Theory for the expansion of the universe

I was on a 4-hour bus trip on the way home then a thougt came into my mind about a video that I watched years ago from YT which I forgot the channel, it was probably Vsauce, the video demonstrates how a 3D object passing through a 2D plane will look like, as the 3D object pass onto the plane, it will first create a point that gets bigger in all directions from the center of the point in 3D, this makes sense because of "height" since the bottom is the narrowest part then the center or the bulge of the balloon being the widest then to the top which is also the narrowest part but on a 2D plane it would just look as if the balloon is appearing from thin air and expanding from the first point outward in all directions then disappear again, now if I remember correctly dark matter is the reason for the expansion of the universe and that expansion is equal in all directions as if the space between galaxies itself is being made or getting more/larger although that won't make sense because where did the expansion come from? Like Newton's law every action has an opposite reaction right? You can't just expand something out of nothing using nothingness, unless the force comes from a higher dimension, let's go back to the balloon experiment and think of the balloon as dark matter, it would seem as if dark matter is appearing everywhere all at once without a single point, instead of a balloon it's like a flow or river that runs through our 3D plane which in turns causes the expansion of everything away from itself, because the force comes from another angle from us the same way someone looking from the 2D plane won't know where the balloon is coming from.

Feel free to prove me wrong PLEASE, I'd rather be foolishly be corrected rather than being confidently wrong about this kind of topic.

It's just something that crossed my mind that I thought works and what are your guys thoughts about this, if it's already common knowledge then my bad for wasting y'all's time ✋🫪🤚
