If black holes exist, and they suck up everything around them, they would soon suck in evething in the cosmos, and there would be nothing left, including the black hole it's self!!! And another thing, the warping of space can not be. Put four dots on a pice of paper, then fold it so the two furthest dots touch, everything in between them would collide!! Bye bye world.

A black hole does not mean infinite gravity. Actually a black hole has less mass than a galaxy, sometimes it has the mass of our sun, sometimes many thousand time that but it is never infinite. You don`t see galaxies sucking up all matter around them yet they are much more massive than black holes.
What differentiate a black hole with the mass of our sun from our sun is the density or the volume it takes. But if you were 1 light year away, this density has no bearing on you, and the gravity field is the same. It is only when you get very close to the black hole that things get extreme.
As for the four dots, you give one example where you fold the paper. Note that this introduces a singularity at the fold: the curvature of spacetime would not be continuous at that point. A much easier way to get the two dots to touch each other is the gently bend the paper in a regular tear drop shape.

OK fur brains, I can see that many of you have not read anything written by Stephen Hawking in like the past 5 years. This gentleman as well as Einstein, Newton, and others have generated huge amounts of theoretical, and I might say enormously complex formulae which dispel any doubt that blackholes exist.
However, this is not why I found this Q interesting, you are hitting on a concept that is starting to take shape in the astrophysical sciences- that black holes may indeed be ejecting energy onto a fabric of S-T that cannot be directly observed. Think of a drain- the water does flow into it, where does the water go? Hmmm- and another concept that is starting to take shape is that Blackholes also eventually collapse or discontinue- something that was not thought possible.
Ciao!

The length of the observable Universe is about 49 billion light years. Of this whole bit, 5 percent is inhabited by stars, very few of these are supermassive stars able to make a blackhole at the moment of decay. Blackholes are not consistant enough to have the gravity to reach everything in the Universe. They are spread very sparce. Their gravity wears off has objects are further away from them. Another thing, black holes do bend space but are not common enough to bend space near every where. Also, blackholes are also bodies that emit things such has gamma rays and radiation that we can detect, some of these are places where their is no other celestial body and so, no other solution. Plus, we are currently observing objects that are in the process of being consumed by blackholes. I am sure that that is a concrete proof. I suggest that you research a little more before you go against every astronomer, professor, scientist and expert in the world.
Conclusion: Blackholes are their, but they are not common enough to pull in everything in the Universe.

If the sun turned into a black hole, we would just stay in the same orbit we're in. The gravity doesn't get infinite. It doesn't swallow everything like a vacuum cleaner. Also, there was an experiment conducted in the early 20th century that showed that during an eclipse of the sun, star light was bent by the warping of space.

I can't believe in then either.
You are right ,if a black hole could exist, it would eventually accrete all the matter in the universe and sit there doing nothing for eternity.
The black hole is a theoretical entity that seems to be extremely logical.
Many prominent scientists believe in them but they are wrong.
It can't survive real objective analysis.
We live in a finite universe where a black hole would be a useless entity.
I can mount some very compelling arguments against them,which I won't go into here but you are right.
Good thought!

Black holes do not suck up everything around them and space is not curved so much that two different places touch. Both those ideas are gross distortions of the actual science as incorrectly reported by the popular press and repeated endlessly in places like this forum by people who have no idea what they are talking about.

First of all, the universe is ....
BIG ............ REALLY BIG!!!!
so black holes will need a LONG time to swallow everything. Also, while their gravitational strength is incredibly large, the influence of that force is relatively limited.
As far as the warping of space is concerned, your logic falls apart when projecting the universe in more than three or four dimensions. The warping doesn't occur in the x, y, or z plane, it warps in another dimension altogether.
You really need advanced math to help understand.

Although the gravitational influence of Black Holes at very small distances can be enormous, they still follow the Laws of Gravitation...Far enough from the Black Hole, the pull from it is negligible...
The basic misconception some people have is that Black Holes are these big Cosmic Vacuum Cleaners that will eventually absorb the entire Universe...While it is true that matter that drifts close to one is subject to its huge gravitational influence, the Universe isn't going to be sucked down into one any time soon...

Have you ever heard of the event horizan? That is the farthest point where everything gets sucked in. Everything beyond that doesn't get drawn into tha black hole.
Try rolling the paper into a tube instead of a flat surface and see if everything collides.

Hehehe. The fact is that 'reality' doesn't really give a rasty rats αss about what you believe. And there is all manner of observational evidence to show that black holes actually do exist.
As for bending of space, that's also been experimentally verified thousands of times.
If you want to have 'belief' being more important than 'reality' or 'observation' or 'measurement', perhaps you should consider a major in Theology?
HTH ☺
