Black holes keep 'burping up' stars they destroyed years earlier, and astronomers don't know why::Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable 'burping' bouts. Half of all star-killing black holes may experience the same.

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?
