English: The number-line is broken into the two major classifications of dark matter particle hypotheses, particle-like dark matter (e.g. WIMPs) and wave-like dark matter (e.g. axions). The Compton wavelength and Compton frequency of the particles are shown for comparison, along with a few major reference points.
A few of the dark matter particles passing through the Sun or Earth may scatter off atoms and lose energy. Thus dark matter may accumulate at the center of these bodies, increasing the chance of collision/annihilation. This could produce a distinctive signal in the form of high-energy neutrinos. [154]
Scientists studying the earliest black holes may have found an answer to dark matter, putting Stephen Hawking’s theory on the subject back into the spotlight.
One mystery of dark matter is that it makes up the vast majority of all the matter in the Universe, yet we know surprisingly little about it. A new study, based on observations of distant galaxy ...
Dark matter is called ‘dark’ because it’s invisible to us and does not measurably interact with anything other than gravity. It could be interspersed between the atoms that make up the Earth ...
Dark matter: What is the identity and composition of dark matter? [31] Is dark matter a particle? If so, is it a WIMP, an axion, the lightest superpartner (LSP), or something else? Do the phenomena attributed to dark matter point to an extension of gravity instead of some other type of matter? Dark energy:
Furthermore, if the pEDM is found to be non-zero, it can help resolve the matter anti-matter asymmetry mystery of our universe. During his research career, he held a number of positions in the Department of Physics in Brookhaven National Laboratory , including initiator and co-spokesperson of the Storage Ring Electric Dipole Moment Collaboration.
Direct detection of dark matter is the science of attempting to directly measure dark matter collisions in Earth-based experiments. Modern astrophysical measurements, such as from the cosmic microwave background , strongly indicate that 85% of the matter content of the universe is unaccounted for. [ 1 ]
