This is question that has been on my mind for quite some time. As technology advances, telescopes are more and more powerful. This means that we can see further and further out. So if I look at an object (ie. a galaxy) with a powerful telescope don't I "intercept" the light earlier than I would with a less powerful telescope? By that I mean in a snapshot, don't I see a portion of the light emitted by the object viewed before it gets to Earth? Leading to another question (if the above is coorect): does this skew the estimation of the distance at which the object viewed lies? Or am I missing something (of which I have little doubt!) In writing this I am asking myself see the light before it gets to earth where your telescope is situated??? Hum!!
