State of the Universes Part 3

What do we really know about the universe? What mysteries are today's top cosmologists investigating? Join a discussion with leading cosmologists (Katherine Freese, Neil Turok, Lawrence Kraussto) to hear fresh perspectives on some of the deepest questions in modern science: What is the mysterious dark matter that fills intergalactic space? Was there another universe before the big bang, and what will happen to ours in the distant future?

Ms Freese says something that is at the same time completely true and preponderantly underestimated: that we need to develop new theories that account for those phenomena yet unexplained. i dont understand why some, maybe most, physicists see available theories as the final thing, as if they covered everything, as if unifying the standard model with relativity would be closing the deal. well, no, da. dark energy and matter, and the pre-bang remain misteries.

I dont like krauss, he is overconfident in his perspective of physics and indulges turok along with all string theorists for havind a 'aesthetical conditioning' in their way of interpreting the universe. I dont like it, because his own perspective is not impressive, just corolaries of obvious things. and his lectures tend to be simple narratives instead of an actual divulgation of the concepts of physics.
