This is strange. I did not ask this question I clicked to view and answer, it then went from guest to the user name of mine.


The question I did ask was this




that question then posted as written by a guest user though the name of mine was on it in the beginning.


Very strange things in this forum happens sometimes.



Geno, your answer to this question is well much better than the one I might post.

Thank you Alan. I understand how that can be.


Let say the big bang happened near where Earth is. Then say the big bang blast the energy and matter out in to the universe as a sphere and say it moves at the speed of light for billions of years until it starts making stars and galaxies and still moves very fast while they are forming. Then it takes billions of years for the stars to make light and then the light travels for billions of years back to where the big bang happen.


So if the big bang happened near earth, and it takes 13 billions years to go out into space, and some billions of years to become stars and 13 billions of years for it to return the light to earth. This makes it seem the universe has to be 26 billions of years plus the billions of more years for the big bang energy to become stars.


If the big bang happen billions of light years from where Earth is now, it also seems the universe would be much more than the 15 billions of years. This would show the matter that made the Milkyway moved away from the big bang center as the matter that make the distant galaxies moved in a opposing direction.


This explains why the galaxies are 13 billions of light years distant after 6.5 billions of years, but not how the light have time to travel from a distant galaxies to the Milkyway and Earth, because this means 6.5 billions of years to go to where they are then 13 billions of years for the light to travel from there to here and that adds to 19.5 billions of years and that dose not count the billions of years for the stars to form.


I have not ask a question here but I explain why this is not easy for me to understand these concepts. The Hubble constant explain some of this, but it does not explain all of why this does not add up in a normal way. If you have more understanding of this or know a website that can explain more I would be appreciative. I have went to some sites on astrophysics but there are not many that much explain time of universe and distance from stars.
