A contemporary find out about from the University of Melbourne described how increasing bubbles in the early universe may well be the key to figuring out dark matter. Scientists proposed a mechanism that suggests- the dark matter abundance can have been decided in a cosmological segment transition.
Dr. Michael Baker, a postdoctoral analysis fellow at the University of Melbourne, mentioned, “These phase transitions are expected to have taken place in the early universe and can be similar to bubbles of gas forming in boiling water. We show that it is natural to expect dark matter particles to find it very difficult to enter these bubbles, which gives a new explanation for the amount of dark matter observed in the universe.”
This new theory for the origin of dark matter helped experimentalists in Australia and out of the country seek for the mysterious new matter.
The analysis, which was once achieved in collaboration with Assistant Professor Andrew Long from Rice University, Texas, and Professor Joachim Kopp from CERN and the University of Mainz, issues to new experimental methods for looking out for dark matter.
Dr. Baker mentioned, “If it’s a new particle, then there’s a good chance that we could detect it in a laboratory. We could then pin down its properties, like its mass and interactions, and learn something new and deep about the universe.”
Professor Kopp mentioned, “One exciting aspect about the idea is that it works for dark matter particles that are much heavier than most other candidates, such as the famous weakly interacting massive particles, on which most experimental searches in the past were focused. Our work, therefore, motivates the extension of dark matter searches towards heavier masses.”
The findings may well be particularly a very powerful for the long run of experimental dark matter searches in Australia.
