When it's said that a star is 60 million light years far from the earth, what does it means? As far as I know, it means that if a beam leaves that star 60 million years ago, then now after this much time we can see it. Very cute!!! The nearest star to the earth is sun and we are observing its light with 8 minutes delay. So very naturally our time is different than sun or other stars.
This relativity of time is a nice rule in the nature. When we have our common arguments down in the earth, maybe there are some big bangs happening far from here, some stars are birthing and some are dying, some civilizations are growing or some are disappearing but optimistically we will hear about them 60 million years later, wowwwwww. We are so tiny in this world of physic rules…we are so far from finding other creatures of the world…

It was a interesting topic ;)
A light year is the distance that a photon would travel in one year or 9.4605284 × 10 to the power of 15 meters
Even thinking of other creatures livinig is sweet. During my childhood, I was always waiting for one of them to come in my room from the window. :)
So there may be a little prince somewhere, see. :)
