## cosmological inflation

Is the Universe finite or infinite? Is there infinity inside a black hole? Is space infinitely divisible or is there a shortest length? We talk to philosophers and physicists to find out.

A quick tour to some of Hawking's most significant achievements.

The Astronomer Royal examines the evolution of our Universe and the important role of the constants of nature in this filmed public talk.

Yesterday cosmologists at the University of Cambridge delivered their verdict on a major breakthrough that rocked science this week: the announcement of the BICEP2 project of direct evidence for an inflationary theory of the Universe and the existence of gravity waves

Is the Universe finite or infinite? Is there infinity inside a black hole? Is space infinitely divisible or is there a shortest length? Can infinity occur at all in the cosmos or is it a mathematical construct? Find out more in our podcast with Anthony Aguirre, John D. Barrow and George Ellis.

Cosmologists gathered in the Netherlands last week to discuss a new view of the Universe. *The Universe as seen by Planck* was an international conference to discuss the recently released scientific results from the Planck satellite, including two particularly striking snapshots of the early Universe.
