Barely made it through the first two chapters because the science part of this sci fi felt really implausible; the character interactions early in the third chapter were the last straw, convincing me not to waste more of my time.

I'm overall not super stringent about sci fi needing to be scientifically accurate, but I'd rather have an author just hand-wave away how things work and make up some jargon rather than name-drop real scientific concepts in a way that only makes their understanding look ridiculously shallow.

For example, at one point the characters were explicitly told that they'd switch to traveling at near-lightspeed once they left the Oort Cloud. But the far edge of the Oort Cloud is 3.2 lightyears from the Sun -- and their destination, Proxima Centauri, is only 4.6 lightyears from the Sun. So the characters were going to travel the first 70% of their journey at sublight speed (fun side note: we estimate that it'll take one of our Voyager probes 30,000 years to exit the Oort Cloud at its current speed), then switch to the fast speed for the final 1.4 lightyears.

Also, as other reviews have mentioned, the characters are supposedly late 20's/early 30's STEM majors -- at least three of whom either have doctorates or are working on them -- but they speak and act like YA protagonists. And, except for the abandoned spaceship, the characters seem to live in a world that's socially and even technologically identical to our 2024 -- they even mention watching TikTok -- despite the fact that it's supposedly 2061.
