    A rather large point here.

    Very often it doesn't get to our eyes.

    This is because you asked about distant stars.

    As well as becoming weaker and weaker, the light that arrives from distant stars is redshifted, which means it becomes of lower and lower frequency by the time it reaches our eyes.

    If the stars are distant enough, the 'light' is of too low a frequency to be visible to our eyes.

    This is why the new James Webb telescope is configured to observe the frequencies and thus to see stars we cannot.

    Of course we could see them if they were close enougvh.
