Explaining a universe composed of matter

by Norwegian University of Science and Technology, Phys.org

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.

The Five Ways The Universe Might End

Looking out at the Universe today, it’s easy to be absolutely awed by all that we can find. The stars in our night sky are just a tiny fraction — a few thousand out of hundreds of billions — of what’s present in our Milky Way. The Milky Way itself is just one lonesome galaxy out of trillions present within the observable Universe, which extends in all directions for some 46 billion light-years.

Our universe: An expanding bubble in an extra dimension

by Uppsala University, Phys.org

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.

Astronomers have discovered one of the most massive objects in the universe

by Dave Mosher, Science Alert

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
