70: A new test for cosmological inflation

Scientists call this mysterious event cosmological inflation -- the problem is they have no real idea what it actually is – and what physical mechanisms drove it. *More mystery surrounding an already strange star Last month we reported how astronomers think they may finally have solved the mystery surrounding a weird erratically flickering and dimming star -- whose strange behaviour -- sparked speculation that it could have been our first sign of an advanced alien civilization. However, a new study has reopened the mystery. *Saturn’s moon Dione has a subsurface ocean New data from NASA’s Cassini spacecraft has confirmed the existence of another subsurface ocean on a moon in the outer solar system. Cassini has discovered the ocean under the surface of the Saturnian moon Dione. *Nobel Prize in physics goes to topology in materials This year’s Nobel prize for physics has gone to David Thouless, Duncan Haldane and Michael Kosterlitz for revealing the secrets of exotic matter. The trio used advanced mathematical methods to study unusual phases, or states, of matter, such as superconductors, superfluids and thin magnetic films. If you're enjoying SpaceTime, please help out by sharing and telling your friends.
