This is a great and disruptive discovery, what is light? How is light generated?
First of all, we need to understand what light is, as we all know, light is a necessary condition for our daily life, without light, the world will be dark. The Bible says that at the beginning of creation, there was darkness around God, and God said there would be light, and light was produced. As a current scientific understanding, the production of light is stimulated by electrons in the outer layer of the atom, and the general production of light is mainly through thermal motion, transition radiation, stimulated radiation and other ways.
So in addition to the above common ways of generating light, what other ways can you know to produce light?
Recently, there was exciting news in the scientific community that scientists discovered that gravity can produce light under certain conditions, which is undoubtedly a major breakthrough in the history of science.
A recent paper published in the journal Science titled "Graviton to photon conversion via parametric resonance" (converting gravitons into photons through parametric resonance) sparked heated discussions in the scientific community.
The paper outlines how gravity produces light. Scientists have found that under certain conditions (such as the strong gravitational fields present near massive objects such as black holes and neutron stars), gravitational and electromagnetic interactions convert gravitons, the quantum carrier of gravity, into photons (quantum carriers of the electromagnetic force). The paper also shows that gravitational waves cause vibrations in the equations of motion of all matter fields, and that photons, as the only field without mass, cause gravitational wave instability, which dissipates the energy of gravitational waves. Scientists have found that resonance effects do exist in this phenomenon.
What is parameter resonance, the most understandable metaphor is that when we swing, the trajectory of the center of gravity will change periodically to form a trajectory diagram. The paper shows that parametric resonances played a crucial role in early cosmology for transferring energy to regular matter at the end of inflationary periods.
The interaction between gravity and light plays an important role in studying the behavior of charged particles in the early universe. The study also found a new direction for exploring dark matter and dark energy.
However, the study is currently only in the theoretical stage, and more experimental evidence is needed for the real discovery. The conditions required for the mutual conversion of gravity and photons can only be achieved in extreme environments.
Perhaps for how to achieve the transformation of gravity and light, we also need to involve the study of dark matter and dark energy. We still need to go a long way to study how gravity produces light under specific conditions. However, this discovery may completely subvert the understanding of astrophysics and cosmology, and open a guiding light for our exploration of the universe. We must firmly believe that one day, the new doors of the universe will open for us, and we just need to be brave and explore.
