A black hole appears black because not even light can escape the gravity of the hole. So it looks black, as there is no light coming off of it.

No. The idea of black holes being like vacuum cleaners is grossly inaccurate. A black hole is an object that has completely collapsed under the force of gravity. At large distances the gravity is no different from any other object of the same mass. At close range the gravity is much stronger and things start to get strange. The large mass in such a small area severely distorts space and time. Within a boundary called the event horizon the distortion becomes so great that the only paths forward in time go inward so nothing, not even light, can escape.
Gravitation? Yes black holes have enormous gravitation but it is not completely vacuum. When matter gets sucked into blackholes, noone knows where the matter ends up. Black holes originate from a really dense star collapsing on itself like a cookie crumbling if you crush it with enough force.
Technically, space is not a complete vacuum. There is always a very low-density amount of interstellar gas and dust. The idea of black holes being like 'vacuums in space' is a crude simplification created so that young children can have a basic concept of them. Black holes pull material in via gravity, not suction.
White blood cells engulf (eat) dead cells. They are like vacuum cleaners. :)
no. white holes are actually an object predicted by scientists to exist on the other side of a black hole. it is predicted to spit out objects that entered a black hole.
Black holes are an interesting phenomenon that astrophysicists would like to explore, but naturally, they would not want to get too close.
There are many places where one could purchase Sears vacuum cleaners. The best places to purchase Sears vacuum cleaners would be places like a Sears store or their website.
Yes they can.They suck almost every thing in the universe like a vacuum.
Typically, no. The vacuum cleaners have a tendency to want to just suck up the whole taco. They are greedy like that.
When it comes to vacuum cleaners, many people feel like they need to purchase brand name vacuum cleaners to get the results they want. However, this is not always the case. The reality is that you can find a number of great generic vacuum cleaners out there that perform at the same level of brand name cleaners. The only real difference is that you'll end up paying a fraction of the price with generic cleaners.
Hoover Steam vacuum cleaners come in a wide variety of colors, shapes and sizes! Because of this variety vacuums arent only available in black and white but often in colors like blue, red, silver, yellow, green and others.
Black holes are some of the strangest and most mysterious objects in the universe. Suction is caused by pulling something into a vacuum, which the massive magnitude like the tornados on earth.
Because they are both like a fat guy suck everything up and then dispose of it when their done. However fat guys don't give things back up as fast as tornados and vacuum cleaners

Black holes in science fiction movies are giant, black holes that rotate like a circular saws inwards.
vacuum cleaners were originally horse drawn
One can buy the best vacuum cleaners from retail or electronic stores like Best Buy, Future Shop, Target, Canadian Tire, Wal Mart, home depot, Super Store and many more.
