CafeLitt 173: The Strange case of "Dark Energy": Was Einstein Right?

Thu 17 Jun 2010, 19:00, by Dr. Omid Saremi, at Bistro Burritoville:3rd floor, 2055 Rue Bishop, Montreal,QC (Map)

Every time we stargaze, we are humbled...We start contemplating about our "cosmic origins": Where do we come from? Was there a beginning? Will there be an end?
One of the most astonishing discoveries of humankind in the past century, is to reveal that we live in an expanding universe..
Confusingly, the expansion of universe seems to be accelerating!! This has been perplexing physicists. It will have unthinkable consequences. In particular, it implies that the vacuum itself, or the state of "nothingness", should have some weight!
Is "nothingness of vacuum" made of "something"? Is the vastness of Cosmos, filled with "some dark stuff" that physicists have just begun to comprehend? Did Einstein get this right? Or we need to ...?
In this talk, we will share our confusions.

About us

CaféLitt is not a place; it is a gathering of minds. We are a group of mostly Persian young students, scholars and professionals who gather every Thursday evening around 19h00 in a café to discuss various subjects and share different ideas, ranging vastly from history to science, from literature to fine arts. We started these gatherings on Jan 18th, 2007. Each week, one of us takes the responsibility of presenting a topic (in Persian, English or French) for about an hour in a subject s/he is intimately familiar with or has an expertise in. Afterwards, the evening turns into a discussion forum and all members of the audience will have an opportunity to ask their question(s) and share their points of view.
CaféLitt is open to all comments, suggestion, collaboration and new ideas. CaféLitt provides an unparalleled opportunity for learning about culture, science and philosophy in a relaxed and friendly environment, and for sharing your knowledge and expertise with like-minded members of your community.
CaféLitt is officially registered as a non-profitable group and is a nonpartisan, nonreligious and nonpolitical entity.
