Can confirm, no traffic cones on AC decks. It would be considered “FOD” or “Foreign Object Debris.” Edit: Also can confirm that everyone who goes up in a US Navy aircraft brings a puke bag, even the experienced pilots. <a href="https://www.youtube.com/watch?v=beC8FvROWdQ&t=571">9:31</a>

My favorite thing about Project Hail Mary: The idea that the first human and alien to meet would probably both be total nerds and super stoked to learn about each other.

I gotta admit the first contact being a mutually positive experience for both parties Really did something for me

Grace (a scientist) meeting Rocky (an engineer) and doing their thing, being best friends, was better than a buddy cop movie.

I love Hank getting ragebaited by Grace's paper just like people in canon 😭

Fit's the character of Grace to be like "If I've got a self-balancing centrifuge, I'm gonna use the self-balancing to its fullest."

It’s kinda horrifying that in the book it’s implied that there were probably many other intelligent species out there but they weren’t technologically advanced enough to survive

I think Rocky had a surplus of fuel because they got the time calculation wrong because they didn't know about relativity.

So many movies forget that you cannot cry for someone unless you have laughed with them. This movie took that idea and RAN with it.

It is my understanding that when Grace mentioned that they "didn't understand radiation," they were specifically and exclusively talking about "ionizing radiation."<br>Obviously they understood visible light and infrared, since they knew their own star was dimming, were able to locate the problem source, detect a star that didn't have the problem, and make a physical model of the infrared petrova line.

in the book, they make it clear that 40 eridani is dying much slower than sol, so it makes sense that eridians would have more time to develop a ship with a method of returning home. also in the book they say that rocky has been in the tau ceti system floating around alone for 46 years before grace arrives 😢
