1.5 million?
100,000 years is the much more commonly reported number.

Still though, should interpret my “probably” as more of a “maybe”, haha

It does apply, technically, but yeah the effect is too small to see with the naked eye

A few nearby galaxies are visible, most notably Andromeda, but still redshift isn’t naked eye visible for these

In reality, it’s probably already happened! And the light just hasn’t reached us yet
Pretty insane to think about that
