A University of Portsmouth physicist has explored whether a new law of physics could support the much-debated theory that we are simply characters in an advanced virtual world.
The large-scale structure of the universe—the gigantic, hierarchical cosmic web of structures bound by gravity—is mostly made up of dark matter. The growth of the large-scale structure, from individual galaxies to galaxy ...
Thanks to the latest Gaia satellite catalog from the European Space Agency (ESA), an international team led by astronomers from the Paris Observatory–PSL and the CNRS has achieved the most accurate measurement of the mass ...
Einstein's theory of gravity—general relativity—has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure at spacetime singularities ...
One of the most interesting and important questions in cosmology is, "How much matter exists in the universe?" An international team, including scientists at Chiba University, has now succeeded in measuring the total amount ...
A collision of two massive clusters of galaxies when the universe was half its current age should not have happened according to the standard theory of cosmology, says a new study by an international group of astronomers, ...
We have built telescopes in our backyards, and high upon remote mountains, and even launched telescopes into space. With each advancement in our technology, we have made amazing and surprising new discoveries about the universe. ...
As the universe evolves, scientists expect large cosmic structures to grow at a certain rate: dense regions such as galaxy clusters would grow denser, while the void of space would grow emptier.
New research, published in The Astrophysical Journal, has revealed the distribution of dark matter in never-before-seen detail, down to a scale of 30,000 light-years. The observed distribution fluctuations provide better ...
Our best understanding of the universe is rooted in a cosmological model known as LCDM. The CDM stands for cold dark matter, where most of the matter in the universe isn't stars and planets, but a strange form of matter that ...
