Physicists are chasing a number of loose ends in the Universe: Neutrinos, dark matter and energy, matter/anti matter asymmetry and chirality. A beautiful universe is a tidy symmetric one. Yet it is a very topsy turvy place.
Symmetry and conservation laws are intertwined. Symmetry figures large in a grand unified theory. Yet a lot of particles aren’t very and I don’t get a sense that consequence is given to asymmetry as fact. Isn’t there a significant aspect of the universe not subject to conservation laws? If so, are there consequences? Or perhaps some asymmetry is a by product of some other process we have yet to discover.
Let’s take neutrinos. These are very busy little introverts dashing about at c or near c. Perhaps, like the white rabbit, mass and spin of neutrinos slipped their pockets while rushing off to an engagement at table A across the universe, scattering dark matter and energy (spin) in their wake.
Speaking of which, dark matter and energy seem yin and yang to each other. One is holding galaxies together, the other is puffing the universe into Cantor dust.
Or perhaps I should increase my pay grade because here and here
