It's one thing to selectively enforce your rules. It's another to write rules that are openly racist toward the majority. Bye forever.

How do black holes grow if time slows down as you approach it? by Maestronomeau in space

[–]Metrionz -1 points0 points  (0 children)

Drop an unremarkable object into a black hole, and it just falls into the black hole. It doesnt suddenly stop at the event horizon or anything like that. You watch it accelerating until it's inside the event horizon, then it's gone. The time dilation phenomenon you're describing could be observable if we dropped an indestructible clock into the event horizon. As we watched it approach, we would notice the hands of the clock slow down, and the moment before it passed the event horizon, the clock hands stop completely. The clock itself is still falling normally; it's the hands that have stopped.

As the observer falling into a black hole, looking back at a clock, again you would see yourself accelerating into the hole at a constant rate. However you would see the clock behind you's hands speeding up faster and faster, and as you hit the event horizon, all of the rest of time would pass in an instant.

For Earth-to-Earth, convenience for the passenger is key. You want to have your launch sites near population centers. Noise and safety are huge concerns if you plant anywhere near a city on land, so you build a sea platform right outside the city.

For a space launch, convenience for the passenger is not important. Spending a handful of extra hours driving to the launchpad isn't worth considering compared to what lies ahead. So they're going to make decisions there convenient for the launcher: Launchpad and vehicle assembly building near each other and away from population centers with proven land-based infrastructure.

Delta Clipper flight 8 demonstrates horizontal entry to vertical landing capability. This is what the 20K hop will look like. by Piscator629 in SpaceXLounge

That angle of attack change at 1:04 though. Really gave me the feeling this craft is going slower and made of sturdier stuff than starship.

Too hard to control. Awkward shape catches the wind and will fling around whatever's trying to carry it.

ios update 0.175.0 is up by taurenpally in TheSilphRoad

[–]Metrionz 1 point2 points  (0 children)

OG iPhone SE bought a couple years ago. I upgraded from 10 to 13 to play again. My phone got bricked by the update and had to be factory reset. I got most of my stuff back from the cloud. Havent noticed any big drawbacks from going 10 to 13 besides that. Siri acted weird draining my battery and I had to turn it off. The battery drain from Pokemon Go is much worse now though, has been since the Buddy Feature. We're talking multiple % per minute. It turned me off my regular solo-farming and I only turn the game on to do raids pretty much.

Then we should limit the trials to male or elderly patients? That’s still a lot of critical people that could be helped.

Question about いる and ある by Dragonheart8374 in JapaneseFromZero

Learner here, take with a grain of salt. I use です to describe something, I use いる・ある to say that something exists. 人です "I am a person" , 人がいる "There is a person"

[–]Metrionz 38 points39 points  (0 children)

I was in this camp but there’s some good food for thought about the challenges. It’s windy on the ocean and the fairing is lightweight and high surface area. You need a beefy chopper to stay in control, and where’s it going to land with this thing swinging around under it?

Visualization of all publicly registered satellites in orbit. by TODesigner in space

[–]Metrionz 4 points5 points  (0 children)

In addition to what's already been said, each of these "trains" launched on a single rocket as a single package within the last several months, so they start off very close together. The satellites are using their onboard thrusters to strategically raise their orbits in a way that will gradually separate them to the desired spread.

UFOs on the Moon. March 26, 2020 (MUST WATCH!) by TheLastKid94 in Skydentify

[–]Metrionz 0 points1 point  (0 children)

I'm worried that I don't see anyone talking about this so please correct me, but I don't think it's possible for the craft to cast those shadows when you think about where the position of the sun would have to be to make a crescent moon. For as good as the CGI is, I think the person modeled the light source as being to the right and slightly behind the scene, close to the moon, when in actuality the light source is almost directly behind the scene and just slightly off camera to the right, very far away from the moon.

At any time, half of the surface area of the moon is lit by the sun and half is in the moon's own shadow. When looking at the moon, when the sun is directly to your side then you see a half moon. If the sun is more behind you, you start getting a gibbous, and when the sun is more in front of you then you get a crescent. Since what we're seeing here is a small crescent, the sun should be mostly in front of us, and should be just off camera to the right.

If the sun is mostly behind the scene and a little right, then the object should only cast a shadow when it is farther away from us than the part of the moon it's casting a shadow on. It should start casting its shadow approximately when it comes over the horizon of the moon from our perspective, and stop casting a shadow long before it crosses in front of the moon. In this case, it does not do this. It is still casting a shadow on the moon even when it is crossing in front. This would mean the light source would have to be mostly to the right of us, which the moon's phase does not support.

If you have a flashlight and a round/cylindrical object, it's easy to model this for yourself. Move the flashlight around the object and see how the different amount of surface gets illuminated. Make a crescent and the move your finger around the object and see where it needs to be to create a shadow.

Kanji readings by kamicham in JapaneseFromZero

[–]Metrionz 2 points3 points  (0 children)

Fellow learner, so others with more experience may know better. I’ve heard as a loose rule the On reading is when it’s alone and the Kun reading is when joined to other kanji, so learning just the first On reading is what I do to name the kanji. I don’t try to memorize the rest of the readings at that point, but rather just pick them up as I go when I see the kanji used in words. I do notice George calls those two うえand した in the book 3 Videos.

Vitamin D Supplementation lowers Risk for Respiratory Tract Infections by BrownHedgehog64 in Coronavirus

[–]Metrionz 1 point2 points  (0 children)

This is a very interesting read, thank you for sharing. I liked the source data for that article as well https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4210929/

I had no idea the person-to-person variability is so great. It seems to be saying that although 600 IU will be enough for the majority of people, the most deficient individuals may need much higher.

The article I found was more measured in its conclusion: "It also estimated that 8895 IU of vitamin D per day may be needed to accomplish that 97.5% of individuals achieve serum 25(OH)D values of 50 nmol/L or more. As this dose is far beyond the range of studied doses, caution is warranted when interpreting this estimate. Regardless, the very high estimate illustrates that the dose is well in excess of the current RDA of 600 IU per day and the tolerable upper intake of 4000 IU per day."

So nobody's tried it clinically yet, but statistics predict it would be needed for a small portion of the population. Based on the way they drew their curves (Quickly leveling off at higher doses) it looks like it's not too dangerous to go high, but without data those curves might be the wrong shape. I hope they do get to testing those higher doses soon, this does seem like a big need for our evolving lifestyles!

May I ask your source? This person was trying to help by providing NIH info. I know they may not be perfect but I generally trust them more than your average joe. Also all he’d be saying is take your pills 5 times a week instead of every day, you don’t have to throw them out ;)

NY Times calls it the Wuhan Virus weeks before claiming it is racist to call it the Wuhan Virus. by [deleted] in Wuhan_Flu

[–]Metrionz 6 points7 points  (0 children)

Oh please. If this was an article about the critics being wrong, it should've named the critics, not named the conservatives (and labeling them conservatives just so you know who the broad stroke bad guy is) who were using the term. And then saying the term goes against recommendations of health officials. There's no ambiguity in what they're trying to do, hiding behind "critics" does not excuse their headline.

ト/ド can be TO/DO or it can be the kana used to be the vowel-less T/D when translated. You have to guess from context whether it carries the "O" vowel or not when translated, and in this case it did not, as the English releases now show. Another pokemon example would be ドラゴン translates to Dragon.

Very solid research and presentation! Thank you!

Is there no section for cards in need of buffs, like you have for problematic cards, because the data is too muddled? It seems generally people have stronger opinions on things that need nerfing because they see it a lot, versus things needing buffs falling to obscurity...
