Lecture: John Carlstrom – What Do We Know About The Big Bang?

John Carlstrom gives the plenary lecture at the New Horizons in Inflationary Cosmology Templeton Conference organized by the Stanford Institute for Theoretical Physics.

Our understanding of the origin, evolution and make-up of the Universe has undergone dramatic and surprising advances over the last decades. Much of the progress has been driven by measurements of the fossil light from the big bang, called the cosmic microwave background radiation, which provides us with a glimpse of the Universe as it was 14 billion years ago. This talk will discuss what we know about the Big Bang and how we learned it. We will also talk about the new questions we are asking about the origin of the Universe and the experiments being pursued to answer them, peering back to the beginning of time.

Series of New Posts: Lectures, talks, podcasts, etc…

I will be starting a regular series of posts of lectures, talks, podcasts, etc. If you have requests for topics, please feel free to comment on this post or send me a message via the contact links. The first of these posts is below:

On Oct. 7, 2015, Perimeter Institute Director Neil Turok opened the 2015/16 season of the PI Public Lecture Series with a talk about the remarkably simplicity that underlies nature. Turok discussed how this simplicity at the largest and tiniest scales of the universe is pointing toward new avenues of physics research and could lead to revolutionary advances in technology.

Possible signature of dark matter annihilation detected

A false-color image of the anomalous gamma-ray emission from the central region of the Milky Way galaxy; this emission is suspected of coming from dark matter annihilation. In this image, the emission from conventional sources has been subtracted from the total. The region covers roughly five degrees; the brightest emission is colored red and faintest blue.

CfA astronomer Doug Finkbeiner and a team of colleagues claim to have identified just such a signature of dark matter annihilation.

Kaon decay – asymmetry between matter & antimatter

 

Ground-breaking research could challenge underlying principles of physics

Dr Nicolas Garron, a Research Fellow in the Centre of Mathematical Sciences, has helped to devise the first theoretical calculation of how the behavior of kaons differs when matter – anything with mass, such as the world around us – is swapped out for antimatter – made out of similar particles with opposite charge.
