Scientists find a way to create matter from light by colliding photons,and looks like that impossible dream is close to becoming reality.
Researchers at Imperial College London have developed a method of achieving light to matter transformation, by colliding two sets of super-energetic photons.
They achieve this at power levels of magnitude lower than previously thought possible and the photon-to-photon collider would use equipment that already exists.
Professor Steve Rose from the Department of Physics at Imperial College London said:
“Despite all physicists accepting the theory to be true, when Breit and Wheeler first proposed the theory, they said that they never expected it be shown in the laboratory. Today, nearly 80 years later, we prove them wrong. What was so surprising to us was the discovery of how we can create matter directly from light using the technology that we have today in the UK. As we are theorists we are now talking to others who can use our ideas to undertake this landmark experiment.”
Lead researcher Oliver Pike who is currently completing his PhD in plasma physics, said: “Although the theory is conceptually simple, it has been very difficult to verify experimentally. We were able to develop the idea for the collider very quickly, but the experimental design we propose can be carried out with relative ease and with existing technology. Within a few hours of looking for applications of hohlraums outside their traditional role in fusion energy research, we were astonished to find they provided the perfect conditions for creating a photon collider. The race to carry out and complete the experiment is on!”
