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.
