White people doing anything good is actually bad. Duh. /s, but I think I'm accurately describing the viewpoint you're responding to.

It’s a description of a common Hollywood trope (or used to be), like the ‘magical negro’ [https://en.wikipedia.org/wiki/Magical_Negro].

Hard not to see once you know about them, and they are indeed common.

But what should replace it? Good Nuanced writing? Good luck with that!

> I guess it looks like it's down since it's a slice but the effect is an inward sphere? 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…

Other thing is I believe they say gravity is strongest at the center of the sphere/core but I would think the mass is split evenly away from the core eg. maybe 2/3 radius from the center where it's equal mass on each side. But probably doesn't make sense wouldn't be a ball.

Since the strength is represented by the slope of the sheet (not the depth), it should still line up. Underneath the ball at the very center the sheet will be level, to match as you say, that the field strength is 0 there. The exact shape will probably be wrong though since it's mostly determined by the shape of the bottom of the object.

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... Tangent I'll throw in here,…

I doubt my opinion will be well-received by all, but I hope that creators like the author of the Bobiverse will be able to, affordably and within their own capabilities, create new forms of content, such as AI-generated long-form content, like entire TV seasons, as the technology matures. That series is fantastic.

Very cool. On Voyager 2 we placed a map on the side of the probe that places the position of our sun based on an array of Pulsar stars (the map was designed by Carl Sagan). I noted in the PHM movie Rocky and Dr Grace made similar 3D maps (I think they were pulsars(?)). I guess pulsars form natural beacons that can be detected at large distances.

Pulsars also have a rotational period that provides a reference point for interpreting arithmetic notation.

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. Like, they only sent 3 people, 2 whom died on this UBER CRITICAL SAVE THE PLANET idea? And Ryan G…

Chinese film having 100% chinese cast = good.

American film having a single white male lead = not good.

In the vein of popcorn scifi, expeditionary force books are fun.

I'm at the point where if there's a computer display, or 3D model, or any asset in a movie, I want there to be a Kickstarter to pay the producers to open source the original assets. Even if it's a super restrictive license.

I want all of the War Games original graphics. I know people have come a long way. But I want all of them.

The "Hackers" movie. "Sneakers". "The Matrix". These individual assets deserve to be preserved! They're iconic. They're art, in their own rights!

For other software engineers thinking of following in Andy Weir's footsteps and writing a novel, I put together my guide to self-publishing using software tools and techniques here: https://frequal.com/forwriters/

Didn’t know he was a programmer!
