Have Cosmologists Lost Their Minds in the Multiverse? (Op-Ed)

By Luke Barnes, University of Sydney and Geraint Lewis, University of Sydney | May 14, 2014 09:23pm ET Captured From: http://www.space.com The recent BICEP2 observations – of swirls in the polarisation of the cosmic microwave background – have been proclaimed as many things, from evidence of the Big Bang and gravitational waves to something strange called the multiverse. The multiverse theory is that our universe is but one of a vast, variegated ensemble of other universes. We don’t know how many pieces there are to the multiverse but estimates suggest there many be squillions of them. But (if they exist) there … More

Pinning Down the Universe’s Rate of Expansion

Captured From: http://physics.aps.org Paul Hooper at Spirit Design, with Mat Pieri and Gongbo Zhao, ICG Visualization of the experiment carried out by the Baryon Oscillation Spectroscopic Survey (BOSS). Redshift data from 140,000 quasars collected by a 2.5-meter telescope at Apache Point, New Mexico, provide the most accurate measurement to date of the expansion rate of the Universe.

New Quantum Theory Could Explain the Flow of Time

Captured From: http://www.wired.com BY NATALIE WOLCHOVER, QUANTA MAGAZINE 04.25.14 As a hot cup of coffee equilibrates with the surrounding air, coffee particles (white) and air particles (brown) interact and become entangled mixtures of brown and white states. After some time, most of the particles in the coffee are correlated with air particles; the coffee has reached thermal equilibrium. Image: Lidia del Rio  

Big Bang backlash: BICEP2 discovery of gravity waves questioned by cosmologists

Captured From http://www.washingtonpost.com   Video: In March, scientists from the Harvard-Smithsonian Center for Astrophysics announced their discovery of gravitational waves created at the dawn of the universe. These waves were created in a period of rapid expansion called cosmic inflation. This new evidence could prove the definitive confirmation of the inflation theory. But other researchers are not convinced. By Joel Achenbach, Published: May 16 E-mail the writer
