Thank you for your precise explanation based on the standard model of physics and General Relativity. I completely agree with the math behind stable orbits, but I am looking at the "Big Picture" from a more holistic and dynamic perspective, rather than a purely reductionist one.
Allow me to share my vision, supported by both natural patterns and physical numbers:
1. Space is Not Empty; It is a "Radiant Sea"
What we call "Dark Matter" or the vacuum of space is not just an empty void or a dead spherical halo. I prefer to call it "Radiant/Luminous Matter" (A foundational active medium). Physics tells us that the universe is about 27% Dark Matter and only 5% normal matter. Furthermore, a normal atom is 99.9999% empty space.
Therefore, we are not solid objects hitting a wall; we are like a highly porous "Sponge" moving through an immense ocean. This dark/radiant sea permeates us entirely without mechanical friction.
2. The Magnetic Field Analogy (Why we aren't shredded)
You mentioned that if we were in a vortex, we would be shredded by friction or tidal forces. This assumes mechanical friction. But look at a Magnetic Field: Its invisible lines pass straight through wood or plastic as if they don't exist, yet they exert massive force on iron.
Similarly, this "Radiant Sea" does not interact with our atoms electromagnetically (hence, no friction to cause our orbit to decay or shred us), but its presence dictates the macro-dynamics of the galaxy. It guides us without colliding with us.
3. The Universal Spiral (From DNA to Galaxies)
The helical/spiral motion you dismissed as just a visual frame of reference is actually the most fundamental signature of nature. The acceleration and spinning didn't start today; it began ~13.6 billion years ago during the galaxy's formation. Since there is no friction in space to stop it, we carry that initial primordial momentum.
Nature uses the exact same helical blueprint everywhere because it is the most efficient way to manage energy and information in 3D space:
From the micro: DNA (2 nanometers wide) held together by minute cumulative forces.
To the macro: The Milky Way (100,000 light-years across) moving at ~220 km/s.
The fact that this spiral geometry repeats across all scales proves that the fabric of space itself has an inherent twisting dynamic.
We are not just orbiting in an empty curved geometry; we are swimming in a vibrant, fluid-like sea of radiant matter that shapes everything into spirals, from our genes to our galaxy.
