Search of ways of combining conflicting scientific models in “theory of everything” that describes all fundamental interactions, one of the most important tasks of physics. The Observatory had one of the first experiments in this field, examining the cosmos in search of hypothetical particles that could tie the Universe together.
Why you need a “theory of everything”
The standard model of particle physics explains the Universe pretty well at the microscale, but when it comes to macroscopic objects, it begins to fall apart. For example, one of the largest of its spaces is that it does not include gravity.
On the other hand there is the General theory of relativity, which has repeatedly proved its reliability in describing the physics of massive objects like planets, stars, galaxies and galaxy clusters. Unfortunately, she also starts to fall apart when confronted with phenomena at the quantum level.
One of the contenders for the title of theory of everything – string theory. Briefly the idea is that every particle that we consider to be a “dot” can be considered a string. The properties of this particle, its mass or charge, are determined by its vibration. In this theory, there are many different versions, but the problem is that her evidence cannot be found. But science does not like the idea that you cannot prove.
However, it is possible for string theory all is not lost. It assumes the existence of hypothetical particles called axions, which, oddly enough, turn into photons passing through a magnetic field. They could be the needed proof.
The Search Of Axion
An international team of scientists used to search for axion x-ray space Observatory “Chandra”, pointing to the cluster of Perseus, located 240 light years from Earth, reports the New Atlas. In the galactic clusters there is a giant magnetic field, and a bright x-ray sources. So if there is a Aksion, astronomers will be able to notice them.
The team studied data collected by the Observatory for more than five days. In particular, the telescope measured the power of x-rays that have arisen as a result of the fall of matter into a supermassive black hole located in the center of a galaxy cluster of Perseus. If there were axions, Chandra would be able to detect them.
Unfortunately, there were none. This does not mean that axions do not exist. Perhaps they have a large mass, or they turn into photons is not as easy as it seemed. So, while “the theory of everything” remains elusive.
