Astronomers have discovered a super-fast star system that breaks current physics models

No one can explain those speeds.

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’s so difficult about that? Aren’t there several ways that such speeds can occur? Close encounter with a black hole or neutron star is one. Ejection from a globular cluster would be a second. And perhaps being kicked out by a supernova is a third. Being kicked out by a galaxy collision would be a fourth.

Or perhaps it was simply moving at that speed when it formed.

Rather nice would be if the speed was created by collision with a large mass of dark matter ;-)
