Description

Neil Turok joins Brian Greene to describe his new ideas for curing the big bang singularity and providing a natural dark matter candidate, all while avoiding the conventional paradigm of inflationary cosmology.

Brian, please don't ever stop doing these. The one-on-one interviews by you are by far the best format, don't ever change please!

Finally a longer segment with someone who is not afraid of being humble and critical at the same time. Great interview and great counter talk to all the hyperbole from string theorists..

Neil Turok is one of the bright minds of these days. Happy to see him on this channel.

I must say, this seems to be the most compelling anti-inflation framework ever proposed.

As a long time follower of theoretical physics I am positively thrilled to witness this conversation outlining the solid theories and proposals of Neil Turok. To be able to watch two of the best communicators in science discuss these topics is an absolute treat. Also, I must add, that to hear that Brian felt inspired in the end to follow up on several of the topics raised by Master Turok, leaves me feeling positive about how I have held both of these men in highest regards for years. It did not have to go that way .. the entire world can learn from everything about this. In the end, we're all in this together .. and we're all on the same team. Go Science!

That Brian Greene and Tracy Day started the WSF was a brilliant idea, and the series of interviews on a wide range of topics and at a level understandable (mostly!) by non-experts is marvellous. Long may they continue. As a retired CERN experimentalst I discovered that well-know theorists would come to CERN for a sabbatical, or perhaps over the summer, but would only find out later by reading articles in New Scientist. No doubt these people gave seminars to the Theory Department, but they almost never gave seminars at a level understandable by none experts. And after I started to discover the mess with the QM Measurement Problem (this was never mentioned during my degree course) I also discovered that every day on my way to coffee I passed within 50 metres of the office of John Bell. Thus, I once sent him a message to suggest he give a talk on the issue, but without success. Thus, maybe if someone from the CERN theory department reads this, they may consider whether it should expand its role outside the Theory Conference Room. In the mean time thanks goodness for Professor Greene!

Neil Turok’s has got to be one of the clearest thinkers out there. He is always a pleasure to listen to.
