If they bend light the same way how will they tell the difference?

We throw a marble in.

If it gets crushed, it's a black hole. If it pops out on the other side, it's a wormhole 🙂

How do you know where is the other side?

Article says not quite the same. 3 mirrors of objects behind, rather than 4 when lensed by a black hole.

From the article:

> Liu also noted that wormholes would magnify objects differently than black holes do, meaning scientists could distinguish the two. For example, microlensing via a black hole is known to produce four mirror images of the object behind it. Microlensing via a wormhole, on the other hand, would produce three images: two dim ones, and one very bright one, the authors' simulations showed.

Well. The new galaxy finds from JWST have an explanation then.

Neither black holes nor wormholes bend light. They bend the spacetime that light travels through. When you look at images of a black hole the space is physically bent so much you can see the other side. Also black holes aren't actually 3D spheres.

This is all theoretical, of course. Remember that guys, before you start condemning it. Just sayin. 🤷

Why does anyone insist on believing in worm holes? Like we're really living in some silly space exploration game? You fly a spacecraft into a cosmic lens like that and it gets crushed down to the size of an atom and everyone dies a gruesome death. I'm sorry I love space, but it's just not a convenient place.

You very clearly don’t know anything about wormholes.

And what, you happen to know that you could fly a spaceship through one and end up in the Delta Quadrant safe and sound?
