I didn’t see this mentioned in the thread - but is it correct to say there would be points in our galaxy where there is absolute darkness…you couldn’t even see your hand in front of your face? I’d assume so - but there have been tons of space pics from far reaches where is seems that light still travels.
I was about to ask nearly this very question. I’d assume that it would not be the case within our own galaxy, barring massive dust clouds, as you can see the Andromeda Galaxy with your naked eye, and that’s many times more distant than the most distant thing in the Milky Way.
My question is, is there anywhere in the universe, with a view unimpeded by dust clouds, where a human’s vision would nonetheless not detect anything using normal vision? I’d assume it’d have to be millions of light years away, if not billions, due to the brightness of large galaxies.
There are large voids where you wouldn’t be able to see anything without a very powerful telescope. For example, the Bootes Void.
It’s not that surprising, really. Most of the objects we see in the night sky with our naked eyes are within our own galaxy. If the other stars in the Milky Way vanished, leaving only the Solar System behind, Earth’s night sky would be very dark.
