it's a paint chip off a 150±15 yo. Baltimore building. I can count 37 layers with a toy microscope. Fun to speculate the color shift about halfway represents the end of coal as a residential fuel, but could just as well be fashon.

The crumples to the side are to remind us that lead never sleeps. They're not noticable to the naked eye.

Hypothetically, if a planet existed orbiting the sun in the same orbit as earth but directly opposite us so behind the sun. Would we know? How would we know? Has anyone ever checked?

Im in the early stages of working on a story focused on an observation station focused on studying humans and earth in general, but I'm want the station to be feasible in its ability to hide. My main questions are

1. How could it visibly hide itself? I've seen many people talk about black paint or "optical cloaking". While the first is obvious in how it works, I'm curious on how possible the second is or if there are any other options?
2. What would the best location be? I'd like the station to be as close to earth as possible, but I feel like directly orbiting the earth would make it very difficult to hide

Im mentally picturing observation posts from stellaris and I'd like the keep that vibe while making it far more scientifically accurate.

Im a physics major freshly into my junior year. Currently taking physics 2 and calc 3. Ive been thinking about my major more seriously lately and considering changing it because i really so want to be able to find a job with just a bachelors degree without having to go back for a masters.

At first I thought engineering was the best one to change to but tbh i dont actually want to do engineering in anything. I think i prefer something more analytical. More mental related than heavy hands on stuff.

But idk what stem degree I can switch too that wont be taken over by AI or atleast not entirely and is in high demand with just a bachelors.

I do want a masters degree but in something completely outside of stem.

For now im just trying to figure out the best major i can change to that will guarantee me a higher chance of getting a job after college with only a bachelor's degree.
