The Large Hadron Collider sprung back to life this month, smashing subatomic particles with nearly double the energy used to discover the Higgs boson, a landmark in understanding the makeup of the physical world. With the Higgs now in the bag, researchers are setting their sights on more exotic fare: signs of a new physics that not only describes the universe but explains why it is the way it is.

Big Bang Mystery Extends Into Nearby Galaxy, Puzzling Cosmologists

A photo of star cluster Messier 54.

New observations of the star cluster Messier 54, shown above, reveal that it is just as strangely deficient in lithium as our own galaxy, deepening a mystery about the element’s big bang origins.

Theory suggests stars should contain three times as much lithium as they do.

Προβολή του προσώπου του Αλμπερτ Αϊνστάιν σε ένα σόου με λέιζερ που οργάνωσαν Κινέζοι φυσικοί στη Σαγκάη. Το Διεθνές Ετος Φωτός, που γιορτάζεται φέτος, εκκινεί, εν μέρει, από τη Γενική Θεωρία της Σχετικότητας, που ο Γερμανός φυσικός διατύπωσε εκατό χρόνια πριν. Οι δράσεις που θα πραγματοποιηθούν παγκοσμίως θα φέρουν κοντά αστρονόμους, φυσικούς και μηχανικούς με καλλιτέχνες και στοχαστές.

Four years ago, Anna Frebel, a young astronomer at the Massachusetts Institute of Technology, found an ancient star in a neighboring galaxy whose chemical composition proved nearly identical to some unusual stars on the outskirts of our own galaxy, which are older than the Milky Way itself.

CAMBRIDGE, Mass. — One night late in 1979, an itinerant young physicist named Alan Guth, with a new son and a year’s appointment at Stanford, stayed up late with his notebook and equations, venturing far beyond the world of known physics.

Big Bang cosmology and the evolution of the universe

Posted onSaturday 8 February 2014 theguardian.com

 

Is the universe around us an inevitable consequence of some master equation, some theory of everything? Or was there an element of chance in how it formed, and if so how big were those chances? Most people would like a theory in which we were not ridiculously unlikely.

    Near the end of “The Tempest,” in what has been taken as Shakespeare’s farewell speech, the sorcerer Prospero breaks his staff and declares, “Our revels now are ended.” And he goes on:

    “These our actors, as I foretold you, were all spirits and are melted into air, into thin air: and …leave not a rack behind.”
