Cosmologists Cast Doubt on Inflation Evidence

by Jason Major March 24, 2014

It was just a week ago that the news blew through the scientific world like a storm: researchers from the BICEP2 project at the South Pole Telescope had detected unambiguous evidence of primordial gravitational waves in the cosmic microwave background, the residual rippling of space and time created by the sudden inflation of the Universe […]

We’ve Discovered Inflation! Now What?

by Brian Koberlein March 17, 2014

Days like these make being an astrophysicist interesting.  On the one hand, there is the annoucement of BICEP2 that the long-suspected theory of an inflationary big bang is actually true.  It’s the type of discovery that makes you want to grab random people off the street and tell them what an amazing thing the Universe […]

That Moment When the “Father of Inflation” Learns of the Detection of Gravitational Waves

by Nancy Atkinson March 17, 2014

Andrei Linde, a professor in the Department of Physics at Stanford University, is one of the main authors of the inflationary universe theory, that the universe underwent a brief but remarkably accelerated expansion immediately following the Big Bang. Today, scientists announced that they’ve found direct evidence of primordial gravitational waves, which would provide a “smoking […]

Landmark Discovery: New Results Provide Direct Evidence for Cosmic Inflation

by Shannon Hall March 17, 2014

Astronomers have announced Nobel Prize-worthy evidence of primordial gravitational waves — ripples in the fabric of spacetime — providing the first direct evidence the universe underwent a brief but stupendously accelerated expansion immediately following the big bang. “The implications for this detection stagger the mind,” said co-leader Jamie Bock from Caltech. “We are measuring a signal […]
