Hello and welcome! My name is Anton and in this video, we will talk about an interesting case of a missing ultra massive black hole in the middle of a very well known galaxy.

What happens when matter can’t get any denser yet somehow does? The answer — it becomes “strange.” Strange Stars may be the most massive stellar remnant that is just shy of forming a black hole. And they could be even cooler than black holes.

Normal maps are useless inside black holes. At the event horizon — the ultimate point of no return as you approach a black hole — time and space themselves change their character. We need new coordinate systems to trace paths into the black hole interior. But the maps we draw using those coordinates reveal something unexpected — they don’t simply end inside the black hole, but continue beyond. In these maps, black holes become wormholes, and new universes lie on the other side.

What if there was a museum that contained every type of life form in the universe? This experience takes you on a tour through the possible forms alien life might take, from the eerily familiar to the utterly exotic, ranging from the inside of the Earth to the most hostile corners of the universe.

New research is upending our idea of life and where it could be hiding: not just on Earth-like planets, where beings could mimic what our planet has produced, but in far flung places like the hearts of dead stars and the rings of gas giant planets. Nowhere in the universe is off limits.

Only when we know what else is out there will we truly know ourselves. This thought experiment will give us a glimpse into what could be out there, how we might find it, and just how far nature’s imagination might stretch.

Big thanks to Protocol Labs for their continued support of this series: protocol.ai.
