
