Penrose has given this Before the Big Bang talk repeatedly over several years and it has developed. Some new thoughts, new cartoon drawings.

Here on YouTube is a version he gave 31 October 2007 at George Mason University (Fairfax, Virginia, near Washington DC). It comes in several segments. The first ones are his talk and the last ones are devoted to responding to questions from the audience.

I should also get the link to the version of the talk he gave at Perimeter Institute.

Here is the Perimeter version given 12 September 2006, more than a year earlier

Before the Big Bang: an Outrageous Solution to a Profound Cosmological Puzzle
Roger Penrose - University of Oxford

In some sense, other things being equal, LATER IS BETTER. However I have watched the November 2005 version given at Cambridge, perhaps the earliest version online, and like it very much. Although only voice+slides, not full video, the delivery is very clear.
Does anyone have another version of this talk that is online?

I'd prefer this to the popular media treatment of his ideas, and how they come across in an interview for general audience, because there too much gets garbled or diluted. I prefer to hear Penrose himself giving the whole Before the Big Bang talk with his own slides, where it is aimed at a smaller audience.

Thank you Marcus! I' ll give an opinion when I'm done... what a goof!
 
Great! Just for completeness here is the November 2005 slideshow version he gave of the same talk at Cambridge

People will find what they like to watch best but if I were recommending I think maybe I would suggest watching the Cambridge slideshow first, and then watching some of the George Mason University sequences on YouTube.
He seems more animated and excited there than he does in the Perimeter version, and I think some new ideas have crept in.
So I would say watch both the earliest and the latest versions available online (November 2005 and October 2007).

YouTube is harder to watch because broken up into 10 minute segments.

The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...
