  > Disk galaxies like the Milky Way form stars “inside-out” — starting from the center and working outwards through the disk. So, as a general rule, the farther out astronomers look, the younger the stars are.

Do they meant looking out from Earth (which is actually nearer to the center of a spiral arm than to either end) or out from the galactic bulge. Either way doesn't make sense.

Poorly phrased. The most recent stars are on the edges. The inner stars were first, hence the “working outwards”.

Looking from Earth at the stars closer to the center of a galaxy, they are found to be older. Looking from Earth at the stars closer to the edge of a galaxy, they are found to be younger.

When does "starting in the center" mean anything besides "starting in the center"?

The earth is not the center of the galaxy

He didn't say that. He said earth is nearer to the center of a spiral arm.
