No. Black holes exist where gravity is so powerful that nothing can get out, not even light. "Dark Matter" is a vague hypothesis about the need for some additional mass that needs to exist in the galaxy in order to explain the way the galaxy does behave. We're not sure that "dark matter" exists at all.
What else can I help you with?
What if dark Matter is Time It Does not escape a black hole?
If all thing things pass through a worm hole. We have dark matter all over. How can it not past through a singletary. If you take all that we know about time. We always had a missing pieces. Ok, no more bull I believe that Dark Matter is Time . Matter flows into the center of a black hole and we know that nothing can escape. But we have too know that Dark Matter has too also have to go through the black hole. What if we look at Black Matter as a part /or time it self. We can't say that we know what Dark Matter is. We can't say what Time is. What if they were both the same. We know that they can not be Separated. I believe one day that it's from a Black Hole that we will see the Time distortion between Dark Matter and a Gravity Well. Remember Dark Matter is Matter. We can't see it right now. Just like Time. But who's to say there not the same.
What is the area beyond a black hole where black hole has stopped expanding and matter will no longer be pulled in?
There is no definite boundary for matter not being pulled toward a black hole. At large distances the effects of a black hole's gravity are not different from that of a different object of the same mass. How far out a black hole's gravity is dominant depends on that black hole's mass and its proximity to other massive objects.
What happens if antimatter gets sucked into a black hole?
Just the same as if normal matter falls in. The matter or antimatter will stay there, increasing the mass of the black hole (and making it more "hungry", i.e., making its gravity stronger).
How fast does light travel in one second inside a black hole?
Same as the speed of light. Darkness is only the absence of light, so when light leaves a specific "space" (at the speed of light) then the time it takes to be dark there will be equal to the time it takes the light to leave.
Why is the term black hole appropriate?
The term 'black hole' is particularly appropriate in its application to the astrophysical phenomenon of the same name due to the property of the escape velocity exceeding the speed of light. This means that no light or matter escapes a black hole.
Is a black hole known as a singularity?
No, they are not the same. A singularity would be inside a black hole.
How strong is dark matter?
Dark matter's strength is proportional to it's mass. This means that more dark matter in one spot is stronger then a little bit of dark matter in that same spot.
What is the complete absence of matter?
No, the absence of matter would be a vacuum, which is quite different from a black hole. A regular black hole has a fairly large amount of mass (which is basically the same as matter) in a small space.
What can a black hole do to you?
A black hole is one of the most destructive things in the universe. It grabs anything relatively close to it and takes it in, never to be seen again. They can destroy entire planets, galaxies, and more. However, without black holes, galaxies could not exist.
Why does a black hole have more gravity then the star it once was despite having the same or less matter?
This is a common cause of confusion. In a way, if no mass got lost in the creation of a black hole, then it will have exactly the same gravity than before. For example, if our Sun converted to a black hole (not that it is planning to do so...), our Earth would continue orbiting this black hole, in the same orbit as before. What makes a black hole different is that the mass is very concentrated; so, it is possible to get much closer to the black hole - and remember that gravity gets stronger at shorter distances.
What happens when a human gets sucked up into a black hole?
The same as when anything falls into a black hole: as it spirals into the event horizon, much of its matter is converted to radiaton, and the rest of it is absorbed by the black hole, adding to its mass. The fact is we don't really know. Theoretically, black holes are spatial singularities that lie at the bottom of a massive gravity well. The only thing that escapes a black hole is radiation, and we believe that is the result of the destruction of what falls in.
Does matter get erased by a black hole?
Currently, there is no evidence that it does exist, however, a lot of astronomers believe it does. A lot of astronomers have seen it but can't quite find any solid evidence that it does. To sum it up in a nutshell, it's basically innocent until proven guilty per se. ____________________________________ "Black matter" could be black paint. Perhaps you are referring to "dark matter"? There's a problem in the Milky Way; it doesn't fly apart. The Milky Way is rotating, and it is rotating so quickly - one rotation every 220 million years or so - that it would take a LOT of mass to generate enough gravity to keep it together. We can't see enough matter to hold the galaxy together! So either our fundamental theories of gravity are wrong - and they generally seem to work OK - or there is mass in the galaxy that we cannot see. If the mass were in the form of stars or nebulae, we would be able to see it. So the matter - if it exists - is "dark", and not easily detectable. Perhaps the supermassive black hole at the center of the galaxy is WAY bigger than we think. Perhaps there is some other force in the galaxy that we don't know about yet. And perhaps there is some kind of invisible, or indetectable, or "dark" matter. Or perhaps there s some sort of super-gravity that we don't know of yet, some sort of "dark energy". Or maybe it's just The Force, that Binds the Galaxy Together. Ever since Ugghhh the Caveman came down from the trees and started carrying a club, men have "made up" explanations for things that we didn't understand. This is where superstitions come from, and fables, and stories about the gods and heroes who climbed up into the heavens to shine down on us as constellations. So far, "dark matter" and "dark energy" are in that same realm; interesting concepts with precisely ZERO evidence. Keep an open mind; the reason why the galaxy isn't flying apart may be any of the explanations above, or all of them, or something else that we haven't thought about yet. I'll quote another science fiction character: Commander Data of Star Trek said "The beginning of wisdom is the ability to say 'I do not know'". Maybe it isn't fiction!
