  • Astronomers discover the largest structure in the universe

    Updated: 2013-01-11 12:41:54
    (Phys.org)—An international team of astronomers, led by academics from the University of Central Lancashire (UCLan), has found the largest known structure in the universe. The large quasar group (LQG) is so large that it would take a vehicle travelling at the speed of light some 4 billion years to cross it. The team publish their results in the journal Monthly Notices of the Royal Astronomical Society.

    Updated: 2013-01-08 16:43:38
    There are two kinds of elementary particles in the universe: bosons and fermions. Bosons don’t mind sitting on top of each other, sharing the same space. In principle, you could pile an infinite number of bosons into the tiniest bucket. Fermions, on the other hand, don’t share space: only a limited number of fermions would fit into the bucket. Matter, as you might guess, is made of fermions, which stack to form three-dimensional structures. The force fields that bind fermions to each other are made of bosons. Bosons are the glue holding matter together.

    Although he was one of the few artists who attained wealth from his trade, Pablo Picasso used inexpensive, common house paint for some of his works. Perhaps more surprising is that, decades after he painted his greatest masterpieces, a facility with fundamental physics roots identified that paint using a powerful instrument to peer, for the first time, at individual pigment particles comprising some of Picasso’s paintings.
