The universe consists of a massive imbalance between matter and antimatter. Antimatter and matter are actually the same, but have opposite charges, but there’s hardly any antimatter in the observable universe, including the stars and other galaxies. In theory, there should be large amounts of antimatter, but the observable universe is mostly matter.

Uppsala University researchers have devised a new model for the universe – one that may solve the enigma of dark energy. Their new article, published in Physical Review Letters, proposes a new structural concept, including dark energy, for a universe that rides on an expanding bubble in an additional dimension.

It was hiding behind the Milky Way.
Through the thick fog of our own galaxy, astronomers have spotted an ultimate prize: one of the largest-known structures in the Universe.
Called the Vela super-cluster, the newly discovered object is a massive group of several galaxy clusters, each one containing hundreds or thousands of galaxies. Continue reading Astronomers have discovered one of the most massive objects in the universe
