  1. Hello forum members! I read an article the other day concerning a cosmic event that took place 260 million light years away. The article also suggested that this particular event took place 260 million years ago. Even though I understand the concept that, for example, the light of the sun that we see right now is from ~8 minutes ago (given that the sun is 8 light minutes away from the earth), I felt that the article was not taking into consideration that the universe is expanding; and that the event may have occurred later, but only reached us now, given the compounding effect of the universe's expansion on the distance of that body from the earth. Would anyone care to weigh in on that and tell me if I'm completely off here? Could it be that the light from a cosmic event that is 260 million light years away may have occurred much later, but only reached us now because of the universe expansion effect? Thank you! PS - sorry, I don't have any physics background.
