There are many trillions upon trillions upon trillions of black holes. Many of them are massive like the one in the center of hour galaxy. However, because they are nearly impossible to see, many go unnoticed. There are also uncountable amounts of microscopic black holes floating all around you. They are so small they are undetectable, but there still there. So to answer your question, yes there are billions of black holes, except there are probably even more than billions out there and we don't even notice them.

Can a black hole be as big as a human?
Technically yes, realistically, probably not. The best measure of the size of a black hole is the size of the event horizon. That we know of, black holes fall into two general categories: stellar mass black holes and supermassive black holes. The diameter of the event horizon is directly proportional to the mass. Stellar mass black holes range in mass from about 3 to 30 times the mass of the sun, with diameters several miles to several tens of miles. Supermassive black holes are millions to billions times the mass of the sun and are millions to billions of miles across. A black hole with roughly the mass of Saturn would have an event horizon about as wide as an adult human is tall, but there is no known way for an object of that mass to become a black hole.
What is an intermediate black hole?
An intermediate-mass black hole is one that has a mass somewhere between 100 and a million solar masses, i.e., larger than the stellar black holes, but smaller than the supermassive black holes. It seems likely that such holes should exist, but the observational evidence is not yet very firm.An intermediate black hole is one whose mass is somewhere between that of a stellar black hole (a few times the mass of the Sun), and that of a supermassive, or galactic, black hole (millions or billions of times the mass of the Sun).
Can black holes dies?
Black holes do not die but they can evaporate.
What is the mass of the biggest black hole?
That depends. The smallest black holes known are generated by the collapse of massive stars, so the holes themselves tend to be rather massive--on the order of the mass of a star. Most galaxies contain black holes that mass hundreds of thousands to billions of times that of our sun. Sagittarius A, our Milky Way's black hole, is a little over four million solar masses. It is possible quantum black holes formed during the big bang. These would have been tiny singularities, with masses measured on the atomic scale. Stephen Hawking demonstrated fairly effectively such black holes would have preferentially absorbed charged particles from the quantum foam, bleeding mass until they evaporated. It is unlikely any would now be left from 13.7 billion years ago.
Why are black holes round?
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
Are there black holes by Jupiter?
no, the closest is billions of miles away.
How many black holes are in space?
billions upon billions space is neverending and we dont even no were thay are
How long do blackholes last in space?
That is a really good question, but no one actually knows. Though we do know that one day that Black holes will die because it will become smaller and smaller and then ping, it died. However the black holes that were create from the beginning of the Universe are still exist, so it will takes billions and billions and billions and billions of years from black hole to die.
Are black holes present only in the centers of galaxies or are they also present in intergalactic space?
No. There are estimated to be dozens or hundreds of black holes of various sizes in our galaxy, and billions in the universe as a whole.
Is a black hole just a hole in space that contains no matter?
No. Without matter there would be no black hole. The black holes confirmed to exist so far actually have a fairly large amount of matter (or mass) - at least 2-3 times the mass of our Sun. The largest black holes have millions or even billions of times the mass of our Sun.No. Without matter there would be no black hole.

What has the most gravity in the universe?
Perhaps the most massive of all "singular" objects in the universe is a super-massive black hole.Certainly a galaxy that has many black holes in it and billions and billions of stars has more mass and more gravity than any star or smaller galaxy. But as regards "point objects" in our uinverse. The most massive black holes, the so-called super-massive black holes, are the ones with the most gravity.
How does a black holes acquire greatest mass?
Most black holes are stellar mass black holes with masses comparable to those of large stars as they form from the collapse of massive stars. Scientists know of the existence of supermassive black holes that are millions to billions of times the mass of our sun and can be found in the centers of most galaxies. Scientists still do not know how these black holes become so massive.
Is there really black hole?
there is belived to be a black holes but is about billions of miles away, when a star exploxed it could go into a supernova and i am not sure about this but it may turn into a black hole.
How does a black hole have extreme mass?
Not all do - most black holes have masses comparable to that of a star; this makes sense, since they are believed to have formed from collapsing stars. There are, however, black holes that have thousands, millions, or even billions of times the mass of our Sun - called intermediate black holes, or (for about a million solar masses or more), supermassive black holes. It is currently unknown how exactly they got so massive.
When can you find the milky way?
You can find Planets, Billions of Stars, and Comets, meteoroids, comets, black holes and alot of other stuff.
How are supermassive black holes different from stellar mass black holes?
In their mass. a "stellar black hole" has a few solar masses (a few times the mass of our Sun), while a supermassive black hole (found in the center of most galaxies) typically has a mass of millions or billions times the mass of our Sun.
