Mysteries of dark matter, dark energy and their possible connection to neutrino

Existence of dark energy, dark matter and non-zero neutrino mass are three most exciting discoveries of recent years. Though we know dark matter and dark energy and neutrino mass exist their fundamental particle physics origin is a mystery. More excitingly, the similarity between the energy scales of dark matter, dark energy  density and neutrino mass  raise the question: "Are they related?" I will explore how such connection could be there in nature and their cosmological consequences and how that can be probed by near future cosmological experiments which measure cosmic microwave background and large scale structure of the universe. I will also discuss some of the modified theories of gravity which explains dark energy and how neutrino can be a probe to such theories of dark energy.
