Beyond the Standard (cosmological) Model with Leonard Susskind
About | Information | History | Online | Facts | Discovery
NOTE: Audio becomes in-audible at the 3:25 mark but comes back at 4:19 Colloquium given by Leonard Susskind on Sep/9/2009 at The Perimeter Institute for Theoretical Physics in Waterloo, Ontario, Canada. Abstract: The Standard model of Cosmology consists of a package of ideas that include Cold Dark Matter, Inflation, and the existence of a small Cosmological Constant. While there is no consensus about what lies beyond the Standard Model, there is a leading candidate that also includes a small package of ideas: A Landscape of connected vacua: the idea that the universe started out with a large energy density, and Coleman DeLuccia Tunneling between vacua. An additional idea that comes from string theory and black hole physics is the Holographic Principle. I will explain how the various ingredients for a "post-standard-model" standard model fit together.

I just realized that he's been using a hockey stick as a pointing stick. I love this guy.

The quality is so bad. But it's better than nothing! Thank you for uploading these.

In the multiverse I'm a ghost of myself.

I would like to propose a dark matter candidate not mentioned in this presentation. The dark matter candidate is neutron groups. A neutron group is a group of two or more neutrons which are bonded together and can be described as an atomic nucleus without the protons and of course no orbital electrons. Such neutron groups would be stable just as neutrons in an atomic nucleus are stable.
A single independent neutron will decay into a proton and an electron with a mean lifetime before decay of around 15 minutes. A neutron group does not decay just as a neutron in a nucleus does not normally decay.A neutron group would be invisible an unaffected by light.

Sorry but all this talk is non sense if you do not believe in ALMIGHTY as the great designer.

just an update- a new Era for physics and Math will begin , a rupture for a time for ABSTRACT - is cosmic Era boys we need to afford more.

Excellent sound recording.

This man is a genius: He talks about one of the most complicated theories human kind has ever come up with in a way like I would be telling you where I bought the milk this morning. Fascinating....

mrtp and all, I'd like to share a book with you.
It is the core book of Falun Dafa entitled 'Zhuan Falun'. It talks about spiritual things from a scientific perspective. It talks about other dimensions, the soul, the cosmos in the microcosm and the macrocosm, supernatural abilities, karma, healing, the true history of mankind, transcending the 5 elements and leaving the 3 realms and many many other fascinating things.
It is a spiritual science of the highest order. I'll give you a copy and you can take a look if you like, totally up to you ofcourse:

Great talk, terrible recording. The audience's laughter is 10x louder than Leonard and completely distorts the signal.
-
what if the different vacuum states (vacua) are not spread across spacetime, but superposed?
-
any when/where info ?.....new? more coming ?
-
superb content !.....go Lenny go
