And Bernoulli Principal is an an idealization,not exists in real world.Fluid dynamics is very very complex,that's why we need All kinds of wind tunnels for text and text especially to high speed aircraft
Bernoulli Principal is an application to fluid dynamic, it is a law a physical properties MUST follow in order to make sense, it is not an optional extra....
And it did exist in real world, because that is coming from real life example. And that is going to be true until one can develop a counter argument via an actual example and experiment. And its looking pretty strong consider it has been 300 years since it is around and yet no one can provide a counter example.
Movement and orbit are two different thing. But just because an object in orbit does not mean that it’s not moving or not in motion. They are only in motionless relative to another object such as a geostationary satellite in “perfect” geostationary orbit. But both are still moving.
This is like two cars moving at 100 miles an hour next to each other. These two cars are next to each other and are static when compare to one another. But both are still moving in reality. Just like our sun and solar system and even our whole galaxy is moving and intercepting Andromeda.
As for the moon, the earth tides are pushing it away gradually. And eventually, it will leave the earths orbit if you give it enough time. So technically, there is no such thing as an infinite orbit. Only the short life span of men and even human existence that we regard planetary orbits as constant.
First of all
As I said, you can define "Move" by anything, if you define "move" by the meaning, it can mean movement, a kind of emotional expression, or relocation in layman term.
However, in physics, movement refer to movement in motion, which describe a motion of a body. Which mean a net force applies to an object and the object is move with certain speed at a certain direction (vectoring) and without any of the 3 (force, object, vector) there are no motion.
You cannot use two cars going at a constant speed and compare it to orbiting. Because one is linear motion while the other one is a circular motion. Those are different in circumstance, first of all, car can acceleration independently, while moon orbit is due to the weight and gravity of earth ALONE. Second of all, just because both car travelling at the same speed, it depend on how or where you put the frame of reference, it can be both uniform and non-uniform motion as well. Which mean the cars can be both "moving" and "not moving" at the same time
And finally, the term infinity does not applies to anything regarding to this universe, if we need to start an infinity theory, then we cannot deduce anything out of this current universe. Because if you have enough time, anything
COULD change, the keyword is "Could" and that is because one can never know or never can know the certainty, and if your argument is "it
MAY come and something
MAY disproof it in the future" then no physics theory are acceptable because they can literally all be disproved IF a counter-event occurs, and the beauty of this game is,
YOU MAY NEVER KNOW because no one live in infinity. Which render
EVERY physics theory useless.
The universe itself is 13.799 ± 0.021 billion years old, and things according to the scientist have maintain the same order since the beginning of the universe. In this 13.799 ± 0.021 billion years, the earth continue to orbit the sun, and the moon continue to orbit the moon. Yes, human is just a speck of life in the universe, but 13.799 ± 0.021 billion years is also a very long time, and either we argue with CURRENT physics or we are not going to argue at all if we are talking about time in infinity.
