Particle spin is the orientation direction of a particle.
Flat 3-dimensional particles have a “spin” of 1/2 in Physics because they can flip.
Linear and columnar particles have a “spin” of 1 in Physics because they are rigidly linear.
However, there are particles that can be linear and flat. Examples are:
- spacetime particles
- heat particles
Particle spin is the orientation direction of a particle.
For example, heat has a force that can make things expand. This is when heat switches from linear, going with photons, to flat, going with spacetime.
Likewise, spacetime particles can go from linear, as the force of gravity and dark matter, to being flat, as energetic vortices (barycenters) or empty space which have less energy.
