Researchers Prove Black Theory in a Laboratory Setting

Researchers at the Advanced Science Research Center at the CUNY Graduate Center have demonstrated a new approach to wave amplification through interaction with rotating bodies. Rather than mechanically rotating matter, however, the team engineered a radio-frequency device with properties modulated in space and time to mimic spinning.
