It can be summed up as "Ken Meets Jesus", "Ken Goes to Space", "Ken is a bumbling moron", "Ken's first friend". "Ken's White Savior moment" This appears to be the norm for US based scifi now. Glad I'm watching movies like The Wandering Earth and Alienoid instead. It had a good premise. But it also fell apart immediately.

Just FYI the sizes of the planets, stars, and their orbits are not to scale at all. To get an idea of how empty space is, there are 63,360 inches in a mile, and 63,239 astronomical units in a light-year. So if you scaled everything down such that Earth was 1 inch from the Sun, Neptune would be 30 inches away and Alpha Centauri would be 4 miles away. If you were using a 4k display and had the Sun and Alpha Centauri vi…
Also, I did a top-down pixel measurement, where I could see the distance to Tau Ceti as well as the orbit of Neptune. The radius of Neptune's orbit was 32px, while the distance to Tau Ceti was 1152px, for a ratio of 36, when in reality, Tau Ceti is 11.9 ly away, while Neptune has an orbit radius of 30 AU, which means Tau Ceti is around 25,000 Neptune orbits away, so the planet orbit scale is too big (or distance to other stars too small) by a factor of ~694 (25000/36)
Edit: Since this was top-down, the vertical displacement didn't factor into the distance, which also contributed to Tau Ceti appearing too close on screen, so the error is slightly better than that, maybe a factor of 600.
Edit 2: Tau Ceti is rendered at 3.652 pc × 3 world units/pc = 10.956 world units
Neptune’s orbit radius is rendered as 30.05 AU × 0.0065 world units/AU = 0.195325 world units
The rendered ratio is 10.956 / 0.195325 = 56.09 Neptune-orbit radii
The real ratio should be 25,067.5 Neptune-orbit radii
The scale error = 25,067.5 / 56.09 = 446.9×
I am so happy this movie did great, the book was great Similar to me books: Bobiverse, Long Way To A Small Angry Planet I'm not a heavy reader This site is cool, I want to get to know stellar navigation stuff for astrophotography watching a video like this where they pull up star charts to point the telescope at it pretty cool https://www.youtube.com/live/TexqPMQMyZg?si=oEnvrxW21-D0VXGV...

Yes, gravity is a vector field: every point in space near a heavy body has a vector pointed at the center of the body with a magnitude of the field strength. https://en.wikipedia.org/wiki/Gravitational_field
Whenever someone uses fabric sheet analogy, they need to shout that the X-Y of the sheet is a 2 dimensional analog of X-Y-Z space, and the Z direction of the sheet is the field magnitude, with the slope indicating direction.
All models are wrong, but some are useful (for understanding).

> White Savior moment ???
/s, but I think I'm accurately describing the viewpoint you're responding to.

That's a movie you watch while drinking, take a shot every time you see something absurd
this is cool. My nit pick- aren't the petrova lines curving along the wrong plane? For example, in our solar system the line should start at the sun and should be pointed at where Venus used to be, but then curve towards where Venus is now (until gets to venus). Since the astrophage will course-correct over their journey and stay in the same plane as Venus' orbit.
It has been a little while since I read the book, but I think you have the cause of the curve wrong. These things are moving at such a high percentage of the speed of light that there isn't much visible curve from the movement of the planet. The curve is instead caused by them leaving the star at the pole (which leads to a different nitpick of the visualization since the curve isn't shaped to represent that). It's th…
