Ok. Permission to ask a mad question. Apologies in advance.

If black holes ‘suck’ everything in… could there be the equivalent of the ‘other side’ of one, that’s mysteriously ejecting a tonne of plasma?

Not saying that’s what this is, just prompted the thought.

Mathematically, it's possible, but scientists are still skeptical about whether or not they are real. They're called white holes and you can actually create a model of one in your kitchen sink. If you let the water just hit the bottom and spread out evenly in all directions, you can kind of visualize the way it's supposed to work. Action Lab on YouTube actually has a pretty good video about it which I suggest watching if you're interested. https://youtu.be/p3P4iKb24Ng?si=b3_RHuj0J3F_7DC1

Tangent, but you don't need to include the question mark or anything after in most urls. Definitely not YouTube links. It's just YouTube telling itself who shared the info (you) and they use that to track shit. But the link works just as well without it, and you're not voluntary spying on yourself.

Neat! I didn't know that. I just copied and pasted. Thanks for the info.
