For those not familiar with both terms cosmology explains how the cosmos works; astronomy deals with what we see in the universe, like planets and stars, and with the telescopes we use to see them.
I have posted some of my views on cosmology to a Facebook group named: Cosmology & Astrophysics. The exchange of posts followed by comments and replies in this format is a presentation similar to a debate.
This is too much content for one very long topic or for so many individual topics in this web site. This way the browser deals with it for the reader only when selected.
If you have a FaceBook account and wish to see more of the exchanges (including posts and comments by others) in this FB group, I post as 'David Michalets'
I have noticed that some older posts and comments have been purged over time so at some future date some items in the list below might be gone from the site (but these are also maintained here). I do not know the criteria as I was never informed at the time. Perhaps the FB group will close (I am not the only one frustrated the site admin does not remove inappropriate posts) and I will find another similar site.
Please click on the date link to see that day's text.
I consider the content below of more interest than the other comments I posted to that FB group but not copied below.
Here are my posts to that group shown with date in bold; the rest are my comments to others' posts; a brief topic is shown for each line
