There are many ways to learn more about dark matter, in addition to the experiments. There is one way accurate measurement of cosmic characteristics (proportion of helium in the universe or the temperatures of different particles at the birth of the cosmos). New research led by a group of physicists has explored a method to predict the composition of dark matter. The method is the Big Bang Nucleosynthesis (BBN): A process to create light forms of matter, such as lithium, hydrogen and helium. The formation of these elements is influenced by invisible dark matter. The research team aimed to identify a specific category of dark matter with a mass between that of the electron and the proton.

Such dark matter may alter the abundance of some elements produced in the early Universe and leave a footprint in the cosmic microwave background by altering the rate at which the Universe is expanding. Brighter forms of dark matter can cause the universe to expand so quickly that these elements have no chance to form. We learn from our analysis that some dark matter models cannot have too small a mass, otherwise the universe would look different from what we observe.

The research results include predictions of Fingerprints of the cosmos in combination with specific types of dark matter. The footprints, considered “signatures,” come from dark matter that changes the temperature of the particles or the rate of expansion of the cosmos. Furthermore, it was found that dark matter that is too light can produce different amounts of luminous elements compared to the detections of astronomical observations.
