Such stars have been observed to exist. The common thought is that they formed within galaxies but ejected from them through gravitational forces.
- floxy 6y agoAwesome. That's a great article: "...several other anisotropies at other wavelengths – including blue and x-ray – have been detected with other space telescopes and they are now collectively described as the diffuse extragalactic background radiation. Several explanations have been discussed by scientists, but in 2012, it was suggested and shown how for the first time this diffuse radiation might originate from intergalactic stars. If that is the case, they might collectively comprise as much mass as that found in the galaxies. A population of such magnitude was at one point thought to explain the photon underproduction crisis, and may explain a significant part of the dark matter problem."
