Although I understand that the universe is approximately 12 billion light years wide, and that may mean that it took the light photons 12 billion years at 186,000 miles per second to reach the distance they did:
If you could travel at the speed of light for a time of 10 earth years, then, when you returned to the earth after 10 of its years, you have aged much less than 10 years. My question is, since a light year as it pertains to the light itself, is different or shorter than an earth year, if these comparisons can be concise and relevant? To us the universe seems to be 12 billion years old but to the photon or (if possible in theory) the human that traveled the 12 billion light years the universe would not be 12 billion years old but it would be much less. This seems to be a paradox to me.
For earth the universe is calculated to be 12 billion years old but for the light speed traveler it would seem to calculate a much younger universe. How do I reconcile this paradox Or is my assumptions wrong?
