Permilab: We discovered clues to new physics

  • 149 תגובות
Last Tuesday, the Premilab laboratories in the United States announced that the muon's magnetic moment does not match the theoretical calculations. The experiment conducted in the state of Illinois confirms the anomaly that was discovered several years ago. Is this evidence of a new fundamental force in nature?

In the study, the scientists examined collisions that occur between the molecules. Collisions of atoms have been studied in the past, but atoms - according to classical physics - are spherical, while molecules have an elongated structure. The structure of a colliding body affects the way it will move after the collision. Will elongated molecules behave differently from spherical atoms? And is knowing their shape enough to predict the outcome of the collision? Illustration: pixabay.com.

In the yellow circle you see a normal form of polarization (E-mode) and in the blue circle you see the form of polarization and the size of the polarization that must have created only gravitational waves during inflation. You can see the same special polarization in the background radiation in the top image as well. The black lines mark the direction and polarization of the radiation. Once the team measured this polarization shape they were able to confirm both the gravitational waves and the inflation phase. In the bottom picture you see a drawing starting on the left side where the big bang happened and immediately after it the inflation (the yellow part). After the end of inflation the universe expands much more slowly (the black part) until the present day. Today we measure the cosmic background radiation that came out when the universe was 380,000 years old and pass it through polarizers to measure the polarization of the radiation (the blue part).

First direct evidence of the existence of gravitational waves that caused the universe to swell immediately after the big bang
