Scientists have built a radio receiver for dark matter: a layered semiconductor device turns invisible axions into light. By tilting it in a magnetic field, you can scan frequencies without moving parts—a chance to finally catch the substance that makes up a quarter of the universe.
🎯 The name 'axion' was a joke by Nobel laureate [scientist:Frank Wilczek]Frank Wilczek[/scientist]: he used the brand of Axion laundry detergent because the new particle 'cleaned up' the theory's inconsistencies.
f = \frac{m_a c^2}{h}
Relation between the axion mass m_a and the photon frequency f (c is the speed of light, h is Planck's constant)
