Hi...Stuart with the Show Notes for Series 19 Episode 70...and you can find enhanced Show Notes, including photos to accompany this episode, at http://www.bitesz.com/spacetime-show-notes *A new test for cosmological inflation When the universe burst into existence in the big bang 13.8 billion years ago – something must have happened during the first nanoseconds that caused it to suddenly expand from a singularity of infinite density and virtually zero dimensions in to the universe we see today. 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.
