Lasers could be used to create matter and antimatter from vacuum in a theoretical physics breakthrough
Arxiv – Pair Creation in QED-Strong Pulsed Laser Fields Interacting with Electron Beams (25 pages) QED-effects are known to occur in a strong laser pulse interaction with a counterpropagating electron beam, among these effects being electron-positron pair creation. We discuss the range of laser pulse intensities of J ≥ 5 · 10^22 W/cm2 combined with …
