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.
