Re: Astrology and the Visible Stars — A Look Back in Time?
One curious question :
I find that astronomers discovering newer stars / galaxies which they state to be almost from the begining period of universe i.e. the light reaching us is almost from the initial era of universe.
How does it happen ? Does it mean the relative speed of our galaxy and the other one is faster than light ? Even if we are diametrically opposite to big bang centre, this looks weird.
Say the distance measured is 45 billion light years. How do we know that the light reaching us today is 45 billion years old. It should be much younger. The time taken by light to reach us was also the time taken by the other galaxy to move further away.
How come after such long time after big bang, we can still find the light from initial era ?
Some confusion in my mind.
Love and best wishes:hug:
