Indeed, it would be the first particle outside of the Standard Model of particle physics to be discovered since the 1960s – and some physicists think sterile neutrinos could be a candidate for dark matter. The sterile neutrino would be even more difficult to detect because it would only interact with matter via gravity.

Big and important decisions about Canada’s energy future will continue to be made in the dark. The agency is the Canada Energy Regulator, and its mandate is “advising and reporting on energy matters.” Canada’s oil and gas sector is by definition 0% decarbonized – fossil fuels are hydro carbons. Conclusions.

Some business matters are best and properly kept quiet.

The first is a class of theories where matter fields and gravity live in a spacetime whose geometry changes with the probed scale, or are even fractal. The Euclid mission will hopefully unravel some of the secrets of dark energy in this decade. Can you tell us about your most recent research?

Today, in a research article published in the same journal Science , my colleagues and I have provided what we consider to be the most definitive evidence yet that the AMO doesn’t actually exist. Dark grey region bounds 68% of the simulations while light grey region bounds 95% of the simulations. Background.
