I am honoured to be scheduled to give a closing talk at a conference this month at Imperial College. Outstanding Questions for the Standard Cosmological Model will overview the evidence for and against the so-called standard model. It will also address alternative competing models. This will be an international conference attracting many important researchers. Forgetting for a moment what I will say, we will hear from some scientists previously mentioned in this blog.
Alain Blanchard of the Midi-Pyrenees Observatory is not well-enough known outside Europe. He has written the authoritative book GALAXIES AND COSMOLOGY. Using ESA's XMM-Newton satellite, he has gathered evidence that Dark Energy Doesn't Exist.
Professor Roger Blandford was once a student of (Astronomer Royal) Martin Rees. He was co-developer of the Blandford-Ivanek process for Black Hole jets. Today he is director of Stanford's Kavli Institute of Particle Astrophysics and Cosmology. Once he reluctantly lectured about "dark energy." In his own closing talks at the AAS HEAD Meeting in October and the GLAST Symposium in February, he did not mention DE. He did comment about "Lorentz Invariance," or a changing speed of light.
Lawrence Krauss of Case Western Reserve University is a prolific author and contributor to publications like Scientific American and New Scientist. He has wondered how the cosmic microwave background "proves" inflation when the scale-invariant spectrum, which is predicted by inflation, is ruled out by both COBE and WMAP data. At his AAAS talk last month he called current cosmology "observation-driven" rather than model-driven. He also said that supernova data "naively implied that the universe was accelerating." He also wrote THE PHYSICS OF STAR TREK.
The "standard model" or Concorde cosmology is a hodgepodge of speculations dominated by an invisible "dark energy." It relies on a repulsive "inflaton" driving initial expansion, another repulsive energy causing present acceleration, and our Ptolemaic world in the middle. None of these imagined energies can be observed in a laboratory, just like the Emperor's New Clothes. The Universe of this cosmology is flat, like the Earth.
I hope that other friends from Imperial College, the UK and Europe can make the trip to London. My talk is scheduled just before lunch, 12:30 PM GMT on March 29. (There will be summary talks after lunch.) In case you are not registered for the conference, nobody pays much attention to that on the last day.
