with how light works and the constant expansion of what we term the “observable universe” why don’t we constantly see new stars appearing in the night sky as the observable part expands and stars/galaxies light reaches us for the first time?
The night sky has stayed relatively the same (accounting for changing postions over time, stella phenom, supernovas etc.) for all of humans written history.

I have so many questions after reading the comments/answers!… (I’m a layman.) How can objects at the edge of the universe be expanding faster than the speed of light if as an object approaches the speed of light its mass increases exponentially? Are some objects actually becoming massive, or can they not exceed the speed of light bc of this? Or is “massive” just a relative term within e=mc^2 and their actual mass isn’t really increasing? And if things are getting more massive, will they start attracting each other more causing the universe expansion to slow and eventually reverse and contract, or is that not possible bc now the objects are too far from each other for gravity to matter much? And if there’s no true center and every object is at its own center of the universe, then aren’t there infinite “edges of the universe” in which case, which objects are passing the speed or light, or are we all passing the speed of light just relative to some objects (really distant ones) and not others (really close ones). Lastly, since we’re all at our own relative center of the universe, can we really not extrapolate to know what is the true center where the Big Bang originally happened?
