    Beyond what’s been said already, we 100% do not have any way to take a picture of a planet outside our solar system that shows any detail of the planet’s surface, and no plans to make a telescope that can do that. What we do right now to even tell if there are planets around other starts is look at the star’s light and see if it gets slightly darker on regular intervals, indicating that a planet is crossing between us and the star in a regular orbit. Right now we can barely take a decent picture of Pluto, which is in our solar system. And checking the light brightness is really only good for looking for large planets the size of Jupiter and Saturn.

    It’s like seeing a car at night on a mountainside 4 miles away with its headlights on. It’s just sitting there and you are wondering if it’s a car or something else. It’s hard to even tell it’s 2 lights, it just looks like one light from that distance. But what would we see if someone walked in front of the car with the headlights on? The light get dim on one side and bright again, then dim and bright again on the other side. Sort of the same thing.

    As for the uncanny valley part, it’s because whoever came up with the graphic just did a random splash of water and land. The planet could be orange and magenta-colored, we have no idea. They used colors familiar to us looking at images of Earth because the intent is to make you think “it’s like Earth, but different.”







  • I recently had a thought that they should retcon this so that the humans were basically GPUs. In the simulation they have lots of people doing complex processing because it’s the late 90s in the simulation. People grind a lot of thinking.

    It’s just like websites that scam you into processing bitcoin mining. But with human brains.




  • The Moon was probably just scared of dinosaurs.

    What’s kind of crazy about the perceived distance thing is that timing of being in this planet now also plays a factor. 100 million years ago a 1ish% relative size larger might have made for far fewer annular eclipses. Or more, I can’t find any info on that, but I expect fewer annular and more total eclipses. Of the 224 eclipses this century, 72 are annular and 68 total.

    But it’s all part of this scifi bonkers planet. Our star makes us have crazy light rivers in the sky at the poles because molten iron inside the planet is spinning faster than the outside of the planet to make giant magnetic currents. The crust isn’t even solid, it’s a slow moving chunky ice flow of silicates, like some busted-ass pie pulled straight from the oven. Huge deposits of dead trees and other early life got buried and remained intact as seams or seas of hydrocarbons, just hanging out. In some places the life that evolved here can die and get buried and some of the remains turned into stone versions of itself. We can bounce radio waves of the inside of the atmosphere and the magnetic currents for our convenience.

    Sorry, but it always sends me down a rabbit hole of how weird this place is and we just get used to it.
