## Where it stands

**Disputed** Two pieces of evidence for, three against. It needs two reviews to be accepted.

## What it predicts

- The body is a thin sheet; future analogues include objects with no natural explanation.
- Technosignatures may be detectable from such objects.

## What would rule it out

- A confirmed natural mechanism for the acceleration in an 'Oumuamua-like object.
