I decided to post a new thread to distinguish from my other post
The paradox is as this: suppose that 10 billions years ago a guy was born ( let's call him "Universeguy"), in a place near the Earth (because obviously Earth doesn't exist yet), first, he was a lucky guy , he discover how to live eternally and he is alive now.
Second, he loves Astronomy, and one day turn up his eyes to the sky and saw a beautiful galaxy (lets call it "Pary galaxy"), that was just forming ,he was obsesed with it,and he look at the Pary Galaxy every day and every day he took a photo of it, first he could saw it easily with naked eyes but as the time pass over because of expanding Universe, he has to began to use telescopes more and more powerful, but still every day he tooks a photo of PG, during 10 billions years until our times.
As Mr Universeguy is live now, one day he attend a conference featured by a famous astronomer of our times, and discover surprisingly that this astronomer was precisely studying the PG, the astronomer shows a photo of the Galaxy and SAY THAT THE IMAGE OF THE GALAXY IS OF HOW IT LOOKED 10 BILLIONS YEARS AGO
Can you see the paradox? For "universeguy" an actual photo of the Galaxy is how it looks NOW, For the astronomer, an actual photo of the Galaxy is how it looked in the PAST,10 billion years ago
So, what could be happening here?
