The mystery of the missing universe
The particle that cleaned up physics
Catching a ghost with giant magnets
The extreme cosmic laboratories
007skaty The Ghostly Wanderers
These ghostly wanderers are turning into light (Turning into light!) Our supercooled magnets will catch them tonight (Catch them tonight, yeah!)

007skaty Without Peccei and Quinn's mechanism, the neutron would have a measurable electric dipole moment, but experiments show it is virtually zero.

007skaty The Peccei-Quinn mechanism predicted a brand-new ultra-light particle to explain dark matter.

007skaty Weigh cosmic particles to discover why the axion is the lightest dark matter.
The Axion name: Nobel laureate Frank Wilczek named the axion after a popular supermarket laundry detergent because it cleaned up a messy physics problem.
A hypothetical, extremely lightweight subatomic particle proposed as a candidate for dark matter. Frank Wilczek named the particle in 1978 after a popular brand of laundry detergent.
In 1977, which two physicists proposed the elegant symmetry mechanism that accidentally predicted the axion?
007skaty Scientists study ultra-lightweight axions as candidates for invisible dark matter
What subatomic particle's lack of a measurable electric dipole moment puzzled physicists, leading to the axion theory?
What messy problem in quantum chromodynamics did the hypothetical axion particle successfully clean up?
Which Nobel Prize-winning physicist officially named the axion after a supermarket laundry detergent?
How does the estimated mass of a single dark matter axion compare to that of a familiar electron?
If axions are so incredibly light, how could they possibly make up the bulk of the universe's mass?
Because axions are feebly interacting, what would happen if an axion passed directly through the Earth?
