Bests & Worsts Reviews from Amazon

For a space opera sci Fi novel, it seems the author has paid the absolute bare minimum of attention to how any of this actually works. To completely spoil the book because you should definitely not read it, the entire first third is all about this "dreadnought" converted research station at the edge of the universe. Something of a novel and intriguing concept, so I kept on reading past the sample. It's a shame how bad things got after that. This book is just one of those books that gets the science so glaringly wrong it's impossible not to have it break your immersion as it so frequently does for me. The first major thing that really bothers me is that multiple characters, including someone who quite regularly flies along "the divide" (the boundary to the matter-based universe and the dark matter one) is flat...... Flat? Flat?!?!? No! It isn't! And there's no reason to think it should be. Our physics is quite far from suspecting this but most modern theories believe the overall shape of the universe is probably a sphere too! Why would it be flat? How does that work? This brings up endless questions that the book doesn't even attempt to address. The main conflict for the beginning part of the story is that the universe *stops expanding*. Literally. The heat death of the universe BEGINS, and the characters have to somehow stop that. This is the central conflict of the book. Humans that seem way too far from advanced enough to reach the edge of the universe suddenly being present to watch the heat death of it begin. HOW DO YOU STOP THIS? How, would anyone resolve this conflict? How do you stop the heat death of the universe? I didn't find out because I refunded the book after several characters seem to equate "the edge of the universe" with "the edge of the Galaxy." Surely, if humanity is advanced enough to reach the literal edge of the universe they're so incredibly advanced that they could reach multiple galaxies. After all, we have found many other galaxies but still don't know where the edge of the universe is. This, logically speaking, would mean that multiple galaxies would be closer to us than the edge (if it even exists). But the characters for the entire first third of the book only seem to ever refer to the one. What???? Every time someone utters the phrase "in the Galaxy" internally I'm screaming and wondering if the author forgot the setting of her own book??? There are many many many galaxies in the universe. We have no idea exactly how many, but we do know they're there!
