Cheers Larry :-)
Not yet, and I have quite a few series to complete before I explore the realm of dark matter. I will probably talk about it in the future when I write a cosmology series.
In the meantime, I noticed a post from @lemouth that just came out a few hours ago... I haven't looked at it yet, and it looks quite interesting. You could check it out. https://steemit.com/steemstem/@lemouth/dark-matter-versus-neutron-stars-round-1
Be well
Thanks for the advertisement (also in your post) :)
Thank you for sharing @muphy! I will be looking forward to those posts in the future.
