The sun stays in its arm of the galaxy it’s not rotating through it faster than the galaxy is spinning. The solar system isn’t travelling like that it’s not a useful representation of how it moves.

Why the Viral Vortex Animation is Wrong
Perpendicular Tilt Myth: Viral videos falsely show the planetary orbital plane perpendicular (90°) to the Sun's direction of travel. The real ecliptic is tilted at roughly 60°. [1, 2, 3]

Trailing Planets Myth: Because of this 60° tilt, planets are not dragged behind the Sun like a comet tail; they spend time both in front of and behind the Sun relative to its galactic path. [1, 2]

Vortex Fluid Misuse: A vortex is a fluid-dynamics term involving drag and friction (like water in a drain). Space is a vacuum, and planets are bound by gravity, not fluid resistance. [1]

The planets are in front of and behind the sun in the video. The person simplified that part of this to show something else. Nice use of AI btw -.- "Ai tell me exactly what I want to hear and disregard the topic at hand"

Uh huh, and the sun is zooming around while the galaxy stays still?

Do you remember in school when being taught about atoms they showed us a nucleus with static circles showing where the electrons orbital said nucleus? Do you remember when they told us later on that that isnt how atoms actually look ad that it was demonstration purposes to teach us?

They removed unnecessary information as to not bog down the point they were making. Its not that what they taught wasnt true, but it was the whole truth. I guess the nuance is lost on you tho :/

So both depictions are useless and wrong? Thats your big point? Wow.

No, my point is they sacrificed accuracy in one aspect to focus on a diff one. Like one does when making a 2d map of a 3d sphere, accuracy is lost somewhere. You need better reading comprehension...

Lock in a child’s understanding of something if that’s your play bro. It’s a meaningless point anyway who cares how many orbits life took to evolve it’s not a relevant metric.

A subjective timeline of the history of the only planet we know has life... is irrelevant? Are you not from earth?

You quote AI to me, but claim that I have no understanding? The irony cant go over you head... right?

Wtf does that even mean, lock in a child's understanding? Becuz I mentioned how we were taught electron orbitals? I was talking about how they withheld the fact that it isnt 100% how it works, but it gets our understanding at least partially in the conversation. My "play" was explaining that with complicated concepts sometimes starting with less information than is needed is best. Everything in the left-most column of the periodic table is explosive in water, but starting there doesnt teach anything about the elements themselves so why mention it at the beginning of the educating process. Nuance is lost on you, Dunning-Kruger

lol, okay kid. Just a lot of irrelevant ‘what abouts’, no defence of the nonsense in the video and thinking saying DK over and over is some kind of flex. My main emotion is pity.

You used AI for your thinking... idk what you mean "what abouts" you literally havent been explaining your random collections of words. I didnt say "what about" for anything. I have answered you, but you wont answer me. You are either not as smart as you think you are (Dunning-Kruger) or you are communicating in bad faith (troll). Either way, weak sauce
