I can't explain this one, but I'd like to offer some other identifiers used. When searching for likely planets, they observe stars for wobble in their position. Large planets like jupiter and Saturn have some hefty pull on our own star. The common orbital point between them, called the barycenter, is still inside the sun, but their great distance apart pulls that barycenter closer to the edge of the sun. Our sun has a pretty notable wobble as a result. That's the kind of thing they look for elsewhere. If there's no other star causing the wobble in a binary system, then it must be a planet pulling it.
By estimating the mass of the star by various observations of color, brightness, and brightness variation, they can do some "easy" algebra to calculate the size of the affecting planet. From there, they can scan for radiation frequencies in the darkness where they think a planet is sitting. Water has a frequency, hydrogen has a frequency, oxygen has a frequency, helium, etc. By stuffing objects close to home, we can extrapolate that info and apply it to further objects with some confidence. This is how organic compounds were discovered in Venus' atmosphere.
A lot of it is based on what we have at home, meaning we're largely looking for what we have and then identifying it as the same. There is uncertainty about some details, but that's how it always goes with science. It's always being updated. It's takes a lot of creativity to imagine what else might be out there and to devise how to look for it. Black holes are a pretty notable example. Since they're not observable directly, what do you look for? Well, you look for other things being eaten and hope the matter is hot enough to throw a lot of radiation. 80 years ago, they were just an idea. Now we have images of a few galactic-center black holes. Some have been observed free floating through space by distorting the apparent position of stars behind it. Do we absolutely know it was a black hole? No, but that's what solid theories can identify it as given the darkness and huge mass required to cause that kind of effect. But, as a result, estimates for dark and cold objects vary greatly because they're the hardest to observe. There's talk of finding more "hot jupiters" than expected, but it's totally valid that maybe wevre just missing the cold Jupiter's because they're hard to see.
We keep looking and we keep writing it down.
Damn, that just feels surreal to me. I can't properly conceptualize the scale of the moon I guess
Yes, Bush was the president for most of 2008. Obama got a short portion, although the exact president in place doesn't necessarily tell you if they agreed anyway. Since president's don't really write law, I was looking for the exact law to see the history of which representatives were pushing it. I wanted to see what the angle was for that piece of the bill and what else was attached to it. Nothing gets passed as an individual law, meaning it was probably a rider in a much larger group of laws that likely made it a non-negotiable requirement bundled into a more pressing matter.
But I guess 9+ people read my simple question as total contempt for the situation.
What is that law? Closest I think I can get is HR 4986 sec 227 which mentions Israel, but I can't read further. Who put it in place?
So they want to change their identity based on the feelings and bend existing geo roles to match?
Not really. They want nonwhite unhappy people to leave the country, not change it to their liking. So to comply with their own shoutings, they'd have to physically move to Idaho, not just reroute state borders to their liking.
State borders are fucking dumb under the "one nation" notion. It's 50 colonies in a trench coat, pretending it's different than the EU
"I didn't really understand the technical aspects, which is why I turned to a technical service I also didn't understand"
Standard map projection strikes again. Starting from the tip of South Africa, it's 4300 miles to Uruguay (where you'd land straight east) and 5300 to Perth, Australia. New York City is 3300 miles to Portugal and obviously the smoothest route to Australia is hopping through southeast Asia. Coincidentally, the northern hemisphere has way more population.
Cape Town is only 34° south. Going to 34°N, you're lined up with Los Angeles, Dallas, and Atlanta USA, then Morocco, Algeria, and Tunisia, then the middle of the Mediterranean Sea, Lebanon, Syria, Iraq, Iran, Afghanistan, middle of China, southern tip of South Korea, and grazing below Tokyo. It's still 4100 miles between Georgia (USA) and Morocco.
There are no southern polar flights and no southern undersea cables because the southern continental points aren't as far south as the northern points are north. Population volume doesn't create the demand for more direct service.
Why do people always feel like their inexperience on a topic is relevant?
Probably to politely invite contrasting opinions and experiences from people in the field
I've only found one post in which someone points to a map, claiming the lack of undersea cables between the southern pointy bits of land is evidence they're on opposite sides of the disc.
My entry point was 10x50 binoculars. There's a lot of faint fuzzy white blobs out there to see with them.
As I understand it, about 20 years ago, my [US] state started requiring all new basement work (including additions) to have radon piping provisions, but they didn't have to be connected.
It worked to convince the most anti-communist conservatives to like Putin 15 years ago with tough guy shirtless memes about how you gotta respect his ability to lead people. Sure, why wouldn't it work again?
There's a Regular Car Reviews joke in there. "here's my real car, here's my toy car, my real car, my toy car, real car, toy car, real car, toy car"
I think he went to a car show rather than reviewing a specific car
It's the same 10 pieces on the top of the pile for weeks. Everyone is reaching for the pieces under. As long as it's not 2x2PT
2x2PT has been 1.25x1.25 for as long as I can remember (10 years or more). It's only the pressure treated deck stuff for railings. This does not apply to the rest of the 2x lumber, as those are still 1.5 actual. I got Simpson corner 2x2 brackets for crazy cheap way back but ended up not really using them. The 2x2s are warped to hell and a ripped 2x4 was too big in the original 2x dimension.
I usually bring my 9ft magnetic tape from my car's ceiling and my 4" brass fractional caliper from the glove box into the store but always end up prowling the lumber section for the loose tape measures. Wouldn't want to look like I'm stealing, right?
Eh, I think it's helpful to point that out. If someone hit a dead end researching lasers, not making it out of the visible spectrum, that could explain why. Maybe they missed the line stating where laser ends, maybe the article assumed the reader would know that already.
I beleive a large issue, and I say this as an old man yelling at kids on my lawn, is the difficulty in learning new systems. Most of those bad ones largely changed how to navigate a pc. Most of the good ones were smaller leaps from the prior bad one. So yes, I'm sure that also means the devs had more time in the current style to smooth it out and fix newly broken features, but it also got people exposed to the new style. A huge problem with 8 was that it went to that tablet tile bullshit. 10 tries to be a tablet too, slightly less so, but now we're all accepting it as normal. That's my take, at least as a contributing factor. Whatever was normal in your 20s is the standard for the rest of your life.
I see it with cars. People in my cohort get mad at all the chimey nannies in modern cars, so they yearn for when cars weren't so inundated with technology. Peak automotive design was 1985-2005. And yet, the adults when we grew up would complain those 90s cars are way too complicated with their electronic engine control models and emissions systems.
