The theory that dark matter (dark matter) is an 'elementary particle that can move in five dimensions' is announced.

About 25% of the universe is

thought to be composed of a mysterious substance called ' dark matter '. Various studies have been conducted to clarify the details of dark matter, but at the time of writing the article, observation of dark matter has not been successful. A new theory has been announced to explain such dark matter using particles that exist in the five-dimensional world.

Particle Could Be Portal to Fifth Dimension | What Is Dark Matter

Research on elementary particles, which are the smallest units that make up the universe, is being actively conducted, and a standard model ' standard model ' that can explain various phenomena related to elementary particles has been established. However, the Standard Model cannot explain dark matter, which is thought to occupy about 25% of the elements that make up the universe. Therefore, there is a need to establish a new physics model that can explain dark matter.

A theory that explains such dark matter by making full use of a theory called '

brain world ' that 'the universe is like a film embedded in high-dimensional space-time' is published in the European Physical Journal . it was done.

In 'Brain World', the interaction of the elementary particles of the Standard Model is confined in the 4-dimensional worldsheet, and it is said that only gravity can move to extra dimensions after the 5th dimension. The research team used models such as the ' Randall-Sundrum model ', which is one of the models to explain the brain world, and the interaction ' Yukawa interaction ' of elementary particles proposed by Hideki Yukawa , and called ' fermions '. If there is an elementary particle called that can move in five dimensions, that elementary particle is the dark matter. '

At the time of writing the article, the existence of dark matter has not been confirmed. However, the technical magazine Popular Mechanics said, 'The theory published this time shows that if there is a gravitational wave detector that can observe'fermions that can move in five dimensions', dark matter can be observed,' said Dark Matter. I have high expectations for the detailed elucidation of.
