**Disputed** Answers **1** questionPublished0

## Where it stands

**Disputed** None pieces of evidence for, three against. It needs two reviews to be accepted.

## What it predicts

- Large opaque structures give dips with the same depth at all wavelengths.
- Waste heat appears as infrared excess.
- Possibly radio or optical emission.

## What would rule it out

- Strongly chromatic dips together with no infrared excess and no technosignatures.

## Evidence none for · 3 against

[No optical laser signals were detected.](https://mysteriesdept.com/mysteries/tabbys-star/evidence/EVD0D8E7BKM2CZ5/no-optical-laser-signals-were-detected)

[The 2017 dips were chromatic, which large opaque structures would not produce.](https://mysteriesdept.com/mysteries/tabbys-star/evidence/EVD0D8E7B4010M5/the-2017-dips-were-chromatic-which-large-opaque-structures)
