Imagine that a rival astronomer proposes that your mysterious object is actually the mouth of a wormhole to another dimension. The rival astronomer calculates that the wormhole mouth would need to be 10^13 m in diameter and would last for around a thousand years.

Which one or more of the following observations would disprove the rival astronomer's theory?

Variability on a timescale of 100 seconds

A redshift of 10.3

A spectrum that rises to shorter wavelengths

Jets that are a mega-parsec in length
