A white hole?
The Cat: So, what is it?
Kryten: I've never seen one before - no one has - but I'm guessing it's a white hole.
Rimmer: A white hole?
Kryten: Every action has an equal and opposite reaction. A black hole sucks time and matter out of the Universe; a white hole returns it.
Lister: So, that thing's spewing time...
Lister: [donning his fur-lined hat] ... back into the Universe?
Kryten: Precisely. That's why we're experiencing these curious time phenomena on board.

Lister: [minus the hat] So, that thing's spewing time...
Lister: [donning his fur-lined hat, again] ... back into the Universe?
Kryten: Precisely. That's why we're experiencing these curious time phenomena on board.
Lister: What time phenomena?
Kryten: Like just then, when time repeated itself.
The Cat: So, what is it?
[Kryten, Rimmer, and Lister stare at Cat]
The Cat: Only joking.
-Red Dwarf
So what is it?
A white hole is a theorized antithesis to a black hole. While a black hole sucks matter in and destroys it, a white hole seemingly creates new matter and sprays it into the universe.
Afaik, we haven't actually observed one before. It's just a mathematical theory. But black holes used to be nothing more than theory, too.
Edit: I haven't seen Red Dwarf in so long, I didn't realize you were referencing it. 🤣
So that thing is spewing time back in to the universe?
