A team of astronomers has discovered that several of the small — or 'dwarf' — galaxies orbiting the Milky Way were likely stolen from the Large Magellanic Cloud, including several ultrafaint dwarfs, but also relatively bright and well-known satellite galaxies, such as Carina and Fornax.
Read morePhysicists at Stockholm University and the Max Planck Institute for Physics have turned to plasmas in a proposal that could revolutionise the search for the elusive dark matter.
Read moreScientists have found that the early universe, and the very first galaxies, would have looked very different depending on the nature of dark matter. For the first time, the team has simulated what early galaxy formation would have looked like if dark matter were ''fuzzy,'' rather than cold or warm.
Read moreNew research has simulated dark matter in a new way for the first time, disrupting conventional thinking about the make-up of the universe.
Read moreAccording to quantum physics, energy can be 'borrowed' — at least for some time. Energies lower than zero are possible, much like a bank account that can be overdrawn. There are, however, certain restrictions to that. Scientists have now shown that these restrictions are very fundamental properties of our universe and must be true for various possible quantum theories.
Read moreDark matter is only known by its effect on massive astronomical bodies, but has yet to be directly observed or even identified. A theory about what dark matter might be suggests that it could be a particle called an axion and that these could be detectable with laser-based experiments that already exist. These laser experiments are gravitational-wave observatories.
Read morePhysicists and computer scientists have developed a new approach to the problem of dark matter and dark energy in the universe. Using machine learning tools, they programmed computers to teach themselves how to extract the relevant information from maps of the universe.
Read moreThe origin of matter remains a complex and open question. A novel experimental approach could be exploited to better test the theories of physicists.
