Dark matter clumps may have punched through star stream
A one-two punch of dark matter may have knocked holes in a stream of stars out past the edge of the Milky Way. If confirmed, these would be the smallest clumps of dark matter we have ever detected. “Potentially, this stream could allow us to probe for the first time how dark matter behaves on a small scale,” says Sergey Koposov at the University of Cambridge. Dark matter is an all-pervasive yet invisible substance responsible for much of the large-scale structure of the universe. We can see its powerful gravitational effects at work, but have never seen it directly and we are still uncertain as to its exact nature. The Milky Way, which is about 100,000 light years across, is thought to sit within

Cosmic Neutrinos Detected, Confirming The Big Bang's Last Great Prediction
The Big Bang, when it was first proposed, seemed like an outlandish story out of a child’s imagination. Sure, the expansion of the Universe, observed by Edwin Hubble, meant that the more distant a galaxy was, the faster it receded from us. As we headed into the future, the great distances between objects would continue to increase. It’s no great extrapolation, then, to imagine that going back in time would lead to a Universe that was not only denser, but thanks to the physics of radiation in an expanding Universe, hotter, too. The discovery of the cosmic microwave background and the cosmic light-element background, both predicted by the Big Bang, led to its confirmation. But last year, a leftover
