A slightly differently formatted version... not a pdf file:

Hope this helps.

Thank you so much. I've got it now

I am not convinced that I have not got it yet, but it is fun trying,.

@Jason R Carrico, Grinkle, et al:

Have a look at the following article by Charles Lineweaver and Tamara Davis. "Misconceptions about the Big Bang." This was published in the March 2005 edition of Scientific American. It deals fairly directly with most of what is being kicked about here.

Here is a link to a copy of the article:

Highly recommended.

That article makes it very easy to understand 'universal expansion'
thanks

in my not-so-humble opinion, if we could see a person looking thru a telescope in our direction, that person could not see us, but how our galaxy looked 13-14 billion years ago. since that person was alive at the 'beginning of the universe' the visible universe may have been that one galaxy. it wouldn't actually be the only galaxy, just the only one to shed enough light to see. light from other galaxies hasn't reached the viewer yet, so darkness in all directions would be seen.

Let's replace "person" with "observer", since we commonly use the latter term when discussing how things look in the universe. This observer would be constrained by the time it takes light to travel to their location, yes, but so would we. So this observer would have had to exist 13 billion years ago and would be long, loooong dead. They wouldn't have been able to see us, or rather our area of the universe, because at this time the light from our area of space had not yet had time to reach them.

since that person was alive at the 'beginning of the universe' the visible universe may have been that one galaxy. it wouldn't actually be the only galaxy, just the only one to shed enough light to see. light from other galaxies hasn't reached the viewer yet, so darkness in all directions would be seen.

Pretty much. At this time, the visible universe for this observer would have been a very small area of space that contained matter in the early stages of galaxy formation.
