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 (FB) 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 gets each 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' Access is probably limited if not a member of the group.
Perhaps the FB group will close and I will find another similar site, but I have this copy of my content. Eventually I tired of other’s many posts about wrong conclusions, even after I pointed out those mistakes.
On 04/18/2019, I switched my posting to FB group named: Cosmology. For the new group I revised several previous posts and posted the new version to that group; I also posted new content to this group. Some members in this group became rather hostile when I questioned a black hole.
On 04/23/2019, I switched my posting to the FB group named: Electric Universe theory. This group is receptive to discussing problems in cosmology. For my new content sometimes I also post a copy to that first FB group in an attempt to continue presenting new ideas though the two groups have a different history from me so some edits are needed.

I consider the content from my posts below of more interest than comments I added to posts by others in a FB group.
Here are my posts to that group shown with its date;my comments to others’ posts starting in 2018 (> 50) are on a separate page; a brief topic is shown for each line
