The beginning was captivating, recognised a lot of concepts and mentally added to them. She lost me during the third theory. I didn’t have the scientific base for it and the descriptions got more complex and complicated.

Also didn’t love the overly sarcastic/self deprecating writing.

Informative, interesting, and—despite the fact the whole thing is about hypothetical events of the incomprehensibly distant future—occasionally genuinely moving (especially the Heat Death chapter, and the Epilogue). I also appreciated how upfront Mack was about the massive gaps in our knowledge of cosmology, and the extent of disagreement among experts in the field.

My only real complaint is that sometimes the book tried way too hard to be Entertainment. Stuff like Back To The Future references or jokey footnotes about the proper pluralization of "apocalypse" jarred like potholes between the science, which was what I really came here for. It felt as though Mack wasn't confident that subjects like the difficulty of measuring the universe's expansion rate would be able to hold my attention on their own. Thankfully this let up a bit as the book went on.

The End of Everything is a book for all of those who have an interest in cosmology and want to stay away from all the heavy mathematics topics. It's a fun, witty, informative, and really light read (If I had to compare it, I would say it follows the style of Cosmos by Carl Sagan).

Personally, I would have enjoyed it more had it been more math-heavy, but I also understand the purpose of Katie when writing this book and I am so happy with the results. Now I can recommend a science book to all my friends without having them sending me messages at 3 am because it's "giving them headaches".

This book was fascinating. It’s only two-hundred pages, but the author managed to explain such a vast area of physics, from quantum mechanics to astrophysics and cosmology. And she was able to strike the perfect balance between being accessible (not simple, but understandable) and not being overly simplistic or superficial. And she did it with a certain humorous tone to it that I absolutely adored.

This is a good introduction to cosmology and extrapolating the eventual fate of the Universe from the current understanding of the cosmological models. It provides a nice overview of the different theories and some of the scientists associated with them. It can be a bit heavy on terminology and jargon, and the final chapter or so felt a bit underwhelming.
