A Mysterious Object Punched A Hole In Our Galaxy. What Is It?

An interesting mystery.

Doubting it is "dark matter" . . . unless it clumped together in a theoretical Black Hole or a theoretical White Hole. Only thing not mentioned was aliens . . . so just for fun am including that as a topic too, under "conspiracy theories" since UAP and UFO are not listed!

Seems strange that so many science videos, lately, are presented by folks speaking The Queen's English, lol.
