Artists' renderings of wormholes show two (very large) 3-D spaces, with bright event horizons, connected by a tube. Like this:

But, isn't that wrong? The singularity is at the geographic center of the "tube" - which actually isn't a tube at all. The black hole is acting more or less equally (disregarding quantum effects) on spacetime and matter in each radial direction in a sphere - right? So, wouldn't we actually see an event horizon and a swirl no matter where we looked? There is no tube, or perhaps even more accurately, there are an infinite number of straight tubes radiating in every possible direction from the singularity. Right?
(Forget about traveling through wormholes. The singularity's gravity went to all the trouble to capture you, it's not letting you go. It's a one-way trip.).

Artists have their imagination and show it in art. Art is not science. But it helps to popularize science to the public. But it is not science. Just pictures.
Can a tube be a singularity in the first place? It has at least one dimension while a singularity must be a dimensionless point, or else it is not a singularity. (Tell me if I'm wrong.)
I don't think that we ever can exploit wormholes. I'm not even sure that a wormhole in our macro world exist. In subatomic world, yes. But large wormholes? No, I don't think so.
Originally posted by FabianFnasI visualize spacetime like a matrix of lines very close to one another, a series of lines in X, another in Y, another in Z and then the whole thing evolving in time. So given a certain mass the lines will tend to converge on the mass from all three directions.

I think that would be a more accurate description of what happens from the incursion of a small mass where the lines all bend into each other towards the mass to what happens near a black hole where the lines themselves are stretched out towards the black hole kind of being pinched together and stretched into the 'insides' of the black hole.
I would love to get a graphic artist involved to actualize my visualization but know no graphic dudes or ladies.

But to have a tubelike black hole as one one-dimensional singular 'pont', well, in theory is one thing, but in reality, no. And this is what macro worm-holes is all about.
Show me one, and I will believe it.
Originally posted by FabianFnasEven the existence of black holes is so far just theory with a lot of supporting evidence. There was thought that the big accelerators would generate a small hole but that fell through, as it were🙂

What seems to be known is stuff floating around the black hole somehow ends up in a spinning disk shape around the 'equator' of the BH. Then stuff gets thrown out perpendicular to that disk.
That is of course all external effects of the hole itself, which would bear little physical relation to the disks and the energy leaving the 'poles'.
For sure there would not be a tube of bent spacetime just leading down the hole, it would surely be a full 3 dimensional effect like how you might visualize a whirlpool draining out a bathtub but that is basically a 2 D effect and what we would really see is if that 2D effect were spinning on all axes at once and all spacetime was warping around it in all directions including time.

And that energy is not leaving from within the event horizon, it's just a phenomenon starting at the outside.
"you might visualize a whirlpool draining out a bathtub but that is basically a 2 D effect"
This is easy to visualize, and this is supported from Hollywood and artists visualization. It has nothing to do with reality. I visual a black hole in 3D, and this doesn't come from Hollywood.
But I cannot visualize a black hole in the shape of a tube in the macro world. It would collapse instantaneously. And I cannot even less that any material object can travle unaffected through it to another place in Universe. No, that I cannot. And therefore I don't believe in macro worm holes.
In the quantum world, it's another matter...
Originally posted by FabianFnasWell, the worm hole thing presupposes the existence of 'negative matter' or negative energy which is what allegedly supports the tube shape. Of course all this is just supposition till one is actually built. I give it a thousand years of constant scientific development before it would be done though.
