Hello, sorry to bother you, I have a question. The closing chapter of your book “brings it all together.” That was 2022; it is now 2025. Anything new you would add to that last chapter? If so, have you/are you writing an addendum? Or have a very recent book to recommend? Thanks in advance. Cheers.

Hello. I've just had the chance to read your book, and loved it. Although not a scientist myself, I do have a huge interest in and lots of books about astronomy, astrophysics and cosmology. Yours is now one of my favorites. Glad I can tell you that. Best wishes!

I'm still around, waiting for you to answer that question. And for Betelgeuse to explode...

Wish all photos were taken like yours. But just learned it's not the case. Please help make this known. It's a horrible world indeed. www.instagram.com/reel/C1q4Z4A...
