I was mulling this over in my head and was wondering if someone could share some inlight into this for me. As we all know, a light year is how far you would travel if you traveled at the speed of light for a year. Now, lets say we have a star named x, and x was 430 million light years away from us here on earth. Does that mean that it has taken the light that star x produces 430 million years to reach us here on earth? and we are indeed getting a 430 million year old picture? Another thing that i was thinking about was about time dilation, as we increase speed, the amount of seconds in a minute becomes smaller. If we were to travel at the speed of light time stands still (please correct me if i am wrong), if so then when light travels from planet x to us here on earth does it not travel at a speed were time does not exist? So are we getting a current and up to date picture? What i am getting at is, are the photons that are being sent from planet x as new as they were when they were sent? or not? Thanks for all your help.
