Theory Briefing
- Tabby's Star dims by up to 22% at irregular intervals — far too dramatic and uneven for a transiting planet alone.
- The dust cloud theory holds that uneven debris rings scatter starlight, but struggles to explain the longest dimming trends.
- A companion planet hypothesis suggests a gravitational partner could be shepherding obscuring material into the star's line of sight.
- The alien megastructure idea — a Dyson sphere under construction — remains on the table precisely because no natural explanation has fully won out.
