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.
How are star dust gas and dark matter related?
There is no consensus on what dark matter or dark energy is so we cannot tell at this time.
