In terms of new ideas, things have been pretty dull in the physics community lately. However, there have been a few negative experimental results that are bad news for some old ideas and favorable news for the model I’m describing in this blog.
Take sterile neutrinos, for instance. Physicists have been looking for them for decades, and now the Daya Bay Reactor Neutrino Experiment in China has reported finding no evidence for then in a seven-month experiment. In our model, they don’t exist. Every neutrino is sterile half the time, but that’s a different concept entirely.
Also the latest results from the Planck satellite have been published, and they all but rule out a couple of the simplest inflation models, which are very different from our model of inflation.
In collaboration with the Planck group, the BICEP2 group has reexamined their announced finding of evidence for primordial gravitational waves and has concluded that what they saw was probably just dust. However, gravitational waves do exist in our model, so we just need more sensitive experiments to find them.
