Reply to comment by JoyGodLives in ELI5 if a plane flew really high then hovered for 24hrs, would it rotate with the earth, or would it be able to watch the land rotate? by JoyGodLives
”orbital velocity” is the speed and direction you need to go to continuously fall and always miss the ground.

Say you do pay it. Then the next film doesn't do as a well. Now you're salty you paid so much for poor results, and don't hire that director back for the next film.

TLDR: no
The short answer is planes can't hover because they need air flowing over their wings to fly. If they were to have zero ground speed they would immediately crash.
To achieve what's called a Geo-synchronous orbit (where the GPS satellites are), meaning that you are hovering directly above a specific spot and stay there, you actually need to go very high into space and speed up a lot to get there and stay there. It has to do with orbital mechanics, and outside the scope of this ELI5.
The long answer is that you have to factor in is momentum.
The reason we have a hard time conceptualizing this is because humans don't feel how fast we are moving, we feel acceleration and deceleration. That's why when a car or a plane gets up to speed you feel the same as if you are standing still. You only feel it when the vehicle is speeding up or slowing down.
You sitting still is actually moving around at around 1000mph because that's the speed the Earth is turning. You are also moving at around 30km per sec because that's how fast the Earth orbits the sun, etc etc
That's why we have to speak in relative terms. You sitting still means you aren't moving relative to the Earth spinning, because everything you are comparing yourself against in terms of movement is also spinning around at 1000mph.
If you were to suddenly remove all the momentum an object has relative to the Earth, the Sun, the Galaxy, etc it would go flying off into space at several thousand meters per second... because everything else would fly away from it in an instant.
If you really want to blow your mind, The Earth is rotating from West to East, so when you move East you are moving the speed you are walking + the rotation of the Earth. But when you are moving West you are moving the speed of the Earths Rotation minus you walking speed. So a person walking due West is moving slower than a person sitting still. It's all relative to how you measure it.

Oh, that sounds interesting. Just going to find out what orbital velocity means..(don't judge!)

Consider this, you have a director who makes your first movie. The first movie makes hundreds of millions of dollars at the box office, and is a huge success. Now, the director wants triple the salary to make the 2nd movie. Do you pay it? Or do you hire someone else at 1/3 the cost, and just tell him to try to make the tone consistent?
Also, directors are artists. Many artists don't want to spend 10 years making the same product over and over again. You do one movie, you get the experience, and then you move on to something new.

Surgery went well it's been 10yrs or more but my cousin still eat things he isnt supposed to so creatitine even know is still flactuating. I think the doctors and hospital staff knew that they weren't family. The prison warden also knew. Everything can be bought here.

It depends on how you consider "hovering." If you mean zero ground speed, it would rotate with the earth. If you mean zero orbital velocity, the earth would rotate under it but it might have to maintain some crazy airspeed to keep that location in the sky.

Light travels as a wave but interacts as a particle.
Another aspect is wavelength which affects frequency, or how many wavelengths of light will pass a certain point per second. The shorter the wavelength, the more can pass that point in a given time, so the more energetic the light. Light does oscillate, and the rate at which it oscillates might be related to the frequency.
That's enough info to start your student browsing a rabbit hole of science. knowledge in internet searches. YouTube is good for the visuals and science explainers like Arvin Ash and Science Asylum
If your student is interested in the quantum model, the light doesn't exist (in the form we know) until interacted with. Whatever the unformed photon is before it becomes a photon, imagine it as an expanding sphere that's a collection of possible locations where each photon could interact, the expanding at the speed of light, and when the photon emerges to interact then all the other possibilities vanish instantly (faster than the speed of light).

If only one could devise a computer system which does that automatically...
In the UK you can check your account balance on any bank's ATM. Clearly they share that information here. Why not in the mighty USA?

The plane needs the atmosphere to float. The atmosphere rotates with the Earth and so would the plane.

Isn’t that tradition though? I’m not trying to be a smart ass but that seems to be the way the world works. The more talented we are the younger we die.
I’m not suicidal but I recognize that my life is limited and tbh a part of me thinks that if I die young, I might have a better chance of becoming a legend. I know that’s sick and twisted but it seems to be true

Terms and conditions here are meaningless. Its just self-imposed rules, as the owner of the platform, they can take any action they choose for any reason, there is no legal reason they cannot do this. They are specifically choosing not to.

America is the only country has has these ridiculous rules, and there hasn't been a single accident blamed on someone's cell phone or laptop. Feel free to just pretend you're following the rule.
Your phone is capable of transmitting on frequencies that aircraft equipment might use. This theoretical interference is as far as it goes.

They could shut them down if they wanted. They own YouTube. They can do anything they want. There is no barrier for them to act in any manner they choose. They can and do take channels down and need not provide any reason.
Who said they are NOT tracking them? Who said authorities do not know who they are and that google and others are working with them? I don't think we know that so can't make any assumptions.

Google (well, Alphabet) owns YouTube. They have 100% control over what is allowed to be uploaded and what is removed, because it is on their servers. So they can remove whatever they want. But if the content is not violating the rules they have no reason to remove it.

Took like 10 tries to actually upload the program to it even if your code worked, it sucked

In art class, we learned that sometimes men posed as women, so sometime the girls look muscular. And sometimes the painter would edit the buyer’s features out of either courtesy or to avoid being executed hahahahahahahaha.
She said the general assumption was that a lot of ladies were hairier, especially in the older ones.

MCU is actually a bad example here. Because generally directors are tied to a single property there (like say Black Panther or Thor), which isn't on a breakneck timeline. MCU all exists in the same universe, but its not really a franchise in the same manner. Additionally MCU just kinda does stuff different than anyone else since its less of a director-focused/owned project.
For your suggestion, a thing like Star Wars 7-9 is more a valid thing as these are all sorta happening at the same time so they need to divide the work to get it on time.

Is this how a fly in your car also works? Even though we are moving at 60mph, they can still fly around the car as if it was sitting still because the atmosphere for the is also moving?
