It technically doesn't, given that a vacuum cleaner works via air pressure differences, and space is mostly a vacuum already. What it does do, is by an enormous amount of mass focused in a small point, create a very strong gravity field, to the point that even light cannot escape a certain proximity. This is known as the 'event horizon'. Basically, nothing we know of that crosses that line can escape the gravity, drawn into the singularity at the center.

Why can't a object falling in a vacuum ever reach terminal velocity?
There is no drag in a vacuum to act against the acceleration.
Are black holes balach?
i was doing this project for school. here was the info i found. black holes are black because no light can escape. because of that they are invisible. to see a black hole scientists use space telescopes and special tools to look at the stars. stars orbiting black holes act differently than other stars.
What is a black hole in the sky and how does it formed?
There exists variant theories for the existence of Black Holes; one hypothesis has Black Holes being created from the collapsed stellar core of larger than three solar masses, while another has black holes predating stars and forming upon the instance of the Big Bang. In fact, the concept of a star growing or shrinking has little to do with gravitational accretion. So if a Black Hole is just a converted state of stellar evolution, then should we expect that the Black Hole size should be dependent on the amount of material being attracted and annihilated upon its Event Horizon? Per the current consensus, there is not a relevant relationship between the observable size of the accumulated bulge about the Black Hole and the size of the Black Hole itself. And considering the Black Hole radiation jets act as the safety valve for the reactions within a Black Hole, one might speculate that, like a star, the size of the Black Hole has more to do with its internal reactions and less to do with the matter being converted upon its Event Horizon. Still another such theory has their formations predating galaxies and or even predating normal matter itself, existing unto the moment of the Big Bang itself (i.e. unfolding of SpaceTime into a traditional fourth dimensional condition).
Can a black hole be destroy?
I'm going to jump in and perhaps contiversially answer this one. Yes. They cannot be destroyed in the traditional sense, ie blown apart, melted, frozen or even annihilated with antimatter but they can 'die' and, indeed, must all eventually disappear. Black holes were once thought to emit nothing of any kind, hence the 'black' part of black holes but, recently, this has been proven false. To completely understand how, a little background on the vacuum of space is needed. Like the black hole, recent theories have changed how we look at the vacuum. It is no longer considered a void of nothingness, it is a sea of particles that spring into existence in negative and positive pairs, exist for a tiny fraction of a second, then annihilate one another. They are called virtual particles and, despite throwing the nature of the universe almost on its head (and just about breaking the first law of thermodynamics), they have been proven to exist and are now a part of mainstream quantum physics. Now, these particles exist as pairs of one positive energy particle, and one negative energy particle. They pop in, are attracted to each other, meet and annihiate. And everyone is happy; they could just about be ignored. But when they come into being near a black hole, it can grab the negative particle before it can destroy itself, pulling it into the event horizon from which there is no escape. The positive particle, counting its blessings and graduating from virtual particle to real particle, escapes the black hole as part of what we call Hawking radiation. And it gives the 'black' hole a healthy little glow. But the negative particle isn't so lucky. the process is extremely complitcated but, with its partner gone and its destruction inside the black hole inevitable, the negative particle also becomes 'real' in a sense. And that sense is its ability to act upon the universe, specifically the black hole. Though there is virtually nothing that can affect a black hole, except to make it larger, the negative energy particle can and it strikes the singularity, disappearing and taking a tiny amount of energy with it. In large black holes, this process is next to negligable. It would take far longer than the lifetime of the universe to destroy even a small black hole. But for the micro ones, this process can be much quicker, and if they can't find a constant stream of matter to replenish their lost energy they will quickly shrink and evaporate. Even in the large ones their fate is sealed; though it will take incredible peroids of time all black holes are destined to evaporate in this manner. That is why I said it was possible to destroy a black hole. The trick is not to attack it, but rather to ignore it. You cant kill a black hole by shoving stuff in, you'lll just make it larger and stronger. But you can destroy a black hole by starving it and, if it was possible to artificially produce these negative energy particles, they might be an effective weapon against an object that was, until recently, thought impervious. There is no known way to destroy a black hole. Stephen Hawking beleives that Black holes will "evaporate" over time, losing mass until there is not enough gravity to maintain the black hole.
Why would a computer reboot when any appliance like vacuum cleaner or dishwasher is turned on?
The electrical circuit voltage drops when an appliance is turned on. (Lights dim, etc.) A new circuit is needed or you could purchase a UPS (Uninterrupted Power Supply) to act as a buffer and prevent the voltage drop. JR
Can nuclear weapons kill a black hole?
No. A black hole is a dead star that slowly is gathering anything it can pull. A nuclear weapon would be expected to act on a regular set of rules and situation (surface of a planet.) A nuclear weapon can destroy things coming close to the black hole, but not the black hole itself. The whole reason a black hole is so strong is it is a star that fell into itself - folded inwards likes a moebius strip; launching missiles into the black hole would only 'feed it.' According to our present technology and science, you cannot destroy a black hole, they are already the most 'destroyed' you can be.
What is a black hole and how does it act?
A black hole is formed during a supernova (when a red giant star explodes)--the star collapses in on itself and creates a black hole. Then the black hole can move around or stay in one spot. They suck in everything around them (stars, planets, ect.) There is one black hole in the center of every galaxy. When two black holes come in contact, they create blue and red colors (one black hole is blue and one is red). If i remember correctly, they eventually become one, after circling around each other.

Why does ozone hole in antertca?
There is a ozone hole in Antarctica. It is because PSC's act as a base for reactions.

Why did jem act the way he did when he seen the knot hole being plugged?
he wanted to see a duck in the hole so he was mad about it
What is the Act of Commission?
Act of Commission is the doing of an act that causes harm. Example: I dug a hole in the road and you fell into it. I am liable because I dug the hole which caused you injury. Act of Omission is the failure to do something which failure causes harm. Example: I saw a hole in the road, I knew it was there, I failed to cover it up or failed to warn you about it and you fell in. I did not do what a prudent person would have done to keep someone from harm.

Why are tornados like giant vacuum cleaners?
The air pressure inside a tornado is very low. because the air pressure outside of the tornado is higher than the pressure inside, air rushes into the tornado. Rushing air causes the tornado to act like a vacuum cleaner; objects are pushed into the tornado.
