The NEW PHYSICS of Black Hole Star Capture | Extreme Tidal Disruption Events

If you track the motion of individual stars in the ultra-dense star cluster at the very center of the Milky Way you’ll see that they swing in sharp orbits around some vast but invisible mass—that’s the Sagittarius A* supermassive black hole. These are perilous orbits, and sometimes a star wanders just a little too close to that lurking monster, leading to its utter destruction in the spectacular phenomenon known as a tidal disruption event. We’ve never seen a TDE in the Milky Way, but we’ve seen them in distant galaxies—and we now know how to spot stellar destructions so extreme that they reveal properties of the black hole itself.

If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple theories that claim to do this, but it’s notoriously difficult to test them. They seem to require absurd experiments like a particle collider the size of a galaxy. Or we could try to physics smarter, instead of physicsing harder. Let’s talk about some ideas for quantum gravity experiments that can be done on a non-galaxy-sized lab bench, and in some cases already have been done.

The primary characteristic that defines black holes is in the name. Black holes are black. The gravitational pull at the event horizon is so powerful that not even light can escape. In this case, black means absence of light. We also think of black as indicating absence of colour. But it turns out there is a way to make a coloured black hole—as long as by colour you mean quantum chromodynamic charge.
