| Sep 5 at 6:17 | comment | added | naturallyInconsistent | Consider the collision between two particles in highly degenerate matter. If both particles are deep inside the Fermi surface, then all the otherwise possible collision outcomes are already occupied by other particles, and so they are forced to be unable to collide and instead have to essentially pass through each other (note that by symmetry, this is equal to reversing each other out of the collision). The bits that are left able to collide, are particles near the Fermi surface. Those contribute a vanishingly small proportion of particles, and so on average, collisions are unlikely. | |
