Well, look at it this way...
If there wasn't any black holes (or if black holes didn't have a massive gravitational pull), life as we know it probably wouldn't exist.
To me, black holes have no superior existence or importance. But they can be science and imagination. Science has still yet to answer many questions. But scientists and astronomers work hard to answer them. Black holes have been known for only sucking in things and never spitting them out. If one would survive a trip through the seemingly never ending black hole, they would almost certainly find a new era of space and intelligence for humans. It is almost impossible for a living thing to survive this trip. I would suggest an indestructible long distance camera or robot. Black holes can be used for great imagination skills. Such as books, movies, and TV shows. So, yes, black holes are seemingly unimportant, even to me. They can be an important, existing, inanimate object. I hope I helped =)!!!
Black holes are significant mostly because they have such a great mass that their gravity is strong enough that light (travelling at a speed in a vacuum of approximately 300,000 km/s) cannot escape (hence the name "black" hole. Since there is no light, absolutely nothing can be seen).
Answer
Even though black holes suck through parts of the universe, the universe is inevitably big, and growing so as the universe is being sucked into another dimension by black holes, it is also expanding.
Probably stellar mass black holes
No.
no dude, the evidences of the existence of black holes is now widely accepted and i believe that black holes rules our universe but it is difficult to find them because black holes are nearly the perfectly black bodies
Black Holes.
Answer
There are already black holes within the universe
Even though black holes suck through parts of the universe, the universe is inevitably big, and growing so as the universe is being sucked into another dimension by black holes, it is also expanding.
Black Holes' can 'eat' any type of matter in the Universe.
Probably stellar mass black holes
The universe likely contains millions upon millions of black holes.
Yes.
No.
The black holes may not devour everything since the outward velocity of the matter in the universe may escapethe gravitational pull of the black holes. Stephen Hawkins reckons that even the mass in the black holes would diminish over time, though over trillions and trillions of years.
No.
black holes are
