Note the caveat at the end there: this result holds true for young galaxies.
According to the emerging theory, quasars are actually the cores of very young galaxies.
These dust lanes are usually seen in young galaxies with active star-forming regions.
If quasars inhabit young galaxies, theorists still must explain what generates their enormous energy.
Many of the smaller galaxies are very young galaxies.
Quasars are widely believed to be the cores of young galaxies.
These giant proto-stars will enrich the substance of the young galaxies here, with heavy elements.
One possible explanation was that younger galaxies contain more red giants than older galaxies.
The light is probably emitted by matter torn from young galaxies by the powerful gravity of a black hole.
We do have a chance, microscopic, yes, but finite, a chance of getting help in the young galaxy.
