Scientists create matter from pure light, proving the Breit-Wheeler effect
Long Island The Breit-Wheeler effect, postulated as early as 1934, describes the conversion of light into matter. With the theory physicists Gregory Breit and John Wheeler were able to prove that when two high-energy photons collide, a positron and an electron arise, i.e. matter is formed. Breit and Wheeler postulated a method in which accelerated heavy ions serve as a light source instead of a photon beam. According to the theory of Breit and Wheeler, an ion is surrounded by a cloud of light particles as it moves through a particle accelerator. In an additional experiment, the scientists also checked whether the photons generated during the collision had the characteristics of normal light particles, which was also confirmed. "Our results provide clear evidence for the direct, one-step generation of matter-antimatter pairs from the collision of light - as described theoretically by Breit and Wheeler," explains Daniel Brandenburg. It has therefore been proven that the direct conversion of light into matter is possible.
