Big Bang models for the creation of the universe make a variety of predictions that come out of the equations of the models. As technology for astrophysical sciences improves and computer simulations and observational methodologies are generated and tested by a variety of means, some sensitive tests are now being done to check the validity of the Big Bang predictions. For example, the rate at which the universe is expanding, star formation and life cycles, and cosmic background radiation distributions have been tested for some number of years and support Big Bang predictions (as well as inflationary models, which are refined Big Bang models).
A new test has been done and reported in the latest edition of the scientific journal Nature. Detailed studies of the cosmic background radiation map of the universe have revealed small asymmetric patterns and clumping in the data, as predicted by inflation. However, at very small levels there is a ‘smoothing’ effect that has been observed that matches a prediction that in the early universe neutrinos could have affected the gravitational interaction of clumps of matter. Very interesting, indeed!
