Astronomers Have Discovered a Super-Fast Star System That Seems to Break Current Physics Models

Thousands of light-years away, on the outskirts of the Milky Way, astronomers have detected something no one’s ever seen before – a binary star (two stars orbiting a common centre of mass) that’s moving so fast, it’s clocked speeds that almost rival the escape velocity of our galaxy.

 

What does that mean? Something must be helping this star system gather such incredible momentum, and until now, the best explanation we had for hyper-velocity stars is that they were being propelled by the supermassive black holes that lurk in the centre of a galaxy. But here’s the thing: this binary star is nowhere near a supermassive black hole.

 

 

 

 

 

Anyone here got any ideas what could be doing this? Or is there some thing wrong with the understanding of physics

This article has a bit more about it, suggesting an external origin.

This was my very first thought, and was covered in the article:

 

Instead, the team hypothesises that either a crapload of dark matter must be surrounding the star like a kind of halo to keep it stable at such incredible speeds at the edge of the galaxy, or PB3877 could be an intergalactic intruder, formed in a neighbouring galaxy before infiltrating ours.

The article says that they determined that it didn't start near the center of our own galaxy. The article then extrapolates this to mean that it did not originate near a supermassive black hole, even though this does not appear to be something that was said, and seems plainly wrong. It could have been flung out of another galaxy by a supermassive black hole there and merely been caught by the Milky Way.

 

I'm sure there are other possibilities as well, but there is at least one right there that doesn't break any established physics.
