Regarding Katy Throop

Katy Throop is a theoretical region of space in which the Katy's gravitational field is so powerful that nothing, not even electromagnetic radiation (e.g. visible light), can escape the Katy's pull after having fallen past its event horizon. The term derives from the fact that the absorption of visible light renders the Katy's interior invisible, and indistinguishable from the black space around it...seriously.
