Perhaps the most famous physical formula we know E=mc^2 The formula has never really been tested until now. Einstein According to this formula of , the energy of an object is equal to the product of its mass and the square of the speed of light. Researchers have now designed an experiment to test this theory.

Osaka and San Diego Universities In a collaborative study, computers were used to simulate scenarios in which photons collided with lasers. According to the results, it became clear that as a result of these collisions, electrons and positrons should be created. It is a (+) charged antimatter particle corresponding to an electron. positrons It was also claimed that a positron beam could then be created by accelerating the laser with its magnetic field.

Is it possible to convert light into matter?

Osaka University physicist who co-authored the study Alexey Arefiev, said the experiment they developed is feasible and they expect it to be used in the real world. The researchers’ statement also mentioned that it was possible to conduct this experiment and that lasers of the mentioned type were available. According to simulations Breit-Wheeler process When the process called photon-photon collision occurs, matter can be created.

Senior researcher and physics professor Steven Rose previously described a similar experiment as “This experiment will be a pure demonstration of Einstein’s famous equation regarding energy and mass: we are talking about E = mc2, which tells us how much energy is produced when matter is converted into energy. What we do is the same, but this time the formula is reversed: photon energy to mass convert, i.e. m = E / c^2.” He used the following expressions.

How can the experiment be performed?

One of the visible light thousandfoldthe other is 1 million times Two strong light waves are fired at a gold plate and collide. Inside a small gold tube called a hohlraum, the powerful laser will create thermal radiation. The photon beam will be focused through the hohlraum and the final collision of the photons will occur, creating electrons and positrons. In addition, a large amount of gamma radiation is released during this process.

In theory at pulsars It is thought that photons collided with each other and that is why matter was formed in the pulsar. These celestial bodies also often emit particles and gamma waves into space.
