sorry to disillusion you, but space cannot be related to as a “jelly”. this shows extreme 2 dimensional thinking. space is, just as @bill says, like air. it is full of stuff, and is 3d. there is an up, down, left right, up/left, up/right, down/left, own right, etc. the position is relative to you, and your state in the space around you, but it is sill the same as that on earth. theories are not generally based on fact. they are based on what we percieve to be fact. what we se is not always what is there, however. what appears to us to be a black hole, may in fact be a simple trick of observation. the fact that we think it is what we say it is, simply reminds me that we need to remember that the beginning of wisdom is to say “I do not know”

Personally, I’ve always thought that energy doesn’t exist either… It’s just kinda abstract. As a little kid I believed energy = something moves.

Maybe the universe, even empty space IS filled with something. I’ve always imagined empty space as a jelly; and a wave, for example a photon, as a disturbance in that jelly.

My question is it possible that light only travels a very long distance into a space curve that we cant see into but will eventually emerge out the same way it went in?

At the center of a black hole there is zero size and infinite density. The laws of physics are inadequate to describe these conditions, so the question of what kind of particles can exist there cannot be answered at this time.

We cannot accurately picture space-time curvature in more than two dimensions. That is the reason one or two dimensional representations are used. However, even though we cannot picture space-time curvature in three or more dimensions, there are mathematical representations that can accurately model it.

The event horizon of a black hole is a boundary surrounding the black hole. Inside this boundary space-time curves back in on itself, so that anything inside the boundary cannot escape, including light. So, space-time curvature inside the event horizon is not the same as that surrounding Earth and Moon. Also, black holes cannot “explode”.

Here is a very succinct statement from the LHC website. “According to the well-established properties of gravity, described by Einstein’s relativity, it is impossible for microscopic black holes to be produced at the LHC.”
The “black hole” image in the article is a computer simulation.

What exact particles exist in the black hole? It’s denser than quark-gluon plasma. What exactly is denser?

I’m still trying to figure out how exactly objects bend space. It’s all pretty simple in 1D universe but I can’t picture our 3D space being bent. Basically the object moves into the 4th dimension (like that orange ball moves down, into 2D), dragging the space around it?

So light goes inside a black hole and just goes round and round there. Is this space bending the same like for example the Moon circling Earth?

Can a black hole get ”unleashed”? Like there will be a big explosion pretty much like a big bang when it gets big enough?

There was some talking that the LHC can create a black hole. Bullpoop I say. Earth itself doesn’t have enough mass for a black hole, right?

Is that black hole image real?

Thank you for your time!

Even a neutron star has limits to how massive it can get, and somewhere above 4 or 5 times the mass of our Sun a neutron star’s gravity is so powerful that the star itself must collapse into a zero-dimensional singularity that we know as a Black Hole.
