Contract space-time in front of the crafts, expand space-time behind them. How? Not sure.

If you understand how a U-shaped piece of paper with two points connected by a tunnel would work...

I'm not sure there's much more to the understanding.

That's how it's possible.

The physics inside a wormhole wouldn't be like that of the paper certainly.

After all, it's not paper and a tunnel. It's connecting two singularities in a way that gets rid of their infinite natures in a physically accurate way.

But it means you can't pass information through them. Because the information can never move faster than light and the space between these two black holes would.

At least that's what I take from EPR=EP

You are thinking of a warp drive. Wormhole is more like a tunnel thru spacetime.

I fold paper towels a lot when I'm cleaning, but it doesn't seem to help me jump forward to being done cleaning. Sad.

Basically, imagine the paper is the fabric of the universe. Now imagine it’s a box, instead of a flat paper. You fold it the exact same way, but because you need to fold the two-dimensional paper in one dimension higher (3D) than the physical medium of paper, you would need to fold the three-dimensional cube in one dimension higher (4D) than the physical medium of space.

Does that make sense?

Have you ever heard someone talk about how objects with mass warp the fabric of space-time? This has been demonstrated by people taking a bowling ball and placing it in the middle of a sheet being held at all 4 corners. The bowling ball bends or ‘warps’ the sheet (fabric) in a similar way that mass from planets, stars or black holes warp space around them.

Now imagine that something bends the fabric so much - almost like folding a towel in half - that a point on one end of the fabric comes in contact with a point on the far side of the fabric. Now you can virtually jump from one point in space to another point, covering what would normally be a great distance nearly instantly.

I’ve been drinking and that’s the best I can do 🤣✌️

Best explanation I’ve seen tbh

Though I don’t condone teaching tipsy, you might be an exception.

Here is a good explanation with a good picture: https://www.sciencefocus.com/space/what-is-a-wormhole/amp/

Unfortunately the picture shows our 3D universe as a 2D graphic folded on itself in 3D, then projected again as a 2D picture! So it could be confusing. But the movie Interstellar shows the best graphic of how a wormhole should and would work. If it exists.

If humans were to travel through the wormhole, we wouldn’t actually leave space and travel down the middle (like shown in the movie Contact) but along the surface — always touching that paper.

That’s how a black hole warps space. That takes such immense mass that it would be impossible to travel through that. A wormhole could only be traversed if space-time were more like Swiss cheese with natural holes and tunnels. And we could only (still) traverse the surface of that Swiss cheese, but we’d get to the other side very fast.
